Southwest Research Institute (SwRI) has upgraded its hydrogen-powered heavy-duty internal combustion engine (H2-ICE) with a state-of-the-art turbocharger. The upgrades have significantly improved performance across the board, making the engine competitive with current long-haul diesel engines focused on fuel economy while maintaining near-zero tailpipe emissions.
I remember watching a video about how many hydrogen tanks would be necessary to have the same autonomy as existing cars (I honk this was relates to Toyota’s hydrogen engines). It required an entire trunk full of compressed gas.hopefully this will change things.
