General Motors struck a deal with commercial vehicle manufacturer Autocar to use its hydrogen fuel-cell technology to power a range of heavy-duty work vehicles.
Hydrogen fuel cells — which use compressed hydrogen as their fuel and release water vapor as its only emission — have been in development for decades. GM has condensed its Hydrotec-branded system into a “power cube” encompassing 300 individual hydrogen fuel cells, the current generation of which can put out 80 kW of net power.
