Steps for carbon capture engineering projects (Author) The projects typically follow the steps depicted here. Large engineering projects such as carbon capture plants take time to secure. They do have over 50,000 hours of testing under their belts in Norway, Germany, Scotland, and the USA. They claim that their solvent is more robust and less energy intensive than alternatives. That steam is most almost always provided by some sort of combustion.Īker's solvent is the result of 8 years of R&D into different solvent mixtures. Most of the time, the energy used to run an amine process comes in the form of steam that could be otherwise be used to do work such as generating electricity. The gaseous CO2 must then be compressed to high pressure before it is put in a pipeline for transportation.Ībsorption-based technologies use steam to provide the necessary heat to break the CO2-amine bond, so the CO2 can be released. The regenerated water-amine mixture is then ready to be cooled back down and put into the absorber unit and pick up more CO2. The CO2 leaves that unit with some water vapor and a very small amount of amine. The water-amine-CO2 mixture is pumped into another tower, called a stripper unit, that heats up the mixture until the chemical bond between the amine and the CO2 breaks and the CO2 is released as a gas. The dissolved amines chemically bind CO2. A gas containing CO2 enters an absorber tower where the gas comes into contact with the water-amine mixture. These systems use amine chemicals that are dissolved into water. Simplified process flow diagram of a generic amine process (Author)Ī high-level flow diagram of the amine system is show here. Aker's technology is similar to the Shell's ( SHEL ) CANSOLV technology in that it utilizes an amine to capture CO2. Aker was also among the first movers in the carbon capture market, and had significant testing runs at commercial scale as early as 2012 at the Technology Centre Mongstad in Norway. It was spun off from Aker Solutions in 2021 and only has a market cap of ~$700M. “We aim to site our facilities in areas burdened by the fossil fuel industry, to revitalize lands and communities with high-paying, future-proof green jobs.Aker Carbon Capture ( OTCPK:AKCCF) is the only pure-play carbon capture company. “Carbon dioxide removal has the ability to reverse the burden climate change has placed on the world’s most vulnerable populations,” Dennett says. Heirloom announced a $53 million Series A earlier this year, reported to be among the largest investments in new carbon removal technologies. Heirloom has reportedly conducted many tests and prototypes to validate its direct air capture technology results are available in a whitepaper. Other customers include Stripe, Klarna and Shopify. But they’re already selling carbon removal credits, to large clients like Microsoft. Heirloom says more details about the location of its first commercial site in 2023 are coming soon. At the end of limestone's life in our facility, it can be upcycled and used as a feedstock for paper, water treatment or agriculture because it remains chemically unchanged by our process.” “To remove 1 billion tons of CO2 per year from the atmosphere, we estimate we will use 0.15% of the limestone that is currently used just for construction purposes today. And Heirloom welcomes partners and pioneers.Ī key differentiator for Heirloom, Dennett says, is that it has one of the few permanent carbon dioxide removal technologies capable of scaling to remove billions of tons of CO2 from the atmosphere. An illustration of Heirloom's process HeirloomĪlmost like limestone, there are a lot of carbon removal technologies out there. ![]()
