Development of a measuring concept of a demonstration plant for the electrolytic co-production of hydrogen, oxygen and heat with renewable electricity

Abstract

The purpose of this work is to propose a monitoring system to evaluate the performance of a test plant for the co-production of hydrogen, oxygen and heat from renewable energy sources. In order to evaluate the performance of this new system, a suitable monitoring system should be developed together with the corresponding equations to involve the parameters measured. For this, the parameters necessary to describe the system will be selected and all necessary sensors together with the measuring principles will be described and placed within the plant scheme. The equations necessary to evaluate the plant performance, that is, mass balances, energy efficiency, and economical performance are included in the following section. Also considered, is the frequency of measurement within the different operation phases of the core element of this plant, the electrolyzer. The monitoring system was proposed with general considerations since the plant is still to be constructed and the details of it are not available (in order to select the exact type of sensors). It provides therefore, the basis for its further development.
