Global Scans · Hydrogen · Weekly Summary

• [New] Low-emissions hydrogen production includes historical values for 2020 and 2024 and an estimate of the potential production in 2030 from projects that have at least reached final investment decision (FID) and target operation before 2030. IEA
• [New] We find that the net forcing change in 2050 from all emissions associated with hydrogen deployment is strongly negative, with the cooling contribution from decreasing CO2 emissions larger than all other effects. AGU Journals
• [New] Because NOx emissions changes are growing over time from 2020 to 2050 as hydrogen deployment increases and because we report the average annual forcing changes in 2050, the nearer-term ozone effect dominates the longer-term methane effect. AGU Journals
• [New] Examining non-CO2 emissions more closely, we find that hydrogen emissions increase across all scenarios (+2.1 to 6.2 Mt in 2050), with larger increases in the High cases compared to the Low cases as expected. AGU Journals
• [New] The displacement of unabated fossil energy due to the imposed hydrogen deployment leads to reductions in global CO2 emissions in 2050 (relative to the No H2 case) that range between roughly 1,200 and 1,600 Mt CO2 per year. AGU Journals
• [New] While pipelines supply about a third of the hydrogen consumed in 2050, the Green H2 cases have slightly more delivered by pipeline, and therefore less delivered by truck than the Blue H2 cases. AGU Journals
• [New] Liquid fuels represent more than half of the total final energy displaced by hydrogen by 2050. AGU Journals
• [New] As early as 2035, hydrogen combustion emission factors drop to 125% of the equivalent gas-fired technology once their GDP per capita for a given model period reaches or exceeds that of China in 2010. AGU Journals
• [New] Hydrogen production is assumed to follow production in the Pipeline H2 T & D, High Demand case after subtracting hydrogen utilized for natural gas/hydrogen blends, resulting in roughly 19 EJ of total low-carbon hydrogen production in 2050. AGU Journals
• [New] Median global hydrogen deployment in IPCC 1.5 °C scenarios is about 13 EJ in 2050, with some scenarios projecting substantially more (Byers et al., 2022). AGU Journals
• [New] Across all scenarios considered, when compared to a scenario without expanded hydrogen deployment, reduced forcing from lower CO2 emissions is larger than other forcing changes by 2050 even after accounting for hydrogen and other indirect forcers. AGU Journals
• [New] The European Union, under its REPowerEU plan, aims to produce 10 Mt of renewable hydrogen domestically by 2030 and import another 10 Mt, as stated by the European Commission. Precedence Research
• [New] If all announced projects are realized, low-emission hydrogen capacity could reach nearly 49 Mt per annum by 2030. Precedence Research
• [New] Through Vision 2030 and its Hydrogen Strategy, Saudi Arabia aims to capture over 10% of the global hydrogen trade by the mid-2030s. Precedence Research
• [New] By 2030, Germany aims to achieve 10 GW of electrolyzer capacity, marking a significant step toward decarbonizing its hydrogen sector. Precedence Research
• [New] Large-scale electrolysis-based renewable hydrogen is set to become the dominant sub-segment by the 2030s, as green supply certification, cross-border import routes, and auction systems continue to evolve. Precedence Research
• [New] Under MIT's Net Zero by 2050 scenario, achieving net zero would cost approximately 30% more without hydrogen. / USA MarketScreener
• [New] Realizing planned hydrogen projects by 2030 would require more than USD 1,500 billion in cumulative investment in new power generation alone. Green Fuel Journal
• [New] The IEA projects the cost gap between green and blue hydrogen to narrow significantly by 2030, with green potentially becoming cost-competitive in high-renewable-resource regions like China and parts of Europe before the end of this decade. Green Fuel Journal
• BloombergNEF projects hydrogen could meet up to 22% of final energy demand by 2050. Canadian Mining & Energy
• Fastest Growing Segment: Marine & Shipping is the fastest growing end-use segment, propelled by the IMO 2023 Strategy mandating 40% carbon intensity reduction by 2030 and net-zero by 2050, creating a structured, deadline-driven procurement pipeline for high-power marine hydrogen combustion engines.
