This study focused on the modelling and optimization of hydrogen storage integrated with combined heat and power plants and rooftop photovoltaic systems in an energy system in central Sweden. Three different scenarios (S0–S2) were designed to investigate the impacts on the system flexibility and operational strategy.
A large share of the power stored as hydrogen is surplus power generated from the rooftop PV systems. Therefore, the operational strategy of the hydrogen storage system is similar to that of the storage in scenario S1. However, on several occasions, the amount of power to hydrogen is decreased due to reduced supply from thermal plants.
The regional energy system including the CHP plants and heat-only boilers integrated with rooftop PV systems and power-to-gas storage is considered as the reference scenario. The other scenarios are described to investigate the potential of the hydrogen storage and the fuel cell application to meet the deficit of power supply in the system.
The results indicate that the proposed storage system increases the system flexibility and can reduce power imports and the marginal emissions by around 53%, compared with the current energy system. There is a potential to convert a large amount of excess power to hydrogen and store it in the system.
According to results from previous studies, the integration of rooftop PV into the regional energy system without power-to-gas storage reduces the total power import to the region by more than 40% . However, the power supply profile from the proposed system varies over the studied year.
Comparing the results for the power storage in all scenarios reveals that the increased capacity of the storage installation in the systems in scenarios S1 and S2 contributes to the increased power storage in the form of hydrogen.
The European energy storage market is booming with Germany leading residential adoption (+58% YoY) thanks to €500/kWh subsidies. Italy's new tax credits drive 5.2GWh commercial deployments, while UK grid-scale projects exceed 8GWh with 2-hour duration systems. Key selection criteria: German-certified safety (VDE-AR-E 2510), 10+ year warranties, and VPP readiness. Top-performing products include Sonnen's hybrid inverters (98% efficiency) and BYD's Blade Battery (12,000 cycles @80% DoD). For snowy regions like Scandinavia, consider Huawei's -30°C compatible systems. France mandates carbon footprint declarations - Sungrow's ISO-14067 certified solutions gain preference.
For European homeowners, 5-10kWh systems with 3-phase compatibility are ideal. Top picks: 1) Tesla Powerwall 3 (13.5kWh, 97% round-trip efficiency) for smart home integration; 2) LG Chem RESU Prime for compact urban installations; 3) SMA Sunny Boy Storage for retrofit projects. Critical features: EU-made battery cells (exempt from CBAM tariffs), dynamic tariff optimization (like Octopus Energy integration), and fire-safe LiFePO4 chemistry. Southern Europe demands 85%+ depth of discharge capability, while Nordic markets require -25°C operation. Always verify CEI 0-21 compliance for Italian grid connection and EnWG certification for German feed-in.
