About the project

The FlexMeOH project aims to enable highly flexible e-methanol production systems that can efficiently operate under variable renewable electricity supply. The project focuses on improving flexibility across key subsystems, including electrolyzer technologies (PEM, SOE, and alkaline), energy storage solutions, electricity market interactions, and methanol synthesis processes. Dynamic models of 100-MW scale e-methanol plants will be developed to evaluate operational flexibility, including start-up, load transitions, and standby modes. Experimental studies on PEM and solid oxide electrolyzers will investigate the impacts of dynamic operation and identify optimal operating strategies. Based on these results, plant-wide dynamic operation strategies will be developed and evaluated through techno-economic analyses under European electricity market conditions.

Current e-methanol production systems are primarily designed for steady-state operation and lack the capability to operate efficiently under fluctuating renewable electricity supply. Key challenges include limited understanding of dynamic operation impacts on electrolyzers, insufficient plant-wide flexibility, and the lack of integrated strategies linking e-fuel production with electricity markets. FlexMeOH addresses these challenges by developing dynamic models and experimental validation for multiple electrolyzer technologies (PEM, SOE, and alkaline), integrating storage systems and flexible plant design, and establishing plant-wide operational strategies. By combining subsystem modelling, experimental testing, and electricity market analysis, the project will deliver a new framework for flexible and market-responsive e-methanol production systems beyond the current state of the art.

FlexMeOH will deliver validated strategies for flexible and cost-efficient e-methanol production under variable renewable electricity supply. The project will develop dynamic models of large-scale e-methanol plants, experimental insights into electrolyzer operation under dynamic conditions, and optimized plant-wide control strategies linked to electricity market participation. These results will enable more reliable and economically viable e-fuel production and support the integration of renewable electricity into Power-to-X systems. The project will contribute to the development of scalable and regulation-ready e-methanol technologies, supporting decarbonisation of hard-to-abate sectors such as maritime transport, aviation, and chemical industries, while enhancing grid flexibility and renewable energy utilization across Europe.
