The US Inflation Reduction Act incentivizes low-carbon hydrogen production through tax credits that vary based on life-cycle greenhouse gas emissions intensity of hydrogen. Blue hydrogen or hydrogen produced from natural gas coupled with carbon capture and sequestration is one such pathway. Here we develop a geospatial, measurement-informed model to estimate supply-chain specific life-cycle greenhouse gas emissions intensity of blue hydrogen produced with natural gas sourced from the Marcellus and Permian shale basins. We find that blue hydrogen production using Permian gas has a life-cycle emissions intensity of 7.4 kg carbon dioxide equivalent per kg hydrogen (kgCO2e kg−1 H2), more than twice that of hydrogen produced using Marcellus gas of 3.3 kgCO2e kg−1 H2. Eligibility for tax credits should therefore be based on life-cycle assessments that are supply-chain specific and measurement informed to ensure blue hydrogen projects are truly low carbon. New work highlights the importance of basing US Inflation Reduction Act tax credits for low-carbon hydrogen production on life-cycle greenhouse gas emissions intensity assessments that are project- and supply-chain specific and informed by direct measurements of methane emissions.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"9 12","pages":"1571-1582"},"PeriodicalIF":49.7,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41560-024-01653-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142430557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is primarily due to the prevalence of side reactions, particularly at low potentials on the negative electrode, especially in state-of-the-art Li-ion batteries where the charge cutoff voltage is limited. However, as the quest for high-energy battery technologies intensifies, there is a pressing need to advance the study of cathode–electrolyte interphase properties. Here, we present a comprehensive approach to analyse the cathode–electrolyte interphase in battery systems. We underscore the importance of employing model cathode materials and coin cell protocols to establish baseline performance. Additionally, we delve into the factors behind the inconsistent and occasionally controversial findings related to the cathode–electrolyte interphase. We also address the challenges and opportunities in characterizing and simulating the cathode–electrolyte interphase, offering potential solutions to enhance its relevance to real-world applications. The cathode–electrolyte interphase (CEI) is vital for battery cell capacity and stability but receives less attention than the solid–electrolyte interphase. The authors review CEI properties, emphasize using model cathode materials and coin cell protocols, and address challenges and opportunities in characterizing and simulating CEI for real-world applications.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"9 12","pages":"1463-1473"},"PeriodicalIF":49.7,"publicationDate":"2024-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142383663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We find that the total value of available credits exceeds estimated battery production costs, but qualifying for all available credits is difficult. IRA cell and module credits alone bring estimated US battery production costs in line with China. In contrast, IRA material extraction and processing credits are modest. IRA’s end-user purchase credits are restricted to electric vehicles whose battery supply chains exclude foreign entities of concern, including China. This incentivizes diversification of the entire supply chain, but leasing avoids these restrictions. Lithium iron phosphate batteries have potential to more easily reduce supply chain vulnerabilities and qualify for incentives, but they have smaller total available incentives than nickel/cobalt-based batteries. Overall, the IRA primarily incentivizes downstream battery manufacturing diversification, whereas upstream supply implications depend on automaker responses to foreign entities of concern and leasing rules. The Inflation Reduction Act increases the competitiveness of US electric vehicle battery manufacturing and incentivizes supply chain diversification, but reducing vulnerabilities will depend on automaker choices in battery design and navigating regulations.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"9 12","pages":"1561-1570"},"PeriodicalIF":49.7,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142362748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We evaluate characteristics of electricity variability due to weather variations by calculating 1,600 years of daily production and demand. Focusing on five European countries—chosen for their energy mix including hydropower—we find that energy droughts result from processes that cause (temporally) compounding impacts in the energy and meteorological system. These can turn what might have been short-term droughts into prolonged high unmet energy demand. For instance, low reservoir inflows in spring quadruple the chance of prolonged energy droughts: reduced snowpack and rainfall lower hydro availability but also dry out subsoils, increasing the chance of heatwaves and therewith extending the energy problems into summer. We identify and quantify three compounding energy/climate conditions and the associated characteristics and risks of multi-year energy droughts, crucial for informing future energy system design. As Europe’s renewable energy grows, energy droughts become more likely. This analysis of daily production and demand from five EU countries shows that compounded weather impacts, such as low spring reservoir inflows, can quadruple drought risks in summer and winter.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"9 12","pages":"1474-1484"},"PeriodicalIF":49.7,"publicationDate":"2024-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142324981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
