Monash study on solar-driven electrolysis for green hydrogen production cautions on life-cycle emissions and EROI

Green Car Congress

Researchers at Monash University in Australia have conducted a lifecycle analysis and net energy analysis (LCA/NEA) of a hypothetical large-scale solar-electrolysis plant for the production of green hydrogen. of hydrogen is currently produced via water electrolysis and only a fraction of this production is powered by renewable energy.

Researchers develop new stable artificial photosynthesis device to produce ethylene and hydrogen from sunlight and CO2

Green Car Congress

A research team has developed a new artificial photosynthesis device component with remarkable stability and longevity as it selectively converts sunlight and carbon dioxide into two promising sources of renewable fuels: ethylene and hydrogen. We knew it was unstable—but we were surprised to learn just how unstable it really is.

Solar-to-Jet-Fuel System Readies for Take-Off

Cars That Think

A glimmer of hope, however, comes from solar fuels. For the first time, scientists and engineers at the Swiss Federal Institute of Technology (ETH) in Zurich have reported a successful demonstration of an integrated fuel production plant for solar kerosene. Finally, the syngas is processed to kerosene in the gas-to-liquid unit.

Monash “artificial photosynthesis” system achieves in excess of 22% efficiency for production of hydrogen from water

Green Car Congress

A team at Monash University (Australia) has developed an “artificial photosynthesis” system that delivers the highest efficiency reported to date—in excess of 22%—for the solar-driven conversion of water to hydrogen. A paper on the researchers’s work is published in the RSC journal Energy & Environmental Science.

MITEI study finds hydrogen-generated electricity is a cost-competitive candidate for backing up wind and solar

Green Car Congress

A team at MITEI (MIT Energy Initiative) has found that hydrogen-generated electricity can be a cost-competitive option for backing up wind and solar. As we move to more and more renewable penetration, this intermittency will make a greater impact on the electric power system. —Drake Hernandez.

Berkeley Lab researchers advance hybrid bioinorganic approach to solar-to~chemicals conversion; 50% electrical-to-chemical, 10% solar-to-chemical efficiencies

Green Car Congress

A team of researchers at the US Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have hit a new milestone in their development of a hybrid bioinorganic system for solar-to-chemical energy conversion. In the new system, solar energy is used to split the water molecule into molecular oxygen and hydrogen.
