IT Home reported on July 23 that the 2024 Paris Olympics is about to open. However, more than 120 scientists, scholars and engineers recently wrote a letter to the Paris Olympic Organizing Committee, asking them to reconsider the decision to use Toyota Mirai as the official car for the Olympics. Mirai is a hydrogen fuel cell car that only emits water from the tail pipe and can travel 650 kilometers on a single hydrogen refueling.

However, scientists point out that although hydrogen fuel cell vehicles such as the Mirai have no tailpipe emissions,But the production of the hydrogen it uses relies heavily on methane, making it more polluting than battery electric vehicles (EVs).They stressed that claims that hydrogen fuel cell vehicles can help combat climate change are misleading and that these vehicles are not as environmentally friendly as they appear.Using hydrogen fuel cell vehicles as official vehicles for such a high-profile event could damage the reputation of the Olympics.

IT Home noticed that Tesla CEO Elon Musk had also publicly criticized hydrogen fuel cells, believing that they were meaningless.

Despite the criticism, Toyota has remained a staunch supporter of hydrogen technology, which it sees as essential for decarbonizing transportation. The company is providing 500 Mirai and 10 hydrogen fuel cell buses, as well as 1,150 electric vehicles, for the Olympics.
