ナイジェリアのセメント、鉄鋼、化学産業を対象に、LEAPモデルを用いて2060年までのエネルギー需要とGHG排出を4シナリオで推計。グリーン燃料シナリオではセメントで61%減、化学で79.6%減となる一方、鉄鋼は電化・水素化でも13%増と、部門ごとに異なる対策が必要と示す。
English
Using the LEAP model, this study projects energy demand and GHG emissions to 2060 for Nigeria's cement, iron/steel, and chemical sectors under four scenarios. Results show sector-specific responses: green-fuel pathways cut cement demand by 61% and chemicals by 79.6%, but iron/steel demand still rises 13% due to electrification and hydrogen-based routes. A uniform policy is ineffective; differentiated strategies are needed.

📄 Abstract（原文）
Nigeria's cement, iron and steel, and chemical industries account for a substantial share of the country's industrial energy use. This study applies the Low Emissions Analysis Platform (LEAP) to project industrial energy demand and greenhouse gas emissions to 2060 under four scenarios: a Baseline reflecting current trends; a Realistic Scenario based on existing policy commitments; a Light-Fossil (LF) pathway; and a Green-Fuel (GF) pathway assuming widespread adoption of carbon capture and storage (CCS), electric arc furnaces, and hydrogen. The three subsectors respond differently to the same assumptions. Cement shows the widest range of outcomes: energy demand falls by 61%, from 60.5 million gigajoules (GJ) in 2015 to 23.55 million GJ in 2060, under the GF pathway, but rises by 522% to 376.78 million GJ under the Realistic Scenario, which assumes continued reliance on conventional clinker production. The chemical sector is the most responsive to fuel switching, with demand falling by 79.6% under GF conditions, compared with a 259% rise in the Baseline. Iron and steel are an outlier: even under GF assumptions, energy demand rises by approximately 13% to 36.60 million GJ by 2060 because electrification and hydrogen-based direct-reduction routes change the source of energy rather than eliminate the need for it. These results indicate that a uniform decarbonisation policy is unlikely to serve Nigeria's industrial sector effectively. Cement decarbonisation depends on CCS deployment and clinker substitution, chemical-sector decarbonisation on electrification and green-hydrogen feedstocks, and iron and steel decarbonisation on a slower, technology-led transition supported by a more reliable grid. The findings provide a sector-differentiated basis for prioritising investment and policy under Nigeria's Energy Transition Plan and its 2060 net-zero target.
