A radical new process that allows hydrogen to be efficiently sourced from liquid formic acid could be one step forward in making the dream of hydrogen-powered cars an economic reality.Using formic acid to produce hydrogen has never been considered viable because it requires high temperatures to decompose and also produces waste by-products.But the University of Melbourne's Professor Richard O'Hair has led an international team of scientists in designing a molecular catalyst that forces formic acid to produce only hydrogen and carbon dioxide and at a low temperature of only 70°C.
