Hence its supply would not be cheap, renewable nor sustainable in the long term. Hydrogen’s fuel-path inefficiency problems are also discussed in another paper by Tom Baxter of Aberdeen University, “ Hydrogen cars won’t overtake electric vehicles because they’re hampered by the laws of science ” [10].
