Power, heat, controls and complete systems.
Explore our hot air turbines, steam systems, controls, test beds and BIOCCUS system capability.
Hot air turbines
Bluebox-50 to Bluebox-330 (50 to 330kWe) — electricity from flue gas with 450 °C clean air still available for the process.
View turbinesSteam systems
Steam plant where the site needs it — designed alongside turbines or as a stand-alone package.
OpenControl systems
Plant controls and power electronics using Siemens S7 software, backed by in-house expertise.
OpenTest beds
Design and supply for 50–1,000 kW high-speed machines, including loads, controls and frames.
OpenBIOCCUS systems
Integrated heat, power, biochar and carbon-capture systems developed with Ricardo and Woodtek.
OpenHot air turbines
Four machines. One architecture.
Electricity from waste heat — without throwing the heat away. Bluebox hot air turbines discharge air at 450 °C, so the remaining energy can still dry grain, raise steam, pre-heat industrial combustion air, feed a district heating network or drive a second power cycle.
Compress air, take heat from flue gas, make electricity, leaving 450 °C clean air for the process. Datasheets on request.
