We are jointly developing a fuel cell calciner as part of the collaborative BEN (Balanced Energy Networks) project in London. The BEN consortium is delivering both a physical and digital network to integrate systems that will enable the balancing of heating, cooling, electricity and carbon to minimise costs – and help combat global warming.


At a glance

We are working in collaboration with carbon-negative technology business Origen Power as part of a wider project which will see a new Balanced Energy Network (BEN) built on the London South Bank University campus in Southwark.

We are aiming to utilise the waste heat and chemical energy from a solid oxide fuel cell (SOFC) in an innovative calciner. This will enable the production of a pure stream of CO2 ready for sequestration. The spent natural sorbent will be used to capture CO2 from the atmosphere and so provide negative CO2 overall emissions, while generating electricity.

This technology will contribute in keeping the concentration of CO2 in the atmosphere as low as possible, in order to combat global warming.

Further information

This programme was developed to assess the impact of the key economic input parameters on the feasibility of the novel process for simultaneous power generation and CO2 capture from the air.

In the current version, the thermodynamic data is taken from the process model developed in Aspen Plus®. The user can select three different materials (limestone, dolomite, or magnesite) that differ in the chemical composition and price. The effect of the following key economic input parameters on the process economic performance can be studied:

  • Carbon tax [£/tonne]
  • Cost of CO2 transport and storage [£/tonne]
  • Specific cost of fuel [£/GJ]
  • Capacity factor [%]
  • Discount rate [%]
  • Project lifetime [year]

The key parameters indicating process economic performance are:

  • Maximum levelised cost of electricity [£/MWh]
  • Maximum levelised cost of CO2 capture from air [£/tonneCO2]
