Carbon Capture and Storage (CCS) has the potential to cut global Co2 emissions dramatically. We’re talking huge cuts. It has been estimated that a plant implementing CCS can cut emissions by 80-90 percent compared with a plant that doesn’t use CCS. Sounds great, right? Well, there are some some problems.
Cost is the number one challenge that CCS faces. “Applying it would significantly increase the cost of electricity beyond what society is likely willing to pay,” said Sarah Forbes, a World Resources Institute Senior Associate. Another challenge is that no fully integrated demonstrations have taken place. The pieces have been tested individually, but the entire puzzle is yet to be seen.
Forbes describes CCS and its current challenges in more detail:
Wednesday, Canadian Environment Minister Jim Prentice announced his government’s most recent plan for eliminating CO2 emissions. The Canadian government hopes to phase out electrical generation by modern coal technology in favor of carbon capture and storage (CCS) – the much debated and as yet unproven “clean coal” concept – nuclear power, and other, renewable sources of energy.
At a power plant at Lacq, energy company Total has upgraded an existing gas-fired boiler with CCS technology – a crucial step towards reducing carbon emissions from fossil-fuel power plants worldwide.
With renewable energy sources a long way from covering the world’s increasing demand for energy, many experts believe that developing reliable technology to allow countries to burn fossil fuels without releasing dangerous amounts of CO2 into the atmosphere is essential to avoid the worst impacts of climate change.
Have you been looking for a quick cheat sheet to understand the mechanics behind carbon capture and storage (CCS), which is one of the technologies envisioned by President Obama to allow the United States to use coal as a clean energy source? Well, global consulting company McKinsey recently published a guide to the technologies behind CCS in this nifty interactive graphic display (note that you need to sign up for a free account with the McKinsey Quarterly to view it).
Germany’s Secretary of the Chancellery, Thomas de Maizière, and Prime Minister of Brandenburg, Matthias Platzeck, together with Swedish Minister for Higher Education and Research Lars Leijonborg opened on Tuesday the world’s first “clean coal” plant, one that is ready to capture and store its carbon dioxide emissions. The 30-megawatt, $100 million Schwarze Pumpe pilot plant will burn washed lignite coal in an atmosphere of oxygen instead of regular air, producing some 10 tons per hour of compressed CO2. This compressed CO2 will then be captured and buried under a depleted gas field.
Carbon capture and storage (CCS) technology will get a chance to prove itself next week at the 1,600 MW Schwarze Pumpe coal-fired power plant in Germany. The CCS demonstration will capture up to 100,000 tons of CO2 each year and bury it 3,000 m under a nearby gas field.
The scheme uses oxyfuel technology, which relies on burning coal in pure oxygen and CO2 instead of normal air. This results in a byproduct of almost pure CO2 that is bottled and pumped underground.
The recent news that the demand for coal is climbing rapidly around the world has left many of us deeply unsettled. And a new study from Australian energy consultancy ACIL Talisman doesn’t make things sound any more cheery.
The company believes that clean coal technologies such as carbon capture and storage are unlikely to be commercially available before 2020 unless major technological breakthroughs occur in the very near future.
However, the firm predicts that both geothermal and concentrated solar will be in widespread commercial use by the 2020 target date. But none of these technologies can squelch the CO2 coming from the 40% increase in coal consumption expected by 2030.
Talking with an elected official about how to get climate change legislation with teeth on the books conjures up the quote from Otto von Bismarck: "Laws are like sausages, it is better not to see them being made."
That’s how I felt, anyway, after getting off the phone following a conference call between Sen. John Kerry (D, MA) and environmental bloggers today. Kerry demonstrates a full and deep understanding of the challenges
