According to Chinese media, the electrochemical reaction of hydrogen and oxygen produces energy in a hydrogen fuel cell; the only byproduct of the reaction is water; no byproducts of nitrogen or sulfur are produced.https://interestingengineering.com/innovation/china-first-hydrogen-powered-trainI come bringing good news about hydrogenThe is a techno-optimist blog, and it's time for another techno-optimist post. By now, everyone knows about the importance of solar and wind power. Some people still argue against these technologies, but the brute logic of falling costs has simply overwhelmed the naysayers.https://noahpinion.substack.com/p/i-come-bringing-good-news-about-hydrogenUltra-light liquid hydrogen tanks promise to make jet fuel obsoleteA revolutionary cryogenic tank design promises to radically boost the range of hydrogen-powered aircraft - to the point where clean, fuel-cell airliners could fly up to four times farther than comparable planes running on today's dirty jet fuel.https://newatlas.com/aircraft/hypoint-gtl-lightweight-liquid-hydrogen-tank/Powerpaste packs clean hydrogen energy in a safe, convenient gray goopTen times the energy density of a lithium battery, in a simple magnesium-based paste that can be refilled at a pump or changed out in cartridges. Fraunhofer's Powerpaste offers a safe, convenient, high-density way to store, transport and use H2 energy.https://newatlas.com/energy/powerpaste-hydrogen-fuel-paste/?utm_source=tldrnewsletterUPDATED - New tech to produce hydrogen from tap waterA Spanish scientist has developed a system that reportedly produces hydrogen on-site without expensive electrolysis. The prototype utilizes a water tank that is initially filled with water, ferrosilicon, and sodium hydroxide.https://www.pv-magazine.com/2022/07/27/spanish-researchers-develop-tech-to-produce-hydrogen-from-tap-water2022-The Year of the Hydrogen Economy?"I've been working in hydrogen for 20 years, and this is absolutely the most exciting time, the busiest time," says Keith Wipke, manager of the Fuel Cell and Hydrogen Technologies Program at the National Renewable Energy Laboratory (NREL) in Golden, Colo. "There's just so much activity."https://spectrum.ieee.org/hydrogen-economy-inflation-reduction-actHydrogen PlaneHydrogen-powered planes take off with startup’s test flightThe plane is the largest to fly powered in part by a hydrogen fuel cell, a significant step for zero-emissions flight.https://www.technologyreview.com/2023/01/19/1067113/hydrogen-planes-test-flight/
