Eco-technology spin-off in Brussels: higher return from combined heat and power (CHP) systems 

After delivering electricity, power plants usually dispose of a considerable amount of residual heat. The combined heat and power (CHP) system uses this extra energy and by offering this combination of heat and power, a CHP has a return of over 80%.

The most widely spread CHP technologies are internal combustion engines (ICE) and (micro) gas turbines (MGT). All CHP installations deliver a fixed ratio between produced heat and power, which does not necessarily follow the demand on-site. To solve this problem, a new technology has been conceived for MGT CHP installations.

The idea for this technology was first conceived as a sidetrack of Frank Delattin’s doctoral thesis (2010). The new technique can adapt the delivered heat and power as a function of (changing) demand and can augment the electrical efficiency of the engine when no heat is required at all.

The core idea of the project is to create a spin-off company that can commercialize the required components to make flexible power/heat generation possible for microturbine CHP units. The flexibility in power/heat produced allows the installation to increase its yearly running hours, drastically lowering the payback time on the investment.

This Spin-Off In Brussels project, funded by Innoviris is part of the valorization strategy of the MECH group, which is also granted the title ‘grower’ by the Industrial Research Fund (IOF).
