Off Grid Power in Liberia 

We won!

We’re honored to announce that All Power Labs is part of the winning team for the Water Abundance XPRIZE 2018. APL was the technical lead for the Skysource/Skywater Alliance team, and brought gasifier based power generation, plus a unique use of water vapor from biomass, to the larger problem of making atmospheric water generation machines truly usable in the world.

XPrize Water Abundance Winners on stage

The $1.5M award was announced at the XPRIZE Visioneering 2018 event in Los Angeles, October, 20, 2018, bringing to a conclusion a 2 year long competition involving 98 contending teams from 27 countries. The prize was launched in 2016 at the United Nations in New Delhi, with sponsorship by the Tata Group and Australian Aid. Both groups are continuing their involvement to ensure this innovation gets to market and doesn’t just stop with a flurry of press releases!

The competition has aimed to alleviate global water scarcity by accelerating technologies that harvest fresh water directly from air, with 10x improved economics and usability vs current atmospheric water harvesting tech. The Skysouce/Skywater/APL team won by delivering a novel biomass gasification based high-volume water generator that can be used in any climate, meeting the competition parameters of extracting a minimum of 2,000 liters of water per day from the atmosphere using 100 percent renewable energy, at a cost of no more than 2 cents per liter.

The novelty of the Skysouce/Skywater/APL solution is the integration between the standard APL PP30 Cogen-CS power generation system, and the standard Skywater vapor compression cycle atmospheric water generation (AWG) machine. More specifically, we developed a biomass drying system placed between the two products, so that water vapor from the drying process can augment the humidity intake to the AWG machine. This enabled us to create an artificial high temp / high humidity environment for the AWG machine, meeting or exceeding the usual tropical conditions required for good AWG water yields. We did this while operating in the cold low water holding air of Berkeley, CA.

In practice, a standard AWG machine won’t really work in Berkeley late Fall air conditions. But we used “Berkeley air”, augmented with biomass, to exceed the high metrics of the competition and win against competitors working in the tropics!

All of us in the biomass powergen industry consider water in biomass a problem to get rid of. Though this contest, we discovered that it can, in fact, be a tremendous resource for co-production of potable water, while simultaneously delivering the usual electricity and sequestration of carbon through biochar. We realized that biomass is a major untapped water resource with global availability. It should be added to the list of water resources typically assumed: rivers, lakes, rain, wells, ocean, and air.

For a video summary of the competition, and some shots around APL while we were testing, see here for the XPRIZE produced video of the process.

Product Prototype: WEDEW Watertainer

Water container at Verge conference

Looking towards productization, we designed the components for the XPRIZE test rig to fit inside a standard 20′ shipping container. This container-based integration, with side wall openings for access, is the form factor we plan for ultimately bringing this Power, Water and Carbon Sequestration solution to market. The first containerized product prototype is shown above and below while being demonstrated as part of the microgrid at the Verge conference in Oakland in late October.

The WEDEW Watertainer uses the standard PP30 Cogen unit, with full utilization of its CHP features to enable the controlled drying process. All of our work on the XPRIZE project was enabled by the new CHP features of the Power Pallet: in this case applied to a highly controlled drying process for specific temp and humidity flow delivery to the AWG machine.

Development of this new product will continue over the coming Winter and Spring. We expect to start pilot projects in the later half of 2019. If you are interested in being an early customer, funder, or enabler of the first wave, please write us at: “”

Carbon Management Through Green Waste Management


Partners Wanted For Waste To Energy Project Trials

You likely already know that APL’s technology provides significant value in the areas of waste management and renewable energy, while also making substantial contributions in the fight against climate change. Turning green waste into energy is a win-win-win solution. As pointed out in an article this week in The Guardian, “Agricultural waste, which would otherwise be a major source of greenhouse gas emissions if burnt, could instead be turned into a biochar – a process that produces more energy than it consumes – and the biochar could then be used to enrich agricultural soils with carbon. Research suggests that biochars not only boost crop yields, but could lock away carbon for several thousand years.”  With recent significant improvements to our technology, we believe the value proposition is now stronger than ever.

