Packaging bio-methane connections for the future Dan Anderson CEng 11th January 2012
The context • Utility bespoke design and build delivery model needs to evolve for the growth of renewable gas connections – approximately 250 biomethane injection plants will be required by 2020 to meet UK renewable energy targets. • Current approach: • Design and build cost is circa £650k for the injection plant (excluding connecting pipe and remote monitoring). • Lead time circa 12 months design and build (excluding remote monitoring point and remote monitoring).
The requirement • Need a pre-approved packaged design for biogas connections with suppliers on a call off contract to provide the built units to site • Key components: • Develop a fit for purpose cost-effective engineering specification for a packaged solution. • Develop a tender to source suppliers who can provide pre- approved packaged designs to meet the specification, which they can supply to site ready built. • Allow the concept to be future-proofed as ownership may not be with the GDN and regulatory requirements will change.

The outcomes • Packaged designs which can operate over the following operating conditions: • Pressure • Max inlet of 7 bar and Min outlet of 75mb • Flow • 20m3/h - 2000m3/h • Size • Equal in scale to a shipping container
The outcomes • Substantial cost saving • Lead times of 5-6 months (for supply to site) • Four suppliers are involved in the tender who can now be approached by DFOs/other GDNs should they wish to purchase a packaged unit. • Technica Ltd • Elster-Instromet • Orbital Gas Systems • Biogast/Future Energy Group Ltd • The work puts in place a platform for the industry to build from into the future.
