Underground Hydrogen Storage: Transforming Subsurface Science into Sustainable Energy Solutions

Energies, Journal Year: 2025, Volume and Issue: 18(3), P. 748 - 748

Published: Feb. 6, 2025

As the global economy moves toward net-zero carbon emissions, large-scale energy storage becomes essential to tackle seasonal nature of renewable sources. Underground hydrogen (UHS) offers a feasible solution by allowing surplus be transformed into and stored in deep geological formations such as aquifers, salt caverns, or depleted reservoirs, making it available for use on demand. This study thoroughly evaluates UHS concepts, procedures, challenges. paper analyzes most recent breakthroughs technology identifies special conditions needed its successful application, including site selection guidelines, technical factors, significance characteristics. The integrity wells caprock, which is important safe efficient storage, can affected operating dynamics cycle, notably fluctuations pressure stress within formations. To evaluate potential broader adoption, we also examined economic elements cost-effectiveness practicality storage. We reviewed current efforts identified key knowledge gaps, primarily areas hydrogen–rock interactions, geochemistry, gas migration control, microbial activities, geomechanical stability. Resolving these technological challenges, regulatory frameworks, environmental sustainability are UHS’s long-term extensive integration industry. article provides roadmap research development, emphasizing need further fully realize technology’s promise pillar economy.

O&G, Geothermal Systems, and Natural Hydrogen Well Drilling: Market Analysis and Review

Energies, Journal Year: 2025, Volume and Issue: 18(7), P. 1608 - 1608

Published: March 24, 2025

Developing clean and renewable energy instead of the ones related to hydrocarbon resources has been known as one different ways guarantee reduced greenhouse gas emissions. Geothermal systems native hydrogen exploration could represent an opportunity diversify global matrix lower carbon-related All these natural sources require a well be drilled for its access and/or extractions, similar petroleum industry. The main focuses this technical–scientific contribution research are (i) evaluate matrix; (ii) show context over years future perspectives on geothermal exploration; (iii) present analyze importance developing technologies drilling process optimization aiming at accessing resources. In 2022, was composed mainly nonrenewable such oil, gas, coal, where combustion fossil fuels produced approximately 37.15 billion tons CO2 in same year. 2023, USD 1740 invested globally reduce emissions combat context, currently, about 353 power units operation worldwide with capacity 16,335 MW. addition, globally, there 35 under pre-construction (project phase), 93 already being constructed, recently, 45 announced. Concerning hydrogen, industry announced 680 large-scale project proposals, valued 240 direct investment by 2030. Brazil, company Petroleo Brasileiro SA (Petrobras, Rio de Janeiro, Brazil) will invest coming nearly 4 million involving generation, since (oil systems, among others) achieved through wells, document presents contextualization social interest.
