Survivability assessment, cost redUction pathways and eNvironmental evaluation of offshoRe Installed floating Solar energy farms

欧洲目前正从依赖俄罗斯天然气过渡到2050年完全可再生、可靠和低成本的能源系统。为了实现这一目标，大规模的可再生能源项目至关重要。然而，这种转变受到几个因素的限制，例如陆上空间的可用性，以部署GW规模的项目，供应链中断以及各种利益相关者对视觉污染和空间使用的担忧。到2050年，海上浮动光伏（OFPV）可以在欧洲提供数百个GW，同时解决上述挑战。在海上风电快速发展的地区（如北海），OFPV可以与多源风电场内的风力相结合。这使得每平方公里的能源提取量增加了9倍，并且由于满载小时数增加了10-20%而更好地利用了基础设施，同时为其他利益相关者留下了空间，因为相同数量的电力生产需要更少的风电场和电力基础设施。在地中海和黑海的部分地区，风力资源较低，独立的OFPV也有助于实现可再生能源的高渗透率。航海日出将消除OFPV提供这些好处的最后障碍。一个5兆瓦的并网，多年的海上示范的高度竞争力的OFPV系统及其组件内的商业风力发电场将提供所需的信任升级的技术。在演示之前，它的技术可靠性将通过实验室测量，波浪风槽测试和建模研究在最极端的条件下进行验证。通过设计改进实现的成本降低将在具体的业务案例中量化，并应使LCOE <148 €/ MWh，使OFPV在财务上可行。此外，OFPV示范的测量活动、大规模环境建模和生命周期评估（包括循环性）将有助于了解对环境的总体影响。

Europe is currently in a transition away from its dependency on Russian gas towards a fully renewable, reliable, and low-cost energy system by 2050. To achieve this target, large-scale renewable energy projects are essential. However, the transition is limited by several factors such as onshore space availability to deploy GW-scale projects, supply chain disruptions, and concerns from various stakeholders around visual pollution and space use. Offshore floating PV (OFPV) can deliver hundreds of GWs in Europe by 2050 while resolving above challenges. In areas with a fast-expanding offshore wind sector (e.g. North Sea), OFPV can be combined with wind inside multi source farms. This enables the extraction of up to 9x more energy per km2 and better utilization of the infrastructure due to 10-20% more full-load hours, while leaving space for other stakeholders as fewer wind parks and electrical infrastructure are needed for the same amount of electricity production. In parts of the Mediterranean and the Black Sea with low wind resources, also stand-alone OFPV can help to achieve high penetration of renewable energy. Nautical SUNRISE will remove the last barriers of OFPV to deliver these benefits. A 5 MW grid-connected, multi-year offshore demonstration of a highly competitive OFPV system and its components inside a commercial wind farm will provide the trust needed for the upscaling of the technology. Prior to the demonstration, itstechnical reliability will be validated in the most extreme conditions through laboratory measurements, wave-wind tank tests, and modelling studies. The cost reduction achieved through design improvements will be quantified in concrete business cases and should enable an LCOE of <148 €/ MWh, making OFPV financially viable. Additionally, the measurement campaign at the OFPV demonstration, large-scale environmental modelling, and life-cycle assessment including circularity will help to understand the overall effect on the environment.
