The study finds a strong linkage between renewable energy generation and sustainable development performance, underscoring the critical role of renewable energy in driving overall sustainability. The complex, nonlinear relationships revealed through impulse response function (IRF) analysis highlight the inherent trade-offs and feedback loops between economic growth, energy use, and sustainability objectives. The key policy implications address both the supply and demand sides of the energy system in Ethiopia. On the supply side, the study emphasizes the need to further expand renewable energy generation to better align with sustainable development goals.

Strong policies are needed to promote its large-scale development.

Therefore, this paper aims to explore the impact of policy on the diffusion of CCS in the cement industry by delving into the interaction mechanisms among agents, including the government, cement companies with and without CCS, CCS technology, and downstream sectors of the cement industry. An agent-based model is developed to simulate the effects of various policy measures on multi-agents’ behaviors and to examine CO<sub>2</sub> emissions, costs, and CCS penetration rates. The results indicate that CCS diffusion will start in 2026, and a diffusion rate of 45.2% will be achieved by 2060, considering China's 30% investment subsidy ratio. The policy with the highest rate of CCS diffusion (62%) and the highest rate of emission reduction (87%) by 2060 provides for a 30% investment subsidy combined with a full quota charge. The 10% investment subsidy policy has the lowest unit cost of abatement (133 CNY/tCO<sub>2</sub>).</div></div>","PeriodicalId":11672,"journal":{"name":"Energy Policy","volume":"199 ","pages":"Article 114527"},"PeriodicalIF":9.3,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143378121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, we test constraints from the EU Taxonomy on CO<sub>2</sub> emissions and on new investments in fossil fuel-based technologies on a case study (district heating: DH). We find that the EU Taxonomy is complex, open to interpretation and that the policy maker needs to build capacity in the economic activity of DH. We also identify that future EU Taxonomy changes to DH activities need to be well thought through and tested as they can have negative impact on investment appetite in DH as well as lead to investments with minor sustainability additions. We also find that in terms of policy focus, the EU Taxonomy is policy output oriented rather than targeting to reshape financial structures to support energy transition, which is troublesome to foster DH investments. A major conclusion is that the EU Taxonomy can have the intended effect in some DH markets, but it can also be redundant in others.</div></div>","PeriodicalId":11672,"journal":{"name":"Energy Policy","volume":"198 ","pages":"Article 114519"},"PeriodicalIF":9.3,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143376563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show the importance of experience and knowledge spillover effects and stable public RD&D expenditures in technology cost developments. To quantify the historical and future cost savings of global solar PV and onshore wind markets, the national market scenario is defined as three countries implement nationalistic policies to reduce their dependence on global markets. By comparing estimated capital costs in global and national market scenarios, this study finds that experience and knowledge spillover effects from global markets save significant costs for three countries. Compared to China, the United States and Germany benefit relatively more from global markets due to higher unit cost savings.

Renewable-fuel regulation standards have been formalizing to ensure that on-grid electrolytic production is primarily powered by renewable electricity. This work evaluates the mid- and long-term impact of integrating renewable hydrogen supply chains into the expansion and operation of the power system using a tailored modification of the open-source energy modeling system (OSeMOSYS). The model optimizes the joint expansion of the Chilean power system and a hydrogen supply chain for exports, between 2025 and 2060, under the European standard for renewable hydrogen. Results show that incorporating renewable hydrogen supply chains that comply with this standard impacts the infrastructure and operation of the power system during its transition towards decarbonization. Between 2025 and 2040, the off-grid hydrogen production scenario results in distributed production, requiring internal hydrogen transport and low grid reliance. Conversely, a scenario that assumes Power Purchase Agreements for renewable electricity results in centralized hydrogen production, with higher electricity transmission investments and grid reliance. For the scenarios studied, the average systemic cost of hydrogen production ranges from $2.9/kgH<sub>2</sub> to $6.4/kgH<sub>2</sub>.</div></div>","PeriodicalId":11672,"journal":{"name":"Energy Policy","volume":"198 ","pages":"Article 114504"},"PeriodicalIF":9.3,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143288086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a concern some production could be constrained as by-products of other metals. This paper provides a conceptional model about the behavior of by-product metals. From this model, scenarios are developed about the types of price-production interaction patterns between by-product and main product metals that might be observed given different situations of by-product metal availability. The paper's aim is to determine if there is evidence of by-product metal production being constrained by the output of the main product metal as the transition to renewable energy continues to grow. For the rare earth metals, the four metals used for renewable energy are shown to move together significantly in price (0.672–0.956) and not to move significantly with the other rare earths prices (0.028–0.351). These results suggest the possibility of a mismatch between overall joint rare earth production and the availability of the separated individual metals. For the base metals, significant statistical correlations (0.787–0.962) between by-product metal and main product metal production with weaker significance for prices (0.093–0.750) was found. These results indicate a possible pattern of production constraint for critical by-product metals as their demand grows. Policy recommendations in the case of constrained by-product metal production are to enhance recycling programs to increase the metals' supply, find new sources for the metals, and develop technology that reduces the metals' need.</div></div>","PeriodicalId":11672,"journal":{"name":"Energy Policy","volume":"198 ","pages":"Article 114515"},"PeriodicalIF":9.3,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143099215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
