Through innovative battery design and packaging technology, Toyota and its subsidiary Woven Planet have launched a prototype of a lightweight portable hydrogen cylinder, hoping to provide green energy that is convenient for daily life.
The hydrogen Cartridge is cylindrical in shape, 40 cm long and 18 cm in diameter. It weighs 5 kg filled with hydrogen and has a capacity of about 3.3 kWh, depending on the efficiency of fuel cells that convert hydrogen into other energy sources. For the convenience of carrying, there is also a small handle on the top of the hydrogen cylinder that can be used as a switch.
Can be used in many areas
Our understanding from the design, the hydrogen tank can be used as an “exchange hydrogen battery” for electric vehicles, electric devices and drones, or it can be used in off-grid buildings, using fuel cells to power houses and heaters. Basically, it is very similar to the gas bottle used for BBQ.
It can be replaced according to demand and use, and then go to the hydrogen refueling station to fill up with hydrogen. In the future, Toyota and Woven Planet also hope to provide delivery service, and will deliver the hydrogen tank to the place where it is needed.
Toyota wants hydrogen to power Japanese cities. Toyota announced in 2020 that it will launch a town-building project “Woven City” near Susano City, Shizuoka Prefecture. The residential design combines autonomous driving, robots, and hydrogen energy. It will naturally test and verify hydrogen tanks there in the future. The plan was launched last year.
