Europe: 50% renewable energies by 2030 possible with greater integration

By 2030 around half of all electricity in Europe should come from renewable energies in order to reach EU climate targets. This applies to Germany, France, the Benelux countries, Austria and Switzerland. Varying volumes of national wind and solar supply can be balanced out through the cross-border integration of power systems.

Distributed technique for power 'scheduling' advances smart grid concept

Researchers have developed a new technique for 'scheduling' energy in electric grids that moves away from centralized management by tapping into the distributed computing power of energy devices. The approach advances the smart grid concept by coordinating the energy being produced and stored by both conventional and renewable sources.

Solar fuels: how planes and cars could be powered by the sun

Research in solar-derived liquid fuels, or solar fuels, aims to make a range of products that are compatible with our energy infrastructure today, such as gasoline, jet fuel and hydrogen. The goal is to store sunlight in liquid form, conveniently overcoming the transient nature of sunlight.

New research simplifies recycling of rare-earth magnets

Researchers have now pioneered a process that could enable the efficient recycling of two rare-earth metals, neodymium and dysprosium. These elements comprise the small, powerful magnets that are found in many high-tech devices. In contrast to the massive and energy-intensive industrial process currently used to separate rare earths, the method works nearly instantaneously at room temperature and uses standard laboratory equipment.

Better switchgrass, better biofuel

Switchgrass is an excellent candidate for biofuel production. However, growing and processing switchgrass is barely profitable. It lacks qualities, such as high biomass yield, needed to maximize biofuel production. To breed switchgrass that has the optimal combination of traits, the researchers tried evaluating plants using the Smith-Hazel Selection Index.

Using solar energy to melt aluminium

Researchers and industry are cooperating within the SOLAM (solar melting of aluminium in a directly radiated rotary kiln) project to develop a method by which aluminium foundries could use solar energy to melt this metal. The method would allow the companies to reduce their electricity consumption to a great extent and substantially lower their carbon dioxide emissions.

Adding chemicals could make future battery technology safer

In a study that could improve the safety of next-generation batteries, researchers discovered that adding two chemicals to the electrolyte of a lithium metal battery prevents the formation of dendrites ?-'fingers' of lithium that pierce the barrier between the battery's halves, causing it to short out, overheat and sometimes burst into flame.

Key to quick battery charging time

Researchers have discovered the structure and transport properties of the 'intermediate state' in lithium-ion batteries - key to understanding the mechanisms of charge and discharge in rechargeable batteries. These findings may help accelerate battery reaction speed and significantly shorten battery charging time.
