The report identifies significant energy gaps in Nigeria's healthcare system, noting that 40% of primary healthcare centres (PHCs) lack electricity. It proposes a phased roadmap to electrify 10,000 functional PHCs by 2030, estimating a total cost of $525 million for CAPEX and OPEX over 15 years. The document analyzes three delivery models—traditional equipment ownership, service-based, and a proposed hybrid model—recommending the hybrid approach for Type 2 PHCs to balance private sector efficiency with public sector constraints. Key recommendations include the creation of a centralized dynamic database for health facility energy status and the use of blended financing to mitigate risks for private energy service companies.

The report identifies a significant energy access gap in Sierra Leone's schools, with 86% of primary schools lacking electricity. It proposes a three-phase roadmap (2023–2029) to electrify over 9,500 schools using solar PV systems, estimating a total investment need of $90 million for secondary schools alone. The analysis emphasizes the need for a shift from donor-led equipment ownership to sustainable service-based or hybrid delivery models to ensure long-term operation and maintenance (O&M).

The document analyzes the climate impact of methane from U.S. dairy and swine manure, arguing that while biogas digesters are the primary focus of funding, they are often impractical for small and medium farms. It proposes underutilized alternatives—specifically solid-liquid separation, acidification, and aeration—which can reduce emissions more cost-effectively and provide on-farm benefits like odor control and improved fertilizer value. The author calls for expanded pilot programs, better data collection, and targeted financial support to scale these alternatives.

The document evaluates over 20 combinations of power-generating technologies and cooling systems to identify strategies for reducing the environmental footprint of China's power sector. It highlights energy efficiency as the most cost-effective and impactful strategy for reducing both emissions and water use. While wind and run-of-river hydroelectric power are identified as low-impact alternatives, the report warns that certain low-carbon technologies, such as Concentrated Solar Power (CSP) and Carbon Capture and Storage (CCS), can significantly increase water consumption. The World Resources Institute recommends that China implement sectoral water withdrawal quotas and align technology deployment with regional water availability.

The report argues that Concentrating Solar Thermal power (CST) is a viable large-scale, zero-carbon alternative to coal-fired power, particularly when combined with thermal storage to meet baseload demand. While currently more expensive than coal, costs are expected to decline through technology learning, R&D in materials and optical design, and economies of scale from larger plants. The document highlights that a carbon price of approximately $115 per ton of CO2 would make CST with 6 hours of storage economically competitive with coal. It emphasizes the need for stable policy support, such as feed-in tariffs, to bridge the current cost gap and calls for increased deployment in rapidly developing economies like China and India to alter their emissions trajectories. Additionally, the report notes that widespread CST adoption requires improved transmission infrastructure, specifically federal coordination in the U.S. and links between the EU and North Africa.

The document examines next-generation geothermal technologies—including enhanced geothermal systems, closed-loop, and superhot systems—which differ from conventional methods by drilling into hot rocks lacking natural fluid or permeability. While these technologies offer potential for 24/7 clean electricity globally and in the United States, their commercialization requires cost reductions, the mitigation of environmental risks, and the resolution of financing and permitting barriers.

The paper evaluates various renewable and clean energy technologies for Tamil Nadu, analyzing their Technology Readiness Levels (TRLs), current installation capacities, and barriers to adoption. It identifies significant potential for wind repowering, offshore wind development, solar PV expansion, and the deployment of battery energy storage systems (BESS). Additionally, it examines the role of green hydrogen and bioenergy in the state's energy mix, emphasizing the need for supportive policies and infrastructure to facilitate the transition.

The document highlights the global investment in battery research and development to lower costs and improve performance, specifically focusing on the current state of EV battery technologies and research in India.

The document examines carbon mineralization and enhanced root crops as potential carbon removal strategies. Carbon mineralization, which uses reactive materials to form solid carbonate minerals, could remove 410 MtCO2 per year if one-third of the construction aggregate market shifted to mineralized aggregate. Enhanced root crops, though theoretical, could sequester up to 185 MtCO2 per year across 249 million acres of major U.S. crops. Both technologies face significant research and development hurdles and require sustained federal funding to resolve unknowns regarding scalability, environmental impacts, and commercial viability.
