Secrets of the first practical artificial leaf
A detailed description of development of the first practical artificial leaf -- a milestone in the drive for sustainable energy that mimics the process, photosynthesis, that green plants use to convert water and sunlight into energy -- has just been published. The article notes that unlike earlier devices, which used costly ingredients, the new device is made from inexpensive materials and employs low-cost engineering and manufacturing processes.

Chemists explain the molecular workings of promising fuel cell electrolyte
Researchers have revealed how protons move in phosphoric acid in a study that sheds new light on the workings of a promising fuel cell electrolyte.

Probing hydrogen under extreme conditions
How hydrogen -- the most abundant element in the cosmos -- responds to extremes of pressure and temperature is one of the major challenges in modern physical science. Moreover, knowledge gleaned from experiments using hydrogen as a testing ground on the nature of chemical bonding can fundamentally expand our understanding of matter. New work has enabled researchers to examine hydrogen under pressures never before possible.

Electricity and carbon dioxide used to generate alternative fuel
Imagine being able to use electricity to power your car and it's not an electric vehicle. Researchers have for the first time demonstrated a method for converting carbon dioxide into liquid fuel isobutanol using electricity.

Two-in-one device uses sewage as fuel to make electricity and clean the sewage
Scientists have described a new and more efficient version of an innovative device the size of a washing machine that uses bacteria growing in municipal sewage to make electricity and clean up the sewage at the same time. Commercial versions of the two-in-one device could be a boon for the developing world and water-short parts of the U.S.

More economical way to produce cleaner, hotter natural gas
New technology is offering the prospect of more economical production of a concentrated form of natural gas with many of the advantages — in terms of reduced shipping and storage costs — of the familiar frozen fruit juice concentrates, liquid laundry detergents and other household products that have been drained of their water, scientists report.

Butterfly wings' 'art of blackness' could boost production of green fuels
Butterfly wings may rank among the most delicate structures in nature, but they have given researchers powerful inspiration for new technology that doubles production of hydrogen gas — a green fuel of the future — from water and sunlight.

Nuclear power plants can produce hydrogen to fuel the 'hydrogen economy'
The long-sought technology for enabling the fabled “hydrogen economy” — an era based on hydrogen fuel that replaces gasoline, diesel and other fossil fuels, easing concerns about foreign oil and air pollution — has been available for decades and could begin commercial production of hydrogen in this decade, a scientist has reported.

Jellyfish inspires latest ocean-powered robot
Researchers have created a robotic jellyfish, named Robojelly, which not only exhibits characteristics ideal to use in underwater search and rescue operations, but could, theoretically at least, never run out of energy thanks to it being fueled by hydrogen. Constructed from a set of smart materials, which have the ability to change shape or size as a result of a stimulus, and carbon nanotubes, Robojelly is able to mimic the natural movements of a jellyfish when placed in a water tank and is powered by chemical reactions taking place on its surface.
