Green hydrogen from nature: Photocatalysis imitates plants

Green hydrogen could play a key role in the energy transition. Electrocatalytic splitting of water into hydrogen and oxygen requires huge amounts of electricity, which means the efficiency of this method for the energy transition ...

How to have an all-renewable electric grid

The main solution to climate change is well known—stop burning fossil fuels. How to do this is more complicated, but as a scholar who does energy modeling, I and others see the outlines of a post-fossil-fuel future: We ...

Increasing methane yield from biogas plants

Biogas plants produce methane along with more than 40% CO2 which has been released into the atmosphere in conventional biogas plants. Researchers from the Fraunhofer Institute for Microengineering and Microsystems IMM have ...

Creating a perfect trap for light

Whether in photosynthesis or in a photovoltaic system: If you want to use light efficiently, you have to absorb it as completely as possible. However, this is difficult if the absorption is to take place in a thin layer of ...

A communal energy hub

The amount of energy produced by renewable sources ebbs and flows. The Fraunhofer Institute for Industrial Mathematics ITWM has found a smart work-around for these fluctuations. Its scientists developed an innovative energy ...
