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?
A new Energy Department study conducted by the National Renewable Energy Laboratory (NREL) indicates that by 2025 wind and solar power electricity generation could become cost-competitive without federal subsidies, if new renewable energy development occurs in the most productive locations.
The EU-funded MANUCLOUD (Distributed Cloud product specification and supply chain manufacturing execution infrastructure) project, which was completed in July 2013, sought to boost European competitiveness by establishing a functioning online marketplace that would benefit manufacturers, suppliers and customers.
