MAINTAINING A RELIABLE GRID UNDER EPA’S PROPOSED 111 RULES RESTRICTING POWER PLANT EMISSIONS
The report asserts that the EPA's proposed rules for coal and gas power plants are technically feasible and will not threaten resource adequacy or operational reliability. It synthesizes six industry-standard studies showing that the U.S. grid can remain stable even if all unabated coal is retired by 2035. The authors argue that reliability risks are institutional rather than technical, stemming from slow interconnection processes and inadequate transmission planning. To manage the transition, the report recommends adopting 'connect-and-manage' interconnection processes, deploying grid-enhancing technologies, and proactively planning transmission for coal retirements.

DRAFT CORPORATE CLIMATE STOCKTAKE: CONCRETE AND CEMENT SECTOR
The report identifies clinker production as the primary source of emissions in the cement sector, accounting for 88% of total emissions. It evaluates three main decarbonization levers: substituting clinker with materials like fly ash and calcined clay, replacing coal and gas with biomass, waste, or green hydrogen, and deploying CCUS. While some progress is noted in developed markets, the report warns that absolute emissions will rise as production grows in emerging markets like India and Africa unless green processes are scaled. Key barriers include supply constraints for substitutes, high upfront costs for CCUS, and a lack of carbon transport infrastructure in high-growth regions.

Comments on Changes to Proposed Advanced Clean Truck Regulation
A coalition led by Earthjustice urges the California Air Resources Board to increase zero-emission (ZE) truck sales targets, arguing that initial proposals are insufficient to meet the state's 2045 carbon neutrality goals. Citing analysis from Lawrence Berkeley National Laboratory, the authors claim that without stronger mandates, carbon emissions from trucking would only drop by 18% by 2045. The letter proposes specific higher sales percentages for Class 7-8 tractors to meet drayage fleet goals by 2035 and calls for a 'work backwards' approach from 2040 fleet goals to eliminate internal combustion engine (ICE) vehicle sales for urban delivery by 2033. The coalition asserts that technological advancements, falling battery costs, and corporate commitments from entities like Amazon and UPS make these higher targets feasible, shifting the primary barriers from technical or economic to logistical planning.

CHARTING CALIFORNIA’S CARBON COURSE: WHY AND HOW THE STATE SHOULD SET A 2030 TARGET OF 40% BELOW THE 1990 LEVEL OF CARBON EMISSIONS
The report proposes a 2030 target for California to reduce carbon emissions to 40% below 1990 levels, asserting that this is technically feasible and economically viable. It recommends maintaining a policy portfolio where a broad cap-and-trade program acts as an emissions ceiling over sector-specific policies. To manage costs and uncertainty, the author suggests extending current cost-containment tools, including a three-tiered allowance reserve and a forward-borrowing mechanism. The analysis incorporates both capped emissions and uncapped sectors—such as agriculture and waste—predicting that the state can reach the target through commercially available technology and induced innovation in clean tech industries.

Hydrogen as a Gas Turbine Fuel
The document examines the transition from natural gas to hydrogen in gas turbines, detailing the physical differences between the fuels and the resulting engineering requirements. It highlights that while low-percentage hydrogen blends (~20% or less) can often be used with minimal modifications, higher blends require significant changes to combustion systems to manage NOx emissions and prevent flashback. The paper reviews the current capabilities and development roadmaps of major OEMs, including Ansaldo Energia, General Electric, Mitsubishi Hitachi Power Systems, and Siemens, most of whom target 100% hydrogen capability by 2030.

Assessing Clean Energy Opportunities Through Demand Aggregation in Bengaluru’s Apartment Buildings
The study of ten apartment complexes in Bengaluru found that rooftop solar could meet the entire annual electricity demand for common services in 80% of the sites. Water pumping assets represent the largest electricity load, accounting for 45% of the total connected common area load across the studied complexes. Despite this potential, adoption is hindered by low incentives due to subsidized domestic tariffs in Karnataka, a lack of maintained energy data, and a priority on other budgetary items like waste management over energy efficiency.
