New technique captures 78% carbon using molten tin.
Fracking in the US has relied on chemicals linked to a range of health problems but the industry claims UK operations would be far safer.
A fracking well in Pennsylvania, which saw rapid and sometimes-problematic spread of natural gas development.
Different states and countries with shale gas can benefit from the mistakes made by other regions that rushed into fracking. Here’s one state’s plan.
A fracking well injects large volumes of water, chemicals and sand to fracture rock.
Fracking fluids in Marcellus shale have contaminated groundwater but new study finds that the source is likely from surface spills, not leaks from underground wells.
Flaring at a gas well in Pennsylvania, where hydraulic fracturing has spread rapidly.
Higher hospitalization rates near unconventional wells could be linked to environmental and social stressors, such as noise and air pollution.
Shale gas league 2015: Preston 2 Fracking 0.
Those against shale gas extraction have scored a couple of wins in the north-west of England, but industry-government-researcher collusion may yet win the day.

It's too soon for a Lancashire County Council to be making a decision with such huge environmental implications.
Energy secretary Amber Rudd on the march.
With wind braced for more cutbacks, government backing of nuclear and fracking will end in tears.
Could fracking save lives?
How studying the injection technique involved in fracking also tells us something about earthquakes.
South Africa could see wells like this if the government gives the go-ahead for fracking to take place.
Fracking presents a better alternative to coal mining. Finding a way to produce the gas economically is the first challenge to getting fracking underway.
Texas: leading the ‘Shale Revolution.’
The US Geological Survey recently confirmed what many people have already felt: that the rapid spread of fracking has led to more earthquakes.
The National Transportation Safety Board made an ‘urgent’ recommendation to improve the safety of oil-carrying rail cars.
While federal agencies ponder regulations for safer oil rail cars, researchers are developing high-tech inspection and safety systems.
This derailed oil-carrying train in Ontario in March was the third from a single freight company in a month.
Derailed train cars carrying oil have more communities concerned about spills. What's behind the oil-by-rail boom and a federal agency's 'urgent' call last week for better safety?
Pennsylvania has added thousands of new gas wells over the past decade.
Study of Pennsylvania, which has had a surge in unconventional drilling with fracking, suggests a link between fracking and higher levels of radon.
There’s an energised debate over power sources in Wales.

Plaid looks left as energy manifesto fuels talk of a Green-SNP alliance.
The debate around coal seam gas exploration is highly politically charged, so it’s important to have an accurate picture of what exactly is proposed.
Is Christian Democratic Party leader Fred Nile correct when he says that 53% of Australia's landmass is under current exploration licence for unconventional mining?
Mission accomplished? Protesters outside the European parliament in Brussels.
Europe was supposed to be big business for fracking companies, but so far not so good. So what's going wrong?
Brinkmanship is back.

As tensions run high over Russia's gas supplies to the Ukraine, and by extension parts of Europe, the reality for the EU is less than perfect: it will need Russian gas for the foreseeable future.
Is fracked gas greener than imported oil?
MPs in the UK recently voted against a moratorium on hydraulic fracturing but Lancashire, the local county council under most pressure, agreed it needed more time to make a decision. MPs also agreed that…
Have fracking opponents over-estimated Cameron’s enthusiasm for fracking?
Jeff J Mitchell
David Cameron might have been forced into accepting several restrictions on fracking to avoid a Commons defeat, but one thing that has never appeared in doubt is the Conservative party leadership’s commitment…