However,  you may also know that biomass gasification isn’t yet as easy to finance as solar, which is a barrier to scaling and realizing the full value of the technology. So, to make our solution more accessible, we’re now offering turnkey waste-to-energy (WTE) services, wherein APL or its affiliates will own and operate the equipment at your location. You would not be responsible for the capital cost of the equipment, and- because we can dispose of waste and generate energy more cheaply that other technologies- our fees would simply come from the waste management and electricity use savings from using our services. There’s also an option to provide onsite heating and cooling as well, if needed.

This fee-for-service model provides a simple WTE solution that offsets both waste management and power consumption costs for customers. The compact, modular, and turn-key design of the Power Pallet enables us to scale the service as needed. Projects will be operated in a net metering situation similar to solar, but would have the additional value streams of biomass waste processing and provision of heat and cooling services, not to mention the flexibility of having mobile units.

We plan to start offering our WTE service model here in Northern California, then across the state, then wherever there’s a good fit. We are targeting the first installations to begin producing power in the SF Bay Area in the second half of 2017. This pilot program will also be used to refine the business model in preparation for general release in 2018.


This work is being enabled in part with strong support from the state of California; the California Energy Commission has awarded us $3M in grants in recent months to continue to refine our products, making them more efficient and easier to use.

The need for this kind of solution clear: climate change is causing a mounting biomass solid waste crisis, which is in itself contributing significantly to climate change. We intend to help break this cycle. Last fall, we started sounding the warning about the impacts of climate change on our forests here in California, a crisis that continues to deepen. The latest climate clarion call is from Southern California, where the transition to a landscape wholly devoid of urban trees––in parks, on campuses, and in yards––could happen in just the next generation.

pallet to chip

We are now looking for qualified demonstration sites to conduct the most near-term WTE projects, with the following characteristics: located within two hours of the San Francisco Bay area, significant onsite energy use  (around 100kW or more), and onsite biomass waste processing that’s either revenue neutral or a cost center. If these characteristics describe a site that you own or to which you have access, and which you would like to be considered, please fill out the attached form. We will get back to you right away if your site fulfills the requirements for a  successful project.

OPEN HOUSE this Friday night, 5-7pm
Our regular monthly open house is coming up this week. Please RSVP so we know how many guests to plan for, then drop by for pizza cooked in a gasifier-powered oven, plus cold beer and soft drinks, and all the gasifier talk you can eat.

Negative emissions tech: can more trees, carbon capture or biochar solve our CO2 problem?
As noted above, The Guardian newspaper in the UK has a thoughtful look at this promising question this week. Click here to read all the details.

The business, and climate, case for biomass
The former Mayor of New York City, Michael Bloomberg, and the former head of the US environmental group Sierra Club, Carl Pope, have written a much deeper dive into the same topic as the Guardian article in their new book “Climate of Hope.”


They write, “We have phenomenal machines to do this job — they are called plants, and they exist to take CO2 out of the atmosphere and turn it into organic matter in the soil. (Certain kinds of rocks also sequester CO2 in very large quantities, but our ability to influence the pace of such mineralization is much more limited than our impact on the biosphere and plant life.) What does it take to trip the biosphere — the globe’s collection of animals and plants — into a massive carbon-storing mechanism?”

The climate crisis is making new heroes. Meet Matt Rogers, founder of NEST
Every day, all over the world, new heroes in the climate struggle are emerging from unlikely places. Case in point: Matt Rogers. After working at Apple on some of this century’s most iconic products, Matt left to found NEST, which makes home thermostats. Not very sexy, perhaps, but their combination of sleek design and innovative performance is driving users to install millions of them. This, in turn, has already avoided the equivalent of more than 2 million tons of carbon emissions from burning coal. You can learn more about Matt’s  impact, and the work he’s enabling, in this Medium post.

