Overview

Fuel cell module for heat and power generation

140 l buffer cylinder

Wall mounted gas condensing boiler Logamax plus GBH172 T75S for central heating backup and DHW convenience

75 l stratification cylinder

Implementation

SOFC

Buffer

Boiler

DHW

Solid Oxide Fuel Cell Continuous power production

by the fuel cell. Produced heat is stored in the buffer tank.

During heat demand, energy is used out of the buffer tank

Sufficient energy (tank loaded): Boiler is out

Insufficient energy: Boiler starts

Comparison with Austria – Upfront subsidy programsBAFA program: Technology open federal subsidy program to push efficient and

renewable heating systems (e.g. solar thermal, heat pumps, mCHP, …) in Germany.

BAFA mCHP subsidy:Scope: mCHP up to 20 kWel

Only refurbishment applications(residential and commercial use)

Criteria: Min. total efficiency η ≥ 0.85, offer of service contract, combination with buffer tank

Subsidy: Basic subsidy (1 900 EUR)+ additional heat bonus (25% of basic subsidy)+ power bonus (60% of basic subsidy) for efficient units Subsidy of 3 515 EUR for BOSCH system

Existing mCHP subsidy program for fuel cells in commercial applications



11

Comparison with Austria – Upfront subsidy programsKfW program 433 (TEP subsidy program for fuel cells) was officially introduced in 08/2016

Budget: 500 Mio EUR over 8 years (starting end of 2016)Target: To reach volumes of 60-70 000 fuel cell units per yearScope: Fuel cell with 0.25 kWel to 5 kWel,

1 and 2 family houses (new build and refurbishment), no commercial application

Criteria: Min. efficiency total η ≥ 0.82; ηel ≥ 0.3210 years full service contractEvaluation via independent energy expert

Subsidy: Basic subsidy 5 700 EUR Add. Support 3 150 EUR (450 EUR per 100 Wel) Subsidy of 8 850 EUR for 700 W BOSCH system

New fuel cell subsidy program for residential applications will push the fuel cell market



12

Comparison with Austria – annual subsidy

Additional annual payment subsidy for generated and exported power into the grid

KWK law (CHP subsidy program) was updated in 01/2016.Subsidy program gives financial support via annual payments for generated and exported power to the grid of CHP systems in general.

Criteria: max. 50 kWelmax. operation time of 60 000 h

Subsidy: Self-consumption: 4.0 Cent/kWhFeed in tariff: 8.0 Cent/kWh

For electricity(incl. self consumption) 1337 € 517 €

Benefits / savingsμCHP bonus for self-consumption (4 Cent/kWh) - 118 €
