Speaking to the press at the Geneva auto show, Thomas Brachmann, chief project engineer of research & development in Europe for Honda, tried to explain why his company continues to invest time and money in fuel cell cars powered by hydrogen. Honda believes battery power may be fine for smaller cars in the future but hydrogen is the way to go for larger vehicles.
Three Cheers For Electrolysis
But before we get to that, Brachmann had this to say about hydrogen production and renewable energy. “Photovoltaic electrolysis as a means of producing hydrogen is feasible, because it’s the only means we have of converting renewable energy electricity into a usable fuel and, even more important, into a proper storage media for renewable energy.
“For example, wind and sun can produce too much power during some days so either the wind-power generators are stopped, or they run and we have to sell the electricity to the grid for a very low price and, possibly, even have to pay the grid to take it because it may not be ready to accept more than it can handle.”
