MIT Energy Storage Discovery Could Lead to Unlimited Solar Power

Researchers at Massachusetts Institute of Technology (MIT) have discovered a new way of storing energy from sunlight that could lead to ‘unlimited’ solar power.

The process, loosely based on plant photosynthesis, uses solar energy to split water into hydrogen and oxygen gases. When needed, the gases can then be re-combined in a fuel cell, creating carbon-free electricity whether the sun is shining or not.

According to project leader Prof. Daniel Nocera, “This is the nirvana of what we’ve been talking about for years. Solar power has always been a limited, far-off solution. Now, we can seriously think about solar power as unlimited and soon.”

Nocera has also explained that the process (video) uses natural materials, is inexpensive to conduct and is easy to set up. “That’s why I know this is going to work. It’s so easy to implement,” he said.

Other prominent scientists in the field have rushed to highlight the revolutionary potential of the new process. According to James Barber, biochemistry professor at Imperial College London, this research is a ‘giant leap’ towards generating clean, carbon-free energy on as massive scale. In a statement, he also said:

“This is a major discovery with enormous implications for the future prosperity of humankind. The importance of their discovery cannot be overstated since it opens up the door for developing new technologies for energy production, thus reducing our dependence for fossil fuels and addressing the global climate change problem.”

No news has yet been released of a predicted timescale to commercial development or mainstream adoption. However, Nocera has said that he’s hopeful that within 10 years homes will no longer be powered using electricity-by-wire from a central source. Instead, homeowners will be able to harness solar power during daylight hours and use this new energy storage method for electricity at night.

California Says Yes To Molten Solar

The California Energy Commission has approved a permit for SolarReserve to build a 150-megawatt solar plant that uses molten salt to store energy, the company announced Wednesday.
---The Santa Monica, Calif.-based start-up says its Rice Solar Energy Project will be located 30 miles from Blythe, Calif., and when running at full capacity will supply enough energy to power the equivalent of 68,000 homes annually. The project also has a 25-year power purchase agreement with Pacific Gas & Electric (PG&E).

California Says Yes To Molten Solar

---continued----
The molten salt system will enable the solar farm to store and release solar energy so that it can continue to generate electricity for up to eight hours after sunset, according to SolarReserve.

Molten salt solar plants, which have been built in Spain by SolarReserve with additional molten solar projects underway in Nevada and Sicily, work by using molten salt to retain and release heat energy.

In the case of a molten salt solar plant, heliostats--giant rotating mirrors controlled by computers to best track and reflect sun onto a specific point--reflect sun rays onto a central tower, or a series of pipes, containing a molten salt mixture. The molten salt generally consists of sodium nitrates and potassium. The solar rays heat the liquefied salt to a temperature of up to 1,000 degrees Fahrenheit. The steam from the molten salt is then harnessed to power a generator that makes electricity. Afterward, the cooled molten salt is then piped back to the tower to be heated once again.

In the case of the proposed Rice Solar Energy Project, the heliostats will be directed to a large central tower using a molten salt system developed by Pratt & Whitney Rocketdyne. The company received more than $10 million to develop more efficient molten-salt systems, as part of a Department of Energy (DOE) project sponsoring 13 companies with funds.

However, this latest California board approval does not mean this project is full steam ahead. The Rice Solar Energy Project still needs to receive approvals from both the Bureau of Land Management and the Western Area Power Administration, according to SolarReserve.The California Energy Commission has approved a permit for SolarReserve to build a... more
