In high-cost, high-density urban contexts, these impacts intersect with financial strain, housing precarity, and constrained daily routines. This study examines how vulnerable households in urban Hong Kong experience, interpret, and manage the well-being impacts of energy insecurity in their everyday lives. Drawing on semi-structured interviews with individuals experiencing energy insecurity and key informants, the study explores energy-related stress and anxiety, implications for quality of life and housing conditions, and the coping practices adopted under persistent affordability pressures. The findings show that high energy costs compel households to prioritise utility payments over other basic needs, generating chronic stress, strained relationships, and restricted daily functioning. Although households employ multiple coping strategies, including behavioural adjustments, outsourcing thermal comfort, reliance on community support, and reductions in comfort expectations, these practices seldom improve well-being. Instead, they reflect processes of constrained adaptation and reluctant endurance under ongoing financial and housing constraints. The study further demonstrates how restricted energy use and associated hardships become normalised over time, shaping everyday routines rather than discrete crisis experiences. Housing conditions play a central mediating role, with substandard and insecure living environments intensifying energy needs and exposure to health and safety risks. While grounded in Hong Kong's dense urban context, the processes identified highlight broader patterns relevant to other high-cost, high-density cities where energy affordability, housing precarity, and well-being are closely intertwined.</div></div>","PeriodicalId":11546,"journal":{"name":"Energy Strategy Reviews","volume":"66 ","pages":"Article 102306"},"PeriodicalIF":12.1,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148540507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results reveal that Chinese OFDI and technological innovation significantly reduce long-run CO₂ emissions, with elasticities of −0.27% and −0.23%, respectively, whereas tourism development has a positive and significant effect on CO2 emissions (elasticity: 0.11%). The results further reveal substantial regional heterogeneity. Chinese OFDI reduces CO₂ emissions in South Asia, East Asia, and the MENA region, while increasing CO₂ emissions in Central Asia, Central &amp; Eastern Europe, Western Europe, and the Commonwealth of Independent States (CIS). Moreover, the interaction between OFDI and tourism development intensifies CO₂ emissions, highlighting a critical policy paradox: infrastructure investment promotes tourism development while simultaneously degrading the environmental resources that are important for long-run tourism competitiveness.

Existing studies frequently assess lithium-ion batteries and hydrogen-based storage technologies independently and often overlook the strategic interactions among governments, energy producers, investors, and technology providers that shape deployment decisions under market uncertainty. This study develops a game-theoretic framework to evaluate the market dynamics, financial risks, and economic viability of hydrogen-based energy storage systems and lithium-ion batteries within China's evolving low-carbon energy landscape. The model captures both competitive and cooperative stakeholder behaviours under varying policy, technology, and market conditions, incorporating capital investment requirements, operational performance, technological maturity, carbon pricing mechanisms, government incentives, and energy price volatility. Results indicate that lithium-ion batteries maintain a near-term economic advantage and dominate short-duration storage applications due to lower capital costs and higher technological maturity. However, hydrogen-based energy storage exhibits superior long-term potential for large-scale and seasonal storage, particularly in regions characterized by abundant renewable energy resources and increasing system flexibility requirements. The analysis further demonstrates that infrastructure investment risk, technology adoption uncertainty, policy fluctuations, and market volatility significantly influence stakeholder decision-making and project profitability. Government subsidies, carbon pricing instruments, and strategic partnerships are found to substantially reduce investment risks and improve the economic feasibility of hydrogen storage deployment. Moreover, cooperative strategies among stakeholders generate greater economic returns and accelerate technology diffusion compared with purely competitive market behaviour. These findings suggest that coordinated policy support and stakeholder collaboration can enhance the commercial viability of hydrogen-based energy storage while complementing lithium-ion battery deployment, providing valuable guidance for policymakers, investors, and energy planners seeking to optimize energy storage investments and support China's long-term transition toward a resilient, low-carbon energy system.