Solar-hydrogen conversion in Croatian solar house

Croatian Solar House (CSK) actually represents a laboratory, where, among other things, solar hydrogen energy conversion will be examined and developed. Therefore, this paper shows photovoltaic (PV) systems that are sized for fulfilling all the consumers’ electric energy needs and at the same time deliver their excess energy to the electric grid on which that system is connected. PV systems consist of four PV generators which are connected through the power conditioning unit and DC/AC inverter on a mutual assembly part. For energy storage a hydrogen system will be used which consists of an electrolyser, fuel cell, metal-hydrid storage and pipelines. The storage capacity is determined by balancing the energy so that it covers daily and seasonal energy needs as far as possible, and makes CSK energetically independent. This paper intends to pave the way towards a mathematical model for optimal sizing of PV generator and hydrogen storage, which satisfies consumers’ needs for electric energy.
