On May 17, 2018, the National Center for Research and Development announced the initiation of a new procedure within the Hydrogen Storage Program. The objective was to develop a Hydrogen Storage System for use with fuel cells and its demonstration in a Mobile Facility. This is to create an alternative to the use of fossil fuels and create a field for competition in creating solutions in the field of access to “clean” energy. The National Center for Research and Development is responsible for the development of assumptions, regulations and implementation. The analysis presents the main assumptions of the program is correlated to the current legal situation related to the financing of Research and Development. An in-depth study concerns the ways of using innovative partnership and its placement in the system of European Union legal acts. The idea of the pre-commercial procurement procedure (Pre-Commercial Procurement), which was developed to support the implementation of prototypes of solutions – resulting from research and development – with a high potential for possible commercialization, was described in details. This procedure is characterized by ensuring the financing of a product or service at an early stage of development. Although this creates the risk of failure of the project, it stimulates technological development.
The paper describes factors influencing the development of electricity storage technologies. The results of the energy analysis of the electric energy storage system in the form of hydrogen are presented. The analyzed system consists of an electrolyzer, a hydrogen container, a compressor, and a PEMFC fuel cell with an ion-exchange polymer membrane. The power curves of an electrolyzer and a fuel cell were determined. The analysis took the own needs of the system into account, i.e. the power needed to compress the produced hydrogen and the power of the air compressor supplying air to the cathode channels of the fuel cell stack. The characteristics describing the dependence of the efficiency of the energy storage system in the form of hydrogen as a function of load were determined. The costs of electricity storage as a function of storage capacity were determined. The energy aspects of energy accumulation in lithium-ion cells were briefly characterized and described. The efficiency of the charge/discharge cycle of lithium-ion batteries has been determined. The graph of discharge of the lithium-ion battery depending on the current value was presented. The key parameters of battery operation, i.e. the Depth of Discharge (DoD) and the State of Charge (SoC), were determined. Based on the average market prices of the available lithium-ion batteries for the storage of energy from photovoltaic cells, unit costs of electrochemical energy storage as a function of the DoD parameter were determined.
