New aluminum alloy stores hydrogen

We use aluminum to make planes lightweight, store sodas in recyclable containers, keep the walls of our homes energy efficient and ensure that the Thanksgiving turkey is cooked to perfection. Now, thanks to a group of Japanese researchers, there may soon be a new application for the versatile metal: hydrogen storage for fuel cells.

Building towards 'nearly zero energy' cities

An ambitious four-year project is to develop and demonstrate replicable strategies for designing, constructing and managing large scale district renovation projects for achieving nearly zero energy cities. The results will open the way for new refurbishments that bring the EU closer to its 2020 goal of ensuring that all new buildings consume very little energy.

New ideas needed to meet California's 2050 greenhouse gas targets

California is on track to meet its state-mandated targets for reducing greenhouse gas emissions for 2020, but it will not be able to meet its 2050 target without bold new technologies and policies. This is the conclusion of the California Greenhouse Gas Inventory Spreadsheet (GHGIS), a new model developed by the U.S. Department of Energy's Lawrence Berkeley National Laboratory to look at how far existing policies and technologies can get us in emissions reductions.

Thin-film photovoltaics achieves 20.8% efficiency and overtakes multicrystalline silicon technology

In the race for higher power yields, the Zentrum für Sonnenenergie- und Wasserstoff-Forschung Baden-Württemberg (Centre for Solar Energy and Hydrogen Research, ZSW) has set a new world record. The Stuttgart researchers have improved the efficiency of CIGS thin-film solar cells to 20.8%. This figure is a record for converting sunlight into electrical energy and, for the first time, it exceeds the efficiency of market-dominating multicrystalline silicon solar cells.
