PP30 25 kW Power Pallet

PP30 25 kW Power Pallet

Our flagship product currently available for order and delivery. The Power Pallet is a complete biomass power generation solution that converts woody biomass into electricity.  It is a compact and fully automated system–from biomass in–to electricity out–delivered at a price point of $2 per watt equipment cost.

The Power Pallet PP30 is our most recent version of the Power Pallet biomass genset, with many enhancements and improvements from the prior Power Pallet PP20. It comes standard with grid-tie electronics for taking advantage of applications such as microgrids, feed-in tariffs, and net energy metering, as well as heat exchangers for heating water for combined heat and power (CHP) applications. The PP30 is also much quieter; the engine is now enclosed, and the cooling fans are low-noise electric fans that only turn on as the engine coolant needs cooling, such as when it is not being used to heat water. Power output has increased nearly 50% over the PP20, and the session runtime has been extended as well.

Why it’s different The Power Pallet is distinguished among biomass power generation systems by its compact size and affordable price. Its integration of CHP capabilities with power generation and woody biomass disposal make it a perfect candidate for applications which find value in heat, electricity, and wood or nutshell disposal.

For the specifications of the machine, including the heat output of the CHP system, see the PP30 spec sheet.

The PP30 is now available for pre-sales to qualified buyers.

Please read over the Basic User Considerations to see if the PP30 is a good fit for your biomass power application.


50 kW Power Pallet 30 Container System

The 50 kWe Power Pallet 30 Container System uses our two of our PP30 for a complete biomass power generation solution that converts woody biomass into electricity. The BASE version is basically two PP30s units housed within a standard 20 foot shipping container envelope. It will provide twice the power and heat capacity of a single Power Pallet PP30 to up to 50 kW and 100 kWth peak capacity. 


130 kW Power Pallet Hybrid Biomass Microgrid

The 130 kWe containerized Power Pallet system also provides 100 kWth of thermal energy via the integrated CHP systems from the two PP30s. Also included is a battery storage system and inverter to allow the continuous 50 kW output of the Power Pallets to be combined with an additional 80 kW from the batteries for a combined intermittent output of 130 kWe. The HYBRID version has additional inverter-based technology with integrated storage capacity yielding up to 130kWe and 100 kWth of peak capacity. This HYBRID unit opens up additional use cases where short spikes of energy are needed (e.g motor start up) while also providing a more standard distributed energy resource that can be added to existing microgrids with minimal complication.


CharTainer

The ALL Power Labs CharTainer is a compact, high-volume, Combined Heat and Biochar (CHAB) pyrolizer system enclosed within a standard 20-foot shipping container. The system is fully automated and complete – from biomass hopper, gasifier-retort, and clean-burning flare with heat exchangers to biochar takeoff – all integrated within the shipping container envelope. The CharTainer uses a scaled-up version of APL’s newest Swirl Hearth architecture previously refined and proven in our PT150 PowerTainer.  The swirl hearth architecture includes technology innovation that widens the range of acceptable feedstock and ensures the quality of biochar produced. The CharTainer is being developed to meet the ever-increasing demands for localized biomass waste disposal as well as high-quality, high-temperature, electrically active biochar in the agronomy and climate/carbon mitigation sectors. Partnering with our carbon-drawdown initiative, The Local Carbon Network, APL’s engineers have been working with biologists, agronomists, farmers, and climate researchers to perfect biochar-retort technology and biochar application techniques. One result of this work is the design of the Pilot CharTainer, capable of a 250 kgs-of-biomass-per-hour throughput delivering up to 50 kilograms per hour of the highest quality, tar-free, geo-conducting biochar available.


PP20 Power Pallet – DISCONTINUED

We no longer produce the PP20 version of the Power Pallet. See this page for our new PP30 Power Pallet. 

A complete biomass power generation solution that converts dense biomass like wood chips and nut shells into electricity and heat.  It is a compact, integrated system – from biomass in, to power out – delivered at the newly reduced price under $1.50/Watt.

The Power Pallet is comprised of the GEK Hot TOTTI multi-stage gasifier, spark fired industrial engine, generator head, and electronic controller. The system automatically adjusts syngas/air mixture via a wide band Bosch oxygen sensor, shakes the grate when needed, and removes ash via a mechanical auger. The Process Control Unit (PCU) monitors and responds to all internal reactor, filter and engine conditions, displaying the results on an LCD screen.


Feedstocks:

We are always looking for ways to increase the types of feedstocks compatible with our gasifiers. If you have access and are interested in using a feedstock that is not listed below or has not been currently validated, please contact us to review your options. CLICK HERE to view our handbook document which includes more information about feedstock compatibility.

Currently these are the only approved and validated feedstocks:

  • Nutshells, e.g. Walnut, Hazelnut (other varieties may require additional testing)
  • Woodchips, e.g. Pine, Oak

These feedstocks cannot be used in our equipment, and any use will automatically void your warranty.

  • Municipal Solid Waste (MSW)
  • Household Solid Waste (plastics, kitchen waste, etc.)
  • Chicken litter, and manure of any kind
  • Sugar cane bagasse (not even the pellets)
  • Shredded Tires, plastics of any kind
  • Mushroom growth media (which usually contains manure and saw dust)

These feedstocks also cannot be used, but specialized preparation and blending techniques might be able to be developed to allow some limited use following validation by APL-authorized testing.

  • Wood pellets and briquettes
  • Saw dust
  • Rice husk, rice straw, wheat husk, wheat straw
  • Miscanthus, Switchgrass
  • Hemp canes and byproducts
  • Coconut husk (coconut shells work well, just not the husk)
  • Olive Pomace, Olive Pits
  • Date Pits, Palm fronds or empty fruit palm fruit bunches

Accessories and Recommended Equipment

Optional Accessory: Continuous Feed Hopper System

To eliminate manual refilling of the hopper, ALL Power Labs is now offering a Continuous Feed Airlock as an option on all Power Pallets. Controlled by an Electronic Control Unit (ECU) with an array of sensors, this system allows a store of feedstock at ground level to be automatically fed, via a standard agricultural feed transport (not included), into the hopper through an automated gate valve on the hopper lid. The horizontal motion of the linear drive operating the gate valve is converted into a vertical sealing force by an innovative leaf spring system, ensuring an airtight seal and reliable operation.

The custom ECU, using an open-source processor with an APL -designed circuit board, reads data from sensors installed in the hopper and opens the gate valve when the feedstock is low, then signals the motorized feed transport to reload the hopper. Once it detects the hopper is full, the ECU shuts off the feed transport then closes the gate valve. This smart automation also reads gate position and motor-current sensors to assure safe operation for both operators and the Power Pallet. If problems are detected, the ECU will set the Continuous Feed system into various safe and stable modes and trigger alarms to alert the operator


Here are few third party tools to help realize all the potential of your gasifier system. We know of these from experience with some of our existing installations.

DR 11.5 Horsepower Chipper
Lumeter microgrid meters
The same DR 11.5 horsepower chipper in use every week on our project in Liberia. It’s affordable and makes wood chips that are just the right size for the GEK.Microgrid? You’re going to need a metering system. These meters from Lumeter, in use on our project in Haiti, offer easy set up via simple remote controls.
