Those hydrogen-fueled airplane flights lasted between 10 minutes and 3 hours, in the case of a H2FLY design (H2FLY is a Joby Aviation subsidiary). Metavista's vehicle flew for a record 12 hours.

It was supposed to use 1.19 kg per 100 kilometers (2.62 lb per 62 miles). In this particular case, the consumption seems to be much higher. However, it's not as bad as it may seem at first glance.

The other hydrogen-powered vehicles on display included a Citroen light commercial van with an 8.8-lb (4 kg) tank capacity, a range of 249 miles (400 km), and refueling time of three minutes.

They come in much lighter than a typical tank of propane (~30 kg) or a full jerry can of gasoline (~25 kg). Toyota discusses the canister’s power output with a curious metric.

When Rivian posted its now legendary “tank turn” video back in 2019, it forced a lot of people to realize that electric drive could open up new possibilities for the way cars move. Now ...

As demand for green hydrogen rises, hydrogen tanks become crucial for storage in transportation, industrial, and power sectors. North America emerges as the third-largest market, with strong ...

Hydrogen demand for the station is assumed at 10 kg per hour or 240 kg per day. The proposed system consists of wind turbines, PV panels, an electrolyzer, an inverter, hydrogen tanks, and batteries.

The solid-state hydrogen tank, leveraging metal hydride technology, achieves a 23% weight hydrogen content and 6.6 kWh/kg energy density, outperforming liquid hydrogen systems.
