Some Skepticism on Solar Thermal Power’s Storage Potential

January 24th, 2012 | by John Farrell

Earlier this month, New York Times reporter Matt Wald had a piece on the role of energy storage in supporting the expansion of renewable energy. However, his specific focus on solar thermal power generation overlooks the potentially high costs of relying on solar thermal power and also overlooks the potential for distributed “storehousing” of renewable energy.

Another Cheap Way to Store Solar and Wind Power

May 4th, 2011 | by Susan Kraemer

UK startup Isentropic Energy has proposed the simplest of thermal energy storage systems, according to Powermag. Two large containers of gas and gravel, one hot (500C) and one cold (–160C) provide the temperature difference to operate a heat pump. Off-peak surplus wind power or solar energy is used to heat up the contents of the hot tank and to retain that temperature

One Way the Smart Grid Will Make Cheaper Heat (+ Wind Storage!)

Ceramic electric thermal storage (ETS) heaters that are the perfect way to use cheap off-peak electricity which goes begging for customers at night. Some 25 Terawatt-hours of wind energy went to waste in 2010 because there's just not enough of us burning the midnight oil
