The levels of forest residue bioenergy, considered to be sustainable from a forestry perspective, may provide considerable reductions in greenhouse gas emissions in European countries. Still, these reductions fall short of a 60 % threshold planned by the EU. This mismatch may have important climate policy implications.
Microscopic ciliates can increase the mobility of poisonous tar substances, PAHs, by up to 100-fold according to a new study carried out by Danish researchers. The results open new possibilities for cleaning soil that is contaminated with organic chemicals.
Stanford researchers have found that the wind industry can easily afford the energetic cost of building batteries and other grid-scale storage technologies. However, for the solar industry, the Stanford team found that more work is needed to make grid-scale storage energetically sustainable.
Phosphorus can be found in fertilizers, drinks and detergents. It accumulates in waterways and pollutes them. For this reason the German Phosphorus Platform has the goal to recover this valuable, but at the same time, harmful element from water.
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.
