The climate emergency requires action now, and practical hydrogen is too far off.
Sorry, Tim, I have to disagree.
Battery electric cars are a transient and useful step, but they are not the long term solution. Hydrogen is the only non carbon based liquid energy store that will allow travel as we know it to continue. It can power fuel cells, jet turbines and, internal combustion engines. Batteries are expensive and polluting to make, heavy and have re-cycling issues.
Global warming, and its consequences, is not going to be slowed by focussing on reducing CO2 output from automotive transport in developed and developing countries.
IF Ms Thunberg and her friends at Extinction Rebellion are right, radical change is needed, NOW.
Immediately stopping the mining of coal and fossil fuels and its burning to make electricity, steel, chemicals and so forth, coupled with the banning of all forms of air and sea travel that use fossil fuels will do it.
The resultant social chaos, economic collapse and global pandemics will return our CO2 levels to pre-industrial revolution levels.
I'm glad I'll be dead before that happens.
