World’s highest-efficiency hydrogen system scales up for mass production

Posted on by

Hysata claims its capillary-feed electrolyzer is the world's most efficient, using some 20% less energy to produce hydrogen while also being cheaper to install and maintain

You have to throw some energy away to make hydrogen – typically around 20-30%, even with the best systems, which use around 52.5 kWh of energy to create a kilogram of hydrogen that can store 39.4 kWh of energy. It’s a waste of renewable energy, and it contributes to the high cost of a green fuel option that’s really struggling to compete against fossils and batteries in many applications.

Trillions of tons of buried hydrogen: Clean energy gold rush begins

Posted on by

There’s enough natural hydrogen trapped underground to meet all projected demands for hundreds of years. An unpublished report by the US Geological Survey identifies it as a new primary resource, and fires the starter pistol on a new gold rush.Continue… Continue reading Trillions of tons of buried hydrogen: Clean energy gold rush begins→

Ultra-high density hydrogen storage holds twice as much as liquid H2

Posted on by

A nanoporous material that holds hydrogen at twice the density of cryogenic liquid H2 could address the challenges of large-scale liquid and gas storage that have held this clean fuel back.Continue ReadingCategory: Energy, ScienceTags: Hydrogen, Hydrog… Continue reading Ultra-high density hydrogen storage holds twice as much as liquid H2→

Cryo-compressed hydrogen: A 40% aircraft range boost over liquid H2

Posted on by

ZeroAvia is working with San Francisco startup Verne to bring an even more energy-dense form of hydrogen to the clean aviation space. Cryo-compressed H2 could reduce costs, speed up fueling, and unlock 40% more flight range than cryogenic liquid H2.Con… Continue reading Cryo-compressed hydrogen: A 40% aircraft range boost over liquid H2→

World’s first liquid-hydrogen eVTOL aircraft promises 1,150-mile range

Posted on by

The Sirius Jet will fly up to 1,150 miles (1,851 km) at speeds up to 323 mph (520 km/h) on a clean liquid-hydrogen powertrain. It’ll rise vertically off a pad thanks to a deflected vectored thrust system using 20 smallish electric ducted fans.Continue … Continue reading World’s first liquid-hydrogen eVTOL aircraft promises 1,150-mile range→

Kawasaki has built a hydrogen-powered, supercharged Ninja H2 SX

Posted on by

Kawasaki is doing some fascinating work toward decarbonizing motorcycles. After launching the world’s first hybrid streetbike in the Ninja 7 Hybrid, it’s now built a supercharged, zero-emissions, hydrogen-powered Ninja H2 SX. An H2 H2, if you will.Cont… Continue reading Kawasaki has built a hydrogen-powered, supercharged Ninja H2 SX→

“Swiss army knife” of life and energy buffet found on Saturnian moon

Posted on by

The most promising places to look for life beyond Earth might not be Mars but icy moons orbiting gas giants. Saturn’s moon Enceladus has just climbed the list, as NASA data reveals it’s home to a molecule thought to be key to the origin of life, and su… Continue reading “Swiss army knife” of life and energy buffet found on Saturnian moon→
