欧州25カ国を対象に、住宅用蓄電池の普及を4種類の電気料金制度下でモデル化。自己消費型では投資収益が弱く2050年時点の容量は356～424GWhに留まるが、系統連系を促す高度な料金設計では530GWh超に拡大。放電量は65TWhから168TWhへ増加し、排出削減は年間6.1～8.6MtCO2と推定。分散型蓄電の統合には料金設計が重要と示す。
English
Modeling residential battery diffusion across 25 European countries under four tariff designs, this study finds self-consumption yields weak returns (356-424 GWh by 2050), while advanced tariffs enabling grid interaction raise capacity above 530 GWh. Discharge rises from 65 to 168 TWh, with annual emissions savings of 6.1-8.6 Mt CO2-eq, highlighting tariff design's role in integrating distributed storage.

📄 Abstract（原文）
<title>Abstract</title> <p>Europe’s transition to a low-carbon energy system is reshaping household electricity generation, consumption, and storage. Residential batteries can increase rooftop photovoltaic self-consumption, support energy autonomy, and provide grid benefits when operated in a coordinated manner. This study applies the Clean Energy Adoption in the Residential Sector (CLEARS EU) model to project residential battery diffusion under four electricity tariff designs of increasing complexity and to assess their grid-level impacts across 25 European countries. The model combines net present value calculations with Bass diffusion dynamics to capture financial and behavioural drivers of adoption. Results show that tariff design strongly affects battery profitability and diffusion. Under self-consumption, investment returns remain weak in some large potential markets, limiting residential battery capacity to 356–424 GWh by 2050. More advanced tariff designs that allow grid interaction and benefit from rapid cost reductions raise projected capacity above 530 GWh. Battery operation also determines system impacts: annual discharge rises from about 65 TWh under self-consumption to 168 TWh with peak-hour feed-in, while coordinated flexibility can reduce peak-load pressures. Estimated emissions savings range from 6.1 to 8.6 Mt CO₂-eq annually. The findings underline the importance of advanced tariff design for integrating distributed storage and supporting power-sector decarbonisation.</p>
