本論文は、航空・海運・バックアップ電源など電化が困難なセクター向けに、メタノールを液体燃料として利用する「最小限の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を用いて、水素ベースと比較し総システムコストが2.4%増加するにとどまることを示し、インフラ複雑性低減を考慮すれば許容範囲と主張する。
English
This paper proposes a 'minimal methanol backstop' as a liquid fuel for hard-to-electrify sectors like aviation, shipping, and backup power. Using a European energy system model, it finds methanol-based systems increase total system costs by only 2.4% relative to hydrogen-based systems, arguing this modest premium is justified by reduced infrastructure complexity.

📄 Abstract（原文）
In this Zenodo repository, we store the solved PyPSA networks used in the analysis of the paper "A minimal methanol backstop for high-electrification scenarios" published in Joule ( 10.1016/j.joule.2026.102464 ). Additionally, we provide csv files for all scenarios containing the figures for the energy balances, installed capacities, CAPEX and OPEX. Summary 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. While 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.
