Toyota seems to be the only ones able to do it in small vehicles well. Whereas it seems to be much easier in larger vehicles, since many more companies are bringing big vehicles to market. They use lithium batteries with the hydrogen charging the lithium batteries. I guess this is why Toyota is doing well - since they have lots of experience with hybrid vehicles.
- CydeWeys 10y agoIf you're just going to burn hydrogen in a fuel cell to generate electricity, why even bother? Why not skip the middleman and use all-electricity to start with? The only possible advantage I see hydrogen having here is quicker fill-up times, but that comes at the cost of many other downsides, the worst being lack of existing infrastructure and reduced efficiency.
- renesd 10y agoThe current Toyota car being sold can go 312 miles per 'tank', and takes 5 minutes to refuel. Which is better than Tesla EV cars. It's much easier for trains, and larger vehicles to bring the infrastructure online. Existing natural gas pipeline and storage infrastructure can be used. Probably only a big company like Toyota could pull off getting the infrastructure in place for car sized vehicles. So far they have only done Japan, and parts of California. I've seen TWh storage being quoted. Which is quite a lot higher than battery systems. Sure, if you can use the electricity directly, there is no need for storage. However, if you need to store a lot of energy, and you need the ability to send it around then gas isn't so bad. Time will tell if it all works out I guess. But from the systems selling now, it seems like it's now viable.
