Solar power storage units reduce costs of the Energiewende
The increasing share of electricity based on solar and wind power results in an increasing load of distribution and transmission grids. At the 'Helmholtz Institute Ulm (HIU) for Electrochemical Energy Storage', ...
Climate change a 'fundamental threat' to development: World Bank
Global governments must dig deep to combat climate change, the World Bank chief said Thursday, describing it as a "fundamental threat" to development.
Packing heat: New fluid makes untapped geothermal energy cleaner
More American homes could be powered by the earth's natural underground heat with a new, nontoxic and potentially recyclable liquid that is expected to use half as much water as other fluids used to tap into ...
X-ray study images structural damage in lithium-ion batteries
Charging lithium-ion batteries too quickly can permanently reduce the battery capacity. Portions of the energy storage structure are thereby destroyed and deactivated. These structural changes have been visualized ...
Green energy investments worldwide surge 17 percent to $270 billion in 2014
Global investments in renewable energy rebounded strongly last year, registering a solid 17% increase after two years of declines and brushing aside the challenge from sharply lower crude oil prices.
Solar beam collectors, key to enhancing solar power
New technologies could soon bring more effective ways of harvesting solar power. That is the case with small size concentrated solar power, or CSP. It is a relatively new technology compared to the more mature photovoltaic ...
Catch-release-repeat: Study reveals novel technique for handling molecules
Like vast international trading companies, biological systems pick up freight items (in the form of small molecules), transport them from place to place and release them at their proper destination. These ...
Airships – the future of aviation?
Researchers from the University of Lincoln, UK, have completed a three year investigation into stratospheric passenger airships as part of a multi-national engineering project designed to provide a future ...
Solar eclipse will test Germany's green power grid
Will next week's partial solar eclipse turn off the lights in Germany?
Team deploys world's highest peak-power laser diode arrays
Lawrence Livermore National Laboratory (LLNL) has installed and commissioned the highest peak power laser diode arrays in the world, representing total peak power of 3.2 megawatts (MW).
New research could lead to more efficient electrical energy storage
Lawrence Livermore researchers have identified electrical charge-induced changes in the structure and bonding of graphitic carbon electrodes that may one day affect the way energy is stored.
A model capable of simulating power fluctuations in large grids of photovoltaic power stations is patented
Iñigo de la Parra Laita, an industrial engineer of the NUP/UPNA-Public University of Navarre, has focused his PhD thesis on the grid integration of large photovoltaic power stations. Among the contributions of his research, ...
Water in Oregon pipeline is tapped for electricity
Hydropower completes greening of Norway
The Norwegian energy supply can be sustainable by 2030, according to new research. Politicians simply have to keep their promises.
