storing solar energy in h2o - home energy storage

Daniel Nocera, a professor at MIT, said the key to sufficient solar energy is water.
Nocera and his MIT colleague Matthew Kanan will publish a technical paper on Thursday describing what they claim to be a breakthrough in solar storage.
The idea is to use the energy of solar photovoltaic panels (
Or other power supplies)
Break down water molecules into hydrogen and oxygen
These gases will be stored and used in later fuel cells in order to power when the sun does not shine.
The concept is closed.
Cycle System: running hydrogen and water through a fuel cell generates water, which can be captured and used again.
Hope in 10 years, cost-
Effective systems that combine clean energy generation and storage can be designed to be cheap for people around the world.

"My plan is that when people see it, they see it's easy to do and they start working.
Nocera said: "The core scientific discovery of artificial photosynthesis is to find a way to break down oxygen from water with relatively cheap and benign materials. The catalyst--
Made of cobalt phosphate-
He said that it can be operated in clear water under atmospheric pressure and has more potential than existing methods.
Commercial electrolytic devices have separated hydrogen atoms from water.
For example, electric gas stations can be used-

A complete system envisioned by MIT researchers separates hydrogen from oxygen.
Once stored, the two gases will be powered into the fuel cell using a second catalyst such as platinum.

This work is called a "major achievement ".
But he said some improvements were still needed before the "hydrogen economy" could be realized.
"Now systems that produce hydrogen and oxygen from water require a lot of land and materials to make catalysts.
"The initial result looks promising, but it doesn't meet everything you need in the catalyst," he said . ".
Turner's research focuses on improving methods for collecting light energy to crack water molecules.
MIT researchers have found that they claim solar panels can make hydrogen and oxygen, which can be stored and used to power fuel cells when the sun does not come out.
Inspired by the process of photosynthesis, Nocera spent 25 years studying how to utilize the energy in the bond of water molecules.
He envisioned a complete break with the existing distribution infrastructure, where each household could produce and store enough electricity to achieve self-power supplysufficient.
Today, when the solar panel generates more power than the one used by the home, excess power is simply fed back into the grid and subtracted from the homeowner's utility bill. In an off-
In power grid applications, the excess is put into the battery.
However, due to the very low storage costs, remote power plants using contaminated fossil fuels are completely excluded.
"It's not entirely practical, but because it's easy, people are everywhere," Nocera said . ".
"As a scientist, I can play outside the rules box.
He said that colleagues in the electrical and mechanical engineering department of the Massachusetts Institute of Technology have already worked on the research, and the Massachusetts Institute of Technology has obtained the patent for the research.
The work came out of college.
An extensive energy initiative was launched in 2006.

Demand or "schedulable" energy storage hinders the widespread use of renewable energy sources such as solar and wind.
But this is a very active research and development area for centralized power plants.
The latest generation of solar thermal power plants will store hot water or molten salt to provide power for hours or even days.
If appropriate, the battery or pressurized air in the underground structure is also considered a viable grid storage technology. But wide-
In people's homes, large-scale distributed generation combined with hydrogen fuel cells is just a vision at this point.
Turner said many researchers are pursuing the same goal of splitting water into hydrogen without losing too much energy.
Although the current electrolytic equipment is expensive, the challenge is to design a system that is efficient enough and cost less.
"If we succeed, then we will compete with the electrolytic equipment," he said . "
"If not, we have to find another way to get hydrogen.
