    Hydrogen is a far better option to electric, which is not actually as green as The Government and car companies push.

    I wouldn’t touch an electric car with a barge pole, because you’ll pay for it somewhere down the line.

    (PS. The best green option is not to own a car at all and use public transport. But that wouldn’t suit Government or car companies at all, so public transport is tulipe.)

      All the particles from the tyres because they are so heavy.

        What do you suggest? Lighter vehicles but more of them?

          Whether hydrogen or electric cars, the energy transition will actually drive demand for fossil fuel.

          https://judithcurry.com/2023/01/20/r...energy-future/

          Constructing, operating, and maintaining low-carbon energy systems will itself require substantial amounts of energy, with much of it currently derived from fossil fuels.
          Which gives a clue as to what to invest in.

            Until we have totally clean batteries we are just piling up trash for the future.

            Hydrogen sounds like 100% and the engines being clean.

              Tyre particle pollution does need to be a focus area. Needs a clever collaboration between the design of road surfaces and the design of the tyres.

                We are just about to order an electric car for my wife via a salary sacarfice scheme. It's seems a great deal, but even if she bought it out right, she can charge the car at work on the two days she is down there. It's great for safety, so what's not to like?

                Also, disagree with not owning a car as the best green option. It's one of the most enjoyable and useful things a person can buy. But what impact do you think we would have in this country if we all suddenly stopped driving, apart from the job losses? UK accounts for 1.1% of greenhouse gases, 22% of that is down to cars and buses.

                Though I agree we could improve road access to cities, park and ride etc to reduce city pollution.,

                  Go a watch Tesla's investor day and then come back a explain why hydrogen is going to be better than batteries. It starts 29 minutes in https://www.youtube.com/watch?v=Hl1zEzVUV7w

                  A internal combustion engine produces a lot of waste heat.

                  Currently with 100 kWh of electricity you can either.

                  1. Make green hydrogen 80% efficiency = 80 kWh of hydrogen, burn this in a ICE to produce 20 kWh work e.g. moving the car.

                  or

                  2. Transmit the electricity to the car/vehicle location 2% loss = 98 kWh of electric left. Charge car for another 5% loss = 93 kWh stored in battery, then use the electric for another 5% loss = 88 kWh of work.


                  You are going to need something exceptional to justify the difference in hydrogen over battery. I currently agree with Elon the only exceptional need is space travel, and that will be methane.

                  Please come up with a counter argument, as I haven't found one yet.

                    We're half way there. We've been talking about going down to 1 car for a while and when the wife's PCP came up they offered us a good cash back due to lack of miles used. For the last 4 months its been going well. When on site (2-3 days a week) I now catch the train I can walk 300 yds and go via Leeds or 5 min drive up to another station (free parking). It takes 5mins longer door to door. The train cost £10.80 return (*Veterans Railcard) diesel is aprox £16.00. If the wife needs the car she drops me at the station. Rail strikes are WFH or at a push a drive, which I now hate due to the most boring motorway journey in the country (Leeds to nearly Hull). We've had to use a taxi 3 times in 4 months for short journeys when there's a clash. Saving a bloody fortune with no dip in convenience.
