However, determining which industries to target, the scale of the opportunity, and how to meet the hydrogen demand out to 2050 is complex and highly uncertain. The most significant decarbonization opportunity identified in this review is in the refining and chemicals industries, where annual emissions could reduce by up to 24% by 2050 from 2021 levels if emissions-intensive grey hydrogen is replaced with clean hydrogen. New (clean) hydrogen applications include replacements for carbon-based reductants in steelmaking (≤18% steelmaking emissions reduction by 2050) and fuel for high-temperature heat in cement, aluminum, and glassmaking, with annual sectoral emissions reductions by 2050 of up to 23%, 3%, and 32% respectively. Hydrogen technologies have high readiness levels and face modest technical barriers in burner and furnace design.

Accordingly, this research first studies how the trade-offs between energy trilemma dimensions are formed through different regimes in the twenty-five large energy consumers during 2004–2021. Then, the time-varying transition of the switching states in response to the hydrogen economy and geopolitical risks is investigated. To that end, a Markov-switching panel vector autoregressive method with time-varying transition is applied. Finally, this research assesses the performance of energy trilemma in response to a change in the pivotal policy instruments, using the generalized method of moments estimator. The regime-switching impulse-response analysis supports the short-term trade-offs between the dimensions under two regimes. Further, the development of the hydrogen economy increases the p-value of remaining in regime 1 as the dominant regime with the trade-offs; “upward”, “downward”, and “upward” states for the dimensions respectively, while the escalation of geopolitical risks declines the transition probability from regime 2 into regime 1. Finally, the existence of a causal and long-term relationship between energy trilemma and the policy instruments is assessed through the generalized method of moments. The policymakers should present the role of green transition, complexity, and geostrategy policies on nonlinear trade-offs between the dimensions is crucial for ensuring energy equity, maintaining energy security, and accelerating environmental sustainability and hence, a regime-switching balanced growth of energy trilemma.

The research provides a comprehensive review of the current research status of the suction valve stepless capacity regulation technology, covering its main forms, system characteristics, structural advantages, and performance benefits. Based on this, the research also analyzes the existing issues related to this technology, introduces emerging technologies in the field of capacity regulation, and discusses future development directions. The aim is to provide a reference for energy-saving, efficiency improvement, and low-carbon development of compressors. The analysis shows that the intake valve stepless capacity regulation technology is primarily implemented through a partial stroke, top-opening regulation system. The essence of this system is hydraulic drive control, which has defects such as small flow areas, large resistance losses, severe impact, complex actuator systems, and multiple failure points.

In 2021, it implemented the policy of emission trading scheme to manage emissions from electricity sector. However, such a policy is unable to achieve its emission-mitigation target. This study aims to analyze the socio-economic effects of early carbon peak (i.e., before 2030) and sectoral coverage in emission trading scheme, as well as reveal the composite effects of multiple impact factors regarding the scheme and their interactions, through the development of a factorial emission-trading equilibrium model. It is found that the implementation of such policies would result in reductions in commodity output by sectors and further lead to the loss of real GDP. Specifically, the earlier the emission peak, the higher the GDP loss and carbon price. Meanwhile, the increase in the commodity price induced by the advance of the emission-peak point would result in a growth in commodity imports. Additionally, there are complex non-functional relationships that exist between industry coverage in emission trading scheme and the related multi-dimensional impact factors. The interactive relationships between emission-peak point and industry coverage in emission trading scheme would result in significant compound effects on the real GDP and carbon price, which are recommended to be considered while formulating relevant policies. Advance plans with corresponding allowances/benefits are also recommended to offset the impacts on households induced by implementing emission trading scheme-related policies.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"214 ","pages":"Article 115476"},"PeriodicalIF":16.3,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143454100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Regulatory uncertainty is a critical barrier to infrastructure development, undermining business models and deterring investments. Key issues include defining energy tariffs, taxation policies, and classifying energy as a commodity or service. The study underscores the urgency of regulatory advancements and highlights risks associated with the absence of an adaptive framework for fostering national electric mobility. The primary objective is to demonstrate how a “core” regulatory experimentation process can lay the foundation for “satellite” initiatives aimed at constructing a flexible regulatory framework tailored to emerging technologies. It also addresses the critical role of energy distributors and the necessity of designing a novel tariff model for charging infrastructure, enabling pre-legislative testing of regulatory measures. Also, by aligning with the existing tariff sandbox overseen by the Brazilian National Electric Energy Agency, operational in the country, and drawing on Italy's successful experience, this research explores the sandbox's potential to establish adaptive regulatory signals conducive to technological evolution in electric mobility, aligned with Sustainable Development Goals (SDG 7 and 13).</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"213 ","pages":"Article 115496"},"PeriodicalIF":16.3,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143438126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
