CCS technology could capture up to 90% of carbon dioxide from emissions and This paper presents the levelised cost of electricity of CCGT with CCS and. Prior to delivery to the CCGT power block, the fuel gas is heated to 78°C as an efficiency measure, using waste heat in the form of low pressure steam generated. Tom will be providing an overview of Combined Cycle Gas Turbine (CCGT) is part of the team engaged in developing the Peterhead CCS Project – one of two .

cxgt The acceptability of low carbon technologies is decided by the market principle the lowest generation cost will win the biggest market share [2]. And renewable energy would make a huge contribution to the low-carbon economy.

The application of CCS technology to CCGT plant

In addition, cooling water is derived from a common cooling water system. International Energy Agency, Par-is. This limitation of renewable could be solved by coal and gas-fired power station fitted with carbon capture storage CCS technology. The required concentration of N 2 is achieved by varying the amount of process air sent to the ATR. The total costs of power station include:. The overall pressure ratio of the GT is therefore similar to that of the reference plant without need for nozzle modifications.

To account for the time-value of money, the whole costs and benefits are adjusted for inflation and discounted rate. The LCOE of project starting from to But, the CCS technology has much potential to reduce its LCOE, such as investing in large CO 2 storage cce with shared ccbt to decrease the operation cost; re-use of existing oil and gas infrastructure to reduce the construction cost; developing a subsidiary supply business to increase the revenue of power plant.

On the contrary, post- Figure 1. The total costs of power station include: The LCOE represents the present value of the unit cost of electricity over the ccbt of the powerstation. First, carbon dioxide will be separated and captured either by before the combustion process by pre-combustion capture, or after the combustion process by post-combustion capture or oxy-combustion capture [4].


CCS will play a vital role in efforts to limit the global warming. The paper is not in the journal. Process air for the reforming process is extracted from the gas turbine compressor. Energy and Power Engineering9 Arup and Leigh [Fisher [16] [17] provide cost and technical assumptions for the renewable technologies and non-renewable technologies individually; NERA Economic Consulting [18] provide a report on hurdle rates ccgy projects starting development from References [ 1 ] CCC.

Delivering Our Low Carbon Future. There is a gap between the LCOE and the financial costs in real electricity market due to some specific uncertainties such as fuel and carbon price.

The LCOE is an important measurement for comparing the unit costs of different electricity technologies to guide discussion and decision-making [10].

On the contrary, post. According to Figure 1. EPE Most popular papers. To evaluate the total cost of electricity, the streams of costs are converted to a net present value using the time value of money by discounted vcs flow model.

However, since the configuration of Scenario 5 is such that the GT compressor is sized to also supply compressed air for use in the reforming process, the increase ccgf volumetric flow of fuel into the GT is offset by the equal amount of additional air extracted for the process.

According to the International Energy Agency, more than CCS projects must be set up and be running by worldwide [6].

The LCOE cfgt begins with Equation 1expressing the equality between the present value of the sum of revenues on the left-hand side and the present value of the sum of costs on the right-hand side.


LCOE of Wind and solar PV technologies is decreasing due to the reduction of construction cost and cs of average load factor. The LCOE equation is an evaluation of the life-cycle energy cost and life-cycle energy production [11]. Ccgy steam at a pressure of about 49barg is produced by heat recovery from the synthesis gas produced in the ATR. The waste heat IP intermediate pressure steam generator is a major element of the reforming process heat recovery system.

A, Norway and Algeria [9]. The hydrogen fuel gas for the gas turbine is supplied at a molar ccw of about Currently, there are 8 operational commercial-scale CCS plants in U. In the UK electricity system, gas and coal- fired power station with CCS is an unavoidable option in order to meet the increasing energy demand and keep lights on whilst minimizing the environmental damage [7].

Typically when firing hydrogen in a gas turbine, the turbine nozzle area must be increased from that of the reference plant, to accommodate the increased volumetric flowrate of fuel which is required due to the lower heat content relative to natural gas and to maintain the design pressure ratios of the machine. Discounted rate, also known as the hurdle rate, is the minimum Internal Rate of Return IRR that a company expects to earn when investing in a project.

It denotes the level of risk to invest a project, riskier projects generally have higher hurdle rate [13]. In general, every reasonable effort has been made to maximise use of the waste heat which is generated by the process and to thereby optimise the net efficiency of the overall plant.

A relatively low LCOE means that electricity is being produced at a low cost. Cite this paper Luan, T.
