Photocatalytic optical fibers convert water into hydrogen

Green Car Congress

Researchers at the University of Southampton have transformed optical fibers into photocatalytic microreactors that convert water into hydrogen fuel using solar energy. Alongside hydrogen generation from water, the multi-disciplinary research team is investigating photochemical conversion of carbon dioxide into synthetic fuel.

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 Hiroshi Hashiba et al.

Researchers develop Na-ion direct formate fuel cell for co-production of electricity and hydrogen

Green Car Congress

Using formate—a solar fuel that can be readily synthetized from carbon dioxide—the researchers reported that a proof-of-concept e-h 2 Na-DFFC yielded a peak power density as high as 168 mW cm ? A paper on their work is published in the Journal of Power Sources. 2 and 35 hours of stable operation at room temperature.

Swiss team develops effective and low-cost solar water-splitting device; 14.2% solar-to-hydrogen efficiency

Green Car Congress

The prototype system is made up of three interconnected, new-generation, crystalline silicon solar cells attached to an electrolysis system that does not rely on rare metals. crystalline Silicon (c-Si) solar cells show high solar-to-electricity efficiencies, and have demonstrated stabilities in excess of 25 years.

Bauhaus Luftfahrt analysis finds solar thermochemical jet fuel production viable only if CO2 captured from renewable sources and not flue gases

Green Car Congress

A team from Bauhaus Luftfahrt in Germany has analyzed the climate impact and economic performance of solar thermochemical jet fuel production. Schematic of solar thermochemical fuel production path. The syngas is stored and finally converted into jet fuel via the FT process. Thermochemical conversion efficiency is 20%.
