POWER: Diesel-Powered Fuel Cell Produces Clean Electricity. “Although several options to store hydrogen as a fuel for cars have been investigated, a practical and affordable way to store and distribute hydrogen is still the biggest hurdle to the wide deployment of green, CO2-emission-free cars. Now researchers in Europe have built a demonstration system that might be a first step in circumventing the limitations on hydrogen distribution and storage; they simply extract hydrogen from diesel fuel on the go.”
