Toyota and DIFFER partner on direct solar production of hydrogen from humid air, rather than water

Green Car Congress

The Dutch Institute for Fundamental Energy Research ( DIFFER ) is partnering with Toyota Motor Europe (TME) to develop a device that absorbs water vapor, and splits it into hydrogen and oxygen directly using solar energy. Working with gas instead of liquid has several advantages. —Mihalis Tsampas.

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.

KU Leuven team creates solar panel that produces hydrogen from moisture in air

Green Car Congress

Bioscience engineers at KU Leuven have created a solar panel that produces hydrogen gas from moisture in the air. Twenty of these solar panels could provide electricity and heat for one family for an entire winter. A traditional solar panel converts between 18 to 20% of the solar energy into electricity.