As we’ve mentioned previously, California is in the midst of a solid waste crisis, driven by the twin drivers of closing biomass plants and a forest health crisis that’s killed hundreds of millions of trees. We can help you lower your electricity bills and waste disposal costs at the same time. To contact us to discuss your project, email or call toll-free +1 888-252-5324.

APL wins new grants from the California Energy Commission
The State of California has long been a leader on environmental issues, and has historically invested early in promising technologies. That’s certainly true with biomass-to-energy projects: in the last several months, APL has been awarded $3 million in competitive grants from the CEC, and is shortlisted for $3 million more. The first $1.5 million award is for Combined Heat and Power (CHP) projects utilizing the Power Pallet, and the second grant, also for $1.5 million, is for a higher capacity Powertainer with CHP and a dedicated biochar offtake.  In both cases, APL was the highest-scoring applicant. APL also received a high passing score for a $3 million grant to create 2MW of Powertainer projects; that project is still working through the system, as the CEC got more winning projects than they currently have funding for. We’re cautiously optimistic those projects will move forward as well.

Highlighting recent projects
We continue to install new projects regularly, all over the world. Here are two recent projects we wanted to highlight. The first, in Costa Rica, uses waste from coffee production to make energy to run their roasters and processing equipment in a remote community. The second, in northern Ghana, powers a school using wood waste from a nearby mill.

    iCafe-talking coffee in Costa Rica. In this video ( narrated in spanish ) you can see how iCafe is able to provide the high-output energy they need to operate their processing operations even in their remote, mountainous location. The Power Pallet is uniquely positioned to serve in this use case: unlike other renewable energy sources, which are not on demand and do not have sufficiently high energy density (unless they are paired with hugely expensive battery banks), the Power Pallet can be used  as needed and provides a high level of so-called “productive power” for energy-intensive agricultural operations.


    Modern Star, shining bright in Ghana In February, we installed a Power Pallet at the Modern Star school in northern Ghana.  The project is designed to operate on locally-sourced wood waste from a nearby mill. Once the Power Pallet was installed, the wiring was connected and the unit supplied enough power to electrify all six buildings on campus.

We’re happy to be doing our part to solve the challenges of energy access and climate change.

Solving Climate Change: Project Drawdown
Last week, Paul Hawken’s Project Drawdown released its long awaited, and deeply researched, guide to reversing global climate change. It is an impressive, incredibly ambitious work, and full of surprises. Case in point––the #1 thing we can do isn’t switch to wind or solar, it’s….better manage refrigeration.

All of the solutions are scored and ranked according to impact and cost. Not surprising to anyone who has been following our work, supporting biomass energy ranks pretty high. And, when combined with other cross-cutting solutions like biochar production, waste-to-energy development, and regenerative agriculture, it’s easily in the top ten.

LA Times: APL biomass gasification “one of the most promising technologies”

Flexible clean energy that helps solve climate change?

That’s what the LA Times calls biomass gasification from All Power Labs–
“one of the most promising technologies” to help solve the forest health crisis in California.

Last week the Los Angeles Times, California’s largest newspaper, published an editorial exploring solutions for one of the toughest problems facing the Golden State: how to preserve our leadership on climate change while dealing with a crippling multi-year drought that has left more than 100 million trees dead. The solution is to convert all that dead biomass into on-demand energy, and along the way do something impactful to address climate change. Click The Image Below For Link To Article

The piece sums up the climate potential well: “Aside from their main output, electricity (which can be fed into the grid), the units generate a key byproduct, biochar, a charcoal-like substance that is almost pure carbon. When applied to soil, biochar stimulates plant growth and reduces water consumption, which makes it a valuable commodity in water-stressed California fields. In essence, biochar is carbon that would otherwise have been released into the atmosphere, which makes All Power’s gasification process not just carbon neutral but carbon negative.”

The solution that unlocks this potential at scale is the Powertainer, a mobile 150KW power plant that turn waste forest biomass into energy, heat, and biochar. Sponsored by a grant from the California Enegy Commission, APL has been developing a commercial version of the Powertainer modeled on a design we first made in 2012 for the US Department of Energy. Shown below is the new version at a green waste yard testing facility just minutes from APL’s headquarters in Berkeley. As you can see, the unit is easily moved to and from project sites. No expensive civil works are required–just put it on the ground, plug it in, and add fuel.

