      They don’t have many buses like that yet and buses are always near population centers where using food waste to make biogas is simply much better in almost every way.

      As for storing excess energy sure if we’re talking solar generation but they use a lot of hydrogen too for this project and in that case pumping water up to the dam is a much easier and probably more efficient than generating hydrogen and either using it to run an engine or store in fuel cells. Fuel cells aren’t all that efficient. Overall a lot of money spent that will not at all pay for itself for that use case.

      I really struggle with why they’ve gone so heavily into generating hydrogen when there is a big lack of viable use cases. Though they’re far from alone in overestimating hydrogen, BMW and Toyota both invested heavily in fuel cell research (and BMW experimented with direct hydrogen use) and neither came out the other end a winner.

        China is pursuing lots of different energy alternatives to fossil fuels. That’s the correct approach in my opinion. We don’t know what particular approach or combination of thereof will be most efficient in the long term, the only way to find out is to try different things and see where you get. Thinking of it purely in terms of profits is a bit myopic.

          You keep thinking about the long term but have you considered that these brand new technologies aren’t widely implemented yet? I bet you would think that it’s a good idea to get a job working with computers but in the 1970s there weren’t many about. If you need some help to work all this out, I can tell you a story about this guy called Robert Wayne or something.

            This is a great example of how real progress happens outside capitalist relations. Developing something genuinely new takes a lot of false starts, and it’s hard to predict when it’s going to become profitable. No capitalist wants to invest money into an idea indefinitely without knowing whether they’re going to get a return on it. This can only be done at state level when technological advancement is pursued outside the profit motive.
