The authors emphasize that BECCS cannot be categorically labeled as beneficial or detrimental, as lifecycle impacts vary based on the supply chain and technology used.

The document addresses common concerns and misconceptions regarding carbon capture and storage (CCS), asserting that it is a proven technology essential for reaching net-zero emissions, especially in industries like cement and steel where electrification is insufficient. It highlights Europe's significant storage potential and the role of government funding in scaling the technology.

The document outlines how nuclear energy can support the decarbonisation of EU heavy industries, which account for over half of Europe's energy consumption. It highlights the benefits of nuclear-industrial co-location to provide 24/7 clean firm energy, high-temperature heat for processing, and synthetic fuel production. The text specifically promotes small modular reactors (SMRs) as a flexible solution for industrial clusters, citing planned projects in Poland and Romania. To accelerate this transition, the author recommends streamlined licensing, the formation of regional industrial 'buyers' clubs', and clear policy frameworks that recognise nuclear heat as a valid tool for industrial decarbonisation targets.

The Porthos project is a pioneer CCS initiative designed to transport and store CO2 from the Port of Rotterdam in depleted gas fields under the North Sea. It is presented as a critical component for the Netherlands to meet its target of reducing CO2 emissions by 55% by 2030, as the industrial sector must reduce emissions by 60% in that timeframe. Porthos is expected to provide approximately 17% of the total intended industrial CO2 reduction for 2030 and address 11% of the Port of Rotterdam's emissions. The project's infrastructure is designed for a capacity of 10 Mt CO2 per year, with a projected total storage of 37 million tonnes over 15 years. However, the project's commencement depends on a final decision by the Raad van State regarding nitrogen emission impacts on Natura 2000 areas.

Superhot rock energy involves injecting water into deep, dry rock (above 400°C) to extract thermal energy for power, heat, or fuels. It offers higher energy density than conventional geothermal, with single-well potentials of 35 MW or more compared to 3-5 MW. The Clean Air Task Force (CATF) aims for commercial demonstration this decade, suggesting that $5+ billion in investment over ten years could prove its commercial potential and lead to 'geothermal everywhere' by mid-century.

The document argues that CCS is essential for decarbonising hard-to-abate industrial sectors like cement and steel and for achieving net-negative emissions after 2050. It details the technical process of capturing CO2 using amines or membranes and storing it in saline aquifers or depleted reservoirs at depths exceeding 800 metres. The text asserts that geological storage is permanent and safe, with projected annual leak rates as low as 0.0002% in regulated industries. While costs vary by source—ranging from under 90 euro per tonne for fertilisers to 700 euro for direct air capture—the document suggests that government support for shared infrastructure can drive down costs, similar to the trajectory of offshore wind. It highlights approximately 100 proposed projects in Europe, particularly around the North Sea, and notes that the EU may need to capture 300 to 600 million tonnes of CO2 annually by 2050.

France aims to capture 30-50 Mt of annual CO2 by 2050, focusing on seven key industrial clusters and leveraging a conservative estimated storage resource of 4.8 Gt. The government has launched a national CCUS strategy and provided €5.6 billion for industrial decarbonisation, including 'carbon contracts for difference' for specific CO2 streams. Key projects include the Dkarbonation and GOCO2 initiatives, which focus on export terminals and pipeline infrastructure for hard-to-abate sectors like cement and steel.

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.

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 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 presents nuclear energy as a critical, low-carbon complement to renewables for meeting growing global electricity demand, specifically within Central and Eastern Europe. It highlights the region's existing nuclear infrastructure and the potential for new deployments to achieve EU climate-neutrality goals. The text addresses safety, waste management, and costs, noting that while upfront capital expenditures are high, nuclear power is among the safest and cleanest energy sources available.

The document examines the transition from diesel-powered transit buses to hybrid-electric alternatives, highlighting significant reductions in emissions and fuel consumption. It details the technical differences between series and parallel hybrid configurations and analyzes the financial barriers to adoption, noting that while hybrid buses have a higher purchase price, federal grants and lower operational costs mitigate these expenses. By 2006, over 900 hybrid buses were in service across more than 40 North American transit agencies.

This fact sheet identifies 20 potential sources for hydrogen production and categorizes them by the technical process used to extract or create the gas, ranging from steam methane reforming and gasification to electrolysis and photobiological water splitting.

Direct air capture (DAC) involves scrubbing CO2 from ambient air for underground storage or use in products, requiring low-carbon energy to achieve net carbon removal. The document argues that the U.S. could plausibly remove over 1 gigaton of CO2 by midcentury if commercial deployment begins by 2025 with 20–30 percent annual growth. Achieving this requires a dual policy approach: approximately $150 million in annual public funding for R&D and demonstration over the next decade, and amendments to the 45Q tax credit to incentivize private investment, with estimated tax expenditures rising from $360 million per year by 2025 to $1.3 billion by 2030.
