    Thanks emmar for that
    Yes, so-called Hydrogen Car of the future will USE LITHIUM BATTERIES to maintaining operation TRACTION power.

    However, one of the MAJOR Negatives for HYDROGEN is energy efficiency of EV compared to Hydrogen fuel cells.
    The car is actually driven by electric motors supplied with ELECTRIC ENERGY. The fuel cells cannot produce all full energy flow alone to the cars motion.

    The future is… hybrid?

    While hydrogen fuel cells offer a clean, energy-dense power source for the transport sector, the technology is currently expensive with limited supporting infrastructure. Despite this, hydrogen power appears to be developing as the forerunner for long-range transport and with the benefit of a more lightweight propulsion system than the battery cell alternative. Recent commercial investment in hydrogen powered vehicles has seen the development of hydrogen-powered technologies for , and . Once the technology is sufficiently developed, hydrogen has the potential to increase range and address the issue of charging time, particularly for larger battery packs.

    However, at present, lithium-ion battery technology remains the most commercially advanced and practical solution for powering passenger and other lightweight electric vehicles. With set to be installed across UK motorway service stations as part of the Government’s £40bn energy network investment programme, and with more funds on the way to help prepare the country for greener transport methods, the take-up of battery electric vehicles only looks set to proliferate over the next few years, as consumers’ range anxiety is addressed and EV ownership becomes more normalised.

    AND
    SOME HYDROGEN Supplies also produce carbon dioxide. What are they really not GREEN afterall!

    Hydrogen fuel cell EVs — the drawbacks

    The technical challenges facing hydrogen fuel cell electric vehicles are the availability and clean production of hydrogen and the utilisation of hydrogen as a power source.

    The production of hydrogen requires significant amounts of energy, so the way it’s produced is critical to its environmental impact. Despite hydrogen being a colourless gas, it’s referred to by a range of colours that indicate the environmental impact of its production, for example:

    Grey hydrogen is produced from fossil fuels in a process that releases CO2 into the atmosphere. This is currently the cheapest and most common form of hydrogen.Blue hydrogen is also produced using fossil fuels, but the resulting CO2 is captured to limit greenhouse gas emissions. The carbon capture process means that blue hydrogen is more expensive than its grey counterpart. The UK government’s recently announced investment in the hydrogen economy leans heavily on blue hydrogen production. However, there are doubts over just how clean the process truly is, with some figures suggesting that 5-15% of the CO2 produced is emitted, which could lead to millions of tonnes of CO2 being released into the atmosphere annually.Green hydrogen is produced using electricity from renewable energy sources such as wind and solar, making it the cleanest form of hydrogen. One of the most promising options for green hydrogen uses electricity from renewable resources to power the electrolysis of water. Chemistry plays a critical role in this process, which splits water into hydrogen and oxygen. Electrolysers are differentiated by the electrolyte material and operating temperature. Some examples include alkaline electrolysers, proton exchange membrane electrolysers and ion exchange membrane electrolysers. The cost of green hydrogen is ultimately much greater than blue or grey due to the cost of the electrolysers and the electricity required to operate them.WHO said hydrogen was in fact a green substitute GAS?
