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.
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.
Tiny solar cells applied directly to a silicon chip are a potential way of efficiently and reliably powering wireless sensor networks in the future. Above all, this would simplify large-scale applications, for instance in agriculture.
Arizona State University and Sandia National Laboratories have signed a formal partnership agreement on important renewable energy challenges. The goals of the memorandum of understanding are to encourage collaborative research, build educational and workforce development programs and inform policy endeavors.
Researchers have developed a method by which molecular hydrogen-producing catalysts can be interfaced with a semiconductor that absorbs visible light. Experimental results indicate that the catalyst and the light-absorber are interfaced structurally as well as functionally.
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.
In the midst of an intensifying global water crisis, scientists are reporting development of a more economical way to use one form of the 'ice that burns' to turn very salty wastewater from fracking and other oil and gas production methods into water for drinking and irrigation.
In the latest advance in efforts to find an inexpensive way to make hydrogen from ordinary water, scientists are reporting that powder from high-grade charcoal and other forms of carbon can free hydrogen from water illuminated with laser pulses.
China's power capacity will more than double by 2030 and renewables including large hydro will account for more than half of new plants, eroding coal's dominant share and attracting investment of $1.4 trillion. China's power sector carbon emissions could be in decline by 2027.
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?