Over the last two years we have been developing the Powertainer we have received significant interest from potential customers. Now that we are planning to begin deploying units in the field,  we would like to gauge the current level of interest in the product.

A menace in our mountains: the terrifying climate truth behind California’s fall forest colors

Fall in the United States is known for the colors in New England, as trees turn to the warm shades of autumn before dropping their leaves. That sort of change historically wasn’t common here California, where our forests are mostly evergreen pine trees. At least, that used to be true–but not anymore.

Thanks to drought and climate change, there are now 66 million dead trees in California, a number that may triple by year’s end. That’s almost one million linear miles of dead biomass, enough to stretch to the moon and back twice. But, when combined with a forward thinking energy policy, this crisis is also creating an unique opportunity to solve the twin challenges of affordable renewable energy and climate change at the same time. APL’s Tom Price just published this Medium post that outlines what’s at risk, and how APL’s gasification solution could save not only California, but the whole planet.

If after reading this piece you’re interested in seeing the new 150kW Powertainer in person, please see below for an upcoming event at our Berkeley factory.

National Science Foundation awards All Power Labs $225,000 grant to develop next-generation reactor.NSF

Last month, APL was awarded a prestigious $225,000 Phase 1 grant from the National Science Foundation’s Small Business Innovation Research (SBIR) program, to support our research and development of our next generation gasifier reactor.  Specifically, this grant “enables the research and development of a new hybrid fixed-fluidized biomass gasifier design that allows for a higher carbon conversion efficiency over a far wider range of feed stocks than what current commercially available biomass-to-electricity technologies are able to offer.”  APL’s Dr. Jay Hasty will be the Principal Investigator leading the team doing this important work.


APL powers events across Silicon Valley and beyond, spreading the word about “energy for productive use.”

This summer APL presented at (and powered!) several high profile events, all focused on reinforcing a perspective that’s gaining traction in the global renewable energy community:  We need to provide more than just lighting; true energy access means energy for productive use. That kind of high amperage power, to enable value adding activities like running machinery, is something off-grid solar can’t provide, but it’s an ideal use for compact biomass gasification gensets.

In June  we presented these ideas at the Clean Energy Ministerial in San Francisco, the implementation-focused follow up to the COP21 Climate Accords in Paris last December, at which APL also presented.  That makes APL the only company in the world to exhibit carbon-negative technology at both events.

We then flew over to Hawaii to help power a microgrid running the first VERGE Asia Pacific Clean Energy Summit, getting help from Governor David Ige to refill a Power Pallet operating on locally-sourced macadamia nut shells.

We then powered the dining tents during the Social Capital Markets SOCAP conference in San Francisco, and went straight from there to Santa Clara, the heart of Silicon Valley, helping power the microgrid at the VERGE conference and participating in their startup showcase.  We wrapped up our tour at the International Off Grid Renewable Energy Conference in Nairobi, Kenya, contributing to the “Emerging technology solutions for off-grid renewable energy systems” session, and are now home getting ready for our biggest event of the year–unveiling our new Powertainer.

Powertainer demonstration coming this fall

APL is preparing to publicly unveil our new 150kW Powertainer, designed to help address forestry waste management as well as clean energy and climate solution needs.

Two years in the field-and counting

Two years in the field and counting — APL technology passes key new product milestone

As world leaders gather in New York this week to celebrate Earth Day, and to sign the COP21 Paris Climate Accords,  here at APL we’ve been doing some celebrating of our own.

If you have been in the renewable energy field for a while, you know that new technologies don’t come along that often, and rarer still are the ones that pass two years of service in the field.

That is why we’re so pleased to announce that our v5 Power Pallets have just done exactly that.  For two years now, even through the Ebola crisis, the BWI Renewable Energy Center in Kakata, Liberia has been making free energy for their school from biomass (in their case using expired rubber tree chips as fuel) via three of our Power Pallets.

