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. There were notable installation restrictions for the TEG unit, and the gas temperature at the exhaust inlet pipe could not reach the target value.

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

Green Car Congress

Supercritical carbon dioxide is a non-toxic, stable material that is under so much pressure it acts like both a liquid and a gas. This carbon dioxide, which stays within the system and is not released as a greenhouse gas, can get much hotter than steam—1,290 degrees Fahrenheit or 700 Celsius.

New highly efficient catalyst for photoelectrochemical CO2 reduction toward methane

Green Car Congress

Thirty percent of the energy in the US comes from natural gas. In practice, the artificial photosynthesis panel would need to be connected to a source of concentrated carbon dioxide—for example, carbon dioxide captured from industrial smokestacks. If we can generate green methane, it’s a big deal.

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

Green Car Congress

During 2022 and early 2023, electrolysis, CO 2 capture, and synthesis units located in sea containers will be connected to each other and VTT Bioruukki research infrastructure. The work has started by first modifications to the research infrastructure at VTT Bioruukki. The E-fuel project pilot runs are expected to be completed during 2023.

million) into another phase of their research on CO2 scrubbing for carbon capture. Different scrubbing agents were initially tested in three test phases of six months each as part of the pilot operation of the CO2 scrubbing plant connected to the Niederaussem lignite-fired power plant to finally identify an optimum solvent developed by BASF.

Soletair demo plant produces renewable hydrocarbon fuel from CO2 captured from the air

Green Car Congress

The system produces high-purity hydrogen gas at elevated pressures. The hydrogen gas can also be used as a chemical energy storage and can later be reconverted into electricity in a fuel cell, albeit with an additional penalty in terms of losses in conversion. The produced dry hydrogen gas is stored into two 350 l composite cylinders.
