Techno-economic assessment of providing control energy reserves with a biogas plant

Ervin Saracevic, David Woess, Franz Theuretzbacher, Anton Friedl, Angela Miltner

Frontiers of Chemical Science and Engineering 2018, Volume 12, Issue 4,   Pages 763-771 doi: 10.1007/s11705-018-1776-x

Abstract:

Grid stability is being challenged by the increasing integration of power plants with volatile power generation into the energy system. Power supply fluctuations must be compensated by energy system flexibility. The storability of the energy carrier enables biogas plants to generate power flexibly. In this study, the technical and economic effects of providing positive secondary control energy reserves with an Austrian biogas plant were assessed. The plant’s main focus lies in biomethane production with the option of heat and power generation through combined heat and power (CHP) units. A detailed simulation model of the investigated biogas plant was developed, which is presented in this work. Ex-post simulations of one year of flexible plant operation were conducted with this model. The findings show that the installed biogas storage capacity is sufficient to provide control energy reserves while simultaneously producing biomethane. Profitability of providing control energy reserves largely depends on the prices at the control energy market and on CHP unit start-up costs. A cost efficiency analysis demonstrated that investing in a hot water tank with a volume of 5 m3 for short-term heat storage turned out to be economically viable.

Explanation of Essence of Engineering———On Relationship between Engineering and Science and Techno logy

Huang Zhengrong

Strategic Study of CAE 2007, Volume 9, Issue 11,   Pages 115-119

Abstract:

Engineering is a construction activity and process to reform the nature under certain restriction (including decision. ,design, construction and evaluation), following necessary procedure, design documents,  regulations, rules and standards to integrate basic production elements and resource with specific related engineering science, engineering technology and management principles, its final result is an engineering body with predetermined functions. The essence of engineering is the sum of mass activities to utilize and reform the nature. The basic characters of engineering are integration, mass involved, dynamic and with agreement. The close relationship between engineering and science and technology expresses the incorporation of engineering and science and technology, as well as confluence,  unity and interaction of engineering with science and technology.

Techno-economic assessment of pulverized coal boilers and IGCC power plants with CO 2 capture

Frontiers of Chemical Science and Engineering 2010, Volume 4, Issue 2,   Pages 196-206 doi: 10.1007/s11705-009-0237-y

Abstract: The current studies on power plant technologies suggest that Integrated Gasification Combined Cycle (IGCC) systems are an effective and economic CO capture technology pathway. In addition, the system in conventional configuration has the advantage of being more “CO capture ready” than other technologies. Pulverized coal boilers (PC) have, however, proven high technical performance attributes and are economically often most practical technologies. To highlight the pros and cons of both technologies in connection with an integrated CO capture, a comparative analysis of ultrasupercritical PC and IGCC is carried out in this paper. The technical design, the mass and energy balance and the system optimizations are implemented by using the ECLIPSE chemical plant simulation software package. Built upon these technologies, the COcapture facilities are incorporated within the system. The most appropriate CO capture systems for the PC system selected for this work are the oxy-fuel system and the postcombustion scheme using Monoethanolamine solvent scrubber column (MEA). The IGCC systems are designed in two configurations: Water gas shift reactor and Selexol-based separation. Both options generate CO-rich and hydrogen rich-gas streams. Following the comparative analysis of the technical performance attributes of the above cycles, the economic assessment is carried out using the economic toolbox of ECLIPSE is seamlessly connected to the results of the mass and energy balance as well as the utility usages. The total cost assessment is implemented according to the step-count exponential costing method using the dominant factors and/or a combination of parameters. Subsequently, based on a set of assumptions, the net present value estimation is implemented to calculate the breakeven electricity selling prices and the CO avoidance cost.
