PROJECT OVERVIEW
ENEOS Corporation constructed a demonstration plant at Bulwer Island, Brisbane, to produce methylcyclohexane (MCH), a liquid carrier of hydrogen at atmospheric pressure and temperature, using its proprietary low-cost "electrochemical synthesis of organic hydride" method. The opening ceremony was held 30 January 2023 and the plant began operating a month later in February.
The demonstration plant produces green MCH by powering an electrolyzer with a 250-kilowatt solar power system. With the aim of maximising production efficiency, the plant confirmed the durability of the electrolyzer under subtropical conditions as well as developed optimal operation and control technologies for it when plant operation is adjusted to match fluctuations in solar power. The plant operations were conducted from February to September 2023.
ADDED VALUE
Phase 1
GRPS were engaged by ENEOS to provide Operations Readiness (risk assessments, procedures, processes implementation, and team competence) and Commissioning services towards the end of the construction phase of the facility. GRPS were also engaged to operate and maintain the Green Hydrogen facility under GRPS management systems to ensure regulatory compliance. At completion of the demonstration phase, the plant was decommissioned.
Phase 2
GRPS is continuing its Operations and Maintenance services contract with ENEOS Group as the Direct MCH® Demonstration Plant moves into Phase 2. Phase 2 commenced in June 2026 and is currently active, testing additional technologies and scaling to larger production volumes. Building on the operations readiness, commissioning, and regulatory compliance work delivered in Phase 1, GRPS continues to bring a strong focus on safety and compliance as the project scales up.
