The company is still confident hydrogen fuel-cell powertrains will be relevant in 10 years for both commercial and passenger vehicles.

Toyota has outlined its zero-emissions vehicle strategy through 2030, promising to offer some form of electrification across its entire lineup by 2025.

The plan includes traditional mild hybrids, plug-in hybrids, pure battery-powered EVs and hydrogen fuel-cell vehicles.

Bringing basic hybrid technology to the full portfolio aligns with similar plans already announced by other automakers. To further clarify a commitment to zero-emissions vehicles, Toyota says it expects EVs and FCVs to account for more than a million sales by 2030.

"Toyota will accelerate the popularization of BEVs with more than 10 BEV models to be available worldwide by the early 2020s, starting in China, before entering other markets?the gradual introduction to Japan, India, United States and Europe is expected," the company says.

Interestingly, Toyota still hasn't backed down from its commitment to hydrogen. The company plans to continue expanding its FCV lineup, including both commercial and passenger vehicles, through the 2020s.

The Japanese automaker is also hoping to bring a solid-state battery to market by the 2020s. Nearly all such 'breakthroughs' have failed to become viable alternatives to traditional lithium-ion technology. As an apparent hedge, Toyota and Panasonic are currently exploring a joint production plan for prismatic battery technology that is already used for current hybrids and EVs.
