experts are predicting that the biggest obstacle to bringing green hydrogen to market--its capital cost--is about to come down. “Everybody is predicting that the cost curve will come down, just as it has with solar and wind power,” Recharge News wrote last month. The article titled “Why green hydrogen is key to the global energy transition” continues: “Though, to get the price point right, you have to reach economies of scale. Then it’s just a matter of when the industry is primed to take the next step.” involvement from major players like Royal Dutch Shell is already getting us closer to that threshold.
And now, we may be even closer thanks to a breakthrough this month by a group of Japanese scientists from the Tokyo University of Science, who have managed to efficiently produce green hydrogen in a novel way
...
“the set-up uses just a few basic ingredients - light from a mercury-xenon lamp, a solution of water and methanol, and a particular type of rust (or iron oxide) called α-FeOOH.” In the lab, this combination was a smashing success, with a hydrogen yield 25 times greater than existing methods that use titanium dioxide catalysts.
“One of the biggest challenges in hydrogen fuel production is teasing hydrogen atoms apart from other molecules, and keeping them that way without the entire thing blowing up,” the Science Alert article continues. “In the new method, by swapping titanium with rust, the hydrogen gas generated seemed to be blocked from recoupling with oxygen, making the separation of the elements easier, and reducing the risk of explosion at the same time.”
This cheap, stable catalyst combo could be the winning ticket to get green hydrogen to market. If so, this would have seriously positive implications for some of our dirtier industries, and any reduction in emissions is a very good thing on the eve of peak oil and catastrophic climate change.
