Current stringent policies in the EU and US are set to soon require hourly time matching of renewable electricity generation used by electrolyzers, aimed at ensuring that hydrogen production does not cause significant direct or indirect emissions. While such requirements enhance the “green credentials” of hydrogen, they also increase its production costs. A modest relaxation of these requirements offers a practicable route for scaling up low-carbon hydrogen production, optimizing both costs and emission reductions. Moreover, in jurisdictions with credible and near-to-medium-term decarbonization targets, immediate production of electrolytic hydrogen utilizing grid electricity would have a lifetime carbon intensity comparable to or even below blue hydrogen and very significantly less than that of diesel, emphasizing the need to prioritize rapid grid decarbonization of the broader grid.</div></div>","PeriodicalId":342,"journal":{"name":"iScience","volume":"28 3","pages":"Article 111955"},"PeriodicalIF":4.6,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143509065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prior work in the nematode <em>Caenorhabditis elegans</em> demonstrated that loss of PNP ortholog PNP-1 induced an immune response called the intracellular pathogen response (IPR). Here, we show that loss of the enzyme upstream of PNP-1 called ADAH-1 (ADA homolog) also induces the IPR and promotes resistance against intracellular pathogens.

Importantly, we find that supplementation of deoxyadenosine, a substrate for ADA, induces the IPR and promotes resistance to intracellular pathogens in <em>C. elegans</em>, a finding we extend to human cells.
