It compresses carbon dioxide gas into a liquid state during periods of low electricity demand to store energy, then expands it back into gas to drive power turbines when demand peaks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike conventional pumped-hydro and compressed-air energy storage systems, the closed-loop technology does not require specific geological features such as mountains or underground caverns, offering a highly reliable, low-cost alternative for long-duration grid storage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Compressed carbon dioxide has a higher energy density and offers numerous advantages, including high efficiency, low cost, high safety and zero pollution, said Ma Guojiang, leader of the project.<\/em><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;The project&#8217;s designed efficiency makes it the most efficient carbon dioxide power generation unit in China today. Upon completion, the project is expected to generate approximately 200 million kilowatt-hours of electricity annually, saving 50,000 tons of standard coal and reducing carbon dioxide emissions by about 170,000 tons each year,&#8221; Ma said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The project is designed to stabilize the local power grid by absorbing excess electricity during off-peak hours and discharging it during demand spikes, helping integrate more renewable energy into the regional network.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Earlier,&nbsp;<a href=\"https:\/\/qazinform.com\/\">Qazinform<\/a>&nbsp;reported China&nbsp;<a href=\"https:\/\/qazinform.com\/news\/china-opens-worlds-first-large-scale-robot-theme-park-in-zhuhai-d1b257\">opened<\/a>&nbsp;the world&#8217;s first large-scale robot theme park in Zhuhai.&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>China connected its first 100-megawatt-class compressed carbon dioxide energy storage facility to the grid on&hellip;<\/p>\n","protected":false},"author":2,"featured_media":1930,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[9,2,5],"tags":[],"class_list":["post-1929","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-headline","category-project","category-tech"],"_links":{"self":[{"href":"https:\/\/en.esplaza.com.cn\/index.php\/wp-json\/wp\/v2\/posts\/1929","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/en.esplaza.com.cn\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/en.esplaza.com.cn\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/en.esplaza.com.cn\/index.php\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/en.esplaza.com.cn\/index.php\/wp-json\/wp\/v2\/comments?post=1929"}],"version-history":[{"count":1,"href":"https:\/\/en.esplaza.com.cn\/index.php\/wp-json\/wp\/v2\/posts\/1929\/revisions"}],"predecessor-version":[{"id":1931,"href":"https:\/\/en.esplaza.com.cn\/index.php\/wp-json\/wp\/v2\/posts\/1929\/revisions\/1931"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/en.esplaza.com.cn\/index.php\/wp-json\/wp\/v2\/media\/1930"}],"wp:attachment":[{"href":"https:\/\/en.esplaza.com.cn\/index.php\/wp-json\/wp\/v2\/media?parent=1929"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/en.esplaza.com.cn\/index.php\/wp-json\/wp\/v2\/categories?post=1929"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/en.esplaza.com.cn\/index.php\/wp-json\/wp\/v2\/tags?post=1929"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
