本論文は、固体酸化物電解セルを用いた水素生産を統合した地域エネルギーシステムの技術経済分析を実施。水素、酸素、二酸化炭素削減・回収の均等化コストをパラメトリックに分析し、プロジェクトの代替案が特定の市場に適していることを示す。自家生産では炭素価格不要だが、購入水素では$209/tCO2e以上の炭素価格が必要など、多機能システムの経済性評価には全製品のコストを組み合わせて評価する必要があることを実証。
English
This paper conducts a technoeconomic analysis of a district energy system integrating hydrogen production via solid oxide electrolysis. It parametrically analyzes levelized costs for H2, oxygen, and CO2 abatement/capture. Findings show self-production requires no carbon pricing if oxygen revenues are high, while purchased H2 requires carbon prices above $209/tCO2e. The work demonstrates the necessity of evaluating combined levelized costs of all products for multifunctional systems.

In the global GX context
This paper provides a detailed technoeconomic framework for evaluating hydrogen integration in district energy, with policy-relevant insights on carbon pricing thresholds. Globally, it contributes to the literature on hydrogen economics and CCUS, especially the interplay between hydrogen production, carbon pricing, and revenue from byproducts, which is relevant for countries developing hydrogen strategies.

📄 Abstract（原文）
Hydrogen (H2) production and usage can be integrated into existing infrastructure to reduce carbon emissions and increase fuel supply security. In this work, we design and execute a technoeconomic analysis for a multifunctional District Energy System (DES) that produces and uses H2. We parametrically analyze levelized costs for H2, oxygen, and carbon dioxide abatement and capture to evaluate the viability of integrating H2 production, using Solid Oxide Electrolysis Cells, for a DES that could alternatively purchase H2 and install carbon capture utilization and storage (CCUS). We find that different project alternatives are distinctively sensitive to certain product prices, and therefore suitable for particular markets. Self-production alternatives with large H2 production do not require carbon pricing, so long as oxygen revenues are high. Conversely, when H2 is purchased, carbon prices in excess of $209/TonneCO2e are required for project viability. Projects with CCUS that purchase H2 depend on carbon-related revenues–even when hydrogen is free. When purchasing H2 in scenarios without carbon pricing, only projects using renewable-energy-based H2 and no CCUS implementation are viable for nonzero H2 prices (<$0.85/kgH2). Our work demonstrates that evaluating the levelized costs of all products in combination is necessary to assess the economic feasibility of multifunctional systems.
