Abstract Stabilization and reduction of the atmospheric carbon dioxide (CO 2) concentration will be one of the prime challenges for the energy sector in the upcoming decades. Carbon capture and storage (CCS) is widely seen as a possibility to continue fossil power generation while contributing to CO 2 abatement. In future energy systems with high shares of fluctuating renewable energy generation, nuclear power will become increasingly important for power generation. The development of natural gas power is considered as one of effective ways to reduce emissions and socio-economic costs as well. As a measure to establish a climate-friendly energy system, a power system research on coordinated development of nuclear and natural gas power would be considered. Therefore, future electrical power scenarios aimed at environmental and economic effects for China would considered a full mix of energy options. Based on the LEAP tool, this paper establishes a bottom-up model (LEAP-China-Power) to simulate different electric power planning policy scenarios that could be enacted from 2012 to 2050. In addition to a baseline scenario, we design CCS scenario and nuclear and Natural Gas Combined Cycle(N&N) scenario. The results indicate that N&N scenario is superior to CCS scenario. And China's future power planning recommendations are proposed. [ABSTRACT FROM AUTHOR]

In recent years, investment into carbon capture and storage (CCS) technologies has been seemingly sidelined to encourage larger renewable energy generation investment. High initial CCS costs have to compete with decreasing renewable costs and in some scenarios the role of CCS is completely overtaken by renewable energy. However, not recognising the value of a wider variety of low-carbon options in an energy system and committing to a single low-carbon technology can lead to a reduction in flexibility and further down the line even a lock out from successfully adapting the system to new advancements in smart technologies. On the path to a greener British energy system, gas power plants are considered as the transitional technology given the intermittent nature of most renewable generation. CCS can play a crucial role in mitigating the polluting effects of conventional generation. This paper employs real options analysis (ROA) to explore various cost and flexibility states, accounting for various penetrations of CCS and renewables working in cohesion. [ABSTRACT FROM AUTHOR]

Low-carbon energy systems are being proposed as portfolio of solutions to mitigate CO 2 emissions from the electricity-generating power sector. Stakeholder's perception on such technology plays a crucial role in its successful implementation. Not only the technological and economic aspects, but also the environmental and social aspects that surround these technologies should be considered in in determining which of these energy systems should be promoted, invested in, and subsidized. This decision problem should take into consideration the trade-offs due to several conflicting aspects involved in the prioritization. This paper thus proposes Fuzzy Analytic Network Process as a decision modeling tool in a group decision making environment to address the complexity of the decision structure and the uncertainty inherent in eliciting value judgments from stakeholders or experts. Fuzzy numbers are used to model the uncertainty, vagueness and incompleteness of information thus derived. The method then extends the fuzzy preference programming technique to derive the group priorities or weights from fuzzy pairwise comparative judgment matrices. A numerical example is presented to illustrate the proposed approach in prioritizing low carbon energy systems in the Philippines. [ABSTRACT FROM AUTHOR]

Representative carbon dioxide capture and storage (CCS) system of the post-combustion, no matter it employs adsorption, absorption or cryogenics separation technologies, commonly requires significant amounts of energy for the fundamental operation. Thus, energy consumption and related cost rise are primary challenges for the promotion of post-combustion technology. Solar thermal energy has already been widely used as an effective and clean energy source in industrial applications for drying, heating and even cooling since the last century. Various options of solar collector, such as flat plate type, evacuate tube type, and parabolic trough type, facilitate a comprehensive energy supply in different energy quality grades. In this paper, a technological framework for the energy efficiency in post-combustion CO2 capture is briefly presented for a connection between the energy demand of a CCS system and the energy supply of solar thermal engineering. The match performance between solar thermal utilization systems and CCS system is discussed in terms of energy form of the demand side (CCS), energy grades of supply sides (solar collector), and possible dynamic adjustment [ABSTRACT FROM AUTHOR]

As an end user of energy products, carbon dioxide capture and storage (CCS) system commonly requires a significant amount of energy to sustain a steady operation. As a renewable energy source, solar energy can supply plenty of thermal energy in different grades through various types of solar collector. Between the demand and supply sides, several technologies of solar thermal engineering can be applied as a bridge for an energy efficient design. In this paper, a technological framework for the energy efficiency in post-combustion CO 2 capture is further discussed as a second section of the two-part study. Based on existing research, several possible options of alternative energy supply to CCS system are analyzed, particularly for solar thermal energy. Moreover, some key design issues for the solar-assisted CCS system, such as integrated solar reactor with the regeneration component, are discussed as well. [ABSTRACT FROM AUTHOR]
