Electricity production costs and specific CO2 emission for CSP-CFB hybrid power plant


In this study electricity production cost analysis tool for CSP-CFB hybrid power plant with different CO2 reductions levels is presented. The case studies include different mixtures of coal and biomass co-fired in a circulating fluidised bed (CFB) boiler integrated with concentrated solar power (CSP) plants. Results include for example the break-even price for available sustainable biomass, which would turn investment on CSP and integration feasible over the case, where greater amount of biomass is purchased.

The properties of modelled CFB boiler are based on existing 400 MWe plant resulting very large solar field. The considered fuel mixes include the required biomass shares to reach emission performance standards (EPS) levels of CO2 in the both dimensioning cases and with different operation schemes of the plants. The chosen approach was to use equal annual electricity production for all the cases around the year.

​Fresh thinking

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.
