Fuel from Water and Carbon Dioxide Using Sunlight

  1. Scientists from the California Institute of Technology (CalTech) , based at Pasadena, California, USA have come up with a way to convert water and carbon dioxide into fuel using sunlight and an oxide of a naturally occurring rare earth metalceriumas a catalyst.
  2. The device uses the Sun՚s rays and cerium oxide to break down carbon dioxide and water in the air into a gas mixture of carbon monoxide and hydrogen gases known as synthesis gas, or syngas, as it is also commonly called. It can then be converted into liquid fuels through well established processes.
  3. The development of the device is significant because while hydrogen is particularly viable as an alternative transport fuel, its production by currently used technology is inefficient.
