For this project, power will be generated by a modified NOMAD buoy and transmitted to the seafloor battery through an electrical-optical-mechanical umbilical cable.<\/p>\n\n\n\n<p>The 225 kWh battery will be protected from the ocean environment by a sealed, one-atmosphere housing attached to a mud mat, deployed at a depth of 50 m and approximately 2 miles offshore at the PacWave North site, near Newport Oregon. This system will be capable of powering other devices on the seafloor, as well as supporting communications to shore via a cellular connection from the NOMAD buoy.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"817\" height=\"717\" src=\"https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/4109\/files\/2021\/01\/Seafloor_Battery.png\" alt=\"\" class=\"wp-image-196\" style=\"width:409px;height:359px\" srcset=\"https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/4109\/files\/2021\/01\/Seafloor_Battery.png 817w, https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/4109\/files\/2021\/01\/Seafloor_Battery-300x263.png 300w, https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/4109\/files\/2021\/01\/Seafloor_Battery-768x674.png 768w\" sizes=\"auto, (max-width: 706px) 89vw, (max-width: 767px) 82vw, 740px\" \/><figcaption class=\"wp-element-caption\">Seafloor Power Vault housing and mud mat (provisional).
