| | JULY - AUGUST 20259·Take advantage of the water depth for improving pressure difference and therefore energy storage capacity of the system.This PCS can be done in several ways and using pipelines, allow to take advantage of existing supply chain from Oil & Gas industry and therefore reach interesting cost levels.If pipelines already exist in the vicinity of the Offshore Wind Farm, we can repurpose them; this is the ROPES Product. In that case, CAPEX will be limited as we re-use existing pipelines. This will improve NPV as this will defer their decommissioning. In other hand, amount of energy will be driven by the available volume/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 "Bundle" 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 without taking up onshore space·New Generation + Storage Projects: utility-scale solution suitable for joint tenders requiring co-location of offshore wind and energy storage.· Decarbonisation of offshore O&G facilities: drives higher decarbonisation by safely delivering clean power· Green hydrogen Production: absorbs intermittency and improves electrolyser utilisation.
