Automaker Toyota wants to power entire cities in Japan (and then the world) with hydrogen. Last February, its affiliate Bona Planet began building a connected city where urban planning technologies such as domestic hydrogen use would be tested. Its development is part of Toyota’s goal of carbon neutrality by 2035.
Do you have a clean and portable source of energy in your daily life space? This is the new purpose of Toyota and its subsidiary Bona Planet, which has just introduced a prototype of a portable hydrogen cartridge. The press release explains that ” The design of this cartridge will facilitate the daily transport and supply of hydrogen for a wide range of applications in everyday life, both indoors and outdoors. “
For example, it can also be used to power our household appliances and mobile phones (thanks to a small fuel cell), for electric cars and motorcycles with interchangeable hydrogen batteries. The prototype is 40 cm long and 18 cm in diameter in the form of a cylinder, and weighs 5 kg when full.
This way, the cartridge can be easily inserted into the wall of the house which is not connected to any electrical network, so that electricity or power heater can be supplied using the fuel cell. Without the use of pipes, even in remote places there is no connection to the electricity network and it can be supplied quickly. Delivery services for these hydrogen cartridges are even being considered by the company.
Achieve carbon neutrality in 2035
Toyota, which aims to achieve its goal of carbon neutrality by 2035 by betting on hydrogen, believes that the use of such cartridges will promote the development of hydrogen as a transportable and adaptable energy carrier. On the plus side, the use of hydrogen does not lead to carbon dioxide (CO2) emissions. In addition, ” When hydrogen is produced using renewable energy sources such as wind, solar, geothermal and biomass, CO2 emissions are also reduced during the production process. “, Specifies the car manufacturer
For example, power generation by a hydrogen cartridge would make it possible to run a domestic microwave for approximately 3 to 4 hours (considering a hydrogen tank with approximately 3.3 kWh / unit power generation).
Bona city, the fully connected city of the future
To place their prototypes, Toyota and Bona Planet will test validity in various locations, such as Bona City, a smart future “Bona city” envisioned by Toyota, and is currently under construction near Susono at the foot of Mount Fuji (Central Japan).
Delayed due to the COVID-19 crisis, this experimental connected city will aim to test various technologies of the future: robotics, autonomous vehicles, artificial intelligence … and now the hydrogen cartridge. ” Bona City will have three types of interwining streets at ground level, one for self-driving, another for pedestrians and another for people with private vehicles. An underground road will also be used to transport goods Toyota explained in a press release last year.
Bona City is expected to explore and test a number of power applications using hydrogen cartridges, including mobility and domestic applications. ” At future Bona City exhibitions, we will continue to improve the hydrogen cartridge, make it easier to use and improve its energy density. “Automaker continues. ” The ultimate goal of this project is to achieve a carbon-neutral society where everyone can use clean energy, first in Japan and then around the world. These real-life experiences will help us learn how to convert hydrogen into a well-known, well-used and acclaimed energy. “
