A tree may have the answers to renewable energy

Through an energy conversion process that mimics that of a tree, a University of Wisconsin-Madison materials scientist is making strides in renewable energy technologies for producing hydrogen.

Improving the cost and efficiency of renewable energy storage

A major challenge in renewable energy is storage. A common approach is a reaction that splits water into oxygen and hydrogen, and uses the hydrogen as a fuel to store energy. The efficiency of 'water splitting' depends heavily ...

An improved, cost-effective catalyst for water-splitting devices

By replacing platinum with molybdenum in photoelectrochemical cells, scientists from two EPFL labs have developed a cheaper and scalable technique that can greatly improve hydrogen production through water splitting as a ...

Synthetic natural gas from excess electricity

"Power to gas" is a key concept when it comes to storing alternative energy. This process converts short-term excess electricity from photovoltaic systems and wind turbines into hydrogen. Combined with the greenhouse gas ...

Increasing efficiency of hydrogen production from green algae

New research results from Uppsala University, Sweden, instill hope of efficient hydrogen production with green algae being possible in the future, despite the prevailing scepticism based on previous research. The study, which ...
