The idea of clean coal has been around for 40 years, but remains a pipe dream.
A political sign in West Virginia reflects the claim that the Obama administration, by developing policies to reduce carbon emission, was waging a campaign against the industry.

Scholars of communications pick apart the rhetoric behind the 'war on coal' and explain why it ultimately benefits the coal industry.
The Norwegian capital shows other cities how it's done, by setting out a tailor-made plan to reduce emissions to zero by 2030.
Carbon capture and storage can clean up coal power.

Despite advances in technology, carbon capture and storage could be unsettled by renewable upstarts.
The test site in Iceland where gases from a geothermal power plant are pumped underground and converted into minerals by reacting with basalt stone.
Storing waste CO2 in rock? Results from a test site at a geothermal plant in Iceland show that CO2 mixed with water can be turned into minerals in locations with basalt volcanic rock.
Iceland’s geothermal power plants are an ideal place to test pumping carbon dioxide underground.
An Icelandic trial shows carbon dioxide can be pumped underground and stored as rock.
Working out how Mars's carbon dioxide was turned into rock could help with carbon capture efforts on our own planet.

Countries have signed up to the Paris climate deal, but they have not yet promised the necessary cuts to emissions.
Renewable sources of energy are already more cost-competitive than coal-fired power plants with carbon capture.
New analysis reveals carbon capture at coal power plants is significantly more expensive than thought, making renewables and natural gas power generation more attractive.
New technique captures 78% carbon using molten tin.
Cooling enthusiasm. Is a key part of climate change mitigation going up in smoke?
A technology designed to reduce the effect of fossil fuels on the climate has received £1 bln in subsidies and has nothing to show for it.
Carbon capture and storage would help the coal industry survive, but it remains elusive.

For more than a decade the coal industry's favoured response to climate change was carbon capture and storage, or CCS. CCS is still the main defence, but the absence of functioning projects is making it ever more threadbare.
Replanting forests is one way to remove carbon dioxide from the atmosphere. This is a site in China.
New research shows that we'll have to remove carbon from the atmosphere for any chance of keeping warming below 2C.
Countries should make pledges to fund low-carbon research - such as developing solar technology - and development as part of global climate talks.

Countries will take emissions reduction pledges to international climate talks in Paris at the end of this year. Those pledges should also include funds for low-carbon R&D.
Another way to change the carbon balance: trees.

Divestment campaigns aim to halt the use of fossil fuels, but the climate can be also stabilized through ‘recarbonization’ techniques, such as reforestation and changing agricultural practices.
The first commercial-scale carbon capture and storage operation at a coal power plant went online last year in Canada.
Carbon capture and storage – pumping CO2 from power plants underground – is required for dramatic cuts on CO2 emissions. Why is adoption of this technology losing steam?
Renewables or oil? The former means betting each-way on energy storage. The latter means hoping to pull off a trifecta on carbon storage.
The question of whether the future will be powered by coal and oil or by renewable energy is crucially important, both to the medium-term future of the Australian economy and to the long-term future of…
Coal seam gas is only one issue for managing one of Australia’s most important geological resources.

In a recent article on The Conversation, Queensland coal seam gas (CSG) researchers argued that the industry is progressing faster than the science, leading to concerns over fugitive emissions and impacts…
CSIRO’s solar-concentrating mirrors can be used for several purposes, including creating high-energy ‘SolarGas’.
As climate negotiators meet at the United Nations’ Lima summit, which comes hot on the heels of the landmark US-China climate deal, there is a renewed focus on how the world can move to a lower-emissions…
Investing in fossil fuels for the long term? You might find your plans get pricked.
The controversy ignited by the Australian National University in October, when it decided to sell its shares in seven resources companies, has raised two important questions about divestment from assets…
