Researchers from King Abdullah University of Science and Technology have proposed an innovative approach to hydrogen storage by utilizing high-density polyethylene (HDPE) pipelines filled with materials like gravel or sand in lakes and reservoirs. This method is seen as a cost-effective alternative for long-term storage, especially in areas where salt caverns are not available. The technology is considered simple, cheap, and viable in countries like Europe, the United States, Japan, and China within the next decade. The project involves ensuring the pipelines are situated in deep hydropower reservoirs or lakes with flat bottoms to prevent sediment damage. While some environmental impact is anticipated due to the presence of large pipelines, researchers believe the risk to aquatic life and surface explosions is minimal. In parallel, green hydrogen projects are gaining momentum globally. Iberdrola and BP have partnered for a 25 MW green hydrogen initiative in Spain, supported by government funding and expected to commence operations by late 2026. Envision is set to establish Europe's first green hydrogen net-zero industrial park in Spain, contributing significantly to the country's goal of achieving 11 GW of electrolysis capacity by 2030 and creating green job opportunities. Additionally, Industrie De Nora and Asahi Kasei are collaborating to develop containerized, modular electrolyzers for small-scale green hydrogen production. Deutsche ReGas is progressing on the H2 Hub Lubmin project in Germany, aiming to construct a 200 MW electrolysis plant by 2026, with plans for further expansion by 2028. These endeavors underscore a positive trend towards sustainable energy solutions and signify substantial growth in the green hydrogen sector, backed by strategic partnerships, investments, and technological advancements.
