本レビューは、電化や水素直接利用が困難な産業（鉄鋼、化学等）における電解燃料の脱炭素化ポテンシャルを評価。生産プロセス、エネルギー需要、経済性、ライフサイクルGHG排出量を分析し、電解燃料は電力源次第で40～90%の排出削減が可能だが、高エネルギー消費やコストが課題と指摘。2030年までに水素製造コストが2.1ドル/kg以下に低下すれば競争力が向上する可能性を示す。
English
This review assesses electrofuels for decarbonizing hard-to-abate sectors (steel, chemicals, etc.) where electrification and direct hydrogen use are challenging. It analyzes production processes, energy demands, economics, and lifecycle GHG emissions, finding that electrofuels can reduce emissions by 40–90% depending on electricity source, but face high energy consumption and costs. Projected LCOH below $2.1/kg by 2030 could improve competitiveness. Key bottlenecks and research priorities are identified.

📄 Abstract（原文）
The decarbonization of hard-to-abate sectors remains a significant challenge in achieving net-zero emissions targets. These industries depend on energy-dense fuels, making direct electrification and the direct use of hydrogen technically and economically challenging. Electrofuels present a promising pathway to reducing emissions while leveraging surplus renewable energy. This review evaluates the feasibility of electrofuels for deep decarbonization, focusing on production processes, energy demands, and economic viability. Environmental performance is discussed in terms of lifecycle greenhouse gas (GHG) emissions, carbon circularity considerations, and energy conversion efficiencies, while techno-economic feasibility is evaluated using metrics such as levelized cost of hydrogen (LCOH), CO2 capture costs, and projected fuel production costs. The review indicates that while electrofuels can achieve substantial lifecycle emission reductions up to 40–90%, depending on pathway and electricity source, their deployment remains constrained by high energy demand, conversion losses, and capital costs. Projected reductions in LCOH to below $2.1/kg by 2030 and declining renewable electricity costs could significantly improve competitiveness, particularly in regions with abundant solar and wind resources. However, substantial trade-offs exist between efficiency, infrastructure compatibility, scalability, and carbon neutrality across different electrofuel routes. The review identifies key technological bottlenecks, cost drivers, and research priorities necessary to position electrofuels as a strategic solution for deep decarbonization in sectors where direct electrification is not feasible.
