    You can also extract hydrogen from water. Except now it’s not an insanely impractical idea. Sodium batteries haven’t been invented yet, and will have a much lower energy density.

        The link is dead.

        You have an inverted view of reality. Hydrogen fuel cells are a now technology. Your idea don’t exist outside of science projects and underwhelming early demonstration versions.

          Yes, hydrogen fuel cells are a now technology. That’s why green hydrogen still represents less than a tenth of a percent of global hydrogen production. That’s why there are only more than three hundred and seventy plug in battery vehicles for every hydrogen one, to say nothing of hundred year old green technology like Vancouvers trollybuses.

          That’s why for every watt of power a hydrogen fuel cell outputs you only needed 2.3 times as many watts to power it, as compared to batteries which even after transmission and inverting losses require a whole 1.15 watts of input for every watt of output./s

          Hydrogen fuel cells are at best, a way for Shell and Chevron to stay relevant. More likely, a way to eat large quantities of money on tech demonstrators instead of proven, off the shelf replacement technologies like overhead wires or batteries.

          There are already, largely but not entirely overblown, concerns over how we can build enough electrical generation capacity to make up for eliminating oil and gas. You would need to more than double that new capacity to make hydrogen work. It may have a place in industrial applications, but transport is a dead end. We need solutions now, not expensive tech demos from startups.

            Funny, because you can replace “fuel cells” with “solar cells” and you would’ve nearly mirrored the anti-solar power rhetoric of a decade ago.

            What you’re doing is blatant Ludditism. It is closer to being a climate change denier tactic than anything honest.

              It’s funny, your quoting BP and Shell about climate change while comparing me a denier. You could disprove the solar cell argument a decade ago, but yon haven’t even bothered to try to defend hydrogen, just continuing with personal attacks on everyone vaguely critical of the oil companies magic solution.

                You’re too brainwashed to know what you’re talking about. Very likely you’re just regurgitating what the battery industry wants you to think.

                Hydrogen is obvious a zero emissions fuel. It is as self-evident as wind or solar. What you doing is the exact same thing as what climate change deniers did. Somehow argue that new green technology is secretly a scam, or it is impossible, or a trick by the fossil fuel industry. In reality, saying such obvious lies makes you the climate change denier.

                  You mean a tenth of one single percent is possibly zero emissions, the rest is a heavy emissions fuel. Hydrogen is not a new technology, hydrogen fuel cells powered the bloody moon landing, and that one had a ten percent higher efficiency than the ones you’d find in any modern, technology demonstrator, i mean vehicle.

                  Battery technology has seen continuous practical improvement in density, efficiency, and capacity over the last forty years. Fuel cells haven’t, not significantly anyway, and are just as impractical for common useage now as they were then.

                  Again, i can’t help but notice that you haven’t presented any evidence for your extraordinary claims, any reason to believe that this tech could possibly do what you claim is self evident, just make personal attacks.

                    Same story with solar cells, again. Everything starts at zero, and nothing is magically perfect from day one. You are doing exactly what climate change deniers said about all new green technologies when they first came out.

                    Meanwhile, battery cars are older than internal combustion cars. You think you have a point here, but you don’t. You are cheering on totally obsolete technology as if it is anything new.

                    In reality, you are just being brainwashed by corporate propaganda. All you’re digging your hole even deeper, and even more indistinguishable from blatant climate change denier.

          I just clicked it and it works. There’s a bunch of sodium ion batteries for sale.

          The current fuel cells that waste most of the energy and are manufactured in very small numbers for pilot programs are exactly what I’d describe as underwhelming early demonstration versions.

            Now it is working.

            But it doesn’t matter. Those are hoax products. None of them exist in the real world. You can’t actually buy them, or they are secretly some other type of battery. No one has actually seen a working sodium-ion battery in public.

            Fuel cells are already in mass production. Again, you are simply living in the early 2000s on this subject. You are wildly outdated on your knowledge.
