This limitation of renewable could be solved by coal and gas-fired power station fitted with carbon capture storage CCS technology.

6.3 Interfaces with the CCGT

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. Cite this paper Luan, T. 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.

The LCOE is an important measurement for comparing the unit costs of different electricity technologies to guide discussion and decision-making [10]. 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]. Moreover, oxyfuel combustion technology has the trend to be the cheapest CCS technology. 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.


Scientific Research An Academic Publisher. A, Norway and Algeria [9]. The total electricity produced in is TWh, and the shares of electricity generation based cds primary fuel source are 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: It denotes the level of risk to invest a project, riskier cccs generally have higher hurdle rate [13].

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.

And renewable energy would make a huge contribution to the low-carbon economy. 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.

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]. First, carbon dioxide will be separated and captured either by before the combustion process by pre-combustion ccgf, or after the combustion process by post-combustion capture or oxy-combustion capture [4].

The application of CCS technology to CCGT plant

The LCOE of project starting from to Process air for the reforming process is extracted from the gas turbine compressor. Fcgt steam at a pressure of about 49barg is produced by heat recovery from the synthesis gas produced in the ATR. EPE Most popular papers. The overall pressure ratio of the GT is therefore similar to that of the reference plant without need for nozzle modifications.

A relatively cce LCOE means that electricity is being produced at a low cost. The LCOE represents the present value of the unit cost of electricity over the lifetime of the powerstation. The LCOE equation is an evaluation of the life-cycle energy cost and life-cycle energy production [11].

And the rest of greenhouse gases need to be paid the carbon cost, so the increasing carbon price leads to the increase of LCOE. According to Figure 1. References [ 1 ] CCC. CCS will play a vital role in efforts to limit the global warming.

The application of CCS technology to CCGT plant

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. But, the CCS technology has much cvs 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.

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

The hydrogen fuel gas for the gas cccs is supplied at a molar ratio of about However, renewable energy is difficult to meet the increasing energy demand and keep lights on. There is a gap between the LCOE and the financial costs in real electricity market due to some ccgt uncertainties such as fuel and carbon price.
