I seem to remember BMW having invested in hydrogen technology; maybe that's been canned now, but perhaps they're not ready to commit fully to another unproven post-gasoline power source.
- gambiting 12y agoI honestly do not understand why people get excited about hydrogen as power source. It escapes out of any container you put it in - a regular hydrogen tank will lose all of its contents within 3-4 weeks. A 70kg lead bottle only holds 1kg of Hydrogen. The power density is an order of magnitude lower than that of petrol,so a car using it as fuel will use hundreds of liters to get anywhere. And most importantly - there is literally zero of it in pure form here on Earth. It needs to be extracted first and then cooled down into liquid which costs a lot of energy. These are all problems that don't really have good solutions.
- sandstrom 12y agoIt surprises me to. I guess it's mainly oil companies that get's excited about hydrogen, because it can be produced from hydrocarbons (and serves as a chimera, to extend petrol's life): https://en.wikipedia.org/wiki/Hydrogen_production https://en.wikipedia.org/wiki/Hydrogen_production
