Abstract

The utilization of power-to-X (PtX) technologies as a substitute for fossil fuels is a key instrument in defossilizing the global economy, potentially making a significant contribution to sustainability efforts. This must be ensured or at least supported by legal measures to maximize the full sustainability potential. Thus, in recent years, regulations have been created to ensure sustainable PtX production on the one hand and to promote the use of PtX products on the other. The diversity and complexity of these regulations, differing in their scope of application, the applied instruments, and the respective sustainability requirements, among other things, create potential hurdles for PtX projects and complicate determining the respective influence on technical, economic, and environmental aspects. This review aims to summarize, classify, and assess current sustainability regulations and to evaluate the impact on potential PtX projects. The paper underscores the significance of the EU Renewable Energy Directive (REDIII) as the blueprint or reference for the legal regulations within the EU member states as well as the respective certification schemes and incentive and support schemes. The impact of sustainability criteria (power supply and GHG threshold) on PtX projects is analyzed and discussed, highlighting the importance of the electricity provision concept and sustainable carbon supply.

PtX项目的可持续性法规：范围和影响分析

利用电力到x （PtX）技术作为化石燃料的替代品，是全球经济去化石化的关键手段，可能对可持续发展的努力做出重大贡献。这一点必须得到保证，或至少得到法律措施的支持，以最大限度地发挥充分的可持续性潜力。因此，近年来，制定了法规，一方面确保可持续的PtX生产，另一方面促进PtX产品的使用。这些法规的多样性和复杂性，在适用范围、应用工具和各自的可持续性要求等方面有所不同，给PtX项目造成了潜在的障碍，并使确定各自对技术、经济和环境方面的影响变得更加复杂。本综述旨在总结、分类和评估当前的可持续性法规，并评估对潜在PtX项目的影响。本文强调了欧盟可再生能源指令（REDIII）作为欧盟成员国法律法规以及各自认证计划和激励支持计划的蓝图或参考的意义。分析和讨论了可持续性标准（电力供应和温室气体阈值）对PtX项目的影响，强调了电力供应概念和可持续碳供应的重要性。
