• Hot exhaust of SOFC is suited for warming of hot water
• High heat pump efficiency for space heating
Case: building integration with high efficiency

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

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

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
