PGPS Benefits for Power Generation

Until now, portable and backup power applications under 50 kW often resort to diesel, gasoline, or propane generators despite their damaging emissions because cleaner engines did not yet achieve portable scale nor competitive value. The Portable Green Power System (PGPS) is a <300-pound power generator positioned to decarbonize the electricity sector as both a temporary and backup power generation solution for utility companies with its 45 kW zero carbon operation, superior portability, scalability, and price parity per kW with fossil-fueled alternatives.

Unmatched Portability: Compared to existing engines of similar power, the PGPS is 90% smaller and lighter per kW and can be easily transported without specialized equipment.

Multi-fuel: The PGPS accepts hydrogen for zero carbon operation, biofuel and synthetic gas for carbon neutral operation, as well as natural gas, gasoline, diesel, and jet fuel for emergency power applications.

Distributed, Scaled Power: Multiple PGPS units can be stacked to generate 90/135/180+ kilowatts of electricity as needed, and a single PGPS can operate at lower speeds for applications less than 45 kW for improved endurance.

Low Cost through 3D Printing: The PGPS leverages metal additive manufacturing to not only achieve unprecedented portability in a gas turbine engine, but also a compelling and disruptive price point for cleaner portable power generation.
