USA: Solar Powering Cars without Batteries

Fraunhofer ISE has inaugurated a new hydrogen refueling station demonstration project. The refueling station is publicly accessible, providing one more place for fuel cell electric vehicles or vehicles with hydrogen-burning combustion engines to get their hydrogen fix.

Solar-Powered Hydrogen Refueling Station – Obtained from

Different types of fuel cells that can utilize different fuels, but this refueling station is just for hydrogen fuel cells, which generate electricity that then powers the electric vehicles’ motors.

Due to the intermittency of wind and solar power, it is good to find ways in which these renewable power supplies can be utilized without energy storage systems such as batteries, compressed air (CAES), etc. One way is the production of hydrogen via electrolysis, which is what the Fraunhofer hydrogen refueling station does. At this refueling station, electricity form the solar panels is used to power an electrolyzer, which passes an electric current through water, causing it to liberate hydrogen. (If you don’t remember, water (or H2O) is made up of water molecules, each of which contains 2 hydrogen atoms and 1 oxygen atom. During electrolysis, hydrogen bubbles out of the water at the cathode, and oxygen bubbles out at the anode.)

The hydrogen produced while the sun is shining is stored in tanks for later use at night, or during cloudy weather.
