OESTER
Offshore Energy Storage
Publieke samenvatting / Public summary
Aanleiding
The accelerating rollout of renewable energy system levels hurdles are starting to be thrown up that threaten its continuation. Grid congestion, system instability are caused by mismatch between variability of the renewables and demand either in time or location. If grid congestion arises a share of the generated electricity has to be curtailed. This decreases the utilisation of renewable energy reducing its potential to alleviate global emissions. Simultaneous production of electricity by multiple wind farms increases local supply, causing electricity prices in several markets to decline. Wind farm operators receive significantly lower revenues, also known as cannibalisation effect. These challenges can be mitigated through the introduction of energy storage systems (ESS) on the generation side. Co-located ESS can absorb electricity during high-production periods and release this energy during periods of low production or high demand, helping to stabilize supply and prices. Colocation offshore ES to support supply side multiple assets from generation to conversion and storage can be operated as a single unit, increasing the utilization of the offshore space and infrastructure.
Doelstelling
The core of the OESTER project is to mature, de-risk and validate offshore electricity storage options in relation with technology, market, environment, implemented in nature and society. The project supports the development of the next generation of offshore wind energy areas as baseload energy farms where wind, solar, electrical energy storage and potentially other types of electricity producing assets will be combined to enable higher capacity factor offshore power plants. Enabling new features and unlocking the full grid performance of these new types of renewable power plants. Different types of energy storage and different types of use cases for the storage “units” are investigated and matured towards full-scale commercial products that can be applied across the different markets.
Korte omschrijving
The project has 10 results and refer to the achieved five overarching project objectives: The activities related to the Objective 1 includes operational performance optimization strategies per storage option; concept engineering designs per technology; demonstration of a digital twin of the wind to storage technologies hybrid systems. The activities to achieve the objective 2 includes the technical, economical and environmental indicators for offshore projects, including the circularity, critical materials and CO2 footprint; eco-design and impact of marine life from installation to dismantling. The activities for objective 3 involves the techno economic viability for market implementation, legal and financial frameworks. The activities of objective 4 focus on a knowledge sharing platform and the creation of a digital atlas with the potential of storage offshore. Last objective involves project management and coordination activities.
Resultaat
The OESTER project has five overarching objectives. The Objective 1 consists of de-risking different technologies and developing new innovations for the short-term-, medium-, long-term duration offshore electricity storage. The Objective 2 focuses on creating eco-designed and sustainable storage projects nature inclusive, through different technical, economic and environmental indicators. CO2 footprint and Life Cycle analysis per storage option and the impact on the marine life, from the installation to the dismantling of the projects are aspects into consideration. The Objective 3 includes the requirements for implementing a commercially sustainable business case of the technology with wind in the market is assessed, addressing the commercial, regulatory and bankability of the offshore storage technologies. The Objective 4 focuses on the knowledge exchange, upscaling and governance. Wide scale implementation in space is assessed taking into account ecology and other offshore stakeholders. The Objective 5 includes the project coordination and stakeholder engagement through dissemination, communication and exploitation activities.
