Hydrogen Combustion is a Dead-End Technology for Heavy-Duty Trucks

Earlier this month, the California Air Resources Board held a workshop on the use of hydrogen combustion engines in trucks in California as part of an agreement with the Truck and Engine Manufacturers. It was clear from the workshop that industry is interested in extending the lifetime of their investments in combustion engine manufacturing regardless of the harm it would cause to the environment or the public. While industry tried to paint hydrogen combustion engines as a “bridge” technology to hydrogen fuel cells, their own presentations undermined that very point—instead, this path is a clear dead end. We need to make sure regulators like EPA and CARB restrict its usage before it gains a fossil-fueled foothold in the marketplace.

Below I walk through the falseness of industry’s narrative and why hydrogen combustion is the heavy-duty sector’s last ditch attempt…
