Micro CHP
MTT's micro CHP system: the EnerTwin

Based on the MTT 3 kW micro turbine design, a 3 kW electrical / 15 kW thermal micro CHP system is being developed to replace heating boilers for small business and households. Major focus is given to low cost price, reliability, noise reduction and low maintenance.

For the end users the overall efficiency (accounting for the higher value of electric power) is substantially higher than current condensing boilers. The payback time of the system is between 2 and 5 years, depending on the operating profile and outside temperatures. It can reduce the energy bill by 20 - 25%. CO2 savings of up to 6 tons per year are possible for each installed system.

For domestic appliances, as a rule of thumb, a 1 kWe micro CHP system leads to an annual energy bill saving of €300 - €350; for the 3 kWe MTT’s micro CHP this means ± € 1,000 cost reduction per year. This allows for a pay-back time between 2 and 5 years (independent of subsidies).

Savings for SME appliance of the MTT micro CHP system are considerably higher, as the annual running hours are normally higher.

The MTT micro turbines have significant cost advantages over alternative CHP solutions with inherent complexity such as reciprocating engines and fuel cells. This offers economically feasible micro CHP solutions that do not depend on government subsidies for successful market entry.

A prototype of MTT’s micro CHP system was built and is being extensively tested. As from mid 2013, the EnerTwin is in field trials which are expected to last until the end of 2014. Commercial launch is foreseen from end 2014 / early 2015.