To celebrate this key product validation milestone, last month we held an Open House at BWI. Our local staff showed off their work to local dignitaries, NGOs, and business leaders, and as a result of their successes negotiations are now underway to expand the project.

IMG_4450  IMG_4509
This project was originally sponsored by USAID and organized by EcoPower Liberia. Since then, we’ve been managing the facility’s operations and using BWI for an intensive R&D facility, intentionally running parts to failure in the toughest conditions we could manage.

We’ve learned a lot over the last few years and have integrated that knowledge into everything we do here in Berkeley. Congratulations to everyone on the APL Liberia team for your successes– you’re proving every day just how valuable energy from biomass can be.

When “renewables” aren’t renewable- tough choices ahead for policy planners

Last week the New York Times published a story about the impact of climate change on hydropower in Zambia. It highlights a topic that doesn’t get the attention it deserves, namely how a changing climate can affect the production of renewable energy.

As our weather changes, there will be times the sun doesn’t shine, the wind doesn’t blow, and the rain doesn’t fall. This in turn highlights one of the important features of using small scale biomass energy—it can be used rain or shine, day or night, and since it uses existing waste as fuel it’s all but impossible to run out of energy.

We hope this article sparks a broader conversation about resiliency issues in renewable energy, as we all work to address the twin challenges of energy access and climate change.

In Addis Ababa this week? Stop in to see Jim Mason at the Africa Climate Resilient Infrastructure Summit

Speaking of resiliency, if you are in Addis Ababa this week at the Africa Climate Resilient Infrastructure Summit, please make sure to meet up with APL’s acrisCEO/Founder Jim Mason. He’s there meeting with other technology companies and clean energy advocates to help map out how Africa can address rising energy demands in a world newly focused on sustainability and dependability in energy systems.

We’re Hiring: Engineers and Sales

APL is looking to make some immediate hires in our engineering and sales departments, across a wide range of interesting and challenging positions. The best people we end up with come from referrals from people familiar with our work, so feel free to share these openings with your networks.

Down the trail: saying goodbye for now to Brenna Sheldon

BPIMG_2244APL is blessed to have a team of incredibly talented, dedicated people working here. It’s a pretty tight knit group, so we’re certainly going to feel the absence of one who is leaving us. But that sadness is offset by happiness for the reason she’s leaving: to take the adventure of a lifetime.

Brenna Sheldon answered an ad for a position here a year and a half ago, and we immediately hired her–she has a radiantly positive attitude, a can do spirit, and appetite for learning and trying new things.  She quickly jumped into a big role in our sales department, and was key part of our outreach at the COP21 climate accords in Paris. (At R, with Sara Norris.)

But like we said, she likes a challenge–and she just took on one of the biggest. She won a coveted permit to hike the grueling 2,659 mile Pacific Crest Trail, and later this month will start her solo hike from the border of Mexico, all along the spine of the American west, to the border of Canada.

We’ll be heading out to meet her along the trail when she passes near here this summer, and know you’ll join us in wishing her a safe and rewarding journey.

Constant improvement: 2016 updates to the Power Pallet

APLLogoWithTagFadeShort10_1_2015 2

Gasification has been famously described as “all variables, all the time,” and wrangling those variables into a tractable form has been our work at All Power Labs since starting out with the GEK kit back in 2OO8.  Since then, we’ve released five complete generations of our gasification systems, and today Power Pallets are at work in more than 3O countries on six continents, and are supporting research at dozens of universities.

They deliver high-quality energy for productive use by turning waste biomass into on-demand, renewable, carbon-negative energy for far less than the cost of solar or diesel. (A recent video from the Huffington Post  highlights the Power Pallet’s potential impact on rural electrification.)

However, our technology can always be made better, and we are constantly making changes to improve its performance and ease of use. The purpose of today’s note then is to highlight the most significant changes that have been implemented over the last several months. We’ve made a strong value proposition even stronger. Take a look:




As of today, all Power Pallets now include the new 5.02 version of our pyroreactor (shown here on the left being manufactured this week in our shop in Berkeley.)

