Toyota and Woven Planet are developing portable hydrogen cartridges

Toyota and its subsidiary Woven Planet have developed a working prototype of a portable hydrogen cartridge. The design will facilitate the daily transport and delivery of hydrogen energy.

Toyota and Woven Planet are studying a number of viable avenues for CO2 neutrality. They see hydrogen as a promising solution. When hydrogen is used, no carbon dioxide (CO2) is released. In addition, there is only minimal CO2 emissions during the production process. That is, if production is done using renewable energy sources.

Supply chain

Together with Eneos Corporation, Toyota and Woven Planet are building a comprehensive hydrogen-based supply chain. It aims to speed up and simplify production, transport and daily use. The trials will therefore focus on meeting the energy needs of the residents of Woven City and those living in the surrounding communities.

Benefits of using hydrogen cartridges

Hydrogen cartridges have a number of benefits. They are portable, affordable and useful as a portable energy solution. They make it possible to bring hydrogen to the places where people live, work and play without the need for pipes. The cartridge can also meet the energy needs of remote and non-electrified areas. Rapid deployment of cartridges in the event of a disaster is also possible.


The prototype has the following dimensions: 400 mm (length) x 180 mm in diameter and weighs about 5 kg. It is designed to be easy to replace and fast to charge. The volume flexibility also allows for a wide range of applications for daily use. For example, the cartridge could generate enough electricity to run a microwave oven for about 3 to 4 hours. The design team assumes that the final design consists of a high-pressure hydrogen tank that has an electrical output of approximately 3.3 kWh / tank.


Hydrogen production today generally takes place with fossil fuels as an energy source. This while applications are mainly found in the industry. That will change. In order to use hydrogen as an energy source in everyday life, the technology must meet various safety standards. In addition, it must be adapted to new environments. Toyota expects that in the future, hydrogen will be generated with very low CO2 emissions and used in a wider range of applications. The Japanese government is working on a series of studies to promote safe early intake of hydrogen. Toyota and its business partners are happy to provide cooperation and support.

supply chain

Toyota’s goal is to make hydrogen commonplace. This is possible if this pure form of energy becomes safe, convenient and affordable. By establishing the underlying supply chain, Toyota hopes to facilitate the use of hydrogen and allow for more uses. Woven City will research and test a range of hydrogen cartridge energy applications. Think of applications in the field of mobility, domestic applications and many future possibilities that we have not yet imagined. Together with innovators and those living in and around Woven City, Toyota will continue to promote mobility for the foreseeable future. It will continuously develop more practical applications for hydrogen cartridges. Toyota will further improve the hydrogen cartridge in future demonstrations. This makes it more and more user-friendly, while improving energy density.

Climate-neutral society

The ultimate goal of this project is to realize a climate-neutral society where everyone has access to clean energy. Toyota and Woven Planet strive to develop best practices for integrating clean hydrogen energy into everyday life. They do this, among other things, by giving demonstrations in and around Woven City.
