Toyota showcases its next-generation hydrogen-powered Mirai model at Wednesday’s Tokyo Motor Show, but with the technology still lagging behind electric, the Japanese firm is hoping for an Olympic boost. The automaker is a lead sponsor of the global sporting event through 2024, and will include around 500 of the new fuel-cell vehicles in a 3,700-strong fleet to be used during the Tokyo Games next summer. Adoption of fuel-cell electric vehicles (FCEVs) has been slow compared with electric cars powered by lithium-ion batteries. By the end of 2018, there were just 381 hydrogen stations in service worldwide, while there were 5.2 million lithium-ion battery recharge stops. Supporters say the technology has plenty to offer in the transition to climate-friendly vehicles, including zero CO2 emissions from operation, faster recharging and more range per recharge.
