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.

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.

BMW Group sourcing aluminum produced using solar energy from EGA

Green Car Congress

The BMW Group will begin sourcing aluminum produced using solar electricity with immediate effect. Generating the electricity needed to produce primary aluminum, i.e. aluminum obtained directly from the mineral compound alumina, is alone responsible for about 60% of the global aluminum industry’s greenhouse gas emissions.
