Bionic liquids from lignin

While the powerful solvents known as ionic liquids show great promise for liberating fermentable sugars from lignocellulose and improving the economics of advanced biofuels, an even more promising candidate is on the horizon - bionic liquids.

Efficient production of hydrogen by algae

Microalgae need only sunlight and water for the production of hydrogen. However, in order to make hydrogen production by microalgae economically feasible their efficiency has to be increased by 1-2 orders of magnitude. Researchers now present how an improvement in efficiency can be achieved.

Sustainable green alternatives to fertilisers could boost food and energy security

Scientists are looking at formulating sustainable fertilisers from renewable energy waste. This new area of research aims to produce a sustainable, environmentally-friendlier source of soil conditioner and crop fertiliser that could also reduce costs to farmers and potentially, with wide-spread take-up, help to slow down rising food prices.

Stinky gases emanating from landfills could transform into clean energy

A new technique transforming stinky, air-polluting landfill gas could produce the sweet smell of success as it leads to development of a fuel cell generating clean electricity for homes, offices and hospitals, researchers say. The advance would convert methane gas into hydrogen, an efficient, clean form of energy.

The immediate aftermath of an oil spill

The fate of oil during the first day after an accidental oil spill is still poorly understood, with researchers often arriving on the scene only after several days. New findings from a field experiment carried out in the North Sea provide valuable insight that could help shape the emergency response in the immediate wake of disasters.
