September - 202319volume/pressure in pipeline which cannot reach the required storage level to optimise the electricity production of the wind field.If no pipeline exists around, an optimised Energy storage system can be installed along the wind farm: Power Bundle. This combines a well-known O&G pipeline system called "Bun-dle" which consists onshore prefabricated stack of pipelines ended with structures including valves, controls and sensors; submerged towed on site and landed on seabed This methodology does not require any heavy lift vessels and can be done on large weather windows. This is why it is widely used in North Sea locations.Those 2 systems are developed and commercialised by Flasc and Subsea 7 companies and are utility scale energy storage solutions. They have been recently awarded by UK BEIS Grant funding for a detail engineering of a demonstrator and several engagements are ongoing with Wind Farm developers. The benefits of this Utility scale energy storage are: · Existing Offshore Wind Farms: increases asset utilisation with-out taking up onshore space.· New Generation + Storage Projects: utility-scale solution suit-able for joint tenders requiring co-location of offshore wind and energy storage.· Decarbonisation of offshore O&G facilities: drives higher de-carbonisation by safely delivering clean power.· Green hydrogen Production: absorbs intermittency and im-proves electrolyser utilisation. PCS can be done in several ways and using pipelines, allowing to take advantage of existing supply chain from Oil & Gas industry and therefore reaching interesting cost levels
