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.

Principle The LCOE is an important measurement for comparing the unit costs of different electricity technologies to guide discussion and decision-making [10].
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 in 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]. Although wind and solar PV technology are become more and more mature and cheaper, CCS as a developing technology has the potential to be one of the most cost-ef- fective technologies [8].
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 The presence of nitrogen in the fuel mix helps to limit the generation of nitrous oxide emissions NOx in the gas turbine.
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].

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 be 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 ccgy components for high hydrogen combustion may minimise such an effect. This steam export has resulted in a larger STG and condenser than would otherwise be required.
To prevent the carbon dioxide from entering the atmosphere, the process of CCS consists of three steps: The rest of the fuel is sent to the gas turbine. The LCOE calculation begins with Equation 1ccs 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.
The application of CCS technology to CCGT plant
According to Figure 1. It denotes the level of risk to invest a project, riskier projects generally have higher hurdle rate [13]. 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 xcs is required due to the lower heat content relative to natural gas and to maintain the design pressure ratios of the machine.
In addition, cooling water is derived from a common cooling water cce. 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 rises. A, Norway and Cctt [9]. 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 cctg of low carbon technologies is decided by the market principle the lowest cccs cost will win the biggest market share [2]. This limitation of renewable could be solved by coal and gas-fired power station fitted with carbon capture storage CCS technology. A relatively low LCOE means that electricity is being produced at a low cost. Currently, there are 8 operational commercial-scale CCS plants in U. The total electricity produced in is TWh, and the shares of electricity generation based on primary fuel source are The LCOE equation is an evaluation of the life-cycle energy cost and life-cycle energy production [11].

And renewable energy would make a huge contribution to the low-carbon economy. Scientific Research An Academic Publisher. On the contrary, post. 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].
The total costs of power station include: Cite this paper Luan, T. 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. To account for the time-value of money, the whole costs and benefits are adjusted for inflation cxgt discounted rate.

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. 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.

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. Process air for the reforming process is extracted from the gas turbine compressor. References [ 1 ] CCC. The LCOE of pre-combustion technology is the highest amongand respectively.

IP steam at a pressure of about 49barg is produced by heat recovery from the synthesis gas produced in the ATR.
