Carbon seize and sequestration in all of its varied ineffective, inefficient and costly types is having one other run up the hype cycle. Nothing has actually modified. The issues nonetheless exist. The alternate options are nonetheless higher. The potential to be used remains to be minuscule. And so, the CCS Redux collection, republishing previous CCS articles with minor edits.

Lately [in 2019], a agency known as Carbon Engineering obtained $68 million in funding from a trio of fossil gas majors for its air carbon seize answer. This triggered a five-part CleanTechnica collection on Carbon Engineering, its method, and why it isn’t a critical reply to world warming. The method of researching the collection and discussions round it raised the query of what the overall world funding in carbon seize and sequestration has gained us. The reply is grim, however there’s an important information story that emerges from the sooty ashes of carbon seize.

Wind & Photo voltaic Are Displacing Roughly 35 Instances As A lot CO2 Each 12 months As The Full World Historical past Of CCS

The primary piece of the puzzle is simply determining how a lot has been spent on carbon seize schemes globally. There aren’t good sources publicly out there on this level, however there are a number of press releases for main investments. The place there was clearly work being executed however not greenback values, some extrapolation was required, so the numbers for China and the Center East are approximations. These are solely capital prices with no working prices and they’re shifting thousands and thousands of tons round, so the working prices are non-trivial and in addition unreported in simply out there sources. The vast majority of that cash has been spent previously decade.

The build-up will get shut sufficient to $7.5 billion to spherical up for the needs of the evaluation.

There’s a world group with some 40 workers dedicated to reporting on carbon seize and producing glowing experiences of its successes, the World CCS Institute. It claims to be “a world local weather change organisation whose mission is to speed up the deployment of CCS as an crucial expertise in tackling local weather change and offering vitality safety.” A overview of its membership finds lots of a fossil gas majors, and the vitality safety declare is an fascinating add-on to its mandate. It appears extra like a PR arm of the fossil gas trade, particularly after reviewing world carbon seize outcomes.

Maybe unsurprisingly, the World CCS Institute works actually arduous to keep away from speaking even concerning the capital prices. Its experiences discuss concerning the nice work being executed to scale back prices with out truly, you understand, specifying how a lot cash has been spent vs how a lot carbon has been sequestered.

The World CCS Institute maintains a database of ‘massive’-scale carbon seize amenities. It principally doesn’t monitor precise sequestration however merely annual potential. The ‘massive’ is in quotes as a result of there are solely 19 of them and solely three of them exceed one million tons a yr. The dimensions of the issue is in gigatons, so when there are a complete of three amenities greater than 4 orders of magnitude too small, calling the set massive is at greatest relative and in actuality a misnomer. It was essential to extract the info and extrapolate potential web sequestration.

Solely Norway appears to be critical, and it’s nonetheless at a fairly trivial stage. Its Sleipner and Snøhvit CO2 Storage amenities have been working for 1–2 a long time and have sequestered about 30 million tons of CO2.

The following a part of the evaluation was assessing what the carbon avoidance worth of spending the identical cash on wind technology as an alternative. Two approaches have been taken. The primary was a 1-decade view as the vast majority of funding was spent then. The second was a 5-decade view aligning wind investments to when carbon seize amenities got here on line.

As soon as once more, the carbon seize approaches have been handled generously. The last decade noticed roughly 22 million tons of CO2 sequestered by amenities that turned operational. Each CCS facility was thought of to attain most annual outcomes for every of the years of the last decade they have been energetic though few of them have achieved that, with Boundary Dam in Canada as one instance unintentionally working at 40% for a yr with out anybody noticing. In at the least one case, the method counts most of a yr for CCS when it got here in throughout November of the yr. The one hardships imposed on CCS have been an correct accounting for the share truly sequestered when it’s getting used for EOR and exclusion of historic seize amenities within the 10-year view, however that’s addressed within the 50-year view.

The wind technology was restricted to onshore websites. Barely stale metrics for the capital value of wind vitality ($2 million per MW) have been used. Wind technology was assumed to be in common wind regimes versus the Nice Plains of the USA in order that their capability components have been solely 40%. The expenditure was loaded extra to latest than previous. The prevented fossil gas technology was assumed to be 1:1 per MWh, however assumed for the primary reduce to be a fair mixture of coal and fuel technology for 0.8 tons per MWh of emissions. Carbon seize is being given each alternative to indicate its worth with these constraints.

