摘要

系统建模工作表明,碳捕集是一项关键技术,可使能源密集型工业以具有成本效益的方式减少难以消减的排放。捕获的二氧化碳既可以被利用(CCU),也可以通过碳捕获与封存(CCS)储存起来。本文探讨了欧洲碳定价机制(ETS I & ETS II)对 CCS 和 CCU 投资公平竞争的影响。我们的贡献体现在三个方面。首先,我们建立了一个均衡模型,使我们能够模拟不同监管条件下的市场结果。通过对燃料生产链的数值案例研究,该模型证实了当前的排放交易计划法规会对 CCU 的吸收产生不利影响。特别是在第二类排放交易计划价格为零或较低的情况下,CCS会产生锁定效应,从而可能延长传统炼油厂的活动。其次,我们提出了一种替代方法,以更好地将 CCUS 纳入欧盟排放交易计划。结果表明,无论碳价格是否存在差异,这种方法都能保持 CCU 和 CCS 之间的公平竞争。这使得在福利和减排方面更接近帕累托最优结果。第三,我们提出了一种分析方法,从理论角度表达了 CCUS 的权衡。这为欧盟排放交易计划如何影响 CCUS 的盈利能力和可能性提供了概括性的具体见解。我们的研究结果有助于政策制定者更好地理解 ETS 法规对行业脱碳努力的影响。

Implications of the EU ETS on the level-playing field between carbon capture storage & utilisation

System modelling efforts have shown that carbon capture is a key technology to enable a cost-effective reduction of hard-to-abate emissions in energy-intensive industries. The CO2 that is captured can either be utilised (CCU), or stored with carbon capture and storage (CCS). This paper examines the implications of both European carbon pricing mechanisms (ETS I & ETS II) on the level-playing field between CCS and CCU investments. Our contribution is threefold. First, we develop an equilibrium model that enables us to mimic market outcomes under different regulatory conditions. With a numerical case study applied to a fuel production chain, the model confirms that the current ETS regulation can have an adverse effect on CCU uptake. Especially with zero or low ETS II prices a lock-in effect can occur on CCS, potentially prolonging conventional refinery activities. Second, we propose an alternative approach to better integrate CCUS into the EU ETS. Results show that this approach maintains the level-playing field between CCU and CCS, regardless of any carbon price differentials. That results in a closer to Pareto optimal outcome in terms of welfare and emission abatement. Third, we present an analytic analysis to express the CCUS trade-off from a theoretical point of view. This provides generalised and concrete insights into how EU ETS influences the profitability and likelihood of CCUS. Our results help policymakers to gain a better understanding of the impact of ETS regulations on decarbonisation efforts in the industry.

期刊介绍: The International Journal of Greenhouse Gas Control is a peer reviewed journal focusing on scientific and engineering developments in greenhouse gas control through capture and storage at large stationary emitters in the power sector and in other major resource, manufacturing and production industries. The Journal covers all greenhouse gas emissions within the power and industrial sectors, and comprises both technical and non-technical related literature in one volume. Original research, review and comments papers are included.
