![]() Born on a napkin sketchĪker Solutions started working on subsea compression back in 1985, when the technology “was born on a napkin sketch”, says Vesterkjaer. ![]() The Zeus system builds on the company’s pioneering subsea compression technology in use at Equinor’s Aasgard field offshore Norway and slated for Chevron’s Jansz-Io project offshore Western Australia. Zeus could also be used as a clean power source for subsea oil and gas field developments, delivering power to manifolds, wellheads and other power consuming equipment. Injection could also continue after production stops, potentially for third party users who require permanent CO 2 storage. Unlike power produced by renewables such as wind and solar, electricity generated by Zeus would be available at a constant rate, around the clock and 365 days a year.įield economics could even be improved, Vesterkjaer says, by using the CO 2 in an EOR application. We can deal with ‘problem’ gas with up to 70% CO 2 content,” he says. ![]() “The beauty is that you don’t need export-quality gas to generate power. Vesterkjaer says Zeus can use any gas as feedstock, including associated gas, methane hydrates, CO 2-rich gas and stranded gas. Meanwhile, 100 MW of emissions-free electricity would be sent via wire either to customers onshore or to offshore installations, where it could replace power generated by gas turbines. The carbon dioxide would be stored in a supercritical liquid state, meaning it could be pumped without the need for subsea compression.Īround 60 megawatts of the power generated on the seabed would be used by the air separation unit (ASU) housed on an offshore platform to produce the oxygen required for the unit - some 3200 tonnes per day for a 1 MMcmd-size Zeus facility. The base case Zeus facility envisages 1 million cubic metres per day of gas production, with 2300 tonnes per day - 885,000 tonnes per annum - of CO 2 captured and reinjected. The CO 2 is condensed and immediately injected back into the reservoir for permanent storage, with the power typically delivered to shore via subsea cable.
