CICERO-led study finds global warming effect of leaked hydrogen almost 12x stronger than CO2

Green Car Congress

A study led by Norwegian climate center CICERO has found that the global warming effect of leaked hydrogen is almost 12 times stronger than that of CO 2. Unlike exhaust from burning coal and gas that contains CO 2 , burning hydrogen emits only water vapor and oxygen. —Dr Sand The GWP100 of hydrogen.

Study finds total greenhouse gas footprint of blue hydrogen “quite high” due to fugitive methane

Green Car Congress

“Blue” hydrogen—produced through steam methane reforming (SMR) of natural gas or coal gasification, but with CO 2 capture and storage—is being described as having low or zero carbon emissions. Even if true though, the use of blue hydrogen appears difficult to justify on climate grounds. —Howarth and Jacobson.

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.

Hydrogen Opposed Piston Engine Working Group formed

Green Car Congress

Several organizations, encompassing companies, research labs, and academia, have formed the Hydrogen Opposed Piston Engine Working Group. The Working Group consists of members undertaking research and development in the field of hydrogen combustion in an opposed-piston engine. If hydrogen combustion is sufficiently lean—i.e.,

DLR: cleaner aircraft emissions reduce the climate impact of contrail cirrus

Green Car Congress

Fewer soot particles in the exhaust stream of aircraft reduces the formation of ice crystals and therefore the climate impact of the resulting contrail cirrus. The results are published in an open-access paper in the Nature Partner Journal (npj) Climate and Atmospheric Science. Burkhardt et al. —Ulrike Burkhardt.
