Sydney: Scientists are
now tapping solar energy to produce chemicals which could be
stored to create electricity and fuels.
The new technology mimics photosynthesis, the process used by
plants, by combining sunlight and water in such a way that
promises storable fuels. The process uses man-made materials.
The "solar to chemical energy conversion" process is outlined by
Yasuhiro Tachibana, associate professor at the Royal Melbourne
Institute of Technology, the journal Nature Photonics reported.
It remains a challenge to construct a device capable of producing
molecular fuels like hydrogen at a scale and cost able to compete
with fossil fuels, said Tachibana, according to a Royal Melbourne
statement.
The key to improving efficiency will be in the development of new
"nano-materials," along with efficient control of charge transfer
reaction processes.
Recent developments in the field of nanotechnology have been
leading to promising improvements in cost and effectiveness of the
conversion process, Tachibana said.
"Our future scientific goal is to establish a solar water
splitting system operated only by abundant sunlight and sea water.
Fortunately these resources are freely available on this blue
planet," Tachibana said.
