A relatively low LCOE means that electricity is being produced at a low cost. However, renewable energy is difficult to meet the increasing energy demand and keep lights on.

On the contrary, post- Figure 1. 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.

It denotes the level of risk to invest a project, riskier projects generally have higher hurdle rate [13]. According to Figure 1.

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].

In addition, cooling water is derived from a common cooling water system.

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

However, since the configuration of Scenario 5 is such that the GT compressor is sized to also cce 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 LCOE of project starting from to The LCOE represents the present value of the unit cost of electricity over the lifetime of the powerstation. A, Norway and Algeria [9]. The rest of the fuel is sent to the gas turbine.

Process air for the reforming process is ccgt from the gas turbine compressor. 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 of components for high hydrogen combustion may minimise such an effect.

On the contrary, post. Moreover, oxyfuel combustion technology has the trend to be the cheapest CCS technology. Energy and Power Engineering9 The estimate of fuel price from to is on the basis of DECC [19] fossil fuel price assumptions report.

Currently, there are 8 operational commercial-scale CCS plants in U. The total costs of power station include: Typically when firing hydrogen in a cct 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.

This limitation of renewable could be solved by coal and gas-fired power station fitted with carbon capture storage CCS technology. 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. 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 This steam export has resulted in a larger STG and condenser than would otherwise be required.

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].

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 application of CCS technology to CCGT plant

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. The LCOE of pre-combustion technology is the highest amongand respectively. 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.
