Hot Air Turbines
Low impact power stations fueled with biomass or waste
Page last modified
April 11 2024
Revolutionising the decarbonised distributed generation market by supporting smaller-scale, low impact power stations fuelled with biomass or waste to provide power and heat to our homes and places of work.
How it works:
- Fresh air is pressurised
- The pressurised air is heated in a heat exchanger
- Air depressurises and cools first through the “turbocompressor” needed to pressurise the air in the first place
- Air depressurises and cools more in a “Power Turbine” to produce electricity
There are multiple sources to heat the air:
- Waste wood/biomass
- Municipal waste combustion
- Pyrolysis gas from biochar production
- Flare gas (HX not required)
