The maximum formate concentration reached 0.81\u2005mol\/L after 18\u2005h. The resulting formate salt solution (0.81\u2005mol\/L) was subsequently converted into FA (0.50\u2005mol\/L) with a 96\u2009% yield by exchange of the cation (K\u2009+ to H\u2009+) using an ion exchange resin. FA was then dehydrogenated to regenerate hydrogen, achieving a FA conversion exceeding 98\u2009%. This process yielded an overall hydrogen recovery rate of over 90\u2009%. These findings demonstrate a viable method for hydrogen storage and regeneration using formate salts as an efficient hydrogen carrier for future energy applications.\n                  <\/jats:p>","DOI":"10.1002\/open.202500032","type":"journal-article","created":{"date-parts":[[2025,3,11]],"date-time":"2025-03-11T18:54:41Z","timestamp":1741719281000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Hydrogen Storage and Release via Carbon Dioxide Hydrogenation to Formate Salts under High\u2010Pressure Conditions with Ir Complex and Subsequent Formic Acid Dehydrogenation"],"prefix":"10.1002","volume":"14","author":[{"given":"Seo","family":"Ono","sequence":"first","affiliation":[{"name":"Interdisciplinary Research Center for Catalytic Chemistry National Institute of Advanced Industrial Science and Technology  1-1-1 Higashi Tsukuba 305-8565 Ibaraki Japan"},{"name":"Graduate School of Pure and Applied Science University of Tsukuba  1-1-1 Tennoudai Tsukuba 305-8577 Ibaraki Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0790-956X","authenticated-orcid":false,"given":"Ryoichi","family":"Kanega","sequence":"additional","affiliation":[{"name":"Research Institute for Energy Conservation Department National Institute of Advanced Industrial Science and Technology  1-1-1 Higashi Tsukuba 305-8565 Ibaraki Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2679-2662","authenticated-orcid":false,"given":"Hajime","family":"Kawanami","sequence":"additional","affiliation":[{"name":"Interdisciplinary Research Center for Catalytic Chemistry National Institute of Advanced Industrial Science and Technology  1-1-1 Higashi Tsukuba 305-8565 Ibaraki Japan"},{"name":"Graduate School of Pure and Applied Science University of Tsukuba  1-1-1 Tennoudai Tsukuba 305-8577 Ibaraki Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,2,25]]},"reference":[{"key":"e_1_2_6_1_1","doi-asserted-by":"publisher","DOI":"10.1021\/cr4002758"},{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1063\/1.90403"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/0360-3199(86)90154-0"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1039\/b907569k"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1021\/acs.organomet.3c00286"},{"key":"e_1_2_6_4_3","doi-asserted-by":"publisher","DOI":"10.1186\/s40807-024-00102-6"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.201507458"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/anie.199522071"},{"key":"e_1_2_6_5_3","doi-asserted-by":"publisher","DOI":"10.1021\/acs.chemrev.5b00197"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1021\/ja903574e"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja2035514"},{"key":"e_1_2_6_6_3","doi-asserted-by":"publisher","DOI":"10.1021\/jacs.7b10922"},{"key":"e_1_2_6_6_4","doi-asserted-by":"publisher","DOI":"10.1021\/acs.organomet.9b00809"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/cctc.201402119"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1039\/C8GC02186D"},{"key":"e_1_2_6_7_3","doi-asserted-by":"publisher","DOI":"10.1039\/C9GC03006A"},{"key":"e_1_2_6_7_4","doi-asserted-by":"publisher","DOI":"10.1021\/acscatal.0c00404"},{"key":"e_1_2_6_7_5","doi-asserted-by":"publisher","DOI":"10.1039\/D1SC00467K"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1039\/c39750000718"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1039\/D0EE03011B"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcou.2022.101963"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cej.2022.136185"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1039\/D1CY01713F"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1021\/om500832d"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1002\/adsc.201801323"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.catcom.2020.106125"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.inorgchem.1c02487"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/chem.202301915"},{"key":"e_1_2_6_15_1","volume":"1072","author":"Forster D.","year":"1971","journal-title":"J.
