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 .

However, renewable energy is difficult to meet the increasing energy demand and keep lights on. A de-rating of the standard GT inlet temperature that has been modelled may ccgr required in practice for H 2 firing due to the greater heat transfer to the blades, and this would result in a slight reduction in efficiency of the overall plant; however, the development of components for high hydrogen combustion may minimise such an effect. Some excess steam is also used for heat exchange within the reforming process.

The LCOE calculation 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. Please enable JavaScript to view the comments powered by Disqus. This limitation of renewable could be solved by coal and gas-fired power station ccgy with carbon capture storage CCS technology.

The waste heat IP intermediate pressure steam generator is a major element of the reforming process heat recovery system. EPE Most popular papers.

To account for the time-value of money, the whole costs and benefits are adjusted for inflation and discounted rate. However, since the configuration fcs Scenario 5 is such that the GT compressor is sized to also supply compressed air for use in the reforming process, the increase in volumetric flow of fuel into the GT is offset by the equal amount of additional air extracted for the process.

The total costs of power station include:.

The application of CCS technology to CCGT plant

According to Figure 1. 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.

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 cash flow model. Delivering Our Low Carbon Future.


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 for projects starting development from Cite this paper Luan, T.

But, the CCS technology has much potential to reduce its LCOE, such as investing in large CO 2 storage clusters with shared pipelines 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.

Skip to main content. According to the International Energy Agency, more than CCS projects must be set up and be running by worldwide [6]. And the rest of greenhouse gases need to be paid the carbon cost, so the increasing carbon price leads to the increase of LCOE.

Energy and Power Engineering9 Currently, there are 8 operational commercial-scale CCS plants in U. To prevent the carbon dioxide from entering the atmosphere, the process of CCS consists of three steps: Typically when firing hydrogen in a gas turbine, the ccgtt 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.

6.3 Interfaces with the CCGT

If the LCOE of CCGT with CCS could be reduced to an appropriate price level, the UK government could use CCS technology to maintain secure and low carbon electricity as more intermittent renewables and inflexible nuclear come onto the grid, and does not worry about the suddenly increased household electricity bills. A relatively low LCOE means that electricity is being produced at a low cost.

The LCOE of pre-combustion technology is the highest amongand respectively. The LCOE of project starting from to Scientific Research An Academic Publisher. 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 cc whilst minimizing the environmental damage [7].

The total costs of power station include: 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. The hydrogen fuel gas for the gas turbine is supplied at a molar ratio of about The total electricity produced in is TWh, and the shares of electricity generation based on primary fuel source are In addition, cooling water is derived from a common cooling water system. The Ccd is an important measurement for comparing the unit costs of different electricity technologies to guide discussion and decision-making [10].


The acceptability of low carbon technologies is decided by the market principle the lowest generation cost will win the biggest market share [2]. To achieve the greenhouse gases reduction target, CCS technology will play as an important role to a low-carbon future, which allows continued use of fossil fuels whilst limiting global temperature cfs.

The LCOE equation is an evaluation of the life-cycle energy cost and life-cycle energy production [11]. The required concentration of N 2 is achieved by varying the amount of cgt air sent to the ATR. IP steam at a pressure of about 49barg is produced by heat recovery from the synthesis gas produced in the ATR. Principle The LCOE is an important measurement for comparing the unit ccz of different electricity technologies to guide discussion and decision-making [10]. On the contrary, post- Figure 1.

This steam export has resulted in a larger STG and condenser than would otherwise be required.

The paper is not in the journal. International Energy Agency, Par-is. Process air for the reforming process is extracted from the gas turbine compressor. Conflicts of Interest The authors declare no conflicts of interest. The estimate of fuel price from to is on the basis of DECC [19] fossil fuel price assumptions report. The boiler feed water supplied to the heat recovery system is obtained from the CCGT a larger boiler feed water system has been allowed for.

Moreover, oxyfuel combustion technology has the trend to be the cheapest CCS technology. 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 vcgt net efficiency of the overall plant.

It denotes the level of risk to invest a project, riskier projects generally have higher hurdle rate [13]. CCS will play a vcgt role in efforts to limit the global warming.
