Stainless-steel fuel lines and a series of regulators resist hydrogen embrittlement. The regulators step down H2 from 700 bar to 100 bar for delivery to the cylinders. ... And, even when highly ...

Regulator started out with the 26.8-foot (8.2-m) hull from its 26XO sport fishing boat, immediately redesigning around the very different storage requirements of hydrogen versus gas.

The second is that it should not be too heavy, or more specifically, that the weight of the hydrogen stored in a given material should be 6.5% of its total weight or more. Efforts to meet both ...

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 ...

Hydrogen-based electrical power with fuel cells is decades old, and was used by NASA during the Apollo missions. Its use to power military drones emerged in the late 2000s during the U.S. wars in ...

Verne’s system cools and compresses hydrogen to a 73 g/L internal density, a 33% improvement over liquid hydrogen and an 87% improvement over traditional 700-bar compressed gaseous hydrogen ...

Australian group says Japanese giant will help with technical and charter elements of the newbuilding programme ...

In 2018, Governor Jerry Brown set a target of 200 hydrogen stations by 2025, a goal to which the state has committed nearly $257 million. But last year Shell Plc quietly declined a $41 million ...

GM has condensed its Hydrotec-branded system into a “power cube” encompassing 300 individual hydrogen fuel cells, the current generation of which can put out 80 kW of net power.

FOR hydrogen to be the low-carbon alternative to power Singapore’s energy needs, there needs to be a mindset change among regulatory agencies, which still regard hydrogen as a dangerous chemical, said ...