</div></div>","PeriodicalId":11546,"journal":{"name":"Energy Strategy Reviews","volume":"66 ","pages":"Article 102304"},"PeriodicalIF":12.1,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148555348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the trade-energy-emissions-health relationship in the region has been studied with a range of parametric and single-country models, comparatively little descriptive work has placed CO₂ intensity and CO₂ damages alongside trade openness, energy consumption, and health expenditure across the full set of South Asian economies. This study addresses that descriptive gap. Using publicly available country-level data for Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka over 1990–2020, we conduct an exploratory, comparative analysis using descriptive statistics, one-sample t-tests with Cohen's d and Hedges' g effect sizes, and the one-sample Chi-square and Kolmogorov–Smirnov non-parametric tests. The analysis is distributional and country-comparative; it does not estimate causal effects or long-run dynamic relationships. The results indicate that India, Sri Lanka, and Maldives correspond to the upper end of the regional distribution for CO₂-related indicators, while Bhutan, Nepal, and Afghanistan are linked with higher relative health expenditure. These cross-country patterns are associated with the qualitative expectations of the Environmental Kuznets Curve and Ecological Modernization Theory, which are used here as interpretive frameworks rather than empirically tested theories. The findings suggest directions for future panel-econometric, SEM, and dynamic modelling research aimed at assessing causal and long-run mechanisms.</div></div>","PeriodicalId":11546,"journal":{"name":"Energy Strategy Reviews","volume":"66 ","pages":"Article 102311"},"PeriodicalIF":12.1,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148555349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over 70 stakeholders across three workshops and seven bilateral meetings co-defined the model structure, assumptions, and scenarios. Stakeholders voted on individual model parameters against a quantitative acceptance threshold before they entered model runs. The resulting CLEW-CR model produced the quantitative content of Costa Rica's 2020 NDC, as explicitly acknowledged in the official NDC document. Over 15 scenarios were produced to inform the country's dialogue. A comparison of business-as-usual and decarbonization scenarios shows that deploying the NDC by 2030 and the National Decarbonization Plan by 2050 would yield a net economic benefit of US$55 billion.

This paper presents a critical review of PV–EV integrated SHEMS from a control-oriented and sustainability-driven perspective. The literature is systematically analyzed across architectural paradigms, uncertainty modeling, energy storage coordination, EV charging strategies, and reinforcement learning (RL) applications. The review identifies a persistent gap between advanced learning algorithms and deployable, grid-interactive residential implementations aligned with decarbonization objectives. To bridge this gap, a reinforcement learning–enabled cyber–physical framework is proposed that integrates data-driven forecasting, structured state–action modeling, degradation-aware reward design, and hierarchical coordination of PV, ESS, and EV resources. The proposed framework emphasizes transparency, computational feasibility, and compatibility with real-time operation. By linking algorithmic intelligence to renewable integration, peak demand mitigation, and emission-reduction goals, this work outlines a scalable pathway toward resilient, sustainability-oriented PV–EV-integrated smart homes.</div></div>","PeriodicalId":11546,"journal":{"name":"Energy Strategy Reviews","volume":"66 ","pages":"Article 102303"},"PeriodicalIF":12.1,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148555384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Local solar radiation, ambient temperature, and wind speed data were used to estimate renewable electricity generation and assess system behavior under hydrogen demand levels of 100-400 kg H2/day. A techno-economic model was developed to calculate capital cost, operating cost, and the levelized cost of hydrogen (LCOH) for PV, WT, and hybrid PV/WT configurations over different project lifetimes. The results show that PV-based systems perform better than wind-based and hybrid alternatives under Guangdong's resource conditions. At a refueling capacity of 400 kg H2/day, the 5 MW PV system supplied 80% of the station electricity demand from renewable energy, compared with 69% for the hybrid system and 17% for the wind-only system. The lowest LCOH was obtained for the 5 MW PV configuration over a 20-year lifetime, reaching 4.5 €/kg H2, while the hybrid and wind-based cases resulted in higher hydrogen costs.
