Researchers have developed a new way to study wake effects that includes the airflow both within and around a wind farm and challenges the conventional belief that turbines arrayed in checker board patterns produce the highest power output.
Pumped storage power plants are firmly established in the German power grid: surplus electricity can be stored for a moment and then quickly supplied during a demand peak. The BINE Projektinfo brochure 'Storing wind energy underground' presents a concept of how to reuse abandoned ore mines as pumped storage power plants.
What makes cities in India and China so frustrating to drive in - heavy traffic, aggressive driving style, few freeways - makes them ideal for saving fuel with hybrid vehicles, according to new research.
Within just three years, research partners of the EU project PECDEMO are planning on developing a practical system capable of converting over eight percent of solar energy into hydrogen. This could prove a real breakthrough in terms of practical applicability.
Storing intermittent solar and wind energy in chemical bonds for later use requires a detailed understanding of how protons flow. Researchers describe how proton relays and other factors influence the catalysts that produce the desired chemical bonds.
No more oil - renewable raw materials are the future. This motto not only applies to biodiesel, but also to isobutene, a basic product used in the chemical industry. In a pilot plant researchers now want to obtain this substance from sugar instead of oil for the first time.
At the Bjerknes Centre, researchers are exploring the potential for seasonal to decadal climate prediction. This is a field still in its infancy, and a first attempt was made public for the latest Intergovernmental Panel on Climate Change (IPCC) report.
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.
