Hot potassium carbonate CCS: energy economics?
Hot potassium carbonate is a post-combustion CCS technology that bypasses the degradation issues of amines, and can help to decarbonize power, BECCS and cement plants. We think costs are around $100/ton and energy penalties are 30-50%. Potassium carbonate CCS can be stress-tested in this data-file, across 50 inputs.

Global CCS Projects Database
Over 400 CCS projects are tracked in our global CCS projects database. The average project is 2MTpa in size, with capex of $600/Tpa, underpinning over 400MTpa of risked global CCS by 2035, up 10x from 2019 levels. The largest CO2 sources are hubs, gas processing, blue hydrogen, gas power and coal power. The most active…

MHI CCS technology: performance, costs and emissions?
MHI has deployed an amine-based CO2 capture technology, in 15 plants globally, going back to 1999. Reboiler duties are around 2.6 GJ/ton on a 10% CO2 feed. Capture rates and capture purity are high. Degradation and amine emissions are controlled, and c80-90% below MEA. CCS costs and complexities remain high. In our view, this is…

Entropy CCS: natural gas CCS breakthrough?
Advantage is a Montney gas producer, which recently sourced a $300M investment from Brookfield to scale up its Entropy23 amine blend for natural-gas CCS. Entropy has captured 90-93% of the CO2 at the first pilot plant at Glacier, Alberta, with 2.4 GJ/ton reboiler duty, 40% below MEA. This 7-page report confirms a moat around the…

Costs of CCS with the amine process?
This data-file models the economics of capturing CO2 from exhaust flues using the amine process. Our base case estimate is informed by five tabs of cost data and technical papers, but all of the input assumptions can be flexed to stress-test costs. Total costs rise exponentially if it is necessary to capture CO2 from more…

Post-combustion CCS: what energy penalties?
A thermal power plant converts 35-45% of the chemical energy in coal, biomass or pellets into electrical energy. So what happens to the other 55-65%? Accessing this waste heat can mean the difference between 20% and 60% energy penalties for post-combustion CCS. This 10-page note explores how much heat can be recaptured.

CCS absorbers: unit sizing and residence times?
Post-combustion CCS plants flow CO2 into an absorber unit, where it will react with a solvent, usually a cocktail of amines. This data-file quantifies operating parameters for CCS absorbers, such as their sizes, residency times, inlet temperatures, structural packings and the implications for retro-fitting CCS at pre-existing power plants.

CANSOLV: CCS amine case study?
CANSOLV is a proprietary CCS amine being commercialized by Shell since 2014. This data-file aggregates data into its reboiler duties (2.4-3.2 GJ/ton), amine emissions to air (can be below 0.2ppm) and degradation rates (pretty decent, especially up to 2,500 hours). Interest in workable CCS amines has been accelerating since early-2023.

Carbon capture and storage: research conclusions?
Carbon capture and storage (CCS) prevents CO2 from entering the atmosphere. Options include the amine process, blue hydrogen, novel combustion technologies and cutting edge sorbents and membranes. Total CCS costs range from $80-130/ton, while blue value chains seem to be accelerating rapidly in the US. This article summarizes the top conclusions from our carbon capture…

CCS: what CO2 purity for transport and disposal?
The minimum CO2 purity for CCS starts at 90%, while a typical CO2 disposal site requires 95%, CO2-EOR requires 96%, CO2 pipelines require 97% and CO2 liquefaction or shipping requires >99%. This data-file aggregates numbers from technical papers and seeks to explain CO2 purity for transport and disposal.
