日本語

本論文は、電化による脱炭素化対策の効果評価において、電力排出係数の経年変化と国別差異がCO2削減量の過大・過小評価を引き起こす可能性を指摘する。欧州の産業部門を対象に、高温ヒートポンプを統合したCCHPシステムを事例とし、2050年までの排出係数シナリオ下で定常・年間運転シミュレーションを実施。従来システムとの比較により、長期的な炭素削減予測の偏りを定量的に示した。

English

This paper examines how the evolution and country-specific differences of electricity emission factors can lead to over- or underestimation of CO2 savings from electrification-based decarbonization measures. Using a high-temperature heat pump integrated into a CCHP plant as a case study, steady-state and annual simulations under various European emission factor scenarios until 2050 reveal biases in long-term carbon reduction projections compared to conventional systems.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本では、SSBJ開示や省エネ法改正に伴い、電化による排出削減効果の算定が重要となる。本論文の手法は、日本の電力排出係数の将来見通しを考慮した脱炭素投資の有効性評価に示唆を与え、中長期の排出削減計画の精度向上に寄与する。

In the global GX context

Globally, as companies align with ISSB and CSRD, accurate accounting of emission reductions from electrification is critical. This paper provides a methodological framework to avoid biases in long-term carbon savings projections, relevant for transition planning and science-based targets.

📄 Abstract(原文)

The evaluation of the effectiveness and sustainability of decarbonization measures, especially but not only through electrification, is not trivial. Combustion technologies improve by small amounts year to year and as the emission factors of fuels can be considered constant across European countries; however, the emission factors of electricity generation are not uniform among countries and do not share a common trend in their evolution over time. These two aspects, the different evolution trends of electricity emission factors and the non-uniformity of these factors among countries, can lead to unexpected results: under/overestimation of carbon savings and sustainability in the long-term forecast in the massive technologic transition in both the civil and industrial sectors. This paper, using trend observations and the Myopic model, highlights possible biases in the long-term projection of CO2 emissions savings in the industrial sector. This study focuses on a comprehensive investigation of the integration of a high-temperature heat pump into a combined cooling, heating, and power plant. A detailed assessment of the system’s energy performance is conducted through steady-state simulations under both fixed boundary conditions and annual operational scenarios, addressing building heating, cooling, and electrical requirements across varying electricity emission factors for different European countries and evolution trends until 2050, with the results compared with conventional energy production systems.
