Green Hydrogen ABC

Green hydrogen has been billed as the latest answer to curbing carbon emissions. So, what exactly is it and how can Australia harness it as a mainstream energy source?

"We find the most significant sensitivity stems from the electrolyser turndown and the commensurate need to buffer solar electricity with storage or grid electricity."

Perhaps solar will not be the best path to "Green Hydrogen" but we can likely address intermittency here in Australia: We could have a combination of solar-pumped hydro Turkey Nest, Gravity Mines, or even more interesting Geothermal/ hot dry rocks system with a HEWI?

Breakthrough Technology?
 

"The new catalyst splits seawater and generates hydrogen extremely efficiently in the lab, resisting corrosion and avoiding chlorine production. The research team says it'll be easy to manufacture at scale, and should be cheap enough at commercial scale to help green hydrogen compete with fossil fuels RMIT"

Green hydrogen can't be viewed as environmentally friendly if it drinks huge amounts of fresh water, or results in the bulk output of toxic chlorine, according to RMIT researchers who say they've come up with a cheap technique that does neither.

"To be truly sustainable," says Mahmood, "the hydrogen we use must be 100% carbon-free across the entire production life cycle and must not cut into the world’s precious freshwater reserves. Our method to produce hydrogen straight from seawater is simple, scaleable and far more cost-effective than any green hydrogen approach currently in the market. With further development, we hope this could advance the establishment of a thriving green hydrogen industry in Australia."
