First-ever global life cycle assessment of renewable energy future

A future where electricity comes mostly from low-carbon sources is not only feasible in terms of material demand, but will significantly reduce air pollution, a study published in the today's Proceedings of the National Academy ...

Solar fuels as generated by nature

(Phys.org) —Society's energy supply problems could be solved in the future using a model adopted from nature. During photosynthesis, plants, algae and some species of bacteria produce sugars and other energy-rich substances ...

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.

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 ...

Air, water and sun: The ingredients of 'green gasoline'

(Phys.org) —Mimicking a natural process perfected over billions of years to capture solar energy, researchers are creating artificial photosynthetic systems that will turn air and water into transport fuel.
