Transition of Steam Utility Systems to Solid Biomass-Fuelled Boilers and Biomethane-Fuelled Fuel Cells in the Wet Pet Food Processing Industry

This study highlights the CO2e - emission reduction potentials and related economic consequences for changing the steam generation from fossil to renewable. Two different utility concepts are developed, including a steam accumulator for load management. The first concept integrates a solid biomass-f...

Two different utility concepts are developed, including a steam accumulator for load management.

The comparison of the reduction to the total costs resulted in 0.05 – 0.11 €/kg CO2e - reduction per year for the biomass fuelled system and for the fuel cell in 0.69 – 1.14 €/kg CO2e - reduction per year.

The study shows that switching to renewable energy sources and implementing load management measures, emissions can be reduced at corresponding additional costs.https://www.cetjournal.it/index.php/cet/article/view/10607

description This study highlights the CO2e - emission reduction potentials and related economic consequences for changing the steam generation from fossil to renewable. Two different utility concepts are developed, including a steam accumulator for load management.

The second concept uses a biomethane-fuelled fuel cell for the base load and a natural gas boiler as a backup boiler. A detailed process analysis and dimensioning of the technology and the accumulator is the basis for a dynamic simulation. In the simulation the steam accumulator volume is varied. In addition, the electricity usage of the fuel cell is optimized in terms of costs or emissions.
