Power Pallet

The New Updated PP30 Power Pallet

he PP30 is the latest generation of the Power Pallet biomass gasifier genset system. It represents the largest upgrade of the capabilities and convenience of the Power Pallet up to this point. The PP30 features:

  • Larger, more efficient engine and more efficient generator, which increases the power output to 25kW, vs. the 18kW of the PP20.
  • Standard feature CHP water heating capability, utilizing three stages of waste heat recovery to produce up to 2kW of thermal output per 1kW of electrical load
  • Standard feature grid-tie hardware, enabling all PP30s to integrate into a microgrid with existing power sources or the main grid.
  • Simplified filtration architecture which eliminates the need to sift and prepare charcoal filter media while also eliminating the regular maintenance task of purging the engine.
  • Stainless-steel enclosure and a selectively activated electric cooling fan system to reduce noise.
  • Conical jam-resistant hopper to reduce risk of feedstock jams.
  • Larger ash collector vessel and cyclone dust can.
  • New high efficiency genheads configurable to three phase, at 190-240 / 380-480 V Phase-Phase, 60 Hz or 50 Hz.

Why it’s different

See PP30 vs PP20 Comparison Sheet Here

The PP30 Power Pallet is the culmination of our long work to create an expertly engineered, small-scale gasification solution that is realistic for today’s user. While personal scale gasification has long held tremendous promise, the realities of making it work usually prove too much for regular mortals. The high bar of operator expertise and extreme sensitivity to fuel particulars usually combine to make what seems simple in principle, exceedingly difficult in practice.

The Power Pallet has significantly widened this window for success by embedding the needed operator expertise in an onboard electronic brain. These smarts are further extended by a multi-stage gasification architecture and an innovative waste heat capture and recycling system – what we call the Tower of Total Thermal Integration (TOTTI). In traditional systems, hot engine exhaust and hot output wood gas have been problems requiring extra space and cooling components to counter. With the GEK TOTTI, we’ve transformed this waste energy into useful new inputs to the gasification process.  It’s like adding a new free heat source to fix the old and well known thermal challenges of a gasifier.

This Gasifier-Engine thermal integration significantly improves tar conversion, fuel flexibility and general efficiency of the gasifier-engine system. It enables the Power Pallet to solve the tar issue in the reactor, rather than in a large downstream filtering system, significantly reducing the cost, complexity and installation footprint in the process.

Engine and Genhead

The PP30 uses an advanced 4.0 liter 4 cylinder Ashok Leyland engine, spark-fired, but based on their heavy-duty diesel industrial engine.

The engine is mated to a Marathon genhead with automatic voltage frequency and 3x rated amperage at surge for high machinery start capacity.  The genhead is 12 wire so they can be configured to single, split or three phase, in wye or delta configuration and supports all common global voltages: 120, 208, 240 and 400V AC, at either 50 hz or 60 hz.

Actual power produced is highly dependent on the fuel shape, size and moisture content.  Solid biomass is not the consistent fuel source like we assume with diesel or gasoline.  We have used “25 kW” rating although maximum power at 60 Hz is actually somewhat higher.


ALL Power Labs provides extensive customer support before and after a sale, online and in person, to help you get your project up and running. This includes:

  • The Power Pallet product documentation
  • Pre-sales consulting available by contacting us through our contact page
  • On-site commissioning and training for a nominal fee

Please review the PP30 Basic Considerations to qualify your use case.

PP30 Operation Manual is available on the Support Page.

Note that the Technician’s Handbook available there is based on the PP20, and is currently being updated to include PP30 specifics, although many features are unchanged or similar.

The Pilot version of the CharPallet will be available to a limited number of customers starting in early 2024. We expect to have units available to retail customers towards the end of 2024
The CharPallet will be released in pilot programs in California in 2024. Other regions to follow soon after.
We expect the base system to be less than $30,000 and a more fully featured and instrumented research version to be available for less than $40,000.

The CharPallet is an excellent tool for academic institutions working in R&D or education in the biochar and renewable energy spaces.
• Users with biomass waste streams can use the equipment for on-site disposal to minimize waste disposal logistics and costs.
• Small agricultural producers and gardeners can turn their woody waste into a value-added product that can be sold, traded, or used as a key ingredient in restorative soil amendments, minimizing their carbon footprints while adding reputational value to their products.

Please review this Appropriate Feedstock link. However, ongoing testing and refinement of our novel tar-cracking Swirl Hearth reactor architecture indicates greatly expanded compatibility with a wider range of feedstocks. So far we have confirmed its ability to handle much finer biomass particles: ~0.125 in. (~3mm), than our previous reactors.

The quality of the biochar produced is highly conductive with extremely low tar/PAH content. Please review these Skycarbon Specifications which show biochar qualities and certifications for walnut feedstock. We have been recording similar results with for other feedstocks.

The emissions are kept very low through a sophisticated cyclonic combustor with real-time NOx feedback for mixture optimization. Third-party emissions testing to EPA standards is in process. We will continue to share results with potential customers.

The CharPallet is planned to be a Combined Heat and Biochar (CHAB) production reactor with a biochar output of 5kg/hr compared to the PP30’s 2kg/hr. It can be configured to provide 50kWth heat output, similar to the PP30 but without electrical power output and at roughly half the footprint and price, and one quarter the weight of the PP30.

Yes it can, but fueling an IC genset with the CharPallet’s syngas output requires a number of additional components and considerations. APL can provide engineering services for suitable use cases. Feel free to contact us for help.
