Energy Storage

14 GW Energy Storage Market by 2020 in US Says EPRI

In Electricity Energy Storage Technology Options – A White Paper Primer on Applications, Costs and Benefits – a white paper by EPRI; the Electric Power Research Institute finds that if regions in need of energy storage can defer transmission investments by investing in energy storage instead, then it can pay to invest in storage instead, depending on the costs.

Another Cheap Way to Store Solar and Wind Power

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.

Thought Solar Was Hard to Permit? Try Pumped Storage!

When you consider the environmental benefits of solar power for providing electricity, it has always seemed unfair that it takes so much bureaucracy to overcome to get it built, even in the nation’s leader, California.

Whereas a natural gas power plant sails through the permitting process with ease, solar can take years and be tripped up by technicalities that don’t slow the permitting of polluting power plants…

Dr. Nocera’s Invention May be the Future of Alternative Energy. But it’s Not a Leaf!

A lab at MIT, led by Dr. Daniel Nocera, have invented a new and novel form of storing energy that may prove to be an important milestone in the development of alternative energy. In fact, the obvious utility of the process has engendered a bit of excitement, but this excitement has also generated some misconceptions about the process that I would like to clear up, now that I have a more complete understanding of how it works.

Machine Invents New Li-ion Battery

Wildcat Discovery Technologies, which is a startup company from San Diego, California, recently discovered a new, higher-capacity lithium-ion battery chemistry using a method known as high throughput screening. This could boost storage capacity of lithium-ion batteries (used in electric cars and portable electronic devices) by over 25% and extend the driving range of electric vehicles or make the vehicles cheaper.
