Mapping the renewable energy potential below our feet (w/video)

Easy-to-access visualisation of the 'very shallow geothermal potential' of Europe has been made possible thanks to an EU-funded project. By harmonising pre-existing data relating to geological, hydrogeological, soil and climate, the THERMOMAP project has developed an open source web service, accessible to all.

Modular battery concept for short-distance traffic

Electric mobility may be economically efficient today. Battery-based electric drives can be applied efficiently in urban buses, for instance. Frequent acceleration and slow-down processes as well as a high utilization rate in short-distance traffic make their use profitable even when considering current battery costs. At the IAA International Motor Show in Frankfurt, Karlsruhe Institute of Technology (KIT) will present an e-city bus demonstrator to illustrate the concept.

More efficient production of biofuels from waste with the help of modified yeasts

A significant portion of the petroleum consumed by the transport sector must be replaced in the long term by renewable energy. Therefore, it is of the utmost economic and ecological importance to optimise the production of biofuels from renewable raw materials. Researchers have now developed yeast strains that produce bio-ethanol from waste with an unprecedented efficiency.

The next 'black gold' could be green

Recent decades have witnessed several cycles of interest in being able to exploit these organisms. Research has examined the use of algae for remediating waste water or nutrient-overloaded coastal seas, absorbing carbon dioxide from the atmosphere or directly from industrial chimneys, in beneficial products such as proteins and antioxidants, and to produce oil and liquid fuels. Given its indisputable virtues, why has microalgae not been put to use in these ways?
