本研究は、ナイジェリア・アブジャの農村一次医療センター向けに、風力・太陽光発電と水素貯蔵を組み合わせたオフグリッドシステムを設計・評価した。HOMER Proを用いた解析により、エネルギー均等化コスト2.53ドル、純現在価格134,123ドルを達成し、25年間の全負荷を満たすことが示された。余剰電力で水素を製造し、不足時に燃料電池で電力を供給するシステムの実現可能性を実証している。
English
This study designs and evaluates an off-grid hybrid renewable energy system with green hydrogen storage for a rural primary healthcare center in Abuja, Nigeria. Using HOMER Pro, the system achieves a Levelized Cost of Energy of $2.53 and Net Present Cost of $134,123, meeting all load requirements over 25 years. Excess renewable energy is used for hydrogen production, which is then used to power the facility when renewables are insufficient.

📄 Abstract（原文）
The Sustainable Development Goal, SDG No. 3 of the UN, is to develop healthcare for all. Nigeria's healthcare policy is to make primary healthcare the bedrock of the national healthcare system. A dearth of access to electricity is the most critical impediment to quality healthcare delivery in Nigeria. Fragile and inadequate capacity has bedevilled the national grid, making connection to the grid either impossible or ineffective. Out of the over 34,000 Primary Healthcare Centres in the country, 40% lack access to any form of electricity. Renewables are being used to meet the electricity demand in rural and isolated communities. The present study investigates wind and solar renewable energy resources in Abuja with a view to generating electricity that will be sufficient to power a typical rural healthcare centre, while the excess renewable energy is used for hydrogen production that will later be used to power the healthcare centre when the renewable resources are unavailable or inadequate. A wind energy conversion system, solar PV, and electrolyser-hydrogen tank-fuel cell configuration were designed to meet the electrical load at the primary healthcare centre. In situ and satellite-based meteorological data were assessed. Weibull and Logistic distributions were used to assess resource availability. Homer Pro was used for the design of the off-grid system. The Levelized Cost of Energy and Net Present Cost of Energy were found to be $2.53 and $134,123, respectively. The system was able to meet all the load requirements for the 25 years, with an annual excess electricity is 3,179kWh and 2.02kWh of unmet load and a capacity shortage of 4.08kWh.
