Tesla CEO Elon Musk has made it repeatedly clear through the years how much he despises fuel-cell powertrains.
However, as tough emissions regulations continue to crank up for heavy-duty trucks, Musk’s narrow focus on all-electric is proving to be the exception rather than the rule.
Iconic engine manufacturer Cummins announced earlier this year a fuel agnostic approach to slashing emissions, focusing on maximizing the capabilities of internal combustion with various low-carbon fuels including hydrogen, propane and natural gas. All three of those fuels have lower or even negative carbon equivalents such as green hydrogen, biopropane and renewable natural gas.

Cummins is also pursuing fuel-cell and all-electric powertrain development during what they say will be a 40-year transition to Destination Zero.
