Clean Energy Systems Inc. (CES), PETRONAS, MISC Berhad (MISC), and Aker Solutions AS (AKSO) have officially signed an agreement for the ZEUS Demo Front-End Engineering and Design (FEED), marking a pivotal step in the development of the Zero Emission Power Station ( ZEUS ) project. The agreement was formalized at the Energy Asia 2025 Conference in Kuala Lumpur. ZEUS represents a breakthrough in zero-emission power generation, leveraging CES’ high-pressure oxyfuel-based thermal technology with integrated CO₂ capture and repurposing. The FEED phase aims to demonstrate ZEUS’ ability to generate dispatchable, zero-emission power using high-CO₂ natural gas streams, transforming previously stranded gas reserves into sustainable energy sources. Once validated, the technology may be scaled up for both onshore and offshore deployment, including floating power applications. Petronas Vice President of Group Technology & Commercialization, Izwan Ismail said “ZEUS represents more than a technology demonstration — it is a bold statement of PETRONAS’ unwavering commitment to a low-emission, sustainable future. Beyond its technical capabilities, ZEUS fosters innovation ecosystems and expedites the delivery of sustainable solutions, awakening possibilities for our upstream business. We are collaborating with the right partners to accelerate the delivery of this solution.” Mark McGough, CEO of Clean Energy Systems said, "The ZEUS project showcases the unmatched capabilities of CES’ proprietary platelet burner technology to deliver zero-carbon, zero-NOx power solutions at scale. This achievement demonstrates how our high-pressure oxy-combustion systems can reliably convert a wide range of gases into clean, dispatchable energy. Scaling this technology for ZEUS marks a significant milestone, not only for CES but for the advancement of zero-emission power generation globally." Zahid Osman, President & Group CEO of MISC, said “The ZEUS project demonstrates how we are putting our #deliveringProgress mission into action, harnessing innovation to deliver more energy with less emissions. By integrating cutting-edge carbon capture technology with adaptable maritime solutions, we are not just advancing sustainable power generation but also unlocking new possibilities for stranded gas resources. The signing marks a progressive step forward for the team and exemplifies how partnerships can turn bold ideas into impactful solutions. MISC is proud to collaborate and leverage our maritime expertise to advance this technology for offshore deployment, supporting both Malaysia’s and the world’s transition to a lower-carbon future.” Jo Kjetil Krabbe, Executive Vice President of Power Solutions at Aker Solutions, emphasized the importance of robust engineering and effective system integration as the project moves into its next phase. “We look forward to turning proven components into an integrated system that works at scale, and with zero emissions. Aker Solutions’ role is to ensure that the design is technically robust, that interfaces are well managed, and that the system can be built and operated reliably. Together with PETRONAS Research and MISC Berhad, we’re taking an important step toward making ZEUS ready for deployment in demanding operational environments.” The partners share a clear ambition: to deliver sustainable, and affordable zero-emission power solutions that support the global energy transition.
