| Abstract: |
The integration of a biomethanation system within a wastewater treatment plant for conversion of CO 2 and H 2 to CH 4 has been studied. Results indicate that the CO 2 could be utilised to produce an additional 13,420 m 3 /day of CH 4 , equivalent to approximately 133,826 kWh of energy. The whole conversion process including electrolysis was found to have an energetic efficiency of 66.2%. The currently un-optimised biomethanation element of the process had a parasitic load of 19.9% of produced energy and strategies to reduce this to <5% are identified. The system could provide strategic benefits such as integrated management of electricity and gas networks, energy storage and maximising the deployment and efficiency of renewable energy assets. However, no policy or financial frameworks exist to attribute value to these increasingly important functions. [ABSTRACT FROM AUTHOR] |
