  • I have a room that I want to add 1000w per hour of heat energy to

    I have the options of:

    • burning 1050W of gas per hour
    • running a 1000W theoretically lossless electric resistive heater per hour
    • running a 600W heat pump per hour

    Sure, the gas is combusting, the resistive is radiating, and the pump is moving the heat, but functionally they’re all trying to add that 1000W to the room continually for an hour. One of them is doing it a whole lot more efficiently.






  • Agreed, but 2 important things in my eyes.

    1 - renewable surpluses. As wind and solar keep ramping , hydrogen is a fantastic way to store that energy. Sure, there are efficiency losses but it’s transportable, able to be stored long term, and able to be used from small scale to grid scale applications.

    2 - total life cycle cost. There is an incredible amount of emissions embodied in evs. Haven’t seen a comprehensive analysis of a h2 vehicle but I would imagine a few hundred kilos of missing lithium is a good thing.