Quite literally the burning heart of the Power Pallet, the pyroreactor is the core element of our gasifiers; the current generation–the version 5–was first introduced two years ago. The v5.02 incorporates various changes to the hearth, materials, accessories, and manufacturing methods.

The most significant modifications changed the impact zone of the reactor air input, creating a more even and precisely located combustion zone.  This results in more complete tar cracking that occurs exactly where we want it, delivering a robust 40% reduction in tar production over previous generations, as well as a significant reduction in clinkering effects.

That means better performance and lower O&M costs.  And because the changes are taking place entirely within the hearth of the reactor, there’s no change to external sizing and configuration, so the overall compact footprint remains the same.







Heat Exchange Filtration

IMG_4080Another big innovation: a new secondary heat exchanger filtration system (seen here, at the far left of the Power Pallet), which reduces the amount of tar in the gas stream and increases the longevity of the power train. One of the features that distinguishes the Power Pallet from other gasification systems is our innovative and patented use of thermal management, utilizing “waste” heat from one process to drive useful reactions and processes elsewhere in the machine–for example, using the waste heat from gas leaving the reactor to dry feedstock before it goes into the pyroreactor.
The heat exchange filtration system is another innovation in thermal management and heat recycling. After the gas is used to dry feedstock, it is routed through the inner tubes of the heat exchanger. The engine vacuum is used to simultaneously pull ambient air into the outer shell of the heat exchanger, where the temperature differential between the cool air and the hot gas allows heat to be exchanged, cooling the gas coming out of the reactor. This causes suspended tars and volatiles in the producer gas to condense and fall out of the gas stream before it flows into the primary filter.

The heated atmospheric air is then routed through the engine’s air intake and mixed with the cleaned and cooled gas after it exits the primary filter. The heated intake air serves a second function, as it raises the temperature of the combustible air/gas mixture and thus avoids the condensation of water and other remaining trace tars entering the engine so that they can be completely combusted. The result is much cleaner gas pre- and post-filter, and a markedly lower O&M requirement for the engine.

CHPA few months ago, in another iteration on waste heat transfer that adds substantial value to the Power Pallet, we introduced a Combined Heat and Power (CHP) module.

This CHP module uses the excess heat from the working fluid in the engine radiator and runs it through a heat exchanger. We provide hook-ups to the outside of the heat exchanger so operators can use that thermal energy to heat water and put it to productive use, like drying crops and other agricultural processes.  An additional benefit of the CHP module is that is helps keep your engine running cool, reducing wear and tear.

We have also ensured that the CHP module delivers its thermal energy load without any reduction in electrical power output, meaning you can now get 1 kilowatt hour of electricity and 1 kilowatt of heat out of the same 1.2 kG of biomass. You can find more of the CHP module’s technical specifications and pricing here.




Stainless steel grate baskets

IMG_4083The perforated grate basket is one of the core elements in the APL gasifiers. It helps maintain a char bed at the bottom of the reactor that is ideally suited to maintain gas flow and sustain the reduction processes that are critical to the production of combustible gases from biomass waste. Refresh your understanding of how this basket is designed to work.
In order to ensure long uptime and reliability, we are now making the basket out of a very strong alloy of stainless steel, which resists corrosion and which our testing has shown is not prone to degradation.

The stainless steel grate basket is an improvement that was driven directly by feedback from our customers. We were getting reports from the field that over very long periods of runtime, the exposure to high heat and corrosive gases, combined with constant agitation, was causing degradation of the mild steel in the previous version of our grate baskets. This solution now solves that issue.




Continuous Feed Optimization

All Power Pallets now come with their electronics and feedstock hoppers ready to retrofit with an optional air lock system to enable easy automated filling for a customer-provided external feed system.

If you want to use a manual feeding process with your new Power Pallet, you won’t notice anything different. But if you’re interested in integrating APL’s continuous feed module and external fuel handling system with a Power Pallet that you already own, you can now do it without changing hardware.

