New emissions standards would fuel shift from coal to natural gas

Tougher EPA air-quality standards could spur an increased shift away from coal and toward natural gas for electricity generation, according to a new Duke University study. Complying with stricter regulations on sulfur dioxide, ...

'Waste heat' may economize CO2 capture

In some of the first results from a federally funded initiative to find new ways of capturing carbon dioxide (CO2) from coal-fired power plants, Rice University scientists have found that CO2 can be removed more economically ...

Carbon sponge could soak up coal emissions

Emissions from coal power stations could be drastically reduced by a new, energy-efficient material that adsorbs large amounts of carbon dioxide, then releases it when exposed to sunlight.

Scientists use fossils to discover the ancient equator

(Phys.org)—Researchers at Western University have discovered where the equator was "precisely located" 450 million years ago, which is an important breakthrough for paleontologists and planetary scientists, as well as private ...

World's oldest turtle shells stand test of time

Plucked from a pit of grey clay next to a rubbish dump in southern Poland, fossilised turtle shells resembling the battle-scarred shields of ancient warriors are the world's oldest and most complete.

Coal gasification demonstrated

DOE's National Energy Technology Laboratory (NETL) has developed a molten catalytic process for converting coal into a synthesis gas consisting of roughly 20% methane and 80% hydrogen using alkali hydroxides as both gasification ...

Methane emissions traced back to Roman times

Emissions of the greenhouse gas methane into the atmosphere can be traced back thousands of years in the Greenland ice sheet. Using special analytical methods, researchers from the Niels Bohr Institute, among others, have ...
