Automaker Toyota wants to run entire cities in Japan (and then the world) on hydrogen. Last February, its subsidiary Woven Planet began building a connected city where urban planning technologies, such as the use of domestic hydrogen, will be tested. Its development is part of Toyota’s goal of CO2 neutrality by 2035.

Do you have a clean and portable energy source in your daily life? This is the new target for Toyota and its subsidiary Woven Planet, which has just unveiled a prototype of a portable hydrogen cartridge. The press release explains that ” the design of this cartridge will facilitate the daily transportation and delivery of hydrogen to operate a wide range of everyday applications inside and outside the home “.

For example, it could just as well be used to power our household appliances and cell phones (thanks to a small fuel cell) as it is for electric cars and motorcycles with replaceable hydrogen batteries. The prototype is in the form of a cylinder that is 40 cm long and 18 cm in diameter and weighs 5 kg when full.

The cartridge could thus be easily inserted into the walls of housings not connected to an electrical network to supply electricity or electric heaters by means of a fuel cell. Without the use of pipes, even remote places that are not connected to the mains could be supplied, and that quickly. Delivery services for these hydrogen cartridges are even being considered by the company.

Achieve CO2 neutrality by 2035

Toyota, which wants to achieve its goal of CO2 neutrality for 2035 by investing in hydrogen, believes that the use of this type of cartridge will promote the development of hydrogen as a transportable and adaptable energy carrier. On the positive side, the use of hydrogen does not lead to carbon dioxide (CO2) emissions. Moreover, ” when hydrogen is produced using renewable energy sources such as wind, solar, geothermal and biomass, CO2 emissions are also minimized during the production process “, Specifies the car manufacturer.

As an example, the production of electricity with a hydrogen cartridge will make it possible to operate a household microwave oven for about 3 to 4 hours (considering a tank with hydrogen with an electricity production of about 3.3 kWh / unit).

Woven City, the fully connected city of the future

To implement their prototype, Toyota and Woven Planet will perform validation tests at various locations, such as Woven City, a smart future “woven city” that Toyota envisions, which is currently under construction near Susono at the foot of Mount Fuji (the central Japan).

Delayed due to the COVID-19 crisis, this experimental connected city will aim to test several technologies of the future: robotics, autonomous cars, artificial intelligence … and now hydrogen cartridges. ” Woven City will offer three types of intersecting streets at the surface, one dedicated to automated driving, another for pedestrians and another for people with personal vehicles. There will also be an underground road for freight transport “Explained Toyota in a press release last year.

Woven City is expected to explore and test more energy applications using hydrogen cartridges, including mobility and household applications. ” In future Woven City demonstrations, we will continue to improve the hydrogen cartridge itself, making it ever easier to use and improving its energy density. “, The car manufacturer continues. ” The ultimate goal of this project is to achieve a CO2-neutral society where everyone can access clean energy, first in Japan and then around the world. These real-life experiences will help us learn how to best convert hydrogen into a familiar, well-used, and valued form of energy. “.
