Large-Scale Carbon Capture is Finally Underway

It Is No Longer Sufficient to Reduce CO2 Emissions Alone

The Intergovernmental Panel on Climate Change (IPCC), in its 2018 Special Report on Global Warming of 1.5°C , found that “all pathways to limit global warming to below a 1.5°C rise in median global temperatures forecast the use of Carbon Dioxide Removal (CDR) of about 100–1000 gigatons of CO2”, this century. That’s equivalent to removing about 6 billion blue whales of CO2.

The time is ripe for large-scale carbon capture, usage and storage (CCUS), a suite of technologies that trap carbon dioxide produced by industries and fossil-fuel power plants, then bury it underground or recycle it.


Carbon capture has been around since the 1970s but has been in limited use. There are 17 large-scale plants in the world, mostly in the US, that put away about 40 million metric tons of carbon dioxide – roughly 1% of global annual emissions.

The technology is gaining momentum. The UK Government and International Energy Agency (IEA) held a pivotal summit to kick-start carbon capture projects in November 2018, bringing together 50 international leaders, CEOs of major energy, manufacturing and finance firms.

Claire Perry, Minister of State for Energy and Clean Growth, pledged £20 million to construct carbon capture technologies at industrial sites across the UK, as part of £45 million commitment to innovation, and will invest £315 million in decarbonising industrial sites.

Britain is forecasting large-scale carbon capture by mid-2020s, said the UK Department for Business, Energy and Industrial Strategy (BEIS).

Norway is also looking to build Europe’s largest carbon-capture project. The Ministry for Petroleum and Energy revived plans to develop CCS technology with a pledge of €30 million in May 2018.

These developments could lay the groundwork for a Europe-wide boom in carbon capture, which will require significant capital investments to bring costs down.

How Does Carbon Capture Work?

A carbon capture project consists of five phases: generating CO2, capturing the emissions (a two-part process), transporting it with trucks, and injecting it deep underground and then monitoring it.

Capturing CO2 is most effective at combustion sources, such as at large fossil fuel plants and industries with major CO2 emissions. Extracting CO2 from the air – Direct Air Capture (DAC) – is possible, but its lower concentrations in the air poses significant engineering challenges.

Carbon dioxide can also be utilised in a process known as “enhanced oil recovery” (EOR) –  injecting CO2 in depleted oil fields to produce incremental barrels of oil. Enhanced oil recovery is not a new process and has been in commercial use for the last 40 years.

The US Department of Energy said in a statement, “While we’re safely and permanently storing large quantities of CO2 underground, we’re also working on beneficial CO2 utilization. Enhanced oil recovery is one important pathway.”

Though some CO2 resurfaces with the oil, it is captured, separated, and pumped right back into the oil reservoir. In practice, around 90 – 95% of the CO2 used in enhanced oil recovery ends up underground, which is why the industry needs a steady supply of CO2  – to continue recovering oil through EOR.

Beyond utilising carbon for EOR, researchers are looking to convert CO2 in to products, which some foresee as a trillion-dollar market that will capture billions of tons of CO2.

A Canadian startup has converted CO2 into nanoparticles used for concrete. Researchers in Bangalore, India aim to convert CO2 into methanol, used to make resins, pharmaceuticals, perfumes and more. Meanwhile, a California-based startup is capturing CO2 for the production of bioplastics, in a collaboration with the furniture giant IKEA.

Many of these innovations are still in the early stages of development.

Reframing Carbon as an “Asset” and Driver of Economic Growth

In the report Making Carbon a Commodity, the authors suggest that carbon is an economic commodity that could add $190 billion to US GDP by 2040 and create 780, 000 jobs through enhanced oil recovery.

89 billion barrels of additional oil are trapped in onshore reservoirs, the US Department of Energy estimates – in stark contrast to the country’s current proven domestic reserves of 21.9 billion barrels.

Enhanced oil recovery methods can tap in to this production, according to the Department, increasing the country’s oil recovery from approximately 30% to 60%.

Carbon capture can be an attractive option for developing countries that face conflicting priorities in balancing energy needs and emissions reductions.

China is the perfect testing ground for large-scale deployment of carbon capture technology, experts say. The country is developing their own CCUS technology and has 9 carbon-capture projects in pilot stage.

As the world’s top energy consumer and COemitter accounting for 30% of global emissions, China not only needs carbon capture, but is well-equipped to implement its mass-scale deployment with heavy-handed governments and state-owned enterprises.

Sinopec, one of China’s largest oil and gas companies, uses enhanced oil recovery on Shengli oilfield, located in the Yellow River delta in Shandong province. Shengli is the second-largest oilfield in China and became depleted after peak production in the 1990s.

By capturing CO2 and pumping it in the ground, Sinopec is now increasing the field’s yield, while recovering CO2 from the atmosphere.

In the absence other financial incentives to cut emissions, enhanced oil recovery is a selling point for carbon capture technology. EOR can be effective pathway for China and other developing nations to maximise their own oil production capacity.

Unlocking Funding Opportunities for Carbon Capture Technology

While carbon capture is technologically feasible, it has a Catch-22 type of funding problem.

Without incentives to cut emissions in the form of a tax credits or carbon dividends, banks are less likely to appraise a carbon-capture project as economically feasible. Yet if the costs of carbon capture were lower, its mass deployment could be profitable.

CURC and Clearpath Foundation advocate for the increase in use of public-private partnerships (PPPs) to develop and scale up early-stage carbon capture technologies, addressing the major challenge of carbon capture: the large capital investment required.

The US Department of Energy could play a crucial role in funding PPPs, as it did in the case of the Petra Nova plant in Texas, the first and only carbon-capture unit in the US installed on a coal-fired power plant. The Department oversees federal efforts to advance the deployment of CCUS technology and is an important proponent of carbon capture R&D and financing.

Shifting the public’ awareness of carbon capture is also important for its roll-out. “CCS doesn’t make anything new… People don’t tend to see it as something additive; they tend to see it as something subtractive.”, says CCS expert Julio Friedmann. “That’s why people tend to look at it as a cost, as opposed to an investment. That needs to change.”

About the Author /

Earth.Org is a global non-profit environmental organisation with headquarters in Hong Kong, raising awareness about biodiversity loss and the deteriorating conditions of natural ecosystems worldwide. Our purpose is to inform, educate and advocate for a more sustainable world. Our mission is to make the true impacts of human activity on our planet, better and more widely understood by policy makers. To encourage policies that eliminate destructive emissions by imposing a market price to correct the gargantuan market failure of excess pollution being produced by modern economic activities. To highlight the true economic and social costs of current over exploitation by humans of natural capital and bio-services for current and future generations. To demonstrate that palatable economic policies exist – that can most rapidly and effectively curb most if not all of the most destructive of current economic and social activities and that will encourage sustainable development. We advocate for better governance of natural resources and campaigns for countries to adopt principles of natural capital accountancy into their economic policy making decisions. To this aim, we bring the latest environmental news to a wider population, always in the context of where in the timeline we are now, and where our current pathway will likely take us. We use data science to extract insights from static and satellite data to form the basis of powerful arguments with data visualisations that better communicate just how far along the destructive pathway we have found ourselves. Earth.Org aims to stir action. Urgent affirmative action. The time is 2020. We, as humans, must change our ways and fast.
