Toyota, Woven Planet Develop Portable Hydrogen Cartridge Prototype


June 1, 2022

Toyota Motor Corporation and its Woven Planet Holdings subsidiary have announced a working prototype of its portable hydrogen cartridge. The design aims to facilitate everyday transport and supply of hydrogen energy to power several daily life applications inside and outside the home, including mobility vehicles, drones, and robots, among others. 

The two companies will conduct proof-of-concept (PoC) trials in several locations, including Woven City, a human-centered smart city of the future being constructed in Susono City, Shizuoka Prefecture, Japan.

Both companies said they are studying several viable pathways to carbon neutrality, and consider hydrogen to be a promising solution. For example, no carbon dioxide (CO2) is emitted when hydrogen is used, and when hydrogen is produced using renewable energy sources such as wind, wolar, geothermal, and biomass, CO2 emissions are minimized during the production process. Hydrogen cal also be used to generate electricity in fuel cell systems and can be used as a combustion fuel.

The group also teamed up with ENEOS Corporation to build a hydrogen-based supply chain aimed at expediting and simplifying production, transport, and daily usage, with the focus of meeting the energy needs of Woven City residents and those living in surrounding communities.

Toyota and Woven Planet touted several benefits of using hydrogen cartridges, including:

  • Having portable, affordable and convenient energy that makes it possible to bring hydrogen where people live, work and play, without using pipes. The prototype dimensions are 16 inches in length by seven inches in diameter, with a target weight of 11 lbs.;
  • Swapability for easy replacement and quick recharging;
  • Volume flexibility, to allow for several daily use applications
  • A small scale infrastructure that can meet energy needs in remote and non-electrified areas, as well as be swiftly dispatched in the case of a disaster.

The companies said that in order to use hydrogen as an energy source in homes and daily life, the technology must meet different safety standards and adjust to new environments. “In the future, we expect hydrogen will be generated with very low carbon emissions and used in a wider variety of applications,” said Woven Planet. “The Japanese government is working on a range of studies to promote the safe early adoption of hydrogen and Toyota and its business partners are excited to offer cooperation and support.”

The prototype will be showcased at the Super Taikyu Series 2022 Round 2 at Fuji Speedway on June 4 and 5, with the goal of teaching people about how hydrogen energy works and help them imagine the countless ways hydrogen can become a useful part of their daily lives.
