Japan is also preparing to import hydrogen through grant-based schemes initiated in October 2024. This study maps and compares stakeholders in both countries using official documents, then conducts semi-structured interviews (11 of 12 targeted decision-makers across companies, research organizations, universities, and a conglomerate) to examine three themes: collaboration with Japan, export feasibility, and diffusion of hydrogen technologies in India. Stakeholders held moderate expectations for Japanese technology licensing (lower than for the United States) and highlighted slow decision-making by Japanese firms; they emphasized local manufacturing in India and the need for Japanese capital to leverage India's strong human talent amid infrastructure and funding constraints. Intellectual property protection was viewed as adequate, suggesting cooperation within the current framework. Medium- to long-term exports to Japan were considered feasible, underpinned by renewable deployment outpacing domestic demand and stable policy support; ammonia was favored as the carrier, whereas liquid hydrogen drew cost and handling concerns. Diffusion in India is expected to take at least a decade, with early uptake in refining, fertilizer, syngas, and iron, and government agencies pivotal via incentives, diffusion support, and public awareness. Key challenges—ecosystem development, cost competitiveness, safety, and demand creation—point to priorities in human capital, regulation, and finance, where Japanese experience could catalyze collaboration.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"90 ","pages":"Article 101884"},"PeriodicalIF":4.9,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145624495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To allow for the reaping of documented benefits bestowed by access to electricity, and to retain the prospect of reaching Sustainable Development Goal 7 by 2030 (access to affordable, reliable, sustainable, and modern energy for all), affordably implementable alternatives to national grid extensions require exploring.

This study combines household survey data with administrative utility billing records for households in Rwanda to examine the extent and nature of misreporting in self-reported electricity spending, using a sample size of 650 households. We find systematic over-reporting among poorer households, primarily due to mismatches between survey recall periods and the irregular, prepaid nature of electricity purchases. To correct for this bias, we adjust reported expenditures using empirical distributions of monthly purchase frequency derived from utility data. Additionally, for unmatched households, we develop predictive models based on household characteristics, though these perform less reliably in data-sparse settings. Extending the analysis to Uganda, we apply both the frequency-based correction and predictive models. Across countries, adjusted estimates suggest electricity burdens for most households lie between 0.5% and 2.5% of total household expenditure across all wealth groups. These findings underscore the limitations of relying solely on household surveys to measure electricity spending in prepaid systems.

The model enables rapid preliminary assessments of both technical and economic performance, requiring minimal input data. Additionally, it incorporates a Life Cycle Assessment to evaluate environmental impacts, an aspect rarely explored in African geothermal studies. The research analyses various technological configurations, including Single Flash, Double Flash, and Organic Rankine Cycle (ORC) systems, aiming to improve efficiency without additional drilling. Findings show that integrating an ORC with existing flash systems can boost energy output by up to 20.1 %, with only a modest rise in the Levelized Cost of Electricity. Compared to the current Olkaria IV setup, hybrid systems demonstrated lower carbon emissions and reduced material resource use per energy output. Results confirm that ORC integration offers the most sustainable pathway for developing high-temperature geothermal resources in the East African Rift. This approach balances energy efficiency, economic feasibility, and environmental impact, providing valuable guidance for future power plant development in regulatory-constrained settings.

This study addresses these challenges and provides insights into the technological, financial and other related aspects for its at-scale adoption. To address the technological aspect of FPV adoption, this study develops a novel selection framework based on specific necessary and conducive conditions to select reservoirs suitable for FPV deployment in India. Applying this framework to a comprehensive dataset of 130 reservoirs in India, 17 reservoirs were identified. We also developed a reservoir ranking framework, to evaluate and rank the 17 identified reservoirs. The analysis revealed that while <em>Almatti</em> reservoir is the most suitable reservoir, <em>Maharashtra</em> emerged as the state with the maximum number of reservoirs, followed by <em>Odisha</em>. To address the financial aspect of FPV adoption, we carried out a levelized cost based economic assessment and found that LCOE for FPV systems ranges from INR 3.16–3.80/kWh which is much lower than the national average. Among the 17 reservoirs, FPV at the <em>Tungabhadra</em> reservoir has the least LCOE of INR 3.16/kWh. For reducing LCOE of FPV vis-à-vis ground-based PV systems, we suggest policies such as interest rate subsidy, capital expenditure subsidy and Generation Based Incentives.
