Toyota has developed a new hydrogen fuel cell system to suit the needs of commercial vehicles, including HGVs.

The new third-generation powertrain promises the same durability as a conventional diesel engine.

It will be utilised in both passenger cars and commercial vehicles, with a market introduction planned for 2027.

Building on the first- and second-generation fuel cell systems, Toyota's latest solution is more compact, cheaper and more efficient.

Fuel efficiency is said to be 1.2 times better, improving range by 20%.

Toyota also claims a "significant" production cost reduction.
