Carbon capture, utilization, and storage (CCUS) refers to technologies that capture carbon dioxide (CO2) emissions from sources such as power plants, industrial facilities, and transportation, and either store it underground or use it for beneficial purposes. CCUS can play a role in reducing greenhouse gas emissions and mitigating climate change, as CO2 is a major contributor to global warming. In the Baltic Sea region countries (BSR), patent searches from 2000 to 2020 reveal that CCUS technologies are focused on CO2 storage, monitoring, utilization, and transport. However, the adoption and deployment of these technologies has been slow due to a variety of factors, including a lack of government action on climate change, public skepticism, increasing costs, and advances in other options such as renewables and shale gas. Overall, CCUS has the potential to significantly reduce CO2 emissions and contribute to climate change mitigation efforts, but more work is needed to overcome the barriers to its widespread adoption in the BSR and elsewhere. This could include policy measures to incentivize the use of CCUS technologies, public education and outreach efforts to increase understanding and support for CCUS, and research and development to improve the efficiency and cost-effectiveness of these technologies.
Capturing CO2 and preventing it from being released into the atmosphere was first suggested in 1977; using existing technology in new ways. CO2 capture technology has been used since the 1920s for separating CO2 sometimes found in natural gas reservoirs from the saleable methane gas. More recently, investment in CCS is being driven by the oil and gas industries as well as cement, iron and steel, and chemical production industries in the push for decarbonization. Once it is separated from other gases, the carbon dioxide is then compressed, transported, and injected underground for permanent storage. About 90-100 % of produced carbon dioxide can be captured in this manner. Many are betting on CCS as a key to greenhouse gas emission reductions, since leveraging CCS is expected to achieve 14-19 % of the reductions needed by 2050 (1,2,3). In 2020, we sent 40 billion metric tons (t) of carbon dioxide into Earth’s atmosphere. We need to cut that number to 0 by 2050 if we are to avoid the worst consequences of climate change, according to the Intergovernmental Panel on Climate Change (IPCC). The objectives of this paper is to present the patent landscape of Baltic sea region countries (BSR), which includes Lithuania, Latvia, Estonia, Finland, Denmark, Sweden, Russia, Poland and Norway. To perform the analysis searches have been conducted to identify patents related to Carbon capture and sequestration for the BSR. Patent analytics searches have been restricted to dates from 2000-2020. Technologies investigated mainly focuses on CO2 storage, monitoring, utilization and transport.The patent analytics searches have been conducted to identify patents related to CCUS technology. The search resulted in 3299 patent families. A relevancy analysis was done to identify patents which are related to CCUS & resulted in 497 patent families. Identified relevant patents have been categorized in a classification scheme. Results of this patent analytics work shows that in 2009 we have the greatest number of IP activity for CCUS. Exponential growth in patent filing since 2005-2009, showing an increasing trend for CCUS activities, 2010-2015 has an exponential decreasing trend for CCUS activities. In northern and eastern Europe, Russia & Poland are leading the research & patent filing in the CCUS domain. From industry point of view General Electrics (GE)has the highest number of publications followed by Mitsubishi and Siemens. 85 % of 497 relevant Patent families are Alive. GE has around 78 % of its families alive. The top patents are related to capture, storage, sequestration or disposal of greenhouse gases and followed by patents related to separation processes. CO2 capture is the most explored technology/CCUS type along with storage. Unfortunately, there is a decreasing trend in patent filings since 2016. The CCUS technologies are striving to gain traction in the set of options for dealing with climate change, but growth is very slow due to absence or low intervention of government action on climate change, public scepticism, increasing costs, and advances in other options including renewables and shale gas.
Baltic Carbon Forum (BCF) is an annual event sponsored by Nordic Council of Ministers through Nordic Energy Research through their network BASRECCS. BCF 2022 was held on 13th and 14th Oct. in Kaunas, Lithuania. The aim of the BCF 2022 was to enable interested and engaged stakeholders to meet, discuss, share knowledge and experiences, and develop projects. BCF also aims to increase awareness about Carbon Capture Utilization and Storage (CCUS) among younger generations with aim of securing a sustainable future for all. The BCF2022 invited a number of academic and industry experts from the Baltic Sea region countries, which included policymakers, financial institutes, industry representatives and academics for sharing their experiences, conduct discussions and brainstorming sessions to identify gaps with aim of expediting the deployment of a large-scale CC(U)S project in the Baltic Sea Region (BSR). BCF 2022 was attended by 74 participants. There were 38 participants who attended the conference onsite and 36 participants attended the conference online. Participants came form 15 countries, which included Finland, Lithuania, Hungary, Sweden, Poland, Norway, Estonia, Denmark, Latvia, Belgium, Germany, USA, UK, India and South Africa. This paper presents a short summary of all the talks presented at the BCF 2022 conference [1, 2].
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
