Solar and wind energy may stabilise the power grid

(Phys.org)—Renewable energies such as wind, sun and biogas are set to become increasingly important in generating electricity. If increasing numbers of wind turbines and photovoltaic systems feed electrical energy into ...

Electricity from straw

Researchers have developed the first-ever biogas plant to run purely on waste instead of edible raw materials -- transforming waste into valuable material. The plant generates 30 percent more biogas than its predecessors. ...

Production of renewable gas from waste wood

KIT's researchers succeeded in producing renewable methane from a biomass-based synthesis gas mixture in their pilot plant for honeycomb methanation. The quality of this synthetic natural gas (SNG) is comparable to that of ...

Detecting leaks in biogas plants by laser

Servicing biogas plants is challenging. Leaks from which methane escapes are particularly problematic – from a security, a technical, an economic as well as an environmentally friendly perspective. Researchers are working ...

French zoo to recycle dung of celebrity pandas

Not content with housing a pair of celebrity pandas that attract hordes of avid onlookers, a zoo in France has decided to put their droppings to good use by recycling them into gas and electricity.

Using wastewater as fertilizer

Sewage sludge, wastewater and liquid manure are valuable sources of fertilizer for food production. Fraunhofer researchers have now developed a chemical-free, eco-friendly process that enables the recovered salts to be converted ...
