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.
Algae are organisms useful in many ways in the transition towards a bio-economy. Even in a cool climate as in Finland, algae might be used to produce biochemicals and biofuels, besides use in capture of industrial carbon dioxide emissions.
Despite the fragmented state of global climate policy, such front runner action could reduce future global warming by more than 1 degree if it induced others to join by 2030. This is shown by a study now published by an international team of scientists.
In Inorganic Chemistry, Dr. Dan DuBois at Pacific Northwest National Laboratory shares three fundamental discoveries made to build catalysts that drive the storage of electrical energy inside chemical bonds.
On behalf of the Berlin Senate Department for Urban Development and the Environment, a consortium led by the Potsdam Institute for Climate Impact Research (PIK) analyzed scenarios and developed recommendations how to achieve climate-neutrality.
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.
The Institute for Advanced Sustainability Studies (IASS) together with CERN (European European Organization for Nuclear Research) reached an important milestone on February 20th with the successful testing of a prototype superconducting cable able to carry 20 kA of current.
MIT spinout XL Hybrids is upfitting (and retrofitting) gas and diesel commercial vans and trucks with fuel-saving 'add-on' electric powertrains whose batteries are charged through energy generated by braking.
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.
The German Aerospace Center is testing the performance and durability of reflectors and receivers for solar power plants in Ouarzazate, Morocco and in Bokpoort, South Africa. These quality controls are the first to permit an assessment of solar power plant component quality and longevity.
