There are lots of challenges facing the replacement of pollution fuelled vehicles with clean fuelled vehicles – and in the case of hydrogen fuelled vehicles, even more. Hydrogen storage tanks are both robust and expensive to withstand gas stored under both high pressure and extreme cold. Or do they? Grace has led a team of scientists at H2M to create nanomaterials from wood waste that can store hydrogen in solids, in a tank, at not much more than ambient conditions – and that can easily release energy back under the same conditions. The tanks are light and portable enough to be easily exchanged – eliminating numerous safety and distribution barriers. Coming to a “gas” station near you within 5 years.
