One of the biggest barriers to adoption of hydrogen as a fuel for transportation is refueling. There are just 21 hydrogen fueling stations in the entire state of California. While four more stations will be opening this year, there’s an even more promising technology on the horizon. Developed by Honda R&D in Torrance, it’s a residential hydrogen refueler that uses sunshine and tap water to power a car: A 6-kilowatt array of solar panels powers an electrolysis machine that separates the hydrogen from the oxygen in water. The hydrogen is then pumped directly into the car.
