Yamaha and Sumitomo demo on-board thermoelectric generator for CO2 reduction

Green Car Congress

a Sumitomo Corporation Group company, jointly demonstrated a new waste heat recovery system based on a thermoelectric generator (TEG), which generates electrical power via exhaust gas heat. The main engine cooling circuit was branched and extended to TEG unit. An additional test achieved the target gas temperature.

Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

Sandia National Laboratories researchers recently delivered electricity produced by a new power-generating system to the Sandia-Kirtland Air Force Base electrical grid. The system uses heated supercritical carbon dioxide instead of steam to generate electricity and is based on a closed-loop Brayton cycle.

VTT and Neste to build integrated Power-to-Liquids demo facility; CO2 capture, green hydrogen and e-fuels production

Green Car Congress

E-fuels offer a way to expand the carbon-neutral transport fuel pool beyond biomass-based renewable fuels to replace fossil fuels in existing internal combustion engines. Power-to-Liquids technologies are on their way to commercialization in scale. The work has started by first modifications to the research infrastructure at VTT Bioruukki.
