As the world faces increasing water usage and droughts caused by climate change, many countries are turning to desalination plants to secure their water supplies. However, these plants come with environmental concerns, including high energy consumption and the release of toxic brine into the ocean. In an effort to address these issues, a startup called Capture6 has announced plans to build a carbon-capture facility in South Korea. This facility will work in conjunction with a nearby desalination plant to capture carbon dioxide and store it in desalination brine. In addition, Capture6 claims it can extract fresh water from the brine, further enhancing its sustainability and potential for profit. This venture, known as Project Octopus, aims to reduce greenhouse gas levels, provide new sources of fresh water, and minimize the environmental impact of desalination. However, there are still challenges to overcome, such as energy consumption and efficient water production. Despite these challenges, Capture6 is confident in its ability to revolutionize the water sector with its innovative technology.