Below these beneficiant situations, if $7.5 billion had been spent on wind vitality as an alternative of CCS over the previous decade, about 50% extra CO2 would have been prevented than spending the identical cash on sequestration. About 33 million tons of CO2 wouldn’t have been emitted by fossil gas sources whereas about 22 million tons have been sequestered by newer schemes.

If the prevented technology was all coal with its 1.1 tons of CO2 per MWh, then the prevented CO2 can be within the vary of fifty million tons of CO2. If it have been changing coal and fuel based on their percentages of 38.3% and 23.1% of worldwide technology respectively, then the avoidance can be within the vary of 40 million tons.

This excludes the long-running (and fairly low cost) Norwegian approaches as they’re exterior of the restrict, and long-term enhanced oil restoration feeds such because the US Shute Creek Gasoline Processing Plant which has been pumping out CO2 for enhanced oil restoration since 1986.

To keep away from excluding massive sequestration schemes, the 50-year perspective is helpful, spending roughly equal quantities of capital on wind farms as an alternative of sequestration in annually a significant CCS facility got here on line, beginning with 1972. Once more the amenities have been assumed to be working at most sequestration annually, the undoubtedly greater operational prices have been ignored and nil leakage within the course of together with within the long-term retailer was assumed. For the wind technology, the capability issue for older wind farms was dropped from the 40% used within the preliminary mannequin to 30%. The desk is just too massive to incorporate, so outcomes can be summarized. If anybody needs to take a look at the underlying knowledge intimately, it’s out there.

If wind technology had been constructed annually as an alternative of the assorted CCS schemes, roughly 122 million tons of CO2 would have been prevented as an alternative of the very beneficiant 85 million tons the schemes managed. That’s 37 million tons or 43% extra. Frankly, it was shocking to see that even underneath beneficiant remedy carbon seize achieved this a lot.

If the prevented technology was all coal with its 1.1 tons of CO2 per MWh, then the prevented CO2 can be within the vary of 170 million tons of CO2, double the very best case state of affairs for CCS. If it have been changing coal and fuel based on their percentages of 38.3% and 23.1% of worldwide technology respectively, then the avoidance can be within the vary of 130 million tons, over 50% higher.

One other piece of context: World oil and fuel revenues have been about $2 trillion in 2017 alone. They’ve managed to get governments to shell out for lots of the carbon seize prices. Let’s assume they managed 25% protection to be, but once more, overly beneficiant. The $7.5 billion at 75% over 10 years turns into about $600 million a yr. A bit of math tells us that CCS is consuming at greatest 0.03% of the annual budgets of oil and fuel globally. Apparently, that’s about precisely the quantity that three oil and fuel majors ‘invested’ within the Carbon Engineering direct air seize firm just lately.

Does that look critical? Or does that seem like PR {dollars} for social license to proceed to pump oil?

Proper now there’s roughly 600 GW of wind technology capability globally. It’s displacing about 1,800 million tons of CO2 yearly, about 22 instances as a lot as the very best case world whole state of affairs for CCS. There may be one other 400 GW of utility-scale photo voltaic capability, which is displacing roughly one other 1,200 million tons of CO2 yearly. Wind and photo voltaic are displacing between them roughly 35 instances as a lot CO2 yearly as the entire world historical past of CCS.

We’re seeing about 100 GW of latest wind and photo voltaic capability yearly around the globe. That 100 GW of capability will displace roughly 300 million tons yearly for its lifetime. Given the roughly 30-year lifespan, annually we’re constructing wind and photo voltaic capability that can displace roughly 9,000 million tons of CO2, over 100 instances the overall world carbon seize historical past. And as soon as once more, the operational and upkeep prices of wind and photo voltaic are a fraction of the CCS approaches.

CCS is a rounding error in world warming mitigation. It’s arduous to see the way it might presumably be extra. And it brings into stark reduction the unlucky actuality that the IPCC relies upon far an excessive amount of on carbon seize and sequestration approaches when it comes to coping with world warming.
