Cambridge researchers develop standalone device that makes formic acid from sunlight, CO2 and water

Green Car Congress

Researchers at the University of Cambridge, with colleagues at the University of Tokyo, have developed a standalone device that converts sunlight, carbon dioxide and water into formic acid, a carbon-neutral fuel, without requiring any additional components or electricity. —senior author Professor Erwin Reisner.

AirCapture, OCOchem and partners win $2.93M DOE grant for direct air capture of CO2 and conversion to formic acid

Green Car Congress

Carbon dioxide capture company AirCapture and carbon dioxide conversion company OCOchem, along with other partners, have won a $2.93-million OCOchem transforms recycled CO 2 , water and zero-carbon electricity to produce formic acid, a globally traded commodity chemical and emerging electro-fuel.

PNNL team develops new low-cost method to convert captured CO2 to methane

Green Car Congress

By using a water-lean post-combustion capture solvent, (N-(2-ethoxyethyl)-3-morpholinopropan-1-amine) (2-EEMPA), they achieved a greater than 90% conversion of captured CO 2 to hydrocarbons—mostly methane—in the presence of a heterogenous Ru catalyst under relatively mild reaction conditions (170 °C and 2 pressure).

Evonik and Siemens Energy commission pilot plant for conversion of CO2 to chemicals

Green Car Congress

Evonik and Siemens Energy commissioned a pilot plant—sponsored by the German Federal Ministry of Education and Research (BMBF)—that uses carbon dioxide and water to produce chemicals. It consists of a CO electrolyzer, developed by Siemens Energy, a water electrolyzer and the bioreactor with Evonik’s know-how.

Surrey team developing direct-air-capture CO2 to methanol process

Green Car Congress

Pulling chemical building blocks directly out of the air can create a just-in-time process that will help us finally say goodbye to safety hazards such as storing large quantities of chemicals. Importantly, this process could boost the economy by spurring carbon-negative growth, as well as provide fuel security for the UK. —Dr Duyar.

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

Green Car Congress

Because so much energy is lost turning steam back into water in the Rankine cycle, at most a third of the power in the steam can be converted into electricity. In comparison, the Brayton cycle has a theoretical conversion efficiency upwards of 50%. The recuperator improves the overall efficiency of the system.

UC Santa Barbara team develops catalytic molten metals for direct conversion of methane to hydrogen without forming CO2

Green Car Congress

The insoluble carbon floats to the surface of the melt, where it can be removed and stored or incorporated into composite materials. Bi 0.73 ) achieved 95% methane conversion at 1065°C in a 1.1-meter Bi 0.73 ) achieved 95% methane conversion at 1065°C in a 1.1-meter Under these conditions, the equilibrium conversion is 98%.
