Looks like the competition for ICE Hydrogen as the power source savior is heating up.  This is actually the 3rd different design I have seen reported.  The article also says the engine can burn either hydrogen or gas, whichever is available.  That's a new claim.

IF enough solar/wind/hydro/geothermal/tidal/nuke power is brought online, even without full grid connection and IF all the infrastructure for clean hydrogen production, storage and distribution is built,  this would enable our current level of technological lifestyle to go on.  Hydrogen packs enough energy to run the big fast SUVs, the Jet planes and the container ships.  It can heat all the homes and use the same NG pipelines currently in existence.  About the only problem it doesn't solve is all the juice necessary for the AI and Data Centers, but if they have their own dedicated generators that run on hydrogen, it solves that problem too.

The main problems I see are with the economics, the resources to build all the infrastructure and the time available to get all this done.  The technology though is straightforward and not sci-fi hopium so it will be interesting to see how this plays out.

This is the new massive hydrogen engine: 3-liter internal combustion engine for more than just cars
