Techno-economical studies about performance of industrial scale CLC power plant
In this study the primary focus is on economic evaluations for industrial scale greenfield chemical-looping-combustion (CLC) power plant. In the tool it is possible to analyse the operation with different input parameters and make comparison to both oxy-fired circulating fluidised bed (CFB) plant and normal air-fired CFB plant using coal as a fuel. The whole CCS chain, including CO2 capture, processing, transport and storage, is included. As there is no storage capacity in Finland the captured CO2 has to be transported and stored abroad.
In the toolkit, the profitability of each case can be analysed according to different market situations by adjusting plants operation and the most significant input values. In addition to plant and case specific technical inputs, the economic parameters can be varied as well as CCS related costs, for example required investment, transportation costs, prices for oxygen carrier materials etc.
Our customers tell us that collaborating with VTT adds value in a number of ways. It brings fresh thinking to the table, offers proven technologies that can be tailored to their specific needs, and accelerates the development and implementation process.
How we work
Working with VTT is different. Instead of developing everything internally or working with companies pushing proprietary solutions, we function as an extended part of your team. With VTT, you are tapping into platform chemical sector research and development that is both deep and broad.
