The document outlines the three-stage process of carbon capture and storage (CCS)—capture, transport, and storage—and explains why Louisiana is well-suited for this technology due to its industrial base and subsurface geology. It highlights that CCS could create 17,000 new jobs and attract $76 billion in investment, while also reducing air pollutants like particulate matter and sulfur oxides. The text details the geologic mechanisms that ensure permanent CO2 storage and describes the EPA's Class VI regulatory program, which governs well construction, monitoring, and financial responsibility to protect groundwater and the public.

Poland is the EU's third-largest emitter, with industrial point source fossil emissions totaling 40.6 MtCO2/year. The document argues that CCS is essential for the decarbonisation of energy-intensive industries—particularly cement, steel, and fertilizer—and for providing firm power in a decarbonised energy grid. Poland possesses a significant CO2 storage potential of over 15 Gt, primarily in saline aquifers (14.3 Gt) and hydrocarbon fields (1 Gt), which could store 369 years of its annual industrial point source fossil emissions. Current projects like GO4ECOPLANET aim to decarbonise cement production at the Kujawy plant, with CO2 transported to the North Sea via the ECO2CEE project. The document highlights that developing domestic onshore storage and pipeline infrastructure could reduce transport and storage costs from €93-€100/t to between €23-€49/t. To accelerate deployment, the author recommends developing national storage resources, supporting projects to Final Investment Decision (FID) through mechanisms like carbon contracts for difference, and establishing cross-border partnerships with other EU Member States and Baltic countries.

Portugal has a theoretical CO2 storage capacity of 7.09 GtCO2, which could support the decarbonisation of its energy-intensive industries, particularly cement and pulp and paper. While no active CCS projects exist, the STRATEGY CCUS project has identified the Lusitanian Basin as a key area for cluster development. To accelerate adoption, the document recommends creating a national carbon management strategy, clarifying offshore maritime space permits, and establishing cross-border storage partnerships with EU member states like Spain.

The document argues that carbon dioxide removal (CDR) is essential to counterbalance residual emissions to limit global warming to 1.5°C, requiring 20-660 gigatons of net negative CO2 emissions until 2100. It emphasizes the need for high-quality certification to ensure environmental protection and reliability, highlighting the EU's proposed Certification Framework for Carbon Removals (CRCF) as a regulatory tool to monitor, report, verify, and certify removal activities across three categories: permanent carbon storage, carbon farming, and carbon storage in products.

The document examines the energy transition in Central and Eastern Europe (CEE), highlighting the region's shift away from Russian energy dependence toward a diversified 'all-of-the-above' approach. It identifies significant potential for the region to lead in clean tech manufacturing and innovation, particularly in batteries, small modular reactors (SMRs), and carbon capture, while leveraging the EU's Just Transition Fund to reskill coal workers and build innovation hubs.

The document outlines a technical practice to reduce methane emissions by routing casing gas, which is typically vented to the atmosphere, into a vapor recovery unit (VRU). This method is applicable to oil and gas wells produced via tubing with no packer. One partner, Marathon Oil Company, reported recovering an average of 7,300 thousand cubic feet of methane gas per year, equivalent to 10,000 thousand cubic feet of natural gas with 73% methane content. The economic analysis indicates that the investment can be recovered quickly, with potential investment costs ranging from under $1,000 to over $10,000 and payback periods between 0 and 10 years. For a single well, the recovered gas can offset pipeline costs and electricity expenses, such as an estimated $3,400 annual increase in electricity costs at a rate of 7.5 cents/kWh to inject gas into a 100 psig pressure system.

The document outlines a Partner Reported Opportunity (PRO) for reducing methane emissions by installing downhole separator pumps. These devices separate gas from water within the well, allowing water to be reinjected into lower reservoirs and reducing the volume of methane-laden water sent to surface storage tanks, where emissions typically occur. The technology is most suitable for gas wells with low solids and liquid hydrocarbon production. Reported annual methane savings range from 150 to 750 thousand cubic feet, with a specific example showing 400 thousand cubic feet saved per year for a tank with a daily gas production of 100 thousand cubic feet. While methane reduction is a secondary benefit, the primary economic advantage is the reduction of operational costs for treating or reinjecting produced water. Investment costs vary from under $1,000 to over $10,000, with payback periods ranging from 0 to 10 years.

The document outlines the installation of ejectors—Venturi nozzles that use high-pressure gas to draw in low-pressure sources—to prevent methane venting during equipment maintenance in production, processing, and transmission/distribution sectors. It highlights a partner report where one installation saved 8 million cubic feet of methane over 55 months and provides an economic analysis showing potential annual savings of 700 thousand cubic feet of methane with a payback period of less than 3 years.

The document outlines a Partner Reported Opportunity (PRO) to install velocity tubing strings in natural gas wells. By reducing the flow cross-sectional area and increasing flow velocity, these strings allow for liquid removal without venting methane to the atmosphere. The practice is most suitable for wells with relatively low liquid production and relatively high reservoir pressure. One reported case showed a methane saving of 4,680 thousand cubic feet per year by eliminating a bi-weekly venting practice that emitted 180 thousand cubic feet per well per event. Investment costs vary from under $1,000 to over $10,000, with payback periods ranging from 0 to over 10 years, typically recovering investment in less than 3 years through increased production and extended well life.

