The document argues that the U.S. coal fleet is already in a sustained economic decline, making the EPA's emissions rules a catalyst for prudent utility planning rather than a source of economic or reliability risk. It asserts that the 2032 compliance timeline is sufficient for utilities to procure replacement resources, citing hundreds of gigawatts of 'shovel-ready' projects in interconnection queues. The authors maintain that 'baseload' coal is no longer necessary for grid stability, as portfolios of wind, solar, battery storage, and low-utilization gas can meet peak loads and growing demand without compromising reliability.

The document argues that hydrogen blending is neither an economical nor an effective way to decarbonize natural gas users, noting that low-concentration blends provide insignificant emissions reductions and high-concentration blends require significant infrastructure upgrades.

The report highlights that EU power system flexibility needs are expected to double by 2030 as renewables are projected to reach 66% of electricity generation. It identifies battery storage and demand side flexibility (DSF) as critical but under-utilised tools to replace fossil fuel backup and reduce renewable curtailment. While battery capacity doubled to 16 GW in 2023, the report notes a significant lack of explicit 2030 targets for storage and DSF in national policy documents. It calls for improved data transparency, the removal of regulatory barriers for distributed energy resources, and the inclusion of flexibility targets in National Energy and Climate Plans (NECPs).

The report identifies 219 facilities in Pennsylvania eligible for 45Q tax credits, emitting 82.5 million metric tons of CO2 annually. While the Lockport and Knox formations offer a theoretical storage capacity of 510 to 1,640 million metric tons, low permeability across most assessed saline aquifers poses a significant challenge to commercial viability. Alternative storage options include depleted oil and gas fields, CO2-enhanced oil recovery (EOR), and the Marcellus and Utica shales, though the latter requires further research.

The study assesses three geofluid scenarios and three power generation models, concluding that an unwashed open cycle plant is the most efficient pathway for superhot rock energy. It identifies a technology gap in steam turbine design, which is rated at TRL 5-6, while other surface equipment is rated TRL 8-9. The report recommends dry cooling (Air-Cooled Condensers) to minimize water consumption and estimates the surface facility capital cost at $1,988.50 USD/kW.

The Clean Air Task Force asserts that including soil organic carbon (SOC) in the GREET model for section 40B SAF tax credit eligibility contradicts the requirement for a methodology similar to CORSIA, which does not credit SOC. The author argues that SOC sequestration is too variable and impermanent to be reliably verified, noting that the Treasury would need to establish complex regional baselines and implement novel claw-back provisions to prevent tax credits from being awarded for emissions reductions that are later reversed.

The briefing outlines a three-pronged strategy to modernize the US power grid to accommodate increasing electricity demand from data centers, manufacturing, and electric vehicles. It advocates for 'Big Wires' (high-voltage transmission and grid-enhancing technologies), 'Small Wires' (distribution upgrades for diffuse loads like EVs), and 'Non-Wires' solutions (virtual power plants) to ensure a reliable and affordable transition to a fully electrified economy.

The document examines the integration of clean electrolytic hydrogen into the U.S. electric system, emphasizing its potential as long-duration energy storage for 'last mile' decarbonization. It analyzes how the design of the Section 45V tax credit—specifically the 'three pillars' of incrementality, temporal matching, and deliverability—will determine whether hydrogen production increases net greenhouse gas emissions or supports grid reliability. The authors warn that without these pillars, electrolysis could drive significant load growth (up to 32% by 2032) and potentially increase emissions. The brief also highlights risks related to NOx emissions, water consumption, and public safety, urging developers to engage early with host communities to ensure an equitable transition.

CATF opposes the UK government's consultation on hydrogen blending into gas networks, stating that low-carbon hydrogen is too scarce and expensive to be used for residential heating or minimal GHG reductions in power generation. They recommend prioritising 'no regrets' industrial sectors, such as refineries and ammonia producers, and using electrolytic hydrogen from curtailed electricity for long-duration energy storage instead of grid injection.

The document asserts that zero-carbon electricity grids are possible and debunks myths regarding the need for fossil fuel backups or the risk of grid overload from renewables. It highlights that wind and solar costs fell by 55% and 85% respectively between 2010 and 2020, and that countries like Denmark, Portugal, and Uruguay are already demonstrating high renewable integration. However, a significant bottleneck exists in grid infrastructure, with 3,000 GW of renewable projects awaiting connection across several major economies. The briefing recommends a cross-sector approach integrating heating, cooling, and industry, alongside investments in digitalisation, storage, and cross-border interconnectors to ensure stability and efficiency.

The report provides a detailed technical overview of refinery processes and establishes four regional refinery archetypes (USA, GCC, Europe, and Singapore) based on median capacities and typical configurations to facilitate future decarbonisation analysis.

