Techno-economic analysis

A novel BIO-CCHP trigeneration system includes biomass gasification, a Solid Oxide Fuel Cell (SOFC) stack and a cooling machine. Process flow chart of the system is presented in the diagram below:

The techno-economic calculator visualizes the economic perfomance of the proposed system. The output contains a net present value, payback period and discounted cumulative chart flow derived from the user's input values.

Economic parameters

It is assumed that 60% CAPEX is invested in year 0 and 40% CAPEX in year one. No revenue and other costs (OPEX and feedstock cost) for year zero, 50% percent of revenue and costs in year one.

It is assumed that all generated electricity is sold, and the produced heat and cold are sold up to the demand specified below:

Raw material (biomass feedstock) price: €/MWh

Electricity price: €/MWh

Heat demand (market potential) MWh/year

Cold demand (market potential) MWh/year

Heat price: €/MWh

Cold price: €/MWh

1% inflation is assumed for all prices.
