TO THE EDITOR:
Battery-powered electric vehicles are never going to be the future until the holy grail of a small, lightweight, long-lasting battery is found. Batteries themselves are a manufacturing problem, not to mention the associated end-of-life disposal difficulties and costs, should large volumes come about.
Hydrogen for domestic use does have a safety consideration, but with good research and sound engineering practices, this can and will be overcome. I would not buy a battery car yet, and with some manufacturers already producing internal combustion engines with very low emissions, the rush to batteries must be slowed right down until hydrogen has been properly sorted.
Sadly, decisions are often made by people unqualified for the task — politicians, both national and local, who rush at fences without proper consideration. It is of fundamental importance that pollution is reduced, and quickly, but battery cars are not the way. Hydrogen must be given a chance, along with continued work on the internal combustion engine.
