System description and mathematical modelling The structure of the integrated island energy system is illustrated in Fig. 1. It primarily consists of a wind power generation system, photovoltaic power generation system, energy storage system, hydrogen system, and auxiliary power generation system.
An energy island makes it possible to establish large wind farms at sea far from the coast. The energy produced by the wind turbines is sent via cables to the energy island, from where it is sent out to consumers. On Bornholm, a high-voltage facility must therefore be established on the island which can receive and distribute the electricity.
The study suggests that interconnecting smaller island systems can provide significant benefits, including reduced energy costs and improved reliability. Reunion Island has set an ambitious goal to achieve 100% renewable energy by 2030, using a comprehensive approach that combines solar, wind, and advanced energy storage technologies.
EnergyPLAN is well suited for integration of large share of renewables in island energy systems, as 13 studies are known for 100% RES analyses on islands using EnergyPLAN , such as , , , .
3.2. Energy Storage Technologies and Their Role in Island Energy Systems Energy storage is widely recognized as a crucial facilitator of high renewable energy penetration in island systems [70, 71]. This thematic area explores different storage solutions, including BESSs, hydrogen storage, PHS, and flywheels.
In addition to the land-based converter station in Bornholm, a similar plant must be constructed in Zealand to receive the power from the energy island. Also, a separate energy island is expected to be built in the North Sea.
The global residential solar storage and inverter market is experiencing rapid expansion, with demand increasing by over 300% in the past three years. Home energy storage solutions now account for approximately 35% of all new residential solar installations worldwide. North America leads with 38% market share, driven by homeowner energy independence goals and federal tax credits that reduce total system costs by 26-30%. Europe follows with 32% market share, where standardized home storage designs have cut installation timelines by 55% compared to custom solutions. Asia-Pacific represents the fastest-growing region at 45% CAGR, with manufacturing innovations reducing system prices by 18% annually. Emerging markets are adopting residential storage for backup power and energy cost reduction, with typical payback periods of 4-7 years. Modern home installations now feature integrated systems with 10-30kWh capacity at costs below $700/kWh for complete residential energy solutions.
Technological advancements are dramatically improving home solar storage and inverter performance while reducing costs. Next-generation battery management systems maintain optimal performance with 40% less energy loss, extending battery lifespan to 15+ years. Standardized plug-and-play designs have reduced installation costs from $1,200/kW to $650/kW since 2022. Smart integration features now allow home systems to operate as virtual power plants, increasing homeowner savings by 35% through time-of-use optimization and grid services. Safety innovations including multi-stage protection and thermal management systems have reduced insurance premiums by 25% for solar storage installations. New modular designs enable capacity expansion through simple battery additions at just $600/kWh for incremental storage. These innovations have improved ROI significantly, with residential projects typically achieving payback in 5-8 years depending on local electricity rates and incentive programs. Recent pricing trends show standard home systems (5-10kWh) starting at $8,000 and premium systems (15-20kWh) from $12,000, with financing options available for homeowners.
