Sergey Brin’s secretive airship company LTA Research and Exploration is planning to power a huge disaster relief airship with an equally record-breaking hydrogen fuel cell. From a report: A job listing from the company, which is based in Mountain View, California and Akron, Ohio, reveals that LTA wants to configure a 1.5-megawatt hydrogen propulsion system for an airship to deliver humanitarian…

A hydrogen fuel revolution is coming – here’s why we might not want it
Hydrogen is widely touted as a green fuel for everything from cars and planes to heating homes. But all too often it has a dirty secret Source: https://www.newscientist.com/article/mg24933200-400-a-hydrogen-fuel-revolution-is-coming-heres-why-we-might-not-want-it/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Are Hydrogen Fuel Cell Vehicles the Future of Autos?
Long-time Slashdot reader schwit1 shared this article from ABC News: What if your electric vehicle could be refueled in less than 5 minutes? No plug, no outlet required. The range anxiety that’s stymied sales of EVs? Forget about it. Three EVs can meet these demands and allay concerns about owning an emissions-free vehicle. There’s just one drawback. You can only find…

Hydrogen-Powered Train Makes Its First Trip in the UK
“Trials of a hydrogen-powered train are underway in the U.K.,” reports CNBC:
The HydroFLEX train — which has been developed by a team from the University of Birmingham and Porterbrook, a rolling stock firm — uses a fuel-cell which combines hydrogen and oxygen to generate electricity, heat and water… It’s hoped that the technology will be available to retrofit trains already in…
Hydrogen-Powered Passenger Plane Completes Maiden Flight In ‘World First’
ZeroAvia’s hydrogen fuel-cell plane that’s capable of carrying six passengers completed its maiden flight this week. The aircraft has been retrofitted with a device that combines hydrogen and oxygen to produce electricity. CNBC reports: ZeroAvia has said the trip, described as a “hydrogen fuel cell powered flight of a commercial-grade aircraft,” is a “world first.” Other examples of hydrogen-fuel cell planes…
How planetary nebulae get their shapes
About 7.5 billion years from now, our sun will have converted most of its hydrogen fuel into helium through fusion, and then burned most of that helium into carbon and oxygen. It will have swollen to a size large enough to fill the solar system nearly to the current orbit of Mars, and lost almost half of its mass in winds….
Nikola Admits Prototype Was Rolling Downhill In Promo Video
In late 2016, Nikola Motor Company founder Trevor Milton unveiled a prototype of the Nikola One truck, claiming it “fully functions and works, which is really incredible.” A couple years later, in January 2018, the company showed the Nikola One truck moving rapidly along a two-lane desert highway. But last week, the short-selling investment firm Hindenburg Research published a bombshell report,…
Microsoft Used Hydrogen Fuel Cells To Power a Data Center For Two Days Straight
Microsoft announced Monday that hydrogen fuel cells powered a row of its datacenter servers for 48 consecutive hours, bringing the company one step closer toward its goal of becoming “carbon negative” by 2030. Engadget reports: The idea to explore hydrogen fuel cells originated in 2018, when researchers at the National Renewable Energy Laboratory in Golden, CO used a proton exchange membrane…
