“…Where, is a vector of deterministic input parameters and is a set of stochastic input parameters. Different methods of model reduction have been studied and some have found their way to the CCS field of research: Hanak and others have used Artificial Neural Network (ANN) models as surrogates for full physical calcium looping models, and have used these to perform integrated global uncertainty analysis of the economics of calcium looping systems [159,186]. Sun et al [187] used Polynomial Chaos Expansion (PCE) to produce surrogate models of physical models for CO2 storage well leakage and combined those with risk and cost analysis tools to retrieve stochastic integrated leakage risk and cost information.…”

Understanding the costs of carbon capture and storage (CCS) is essential to understand the role for and potential of CCS technology in addressing climate change, for guidance in research activities aiming to reduce the cost and improve the performance of promising new CCS technologies in different applications. In practice, however, there are many challenges in establishing reliable cost estimates for CCS technologies. To help identify and overcome these challenges, a group of experts from industry, government, academia and other organisations came together in 2011 to form the CCS Cost Network (which came under the aegis of IEAGHG in 2017 [1]). Following discussions at the first CCS Cost Network workshop [1], several members of the workshop steering committee formed a task force to focus on the basic structure of CCS cost estimates. That effort produced a White Paper entitled, "Toward a Common Method of Cost Estimation for CCS at Fossil Fuel Power Plants" [2]. This white paper aimed at overcoming identified pitfalls in CCS cost evaluations for fossil fuel power plants arising from the different methodologies used by various organisations. Towards this aim, the white paper established a common costing methodology and nomenclature, as well as guidelines for CCS cost reporting to improve the clarity and consistency of cost estimates for greenhouse gas mitigation measures. While that work laid the foundation for establishing a common costing methodology for CCS, several important cost issues still remained to be addressed. Building on that earlier work and the interest from additional organisations, the current white paper is an effort to draw up a complementary set of CCS costing guidelines in three complementary areas where further guidelines and better practices are needed, and where efforts are underway to address those topics. This effort is a collaboration among researchers at several industrial research institutes (Electric

“…This power-to-gas plant manages up to 40 MW e (i.e., 10% of the gross power of the CCPP). The overall efficiency of the energy storage is assumed constant at 60% (power to methane), accounting for polymer electrolyte membrane electrolysis (75% higher heating value, HHV) (Matute et al, 2019) and methanation (80% HHV) (Bailera et al, 2019a).…”

Massive penetration of renewable energy in the energy systems is required to comply with existing CO 2 regulations. Considering current power pools, large shares of renewable energy sources imply strong efficiency and economic penalties in fossil fuel power plants as they are mainly operated to regulate the system and constant shutdowns are expected. Under this framework, the integration of a combined cycle power plant (CCPP) with an energy storage technology such as power to gas (PtG) is proposed to virtually reduce its minimum complaint load through the diversion of instantaneous excess electricity. Power to gas produces hydrogen through water electrolysis, which is later combined with CO 2 to produce methane. The main novelty of this study relies in the improved flexibility and economics of combined cycles by means of using power to gas as a tool to reduce the minimum complaint load. The principal objective of the study is the quantification of cost reduction under different scenarios of shutdowns and conventional start-ups. The case study analyses a combined cycle of 400 MW e gross power with a minimum complaint load of 30% that can be virtually reduced to 20% by means of a 40-MW e power-togas plant. Eight scenarios are defined to compare the reference case of conventional operation under hot, warm, and cold start-ups with power-togas assisted operation. Additionally, PtG-assisted operation scenarios are analyzed with different loads (30-50-70%). These scenarios also include the consideration of a temporary peak of demand occurring in a period in which dispatch is below the minimum complaint load. Under this situation, the response time of conventional plants is very limited, while PtG-assisted CCPP can rapidly satisfy the peak. The techno-economic model quantifies the required fuel, gross and net power, and emissions as well as total costs and incomes under each scenario and net differential profit in an hourly basis. The analysis of the obtained results does not recommend the operation of the PtG-assisted CCPP at minimum complaint load for hot, warm, or cold start-ups. However, important marginal profits are achieved with the proposed system for part-loads operation over 50% for every sort of start-up, avoiding shutdowns and extending the capacity factor.

“…Syngas can also be produced through Power to Gas technology, which uses renewable electricity to obtain combustible gases by electrolysis [23]. The technology is ready for energy storage (Audi's PtG plant was qualified for participating in the German electricity balancing market) [24], although it needs subsidies to be profitable [25]. Its application to industries has been proved to be a more cost-effective solution [26,27].…”
