The device uses a 14-millimeter piece of porous glass foam soaked in sulfuric acid to capture water from the air; the liquid then runs off to the electrodes, which separate it into oxygen and hydrogen. Based on a technique known to experts as direct air electrolysis, the device functioned with an efficiency close to 95% for 12 consecutive days, powered by solar and wind energy, and can even operate in dry environments with a humidity of just 4%. It was developed with the aim of eliminating the limitations of other methods of hydrogen extraction, which produce unwanted chemical compounds, result in low-purity hydrogen, are inefficient, or require an extra step to separate the components of the water (<em>Nature Communications<\/em>, September 6).<\/p>\n","protected":false},"excerpt":{"rendered":"Prototype electrolyzer produces hydrogen from air with no need for water","protected":false},"author":475,"featured_media":465972,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[1651],"tags":[207,227],"coauthors":[785],"class_list":["post-465971","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-notes","tag-bioenergy","tag-energy"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/465971","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/users\/475"}],"replies":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/comments?post=465971"}],"version-history":[{"count":1,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/465971\/revisions"}],"predecessor-version":[{"id":465976,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/465971\/revisions\/465976"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media\/465972"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=465971"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=465971"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=465971"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=465971"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