Specifically, the hopper on all Power Pallets is now shipped with attachment points and wiring harnesses that will allow easy integration of the continuous feed module with its sensors, motor, and valve, should a customer decide that he or she would prefer to use a continuous feed system after receiving the unit. (Image: plugged bungs on the side of the feedstock hopper that would be used for continuous feed module feedstock level sensors in a retrofit.)

Because the APL continuous feed module obviates the need for an operator standing by to refill the Power Pallet’s feedstock hopper, this change enables customers to lower their O&M costs and thus provides a lower cost per kilowatt hour. You can see that system in use on this project at the Hybridnet in Terni, Italty.

Other recent performance improvements

There’s now a larger ash collection vessel for 24hr+ continuous run times, strengthened materials in the flare and exhaust, backfire-suppressing wiring and software changes, increased grid tie module control, an upgraded oxygen sensor, and much more. We also focused on usability issues, like adding an easily-accessible, weatherproof documentation holder right on the Power Pallet and improving the PCU automation interface.

All told, there are more than 30 changes and improvements to the Power Pallet in the last few months. With every improvement we make, we strive to ensure backward compatibility wherever possible, so it’s easy to upgrade your existing system to the latest performance.

We got a great climate deal at COP21–now what?

We got a great climate deal at COP21–now what?

We should all be rightly happy about the outcome of the COP21 climate accords.  Now comes the hard and exciting work–how do we reach these climate targets? The answers are sobering, and one take away is absolutely clear: solar and wind alone won’t do it. We’ll need carbon negative energy, and on a massive scale.

prs    arcs
APL brought a big team to COP21 to share a simple message: affordable, renewable, carbon negative energy from biomass is here, and ready to help solve the twin challenges of energy access and climate change.

Paris was a fantastic time to discuss climate friendly energy with so many committed players all in one location, such as Andrew Herscowitz (top), the head of the Power Africa program, California’s Senate leader and renewable energy champion Kevin de Leon (bottom), and many more.

The importance of carbon negative energy bears repeating; as our friend Noah Deich at the UC Berkeley Center for Carbon Removal points out, almost every single scenario to get us to below +2 Celsius warming has to include large scale deployments of carbon removal technology. (Click here to read an early draft of a report he’s creating to explain the options and opportunities.)

Liberia APL Project in Huffington Post TV feature
We’re doing our part by getting to work immediately on a project that combined both energy access and climate change, with our second major project in Liberia. While the negotiations were still underway in Paris, a team of reporters from the Huffington Post was in Liberia filming APL putting those ideas into action.

The remote village of Kwendin, Liberia, had almost no electricity at all. But under a project sponsored by the USAID Power Africa program, three PP2O Power Pallets are being installed to provide power to every home in the community, as well as street lights, small businesses, and more. It’s more than just lighting–it’s energy for productive use that allows putting value adding tools like sewing machines and saws to work, creating jobs and opportunities for people in Kwendin.

Below are some screenshots from the excellent news piece they produced — we encourage you to click and watch. They did a very good job explaining the need for energy access in Africa, and what the solution means for local lives.

What lies ahead in 2016 for APL
This year we’ll be releasing our beta version of the 15OkW Powertainer, funded under a grant from the state of California to help reduce wildfire risk. We’ll also be releasing new versions and upgrades for our Power Pallets, making them easier to use, more powerful and more reliable.  And we’ll be working to implement the new incentive and funding programs following the COP21 agreement, which will help grow projects for all of us. We’ll be sharing details on those soon.

In rural areas of the US? Quick turn around grants available from USDA
For those of you in rural areas in he US, know there is grant funding available from the USDA for projects in the US to create renewable energy in remote communities. The Renewable Energy Systems and Energy Efficiency Improvement Assistance program provides grants and guaranteed loans to agricultural producers and rural small businesses to purchase and install renewable energy systems and make energy efficiency improvements to their operations. It has a short turn around, so give it a quick look.

Thanks for your interest and support of our work, and very best wishes in this New Year.
