It's not mentioned because it is still not practically viable in the long term. They still haven't solved the engineering problems of long term hydrogen storage and the catalyst material which facilitates the reaction between oxygen and hydrogen. Whoever solves this will be very rich indeed. Edited November 16, 2019 by nikki-red Share this post Link to post Share on other sites Share this content via...
woolyhead 15 #134 Posted November 16, 2019 I didn't realise that hydrogen would not react with oxygen without the catalyst you mention, Albert the Cat. Whenever I've seen a hydrogen/oxygen reaction it has been virtually instantaneous but without any catalyst. What does the catalyst do?

ads36 205 #135 Posted November 16, 2019 What hydrogen/oxygen reaction have you seen that's instantaneous ? Are you talking about combustion ? - even that needs an ignition source. A hydrogen fuel cell isn't combustion. It's a transfer / exchange of electrons, and that process needs a catalyst. Share this post Link to post Share on other sites Share this content via...
woolyhead 15 #136 Posted November 18, 2019 The reaction I'm referring to is the one where hydrogen is collected in a test tube and air (oxygen) is let in and a spark ignites the mixture. It might not be literally instantaneous but it's pretty quick. Share this post Link to post Share on other sites Share this content via...

Spontaneous and instantaneous are two very different things where chemical reactions are concerned. You can buy fuel cell cars. Toyota have been making them for quite a while now. You'll need deep pockets though, the Toyota Mirai is upwards of £60k. Share this post Link to post Share on other sites Share this content via...

He was saying there only a handful of stations in the UK that offer hydrogen refuelling which means you REALLY have to plan where you're going to go with the car and by comparison at the very least, with an electric car you can plug it in to the 3 pin socket and recharge - even if it will take about 2 days.

ITM Power which are moving from the Advanced Manufacturing Park to Bessemer Park (Sheffield - not the Rotherham Bessemer Park) on Shepcote Lane next to J34 M1 Meadowhall. Hopefully this Hydrogen producing company will be making more Hydrogen filling faciliites locally. Share this post Link to post Share on other sites Share this content via...

What for is it for cars to top up, Nobodys got one or ever will have more pie in sky like E V instead of trying to kid people in to buying one the gov should put a pool of say 500 in every city similar to car sharing to try them out Share this post Link to post Share on other sites Share this content via...

Will this cater mostly for E . V as as all petrol . / deisel cars wont exist in 20 years time . Share this post Link to post Share on other sites Share this content via...
DeZeus 11 #143 Posted November 22, 2019 When I got my first Hybrid it was great for me being say a retired person, who can afford the time to wait for it, To charge up time wise, I enjoyed having it, using it, low tax, low fuel costs, however after having it 3 years, I replace it with a less complicated Hybrid, not having to control the retarder paddles, which like anything new was quite fiddly to work! Or to get used too. In the three years I had expected the technology to have progressed more, so the next time I change my car, I hope there will be much more innovations with better choice in the future, I would also like to test the Vauxhall/GM hybrid option SUV.

DeZeus 11 #144 Posted November 22, 2019 One of My neighbours says he favours the Hydrogen Cell, but I suspect he's just putting off getting a Hybrid at all! As the infrastructure simply doesn't exist in this area yet. Share this post Link to post Share on other sites Share this content via...
