Energy storage using the concrete method cost only $0.78 per kilowatt-hour, far below the Department of Energy’s goal of achieving thermal energy storage at a cost of $15 per kilowatt-hour. Engineering researchers at the University [...]

That was only about a third of its theoretical capacity, but three times better than current batteries Researchers at Rice University have refined silicon-based lithium-ion technology by literally crushing their previous work to make a [...]

Compressed air into high voltage electricity The Gujarat Energy Research and Management Institute (GERMI) has developed an instrument to convert compressed air into high voltage electricity. The instrument developed by a second year mechanical engineering [...]

GeS is relatively inexpensive and non-toxic. Researchers from North Carolina State University have created flower-like structures out of germanium sulfide (GeS) – a semiconductor material – that have extremely thin petals with an enormous surface [...]

A South Australian energy firm is claiming an international breakthrough in battery technology that will help generators of solar and wind power store their energy more cheaply. ZEN Energy Systems today unveiled a computer-controlled storage [...]

It seems that sugar may be the missing ingredient for building rechargeable batteries that are more robust, cheaper, and capable of storing more energy. Researchers at the Tokyo University of Science have turned to sugar [...]

A new type of power cell can convert mechanical energy—from walking, for example—to chemical energy and store the power until it is released as electrical current. The power cell generates enough current to run a [...]

“We believe this discovery is ripe for commercialization” Engineering Researchers at Rensselaer Polytechnic Institute Use Intentionally Blemished Graphene Paper To Create Easy-To-Make, Quick-Charging Lithium-ion Battery With High Power Density Engineering researchers at Rensselaer Polytechnic Institute made a [...]

Provides continuous nanoWatt power for over 20 years When installing micro-electronic devices in locations that are expensive or hard to reach, or just downright dangerous, you don’t want to have to keep returning to swap [...]

Their approach depends upon the day ahead forecast of load variation, market prices, and photovoltaic generation. An economically feasible way to store solar energy in existing residential power networks is the subject of an award [...]

Could herald significant advances in the design of novel hydrogen storage materials For the first time, engineers at the University of New South Wales have demonstrated that hydrogen can be released and reabsorbed from a [...]

Kickstarter backers who stump up more than US$500 will be the first to get their hands on one It took Deep Thought (the supercomputer from The Hitchhikers Guide to the Galaxy) seven and a half million [...]
