A new way to extract hydrogen gas from liquid carriers is faster, cheaper, and more energy efficient, researchers say.

A solar "mini-refinery" that can turn sunlight and air into carbon-neutral fuels has proven its effectiveness over the course of years, researchers say.

Genetic modification can keep poplar trees from emitting greenhouse gas into the atmosphere, while not messing with their growth potential.

Understanding why platinum is the best catalyst for splitting water could lead to cheaper ways to make hydrogen fuel.

Chemicals called siloxanes from everyday products are "supercharging" landfill gas. It's a problem now, but it could yield more green energy in the future.

A new way to combine sewage sludge and restaurant grease is the most efficient way to make methane yet, say researchers.

A new catalytic reactor can take carbon dioxide, one of the most common greenhouse gases, and turn it into a pure form of liquid fuel.

The way diatoms—algae that produces 20% of the Earth's oxygen—harness solar energy could lead to cheaper, more efficient biofuels.

A new electrolysis system splits seawater to create hydrogen fuel more quickly than other methods.
