Without carbon capture, the worldwide fleet of coal and gas power plants would need to retire about 23 and 17 years earlier than expected lifetimes, respectively, in order to limit global warming to 1.5 and 2 degrees celsius .
That’s what Session 6 attendees heard this afternoon at the gasworld CO2 Summit in Chicago when Andrew Baxter, CEO and President of Sustainable Energy Solutions, a Chart Company, took to the stage to highlight the firm’s Cryogenic Carbon Capture™ technology.
“It is the lowest cost and lowest energy retrofit technology that we’re aware of,” Baxter told delegates. “It is also the easiest retrofit carbon capture technology as we know it,” he continued.
Particularly recognised for some ground-breaking properties, Baxter said, “CCC is the lowest cost and lowest energy retrofit technology that we’re aware of. It is also the easiest retrofit carbon capture technology as we know it,” he continued.
So how does it work? Baxter explained the whole process in just four simple steps:
1. Flue gas is cooled
2. CO2 is separated as a solid from the light gases
3. CO2 is melted and prepared for transport
4. Light gases are re-heated and released into the atmosphere
CO2 Recovery and Applications in Carbon-Negative Setups
“Higher CO2 concentration in environmentally friends and market competitive sources are becoming available,” Alfonso Peschiera, Global Product Manager for High Pressure Gases and Service, told delegates and he placed environmentally friendly CO2 sources in the spotlight during his presentation.
“In the past two or three years, there has been a great drive to start retrofitting plants to take advantage of CO2 produced by the plant itself.”
“If we manage to recover the CO2 in this application, we can consider the plant carbon negative. As long as the CO2 isn’t released into the atmosphere in any way – and there are a lot of tax credits and incentives in place to help people make this move.”
Looking at biogas as a source for CO2, Peschiera highlighted transportation as a headwind. “Transporting the CO2 is one of the key issues when it comes from biogas plant,” he said.
Biogas upgrading with CO2 capture and liquefaction system for greenhouses and the food and beverage industry was in focus when Peschiera highlighted the above. This process is often witnessed in Europe and many are already witnessing considerable advantages of doing this, especially as shortage and supply chains continue to cause concerns.
CO2 capture in the cement industry was also highlighted by Peschiera. “By each tonne of cement that is produced at a plant, we have the potential to produce 0.5-0.8 tonnes of CO2 that can be captured and then utilised,” he explained.
“We see large potential for negative CO2 emission in cement plants and compression is a really big part of this. Companies will need some sort of flue gas compressor, a CO2 separation unit and some way to compress or transport the CO2 afterwards.”
“In Europe, we are seeing a lot of incentives from companies that is supporting the use of these technologies in the cement market,” he concluded.
Disrupting Commercial Supply: Innovation, Incentivisation and Impact
“Where you get your CO2 from today won’t be where you get it from tomorrow. Who you get your CO2 from today, won’t be who you get it from tomorrow. What you pay for CO2 today, won’t be what you pay for CO2 tomorrow.”
Those were three predictions put forward by Jeff Holyoak, Vice-President of Sales and Market Development at TOMCO Systems, as he today closed Session 6 at the gasworld CO2 Summit here in Chicago.
When Holyoak says tomorrow, he means in three to four years’ time, as the market, supply, demand and technology continue to change, and new technologies continue to evolve.
With this, he explained that traditional sources of CO2 could greatly diminish. 45Q is going to make traditional CO2 sources diminish – and if these sources do disappear, a whole lot of issues are going to bulldoze the industry.
“Where we get our CO2 today, probably won’t be there for several years,” he told re-enforced to delegates as he highlighted how changes to current domes, pipelines and plants could heavily impact the market.
Adding to that, Holyoak continued, “CO2 may not be the cheap, abundant gas that I it today and $85 per tonne could be the new baseline price. The price [of CO2] will go up in the future.”
“All of these factors are going to ultimately impact our future of CO2. So, we as an industry need to continue to innovate. The pain is short term, right now, but the industry needs to be ready for the future state.”
“The industry needs to change the way it thinks about CO2. We need to find new and innovative ways to use CO2. We need more applications and think what more we can do with produced CO2. Let us find constructive uses for it,” Holyoak concluded.
Sessions at gasworld’s CO2 Summit have now concluded, but the coverage doesn’t stop there! Make sure to keep an eye out for more written coverage, video content and social media posts in the coming days and weeks as we continue to place CO2 at the heart of discussion and debate.
Summit attendees are invited to join the gasworld team for an Event Dinner and Farewell this evening, sponsored by Cold Jet, to reflect on a full day of topical content.
