Renewable energies: Smartly controlled infrastructures neutralize fluctuating availability

More and more frequently, companies are generating part of their electricity themselves in order to cut costs. As far as possible, the energy is supposed to come from renewable sources? whether from a biomass-fired power plant, a solar complex or a wind turbine. Unfortunately, they are not always available. Researchers now have developed a novel, dynamic management system that compensates for their volatility.

A battery that 'breathes' could power next-gen electric vehicles

The main difference between lithium-ion and lithium-air batteries is that the latter replaces the traditional cathode - a key battery component involved in the flow of electric current - with air. That makes the rechargeable metal-air battery lighter with the potential to pack in more energy than its commercial counterpart.

European collaboration to develop highly efficient organic solar cells

The European FP7 project ArtESun aims to develop highly efficient organic solar cells with an increased lifetime and a decreased production cost. The ultimate goal of the ArtESun project is to bring organic photovoltaic technologies (OPV) towards introduction into the competitive thin-film PV market.
