DID YOU KNOW OF THE NEW BREAKTHROUGH IN SOLAR POWER TECHNOLOGY?


[+] ballot by justanother

Just this week, MIT announced a new development in solar power research that allows solar energy to be stored. Imitating the natural photosynthesis performed by plants, MIT researchers used the sun's energy to split water into hydrogen and oxygen gases that can be later recombined inside a fuel cell, creating carbon-free electricity.

The major issue with solar power was its dependency on the availability of sunlight because storing extra solar energy for later use was very expensive and inefficient. This solar energy storage solution however appears to be both inexpensive and efficient and uses abundant, non-toxic natural materials.

Some say could be the start of a new hydrogen-based economy. Others are concerned about the costs and efficiencies of storing hydrogen and using power cells.

last I checked, it's called hydrolysis, and it's nothing new.

it's like saying the great scientist at LCD university just invented a revolutionary device that allows you to go from one place to another at great speed, and it's round piece of metal with some rubber attached to it.

must have been a slow news day.

You are right, hydrolysis is nothing new. However, I think the breakthrough here is the new catalyst that produces oxygen gas from water, simplifying the energy storing process in the fuel cells.

It consists of cobalt metal, phosphate and an electrode, placed in water. When electricity from a photovoltaic cell, a wind turbine or any other source runs through the electrode, the cobalt and phosphate form a thin film on the electrode, and oxygen gas is produced. Combined with another catalyst, such as platinum, that can produce hydrogen gas from water, the system can duplicate the water splitting reaction that occurs in plants during photosynthesis.

Currently available electrolyzers, which split water with electricity and are often used industrially, are not suited for artificial photosynthesis because they are very expensive and require an environment that has little to do with the conditions under which photosynthesis operates.
