Patent Landscape Analysis in Carbon Dioxide Capture Technologies

Abstract

CO₂ sequestration is the process of capturing, transporting and storing CO₂ from major emission sources. Alarming levels of CO₂ in atmosphere are responsible for creating huge climate change and risks like global warming. To reduce CO₂ and other greenhouse levels, world should shift to renewable resources. The Paris Agreement sets goal of reducing increase in temperature of earth which could be achieved by capturing and storage of CO₂ in parallel of reducing use of fossil fuels for industries. The CO₂ capturing methods are pre-combustion, post-combustion, etc., and storage sites are geological, ocean storage, industrial uses, etc. This chapter presents patent landscape analysis of CO₂ capture technologies. Analysis includes patents filed in the field of carbon capture technologies worldwide and their geographical distribution, top countries, top assignees and top inventors in the world and India. It further discusses categorization of patents based on technology domain, commercialized products worldwide and Indian scenario.
