“The goal of our partnership with GTI is to create a next-generation CO2 capture system that is smaller and cheaper than anything that exists today,” Chief Technology Officer of CCSL tells gasworld as he discusses the recent $2.9m DoE funding the GTI and CCSL partnership recently recieved.
As the popularity of carbon capture technology is increasing, companies are required to keep up with the growing market, keeping developments successful and affordable. The carbon capture market recently saw a partnership develop between Carbon Clean Solutions Limited (CCSL) and Gas Technology Institute (GTI), key players in the carbon capture technology industry. The partnership received $2.9m of DoE funding in January (2019) to develop and test its potentially transformative carbon capture technology.
gasworld spoke to Prateek Bumb, Chief Technology Officer of CCSL to gain an insight into the game-changing partnership, and the technology under development. GTI and CCS-US (the US subsidiary of CCSL) are now set to design, build, and test a prototype demonstration unit at GTI’s Des Plaines, Illinois headquarters.
“Both GTI and CCSL see the potential for carbon capture technology to decarbonise fossil fuels, but recognise that its cost prevents it from entering mainstream use. We knew that what was needed was scalable, commercial technologies,” Bumb told gasworld.
“We came together to develop and test technologies for low-cost carbon capture systems that are more efficient and provide more profitable carbon capture than what is currently on the market.”
The partnership is set to showcase its innovations at its Des Plaines headquarters. The demonstration unit will test CCSL and GTI’s ROTA-CAP technology, which works by using novel rotating packed beds to intensify the carbon capture process.
“Our new carbon capture technology, known as ROTA-CAP, is designed so that CCSL’s intensified solvents are pumped into the centre of a rotating cylinder. The centrifugal force from the rotation pushes the liquid outward through a membrane, known as a packed bed gas-liquid contactor,” Bumb told gasworld.
“Next, the CO2 flows from the exterior of the cylinder against the flow of solvent. ROTA-CAP uses the centrifugal force from the rotating horizontal packaged beds to affect the gas-to-liquid contact; the higher g-forces allowed by the rotation improves the mass transfer of the operation and enables smaller units to be used.”
The demonstration unit features the technology on a smaller scale before the company upscales for commercial use.
“The prototype is ten times smaller than current devices and captures one tonne of CO2 per day. We’re researching how well our technology can extract CO2 from synthesis smoke, as well as smoke from industrial gases,” said Bumb.
“These crucial steps will look to optimise the carbon capture process ahead of long-term testing with coal-fired flue gas at the National Carbon Capture Centre (NCCC),” Bumb continued.
The collaboration recognises that the cost of carbon capture is holding the technology back, therefore it is key the partnership masters this factor during their 30-month joint project.
“The US DoE’s current cost estimate for the price of carbon capture is currently around $50 per tonne. Their aim over the coming years is to reduce this to $40 per tonne in the 2020-2025 timeframe. We aim to do even better.”
“At present, we are capturing CO2 at a cost of just $40 per tonne. This 30-month project will reduce it to $30 per tonne or even less, well within the timeframe of the DoE’s target,” Bumb told gasworld.
Carbon capture technologies extract pure CO2 from emissions released by industry, typically achieved by passing smoke through a reactor containing a catalyst that separates the CO2. The captured CO2 can then be stored underground, or converted into products, reducing the impact CO2 emissions have on the environment.
“The goal of our partnership with GTI is to create a next-generation CO2 capture system that is smaller and cheaper than anything that exists today.”
The project spans a 30-month period in total, but CCSL anticipates that the construction of its fully operational demonstration unit will be complete by mid-2019.
“We’re pleased to be working with great partners on this project and are looking forward to seeing the results,” Bumb concluded.
