China, leader in EVs, could overtake the world in hydrogen mobility too -

China might be stealing a march on the world yet again. The government is targeting to build at least 1,200 hydrogen refueling stations for mobility across the country by 2025, which would mean that it would have more hydrogen stations than the rest of the globe currently boasts. The country already has the maximum number of hydrogen refueling stations in the world, although their exact numbers are not that clear. Jiang Lijun, vice president of the Chinese Renewable Energy Society, says the China has built more than 400 stations, of which 280 have begun operations. Other experts estimate the total number of active hydrogen refueling stations at 250.

    Does not matter, hydrogen is not really the future

      We don’t have any “green” hydrogen source at the moment. Hydrogen generation, currently, still releases carbon.

      Hydrogen “engines” are only ~40% efficient compared to, say, BEVs that are ~80% efficient.

        It’s important to look, not only at the vehicle, but at the energy efficiency of the system as a whole.
        Well-To-Wheel it’s referred to as.

        Gasoline: ~20%
        Diesel: ~30%
        H Fuel Cell: ~25%
        BEV (fossil power): ~20%*
        BEV (renewable): ~55%*

        *BEV is highly dependent on energy source. Anwhere from ~20% WTW from natural gas power generation to 75% from roof-mounted solar.

        Keep in mind this is a summary of a summary of a summary.

        Yup, that’s the problem.

        we absolutely do have green hydrogen at the moment https://rmi.org/insight/chinas-green-hydrogen-new-era/
