英国における太陽光・風力と水素貯蔵の組み合わせが、従来のナショナルグリッドよりも低コストで電力を供給できることを示す。適切な規模のサイトで3～4年の投資回収が可能であり、10年で約6000万ポンドの節約効果が見込まれる。
English
This paper demonstrates that combining solar, wind, and hydrogen storage can deliver electricity at less than half the cost of the UK National Grid. With a payback period of 3-4 years and estimated savings of £60M per site over ten years, it advocates for properly scaled local renewable energy projects with grid backup.

日本のGX文脈において
英国の事例ではあるが、日本の地域エネルギー自給や水素社会構想にも示唆を与える。特に、太陽光・風力の変動を水素貯蔵で補完するモデルは、日本の再生可能エネルギー導入拡大の参考となる。
In the global GX context
While UK-specific, this paper offers a practical model for integrating hydrogen storage with solar and wind at a community scale. It contributes to the global discourse on cost-effective renewable energy systems and the role of hydrogen in grid stabilization.

📄 Abstract（原文）
The objective of this paper is to show that local renewable energy in Britain can compete well with the traditional National Grid and deliver costs that are less than half the current prices. First, the history of green electricity originally invented in England is summarized. Then the high prices of electricity in Britain are defined, showing that reduced costs are now possible through renewables because the UK monopoly National Grid is past its peak. Renewables, such as Solar and Wind, fluctuate and are not 100% available, suggesting that big energy storage is necessary, yet this has never been properly integrated into the National Grid. Hydrogen is the best molecule for storing and transporting energy in a composite tube trailer carrying 33MWh typically. When combined with solar panels and a large wind turbine, energy generation is in excess that can be converted to hydrogen stored in composite cylinders, filling renewable generation gaps with Combined Heat and Power (CHP) from zero emission fuel cells. An example of a large village site approaching this concept is described in detail, though failing in several aspects. The conclusion is that Solar plus Wind plus Hydrogen energy storage can be successful if the site scale is correct, such that appropriate solar/wind/hydrogen generation is installed, and the Grid is connected for back-up of the private wire system. Payback time of 3 to 4 years and savings on energy bills near £60M for each site over ten years should incentivize this innovation.
