The Full Solution: the 20kw Power Pallet

The Power Pallet is 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 breakthrough price of $1-$2/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.

Power Pallets are available in a 20kw size, using GM industrial engines. Genheads are configurable to single, split or three phase, at 120/208/240Vac, 60hz or 50hz.  We also offer an optional grid-tie package, bundled with onsite set up.


 

Why it’s different

The Power Pallet is the culmination of our long-standing project 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 “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 these “wastes” 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.

The result is a compact and technically advanced solution. It is a solution that can deliver the largely hands-off, untended operation we expect from contemporary power generation equipment.  And given its minimized component architecture, we can also deliver it an unprecedented price point that makes ROI sense without subsidies or other artificial financial supports.

Engine and Genhead Options 

The Power Pallet uses a GM 4cyl 3.0 liter spark fired engine.  Both of these engines are extreme longevity, all cast iron industrial engines, optimized for dry gaseous fuels.  They both have long track records of exceeding 10,000 hours of run life.  Actual longevity of the engine is, as always, highly dependent on your maintenance schedule.

Either engine option is mated to a Mecc alte genhead of related size.  These genheads have automatic voltage frequency and 3x rated amperage at surge for high machinery start capacity.  The genheads are 12 wire so they can be configured to single, split or three phase, in wye or delta configuration.  They support all common global voltages, 120, 208, 240 and 400 vac, at either 50hz or 60hz.

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 “10kw” and “20kw” to represent the peak power production capacity; average maximum constant output will be somewhat less: 17kW/hour at 50 Hz and 15kW/hour at 60 Hz.
