New highly efficient catalyst for photoelectrochemical CO2 reduction toward methane

Green Car Congress

The work, presented in a paper in Proceedings of the National Academy of Sciences (PNAS), offers a unique, highly efficient, and inexpensive route for solar fuels synthesis. The solar-powered catalyst is made from abundant materials and works in a configuration that could be mass-produced. 1 under air mass 1.5 —Zhou et al.

Panasonic develops highly efficient artificial photosynthesis system with gallium nitride semiconductor for conversion of CO2 to formic acid

Green Car Congress

Panasonic has developed an artificial photosynthesis system using a gallium nitride photoelectrode and a metal catalyst which uses sunlight to convert CO 2 mainly to formic acid (an important intermediate in chemical synthesis) at an efficiency (solar energy to chemical energy) of 0.2%—a —a comparable level to that of plants.

Audi aims to reduce CO2 emissions by 30% over the vehicle lifecycle by 2025

Green Car Congress

In the long term, Audi is pursuing the vision of CO2-neutral mobility and aims to be climate-neutral throughout the company on balance by 2050. Before the end of this year, Audi will also present the Audi e-tron Sportback, another derivative of the series. The solar-energy park will produce more than 9.5 Earlier post.).

New inexpensive catalyst for conversion of CO2 to CO could help with storage of renewable energy

Green Car Congress

Storage of solar and other sources of renewable electricity may be enabled by the catalytic production of fuels such as H 2 or reduced carbon-containing compounds via the electro-chemical reduction of H 2 O or CO 2 , respectively. At present, the importance of the Bi 3+ ions to the efficacy of Bi-CMEC is unclear.

New plasma synthesis process for one-step conversion of CO2 and methane into higher value fuel and chemicals

Green Car Congress

Instead of using H 2 , direct conversion of CO 2 with CH 4 (dry reforming of methane, DRM) to liquid fuels and chemicals (e.g. CO 2 and CH 4 ) present and produce a variety of chemically reactive species including radicals, excited atoms, molecules and ions.
