本論文は、バイオCO2由来の再生可能メタンが欧州のエネルギー移行において制度的に曖昧な位置にあることを指摘する。技術的には成熟しているが、RED IIIのRFNBO枠組みでは電力由来の水素やe-fuelが優先され、バイオCO2由来メタンは制度的に認識されにくい。この非対称性は技術的成熟度ではなく、制度的・歴史的要因に起因すると論じる。
English
This paper examines the institutional ambiguity of renewable methane derived from biogenic CO2 in Europe's energy transition. Despite technological maturity, the RED III framework privileges electricity-based fuels like hydrogen and e-fuels, leaving bioCO2-derived methane institutionally less recognized. The authors argue this asymmetry stems from historical and conceptual governance foundations rather than technological readiness.

📄 Abstract（原文）
ABSTRACT Renewable methane derived from biogenic CO 2 (bioCO 2 ) occupies a paradoxical position within Europe's energy transition. BioCO 2 ‐to‐methane conversion is supported by a technologically credible portfolio of biological, catalytic, and hybrid routes. However, commercial maturity remains uneven across pathways, whereas institutional recognition is still ambiguous, particularly within the framework of the Renewable Energy Directive (RED III) and its provisions for Renewable Fuels of Non‐Biological Origin (RFNBOs). This ambiguity cannot be explained by technological readiness alone, but it reflects the historical and conceptual foundations through which different renewable fuel families have been governed in Europe. Electricity‐based pathways, such as renewable hydrogen and hydrogen‐derived synthetic fuels (e‐fuels), have co‐evolved with regulatory frameworks that prioritize controllability, verifiable links to renewable electricity inputs, and digital traceability. These characteristics align closely with the epistemic assumptions embedded in RFNBO provisions. In contrast, renewable methane from biogenic CO 2 (hybrid bioelectrochemical methane) originates from a distinct lineage rooted in biological processes, territorially embedded infrastructures, and circular‐economy practices associated with agriculture, waste management and anaerobic digestion. As a result, it remains institutionally indeterminate not because of missing rules, but because existing governance architectures privilege electricity‐centric fuel pathways, leaving bioCO 2 ‐derived methane only partially legible within current regulatory categories. This perspective adopts a cross‐fuel conceptual approach, treating hydrogen, e‐fuels, and renewable methane as institutional cases rather than technical options. Systemic readiness levels are used as an interpretative lens to situate renewable methane beyond technological maturity, highlighting the role of institutions, infrastructures, and processes of societal and institutional recognition in shaping its recognition within Europe's evolving energy system.
