Toyota subsidiary Woven Planet creates exchangeable hydrogen cartridgeJune 10, 2022
The portable cylinder system was developed in a prototype form to bring H2 wherever needed.
Woven Planet, a subsidiary of Toyota, has developed a new form of exchangeable portable hydrogen cartridge system. The prototype makes it possible to transport and deliver zero-emission fuel wherever it is required.
The automaker has been working on developing systems to cleanly power entire cities in Japan.
Last February, the company’s subsidiary Woven Planet broke ground on its “Woven City“, located near Susono, Japan. That location will function as a cutting-edge testing location for a spectrum of different types of urban planning concepts and technologies. This includes a broadened use of H2 throughout the region.
Now, Toyota and its subsidiary have unveiled a working hydrogen cartridge prototype for the intention of providing clean fuel for “a range of daily life activities in and outside of the home.”
The cylinders are 16 inches (400 mm) long and 7 inches (180 mm) in diameter. Their target weight is 11 pounds (5 kilograms) when full. Each one will be able to provide about 3.3 kWh of usable energy, depending on the external fuel cell efficiency being used to convert the H2 contained in the cylinder back into electricity. Each one has a handle built into the top to make them convenient to lift, slipped into the slot, and twist-locked in place.
The hydrogen cartridge also has the potential to be used in passenger vehicles, motorcycles and drones.
Aside from passenger vehicles and transportation, the cylinders could also be used in units built into the walls of homes and businesses that aren’t linked to the electricity grid.
It could provide the electricity needed to power an entire house through a fuel cell. They could also be used in other applications such as remote electricity or to power home heating. If they were to have a small fuel cell built on top of them, they could also be used as large backup portable power banks for device recharging.
On a commercial level, they could be sold in a way comparable to BBQ gas cylinders. The hydrogen cartridge would be exchanged as needed and could be filled again at refueling stations. Toyota and its subsidiary Woven Planet anticipate the development for a delivery service as well. This will ensure that H2 cylinders can be delivered to any location that requires them for emission-free fuel and power.
