New process provides renewable fuel

Pyrolysis bio-oil is produced by rapidly heating the forest residues in an oxygen-free environment and then rapidly cooling the products formed. By co-gasification with black liquor, a renewable fuel is produced.

Could metal particles be the clean fuel of the future?

Metal powders, produced using clean primary energy sources, could provide a more viable long-term replacement for fossil fuels than other widely discussed alternatives, such as hydrogen, biofuels or batteries, according to a new study.

Economical, efficient, sustainable - thermochemical storage 'reloaded'

Energy researchers have put into service an innovative thermal storage system that uses lime as the storage medium. The lime storage system is a further development of an initial prototype and can store energy more economically and efficiently. Thermochemical storage systems have the potential to save a considerable amount of energy, especially in industrial processes and households.

Electric cars: batteries with brains

The battery is the heart of the electric car. Fraunhofer researchers have developed an energy storage device which is significantly more cost-effective over the entire life cycle in comparison with previous models. If one of the more than one hundred battery cells is defective, it can be replaced easily. Until now, the entire battery had to be replaced.

A promising new prototype of battery

Researchers have developed the first battery using sodium ions in the usual '18650' format, an industry standard. The main advantage of the prototype is that it relies on sodium, an element far more abundant and less costly than lithium.

Electric mobility contributes decisively to climate protection

The transportation sector has the capacity to nearly halve its CO2 emissions by 2050 and, hence, to contribute far more than previously thought to mitigate greenhouse gas emissions. Realizing this would require further efficiency improvement and, especially, promotion of public transport in cities, alongside with a large-scale shift to electric cars.
