It captures carbon by blowing air through towers containing a liquid hydroxide solution. CE launched its first pilot plant in 2015. The company was created in 2009 by Harvard professor David Keith an academic at Harvard University specializing in geoengineering. Top Direct Air Capture Technology Companies Carbon EngineeringĬarbon Engineering (CE) is a Canadian company that has plants located in Squamish, British Columbia, and Houston, Texas. At the wells, the liquid CO2 is injected more than two kilometers underground. The CO2 is then separated from the amine and pressurized to turn the captured CO2 gas into a liquid that is transported by pipeline 65 kilometers through well sites. The process requires hydrogen, and it captures CO2 with a product called amine. Their facility is called Scotford upgrader and it turns tar sands bitumen into synthetic crude for fuel. The Quest carbon capture and storage (CCS) facility sequesters CO2 as a byproduct of its fossil fuel refining process. The net result is an emissions-free process that can generate electricity on a large scale (Rathi, 2018 Ryan, 2019). The carbon that isn’t reused is captured and can then be used or injected underground, where it’s permanently absorbed by rock. The mixture that exits the turbine is separated and the CO2 is recycled, compressed, and put back into the chamber. It works by using a turbine, it burns natural gas and pure oxygen which in combination with heat and high pressure turns a shaft to generate electricity. This a process for converting fossil fuels into mechanical power, while capturing the generated carbon dioxide and water. Net Power’s patented thermodynamic cycle is known as the Allam cycle (aka the Allam power cycle). Net Power makes emissions-free energy and this is significant because electricity generation is responsible for 40% of the world’s annual greenhouse gas emissions (Ryan, 2019). Top Carbon Capture Technology Companies Net Power Net Power and Quest stand apart because of their association with fossil fuels. All have functional plants, and all are modular (Rathi, 2017). Carbon Engineering uses a liquid system, with calcium oxide and water. The CO2 that is captured by these technologies can be injected underground or used to manufacture anything from plastic to fuel.Ĭlimeworks and Global Thermostat have piloted systems in which they coat plastics and ceramics, respectively, with an amine, a type of chemical that can absorb CO2. They are proofs of concept which have demonstrated their viability. “These guys actually have something you can measure,” said Princeton’s Pacala (Service, 2018). These companies were selected based on the fact that they all have generated enough data to warrant further scrutiny. These are the most well-established pilot projects and commercial demonstration plants in the world. Net Power and Quest are top companies with carbon capture and storage (CCS) technologies while the other four are working examples of carbon removal technologies. In previous articles, I have explored why we need to siphon carbon dioxide out of the atmosphere, assessed carbon capture technologies, and reviewed the cost and scalability of these technologies. Here are six of the best carbon capture and carbon removal companies for negative emissions technology: Net Power, Quest, Carbon Engineering, Global Thermostat, Climeworks, and Carbfix. The Biden administration’s support for carbon capture and carbon removal technology is contributing to growing interest in companies working in this space.