The document outlines a Partner Reported Opportunity (PRO) to reduce methane venting at compressor stations by moving fire gate valves closer to the facility. This relocation reduces the length of the pipeline isolated from the facility, thereby decreasing the volume of gas released through Emergency Shutdown (ESD) systems. One partner reported reducing methane emissions by nearly 7.1 million cubic feet within one year across three facilities. The economic analysis suggests that for a 24-inch pipeline with a 2,000-foot isolation length at 900 psia operated four times annually, methane savings can reach 1,700 thousand cubic feet per year, with investment costs potentially ranging from under $1,000 to over $10,000 and payback periods between 0 and 10+ years.

The document outlines a Partner Reported Opportunity (PRO) to install pressurized storage tanks for condensate, preventing methane from flashing into the atmosphere when condensate is transferred from high-pressure pipelines to atmospheric tanks. This practice allows for the economic recovery of condensate and associated gases. A partner reported that installing four pressurized tanks saved 27,992 thousand cubic feet of methane annually, with a single 400-barrel tank saving 7,000 thousand cubic feet per year. The primary benefit is the reduction of VOC and HAP emissions, with investment costs reported at $37,500 in 1998 and a payback period of two years through recovered methane revenue.

The document outlines a method to reduce methane emissions by improving maintenance and operational schedules for refrigeration compressors to minimize the number of engine starts. A partner reported reducing restart frequency from 9.4 times per year to once per year, saving 1.1 million cubic feet of methane annually.

The document outlines a practice to reduce methane emissions by increasing the replacement frequency of turbine meter measurement modules from every two years to every three years. This change reduces the number of times pipelines must be blocked and gas vented to the atmosphere for maintenance. A partner reported that for a pipeline with 519 meters, this practice saved 38 thousand cubic feet of methane annually. The primary benefit is identified as the reduction of labor costs, with an estimated annual methane saving of 27 thousand cubic feet for a baseline of 500 meters operating at 900 psig.

The document outlines a methane reduction opportunity (PRO No. 204) involving the replacement of glycol dehydrators with cyclone separators and in-line heaters. In this process, natural gas expands in a cyclone separator to cool and condense water vapor, which is then reheated to a specific dew point. This eliminates the need for glycol, thereby avoiding the methane emissions associated with glycol dehydrator operations. The technology is suitable for transport and distribution systems in cold environments, provided there is sufficient upstream pressure and a power source for resistive heaters. One partner reported saving 1,930 thousand cubic feet of methane by replacing 14 dehydrators. Economic analysis suggests a strong return on investment, with annual methane reductions of 130 thousand cubic feet for a system processing 10 million cubic feet of gas per day (reducing water vapor from 7 to 4 lbs/MMcf).

The document outlines a method to eliminate methane emissions during the testing of pressure relief valves (PRVs) by substituting natural gas with high-pressure nitrogen. A partner report indicates that applying this method to 120 PRVs can reduce methane emissions by 10,000 cubic feet per year, while another case involving 100 valves saved 8,000 cubic feet per year. The primary motivation for using nitrogen is safety, particularly where sour gas is present, with the methane reduction serving as a co-benefit. The practice requires nitrogen cylinders with pressure exceeding the PRV set point and involves minimal additional costs since labor remains constant regardless of the gas used.

The document highlights that superhot rock geothermal could be a transformative energy source for Chad, with preliminary modeling suggesting that just 1% of the country's resource could provide 3,051 GW of energy capacity. While unlikely to meet 2030 climate goals, the technology offers a low-land-footprint alternative to fossil fuels and other renewables, potentially addressing Chad's severe energy poverty where less than 10% of the population has electricity access.

The document highlights that just 1% of Chile's superhot rock geothermal resource could provide 1385 GW of energy capacity, potentially meeting the country's projected 2050 electricity demand and replacing all coal and gas imports used for electricity production. It argues that this energy-dense resource would require significantly less land than other energy sources and support Chile's goal of carbon neutrality by 2050.

The document highlights that just 1% of China's superhot rock geothermal resource could provide 10,513 GW of energy capacity, potentially replacing all fossil fuels used for electricity production and reducing carbon emissions by approximately 5,943 megatonnes. It argues that this energy source offers a low land-use footprint, provides reliable 24/7 power, and allows for a transition of the existing oil and gas workforce into the zero-carbon sector.

The document describes Class VI primacy as the authority granted by the EPA to states, territories, or tribes to manage the permitting of carbon dioxide injection wells for carbon capture and sequestration. It outlines the four-phase application process and the ten core requirements a state must meet to prove its program is at least as stringent as federal standards, including site characterization, well construction, and financial responsibility. The text argues that state-led primacy can lead to more efficient permitting and oversight due to better local knowledge of geology and community needs.

The document details the regulatory framework of the EPA's Underground Injection Control (UIC) program, specifically Class VI wells used for carbon capture and storage (CCS). It outlines stringent requirements for site characterization, construction, monitoring, and financial responsibility to protect underground sources of drinking water. As of December 2023, 12 Class VI wells have been permitted in the U.S., with 178 additional applications submitted. The text emphasizes the need for increased funding and state primacy to alleviate permitting bottlenecks and support the rapid expansion of the CCS market driven by the Inflation Reduction Act and the Bipartisan Infrastructure Law.
