Toyota has reached a sales milestone for its hydrogen fuel cell electric vehicle, the Mirai, selling its 3,000th car in California.

“Toyota remains at the forefront of developing and deploying hydrogen fuel cell technology, and we believe strongly in its potential to help realize a more sustainable and zero-emissions society,” said Bob Carter, executive vice president of Toyota Motor North America.”From our success in launching the Mirai to our work in building the world’s first megawatt-scale carbonate fuel cell power generation plant, Toyota is proud to bring to market new uses for this versatile technology.”

First introduced at the Nov. 2014 Los Angeles Auto Show, the Mirai is powered by an electric motor running 151 horsepower and 247-pound-feet of torque. Arguably, the Mirai’s biggest calling card is its ultra-low emissions, emitting only water with a three-minute fill-up, capped by its unique fueling system which mixes pure hydrogen with oxygen to generate electricity, which powers the Mirai’s motors.

Over the past several years, Toyota has advanced its pole position in introducing the lesser-known hydrogen fuel to the masses, building stations, including 12 expected to open in California in 2018. Other efforts have seen partnerships with gas conglomerates and industrial gas producers such as Shell and Air Liquide to build hydrogen fueling networks, along with a bio-waste facility at the Port of Long Beach to power Mirai deliveries.

However, the Mirai continues to be dogged by low sales due to perceived, lesser marketing push than its mainstream counterparts.

At the moment, Toyota is responsible for 80 percent of all hydrogen cars sold in California. Fueling infrastructure is severely limited with only 31 hydrogen fueling stations, mostly concentrated in Los Angeles and San Francisco. This week, Toyota also announced the sale of 50 Mirai to government and private fleets in Quebec, Canada, a growing hotbed for EV activity, responsible for the first low emissions mandate in the country with a target to reduce gas-powered car use 40 percent by 2030.

Few automakers have spurred efforts for hydrogen fuel vehicle production, most notably Honda’s Clarity fuel cell vehicle and Hyundai’s new Nexo SUV, set to go into production in 2019.
