Over the next few years, it is planned to convert all or part of underground gas storage (UGS) facilities used for natural (salt caverns, depleted hydrocarbon reservoirs, and deep aquifers) into dihydrogen (H2) reservoirs. These environments host microbial communities, some which are hydrogenotrophic (sulfate reducers, acetogens, methanogens). The current state microbiological knowledge thus presented three types UGS facilities. In mid-1990s, concept anaerobic subsurface lithoautotrophic ecosystems, SLiMEs, emerged. It expected that large-scale injection H2 will generate new ecosystems called artificial could persist over time. SLiMEs lead loss, an intense methanogenic activity, a degradation quality risk installations through sulfide production. However, recent studies on salt caverns aquifers suggest activity also leads alkalinization (up pH 10), can constrain hydrogenotrophy. Therefore, studying understanding these both necessity development industry presents opportunity ecologists monitor evolution in real
