The choice depends on the quantity required. Surface <strong>tanks<\/strong> can store<strong> hundreds of kilograms<\/strong> of hydrogen under pressure, while <strong>underground gas storage<\/strong> can store<strong> thousands of tonnes<\/strong> of hydrogen. By 2050, 270 Twh of H2 storage shall be required, necessitating large and numerous underground storage facilities.<\/p>\n<blockquote class=\"wp-block-quote\">\n<p style=\"text-align: left;\">There are several possibilities to store pure hydrogen. The choice depends on the quantity required<\/p>\n<\/blockquote>\n<p>Regarding <strong>porous reservoirs<\/strong> such as aquifers or depleted fields, the possibilities for storing hydrogen <strong>are still at the R&amp;D level<\/strong>. Indeed hydrogen may chemically or bacterially react with the reservoir materials, potentially leading to the formation of\u00a0 H<sub>2<\/sub>S or in situ methanisation instead of retaining hydrogen as a molecule. Feasibility must be assessed on a case-by-case basis, likely requiring pilot tests for each targeted porous reservoir.<\/p>\n<p>Regarding <strong>salt caverns<\/strong>, there are currently four underground salt cavern storages in the world that store large quantities of hydrogen. Thus, <strong>storing hydrogen<\/strong> in a salt cavern is then <strong>already feasible.<\/strong><\/p>\n<p>Last <strong>underground hydrogen storages<\/strong> are often compared with batteries. Today the biggest battery plant in the world stores the equivalent of 40 tonnes of hydrogen, which is tiny compared to the capacity of a underground hydrogen storage.<\/p>\n<ul>\n<li><strong>What challenges does the storage of hydrogen in salt caverns pose?<\/strong><\/li>\n<\/ul>\n<p>Today the challenges are both financial and technical. <strong>Financially<\/strong>, the circumstances prevent storage operators from making investment decisions, as <strong>the viability<\/strong> of <strong>hydrogen storage<\/strong> business cases and <strong>regulations<\/strong> remain <strong>uncertain<\/strong>. <strong>Technically<\/strong>, operators must still demonstrate that <strong>underground hydrogen storage<\/strong> is safe and beneficial to the future energy system.<\/p>\n<p><strong>The value of underground gas storage<\/strong> today <strong>is linked<\/strong> to <a href=\"https:\/\/goodnewenergy.enagas.es\/en\/innovative\/how-the-spanish-gas-system-works\/\" target=\"_blank\" rel=\"noopener\">supply<\/a> <strong>security<\/strong>, the <strong>system value<\/strong> (infrastructure sizing optimization), and the <strong>arbitrage value<\/strong> (trading).<\/p>\n<p>However, <strong>underground hydrogen storage<\/strong> will also carry an <a href=\"https:\/\/goodnewenergy.enagas.es\/en\/sustainable\/energy-transition-biodiversity-natural-balance\/\" target=\"_blank\" rel=\"noopener\"><strong>environmental<\/strong> value<\/a> (using base load hydrogen instead of fossil fuels) and a <strong>kick-start value<\/strong> (enabling the deployment of RES and balancing their intermittencies).<\/p>\n<blockquote class=\"wp-block-quote\">\n<p style=\"text-align: left;\">There are currently four underground salt cavern storages in the world that store large quantities of hydrogen<\/p>\n<\/blockquote>\n<p>Arbitrage, environmental and kick-start values require high asset flexibility. Demonstrating this high flexibility remains to be proven.<\/p>\n<ul>\n<li><strong>What projects at the European level are being undertaken to analyze the behavior of salt caverns with this mode of operation? And of Storengy in particular?<\/strong><\/li>\n<\/ul>\n<p>Several companies are running pilot projects, either in salt caverns and some in porous reservoirs. Storengy has decided to launch two pilot projects.<\/p>\n<p>The first, called <strong>HyPSTER<\/strong>, aims to demonstrate the <strong>integrity of wells and equipment<\/strong> facing high-frequency cycling of hydrogen. It will also provide some key <strong>insights<\/strong> into the <strong>hydrogen composition<\/strong> withdrawn from a cavern.<\/p>\n<p>The second, called <strong>FrHyGe<\/strong>, in which Enag\u00e1s is also participating, will involve real cycling of several tonnes of hydrogen at moderate flow. <strong>It shall help to improve the construction and process knowledge with hydrogen<\/strong>. As no pipe is connected yet, the tests will be somewhat limited.<\/p>\n<blockquote class=\"wp-block-quote\">\n<p style=\"text-align: left;\">FrHyGe, a project in which Enag\u00e1s is also participating, will involve real cycling of several tonnes of hydrogen at moderate flow<\/p>\n<\/blockquote>\n<p>Today, <strong>Storengy<\/strong> is pushing for industrial-level projects in the UK and Germany where regulation and government support seem more appropriate for such CAPEX-intensive projects.<\/p>\n<ul>\n<li><strong>Is Europe well positioned in this area to respond to future hydrogen demand?<\/strong><\/li>\n<\/ul>\n<p>For 2030, we need 45 TWh of storage capacity in Europe by 2030 to comply with REPower EU ambition.
