When the wind drops or clouds block the sun, Europe’s electricity system needs other sources of energy that can respond to changing demand. Hydropower can play an important role here. Hydropower plants can increase or lower output as demand shifts, while some can store water to generate electricity later, when it is needed most.

Plants have been doing something remarkably sophisticated for hundreds of millions of years. By capturing sunlight, leaves convert its energy into chemical energy that can be stored and used later.Inspired by this natural process, a team of European researchers has spent nearly four years developing a system that uses sunlight to split water, producing green…

A biorefinery in Spain is turning household organic waste and sewage sludge into coatings, fertilisers and biodegradable bags. In the Netherlands, a company is producing a plant-based chemical building block for new bottles, films and fibres. Together, they show how Europe is exploring ways to rely less on fossil raw materials, an approach that could…
