Generating electricity is not the only way to turn sunlight into energy we can use on demand. The sun can also drive reactions to create chemical fuels, such as hydrogen, that can in turn power cars, trucks and trains.
We’ve gotten pretty good at turning solar power into electricity, but electricity can be hard to store, making it a challenge for use right when you need it and in the transportation sector.
Living in a genuine big city for the first time, I’ve come to appreciate the beauty and significance of a skyline.
Computer simulations of galaxies growing over billions of years have revealed a likely scenario for how they feed: a cosmic version of swirly straws.
A team of Virginia Tech researchers has discovered a way to extract large quantities of hydrogen from any plant, a breakthrough that has the potential to bring a low-cost, environmentally friendly fuel source to the world.
American automaker Ford was recently crowing about its upcoming Fusion Hybrid.
For many years, most of the fuel we've been burning in our automobiles has included 10% ethanol to reduce the amount of petroleum consumed in the United States.
Nuclear power plants can produce hydrogen to fuel the 'hydrogen economy', say scientists from the International Atomic Energy Agency (IAEA) in Vienna.
People who are shopping for green and efficient cars have a number of choices on the market today.
Russian scientists still can't contact the lost Martian probe Phobos-Grunt, state media are reporting - and there's a danger it could fall to Earth with a massively toxic explosion.
A team of Kentucky scientists has found a way to 'tweak' an inexpensive semiconductor to generate hydrogen from water using sunlight.
Scientists at MIT, Tel Aviv University and the US National Renewable Energy Laboratory say they've found a way to use algae to make four times as much fuel as before.
The launch of space shuttle Endeavour, originally planned for last Friday, will be delayed at least until following the discovery of problems with a heater on a fuel line.
Researchers at the Department of Energy's Oak Ridge National Laboratory have successfully demonstrated a biohybrid photoconversion system that can convert visible light into hydrogen fuel.
A British start-up says it's found a cheap, practical way of storing hydrogen, making it a viable alternative to gasoline in cars.
CalTech researchers have designed a prototype reactor capable of transforming sunlight into liquid fuel.
A Californian company has filed a patent for a technology which it says allows CO2 and natural gas to be converted directly to gasoline.
A team at the Bristol Robotics Lab is looking into the use of urine as the fuel for Microbial Fuel Cells (MFCs), which use bacterial cultures to break down 'food' to create power.
UK researchers reckon they are on track to take carbon dioxide from the air and turn it into car fuel.
