電化が難しい航空・海運・バックアップ電源などに、水素に代わる液体燃料としてメタノールを最小限導入する「ミニマルメタノールバックストップ」を提案。欧州のエネルギーシステムモデルで分析し、水素ベースと比較して総システムコストが2.4%増（最大6.4%増）と小幅であり、インフラ複雑性の低減を考慮すれば妥当と結論づける。
English
This paper proposes a 'minimal methanol backstop' as a liquid fuel alternative to hydrogen for hard-to-electrify sectors like aviation, shipping, and backup power. Using a European energy system model constrained to carbon neutrality, it shows that methanol-based systems increase total system costs by only 2.4% relative to hydrogen systems, with a maximum increase of 6.4% across sensitivities, arguing this premium is justified by reduced infrastructure complexity.

日本のGX文脈において
日本は水素・アンモニアに加え、メタノールも注目すべき選択肢となる。本稿のコスト比較手法やインフラ簡素化の議論は、日本の燃料戦略やSSBJ開示におけるシナリオ分析に示唆を与える。
In the global GX context
This work enriches the global debate on hydrogen vs alternative fuels for hard-to-abate sectors, which is central to transition finance and ISSB-aligned scenario analysis. It provides quantitative evidence that methanol can be a cost-competitive backstop, relevant for corporate disclosure pathways.
👥 読者別の含意
🔬研究者:Energy system modelers can use the methanol backstop concept as a benchmark for comparing fuel alternatives in hard-to-electrify sectors.
🏢実務担当者:Corporate sustainability teams in shipping, aviation, or power generation can assess methanol as a viable decarbonization option with modest cost impact.
🏛政策担当者:Policy offices can consider methanol as a complementary fuel to hydrogen for residual demand, reducing infrastructure complexity and lock-in risks.
📄 Abstract（原文）
<h2>Summary</h2> Electrification of sectors such as land transport and building heating is a cost-effective pathway to deep decarbonization. However, some sectors still require energy-dense fuels—including aviation, shipping, and backup power—or chemical feedstocks. Although a "hydrogen economy" is often proposed to fill these hard-to-electrify gaps, it faces challenges in transport, storage, and infrastructure coordination. We introduce a "minimal methanol backstop" to supply residual demand in highly electrified systems. As a liquid fuel, methanol is easy to store and transport and avoids infrastructure lock-in. Produced from hydrogen and carbon monoxide, it can help integrate biogenic carbon from decentralized biomass wastes and residues. Using a European energy system model constrained to be carbon-neutral, we show that methanol-based systems increase total system costs by 2.4% relative to hydrogen-based systems, an increase that remains below 6.4% across sensitivities. We argue that this modest cost premium is justified by reduced infrastructure complexity.
