Water and sunlight the formula for sustainable fuel

An Australian National University (ANU) team has successfully replicated one of the crucial steps in photosynthesis, opening the way for biological systems powered by sunlight which could manufacture hydrogen as a fuel.

A semi-artificial leaf faster than natural photosynthesis

A cooperation between chemists and biologists resulted in a new method for the very efficient integration of photosynthetic proteins in photovoltaics. Their recent report offers a new immobilization strategy that yields electron transfer rates exceeding for the first time rates observed in natural photosynthesis.

Solar energy that doesn't block the view

A ew type of solar concentrator that, when placed over a window, creates solar energy while allowing people to actually see through the window. It is called a transparent luminescent solar concentrator and can be used on buildings, cell phones and any other device that has a flat, clear surface.

Asian inventions dominate energy storage systems

In recent years, the number of patent applications for electrochemical energy storage technologies has soared. According to a new study, the largest volume of applications by far is submitted by developers of lithium batteries. The study offers a first differentiated analysis of which energy storage technologies will be viable in the exit from fossil-fuel energy. In this area, European and US companies are falling behind economically, as Asian companies apply for a substantially higher number of patents.

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.

Tidal stream and wave power - a lot still to prove

Global installations of tidal stream and wave power are set to grow to 148MW and 21MW respectively by the end of this decade, from almost nothing today, but these are still trifling amounts in the context of the world?s power system.

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.
