Monetizing carbon capture, transport and storage

At the time of this publication, Gulf Energy Information’s Global Energy Infrastructure (GEI) database was tracking more than 440 active carbon capture projects around the world. These projects include carbon capture projects, hubs and storage facilities. An alternative market for the captured carbon and subsequent credits are the commitments by companies to reduce overall emissions, or even achieve net-zero operations. Such a company may choose to purchase CO2 removal credits to offset their emissions. These credits can be generated and sold by capturing emitted carbon and permanent sequestration. For either system to work, a digital trail must be accurate for companies to buy and sell carbon, as explained in this work.
