C50 combined with a heat pump

- Annual variability of heating and cooling demands balance each other; over 6000h utilization/ year for the heat pump

- Heat pump, ventilation and building automation form near constant base load best suited for SOFC system, variable load can be covered from grid

- In case of a grid failure, critical loads may be served by appropriately sized SOFC with Convion’s proprietary load following technology

• By combining a locally installed SOFC CHP system with

• CO2 emissios from heating may be reduced to 89 kg CO2/MWh

• Further reduction of emissions may be achieved by placing the SOFC installation into a building, thus utilizing lost low grade heat

• As a reference, CO2 emissions of independent heat generation for district heating in Finland are, on average, 226kg CO2/MWh*

Reduction of CO2 emissions is 60% with Convion products (*Source: Motiva)

Efficient, building integrated energy supply


• Reliability and independence of on-site power

generation facilitate safe and resilient operations

• Increased dependability increase customer value

• C50 units are capable of grid independent operation

• Maintenance interval is longer and reliability higher

compared with combustion engines

• C50 products be arranged in a parallel without sacrificing

efficiency

• Parallel units may be maintained independently

Increased dependability


ASSUMPTIONS:

- Grid unavailability per year is

1 hour

- Critical loads can be powered

by N parallel SOFC units with

one redundant module

- SOFC unavailability due to

scheduled and reactive

maintenance is independent

of state of power grid or

state of other SOFC units

• Since cost as €/MWh is higher with new energy technologies the other attributes may compensate the higher investment costs

• Fuel cells can increase customer value by providing higher energy efficiency, better power security and power independence

Case; power security has a significant value

Added value from fuel cells


© CONVION Global Fuel Cell Market

Global FC deliveries have grown annually close to 40% since 2006. Over 50% growth (in delivered MW) for 2012

In stationary SOFC started to replace PEMFC in residential applications. In larger stationary applications SOFC has fastest growth

SOFC seen as future winner due to better cost potential.

FC market potential and expectations are high