Bulgaria is at a pivotal energy transition point as coal's share of electricity generation fell below 30% in 2023. While solar power has grown rapidly, wind energy has stagnated since 2012. The report highlights a technical offshore wind potential of 4.3-5 GW in the maritime exclusive economic zone near Romania, which could lower wholesale power prices by 45% by 2030 if combined with increased onshore wind and better interconnections. To achieve this, the report recommends the swift adoption of a new offshore wind law, the implementation of Contracts-for-Difference (CfDs), and the update of the National Energy and Climate Plan with explicit 2030 targets.

The marine shipping industry, responsible for about 3% of global GHG emissions, is under pressure to decarbonize following new targets from the EU and the IMO. The Clean Air Task Force (CATF) highlights that dual-fuel engines, which can run on conventional fuel as well as alternatives like methanol and ammonia, are becoming a standard design to provide flexibility over a ship's 30-plus-year lifespan. CATF's analysis indicates that ammonia-fueled ships could nearly fully decarbonize at a lower lifetime fuel cost than heavy fuel oil if carbon pricing is in place. To achieve these goals, the document recommends a clean marine fuel standard that mandates minimal upstream emissions, ensures safe bunkering, requires on-board pollution controls for gases like nitrous oxide, and uses economic incentives like a low carbon fuel standard to manage the higher costs of zero-emission fuels.

The report argues that CCS is essential for the EU to reach climate neutrality by 2050, noting that current deployment rates are far below required levels and that no operational CO2 storage sites currently exist within the EU. It recommends setting clear deployment targets for CCS, DACCS, and BECCS, and establishing a strategic plan to distribute storage basins across the region by 2035 to avoid over-reliance on the North Sea. To address financial barriers, the author suggests coordinating funding, using carbon contracts for difference (CfDs), and creating a dedicated tender for capture capacity. The report also emphasizes the need for a common regulatory framework for cross-border CO2 transport, the creation of an aggregation platform to match CO2 sources with sinks, and the development of market demand for near-zero carbon products. Finally, it advocates for the prioritization of permanent industrial carbon removals (DACCS and BECCS) and their gradual integration into compliance markets like the EU ETS, provided robust standards and monitoring are in place.

The document explores the role of advanced bioenergy systems in decarbonizing agriculture, emphasizing a 'carbon-negative circular bioeconomy' that combines emissions reductions with permanent carbon dioxide removal (CDR). It identifies opportunities such as utilizing biogenic point sources, growing perennials on underutilized land, and replacing synthetic nitrogen fertilizers. However, it warns of risks including methane leakage from anaerobic digesters, detrimental land-use changes, and environmental justice concerns. The report argues for policy shifts that prioritize CDR over simple energy production and calls for increased research, development, and demonstration (RD&D) to scale cellulosic bioenergy technologies.

A 2023 longitudinal study of 23 water infrastructure projects in Wajir County, Kenya, found that boreholes are significantly more resilient to climate shocks than water pans, which accounted for all non-functional projects. While community involvement in planning fostered ownership, the study identified critical gaps in technical capacity for maintenance, a lack of climate information during the design phase, and a failure to budget for ongoing monitoring and evaluation.

The report examines the rise of 'algorithmic warfare,' characterized by the fusion of AI with small satellites, robotic systems, and mobile devices. It analyzes how AI enhances the OODA loop (Observe, Orient, Decide, Act) and situational awareness while warning of critical vulnerabilities such as 'brittleness,' lack of explainability, and the risks of relying on private-sector partnerships. The authors argue that ethical AI deployment is not only a moral necessity but a strategic advantage.

The report argues that China's industrial sector, which accounted for 65 percent of total electricity consumption in 2022, offers significant potential for demand-side flexibility (DSF). Developing this flexibility across seven major industries could reduce annual peak load by 3-10 percent and avoid 40–130 GW of new coal power investment.

The document analyzes hydrogen production methods, contrasting the high carbon intensity of fossil fuel-based routes—even those using carbon capture (CCUS)—with the lower impact of water-based electrolysis. It highlights a significant gap between current electrolyser manufacturing capacity and the targets required for the IEA's Net Zero Emissions by 2050 scenario. Reclaim Finance argues that financial support should be restricted to electrolytic hydrogen and prioritized for hard-to-abate sectors like ironmaking and shipping, rather than power storage or heating.

The briefing highlights the lack of a widely agreed-upon definition for 'unabated fossil fuels' despite the term's centrality in G7, G20, and UN climate negotiations. It warns that ambiguous definitions may allow for low carbon capture rates and the exclusion of upstream emissions, potentially stalling climate progress. The author proposes a science-based definition requiring near-total carbon capture (90-95%), permanent geological storage, near-total elimination of upstream and transport emissions, and rigorous third-party verification.
