HySynergy e-Methanol

Challenge

e-Methanol can be produced by combining hydrogen produced via electrolysis from renewable energy sources with CO2 and potentially other light carbon-containing gases in a hydrogenation reaction over a suitable catalyst. CO2 is a waste product from combustion, but also a by-product when waste materials are converted into fuels in a hydrothermal liquefaction process, which is a sustainable alternative method for producing future fuels. Therefore, we wish to leverage the synergy that can be established between Everfuel's electrolysis plant in Fredericia (HySynergy) and Crossbridge Energy A/S’s refinery, which is undergoing a green transformation.

Solution

The project is intended to be executed partially as a physical project, where a small demonstration setup will be established with the goal of producing advanced fuels. In addition to this physical test project, two theoretical projects will be executed. One project will explore the compatibility between an electrolysis plant and a methanol plant, investigating potential start-up and shutdown times and the possible need to store hydrogen. Furthermore, synergies between different electrolysis technologies will be examined to map the advantages and disadvantages of various technologies. The second theoretical project will be a techno-economic study to map the costs of establishing and operating a methanol production facility. Specific challenges, such as the benefits/challenges of storing energy as hydrogen versus methanol, will also be investigated.

Impact

By August 2023, the project will have demonstrated the possibilities and potential of establishing a methanol plant with a capacity of 100 metric tons per day, powered by Everfuel and Crossbridge Energy A/S. Technical challenges for the specific project will highlight the management of flue gas quality in a way that ensures the lifespan of the catalysts in the plant and, thus, keeps operating costs at an acceptable level. Additionally, the compatibility between an e-methanol plant and other plants such as electrolysis facilities and co-processing plants will be explored to identify the best technological and cost-effective integration between the plants involved.
