Project description

AGRO-SOFC aims to reduce the energy consumption by at least 10% through load shift and sector coupling using solid oxide fuel cells (SOFC) and intelligent control strategies in greenhouses.

As part of the project, a highly efficient and ecological system is being developed and demonstrated, which connects the agricultural industry as a “need owner” with SOFC technology.

The SOFC system enables the generation of electricity power with an electrical efficiency of more than 65%, which reduces energy consumption and ensures process reliability. The waste heat from the SOFC is used to heat the greenhouse. Such a system can include run on renewable hydrogen and biogas (common in the agricultural industry). The load shift and the sector coupling must not have a negative impact on the operation or the process if these effects cannot be compensated. The intelligent operating strategy of the SOFC should enable energy-efficient and low-degradation operation. Here, the optimal operating conditions are first determined in the laboratory so that these operating properties can also be achieved later in the pilot system with appropriate control devices and with the help of machine learning.

The end consumers also benefit from the reduction in energy demand since the energy demand has a significant impact on the production costs of the greenhouse products.
