Researchers use chemical looping process to produce hydrogen from hydrogen sulfide gas

Green Car Congress

Researchers at The Ohio State University have used a chemical looping process to produce hydrogen from hydrogen sulfide gas—commonly called “sewer gas”. The process is detailed in a paper in the journal ACS Sustainable Chemical Engineering. —Jangam et al. —Kalyani Jangam, lead author. 1c03410.

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.

Gold Hydrogen Program coalition launches program for subsurface biomanufacturing of hydrogen

Green Car Congress

The Gold Hydrogen Program , a coalition of organizations seeking to support the scale of this clean energy resource, announced its launch and the debut of a pilot microbial Gold Hydrogen Process. Found naturally deep in the Earth, “gold hydrogen” is a resource that is produced biologically and in the subsurface.

million) ammonia cracker prototype designed to produce green hydrogen at industrial scale. The prototype will use ammonia to deliver 200kg of hydrogen a day—enough to power around 5-10 hydrogen fuel cell-electric buses. Ammonia has a high hydrogen density and is readily transportable in bulk. million (US$4.24

Infrastructure bill's coal-sourced "blue" hydrogen worse than combustion, study suggests

Green Car Reports

The Congressional bipartisan infrastructure bill includes a proposal for hydrogen-production hubs that could use coal as an energy source. But even such allegedly clean hydrogen could produce high levels of greenhouse-gas emissions, according to a new study published in the journal Energy Science & Engineering.

8 Rivers announces 8RH2 CO2 Convective Reformer for ultra-low carbon hydrogen production from natural gas

Green Car Congress

8 Rivers Capital announced the development of the 8RH2 CO 2 Convective Reformer—a technology for the production of ultra-low carbon hydrogen from natural gas. The 8RH2 technology has been invented by Rodney Allam MBE, a chemical engineer from Bath in the UK, who also pioneered the Allam-Fetvedt-Cycle (AFC) cycle.
