In some areas, the problem of wind and solar power curtailment is prominent. Hydrogen energy has the advantage of high storage density and a long storage time. Multi-energy hybrid systems including renewable energies, batteries and hydrogen are designed to solve this problem. In order to reduce the power loss of the converter, an AC-DC hybrid bus is proposed. A multi-energy experiment platform is established including a wind turbine, photovoltaic panels, a battery, an electrolyzer, a hydrogen storage tank, a fuel cell and a load. The working characteristics of each subsystem are tested and analyzed. The multi-energy operation strategy is based on state monitoring and designed to enhance hydrogen utilization, energy efficiency and reliability of the system. The hydrogen production is guaranteed preferentially and the load is reliably supplied. The system states are monitored, such as the state of charge (SOC) and the hydrogen storage level. The rated and ramp powers of the battery and fuel cell and the pressure limit of the hydrogen storage tank are set as safety constraints. Eight different operation scenarios comprehensively evaluate the system’s performance, and via physical experiments the proposed operation strategy of the multi-energy system is verified as effective and stable.

Load Demand

This paper presents the detailed modeling of various components of a grid connected hybrid energy system (HES) consisting of a photovoltaic (PV) system, a solid oxide fuel cell (SOFC), an electrolyzer and a hydrogen storage tank with a power flow controller. Also, a valve controlled by the proposed controller decides how much amount of fuel is consumed by fuel cell according to the load demand. In this paper fuel cell is used instead of battery bank because fuel cell is free from pollution. The control and power management strategies are also developed. When the PV power is sufficient then it can fulfill the load demand as well as feeds the extra power to the electrolyzer. By using the electrolyzer, the hydrogen is generated from the water and stored in storage tank and this hydrogen act as a fuel to SOFC. If the availability of the power from the PV system cannot fulfill the load demand, then the fuel cell fulfills the required load demand. The SOFC takes required amount of hydrogen as fuel, which is controlled by the PID controller through a valve. Effectiveness of this technology is verified by the help of computer simulations in MATLAB/SIMULINK environment under various loading conditions and promising results are obtained.

The present international socio-economic drive for renewable energy use for sustainable development with environmental protection directs attention to hydrogen as energy carrier. Hydrogen production and storage, and fuel cell (FC) technologies have been intensively worked on in Europe including European Commission (EC) supported projects via Framework Programs (FPs), as well as various national and international cooperative programs including those of International Energy Agency (IEA) and International Partnership for Hydrogen Economy (IPHE). The hydrogen storage is required for transport applications as dense as possible to achieve high gravimetric and volumetric density. The storage of hydrogen in liquid, gas and solid forms are associated with low temperature cooling, higher pressures up to 700 bar and integrated higher volume and weight, respectively. The liquid and pressurized gas storage systems are relatively advanced in present applications. On the other hand, the system safety and reliability, hence the public acceptance as well as economic feasibility have been the main drives for solid and hybrid hydrogen applications. The use of solid hydrogen is predicted by the automotive industry to ultimately dominate the hydrogen transport application market. The bottleneck in solid hydrogen application is metal hydride production to meet the quantitative targets for vehicles mainly following the US DOE goals set for years up to 2015. System requirements need also be met for a present target of e.g. 75kWel fuel cell cars aiming at a 400km driving distance with 4 kg of hydrogen. This necessitates a gravimetric storage density of over 6 wt. per cent. The present paper will address the hydrogen storage tank system for on-board applications including storage tank materials, system design, production technologies and system safety. An overview will be presented on the current state-of-the-art of European and international progress on storage materials integrated into on-board storage tank system. The European current programs on hydrogen storage technologies for transport applications including design, safety and system reliability will be addressed.

Mining operations in remote locations rely heavily on diesel fuel for the electricity, haulage and heating demands. Such significant diesel dependency imposes large carbon footprints to these mines. Consequently, mining companies are looking for better energy strategies to lower their carbon footprints. Renewable energies can relieve this over-reliance on fossil fuels. Yet, in spite of their many advantages, renewable systems deployment on a large scale has been very limited, mainly due to the high battery storage system. Using hydrogen for energy storage purposes due to its relatively cheaper technology can facilitate the application of renewable energies in the mining industry. Such cost-prohibitive issues prevent achieving 100% penetration rate of renewables in mining applications. This paper offers a novel integrated renewable–multi-storage (wind turbine/battery/fuel cell/thermal storage) solution with six different configurations to secure 100% off-grid mining power supply as a stand-alone system. A detailed comparison between the proposed configurations is presented with recommendations for implementation. A parametric study is also performed, identifying the effect of different parameters (i.e., wind speed, battery market price, and fuel cell market price) on economics of the system. The result of the present study reveals that standalone renewable energy deployment in mine settings is technically and economically feasible with the current market prices, depending on the average wind speed at the mine location.

Despite the great uncertainty in the timing that analysts indicate in their forecasts, the transition to a new energy system is inevitable. This transition does not mean an instant and complete abandonment of hydrocarbon energy, but its gradual replacement with energy sources that do not pollute the environment during operation, with a low «carbon footprint». And the role of hydrogen energy in this process is significant. The purpose of the article is to review and assess the current state of hydrogen energy in Russia, in particular on solid oxide fuel cell (SOFC) technologies. The article contains references from strategic and long-term planning documents in the field of energy, indicating the main directions of development of hydrogen energy in the Russian Federation; hydrogen energy technologies, including fuel cell technologies (FC): general characteristics, scope of their application, five main types of FC, and in more detail - the general characteristics and scope of SOFC as the most promising from the point of view of practical application and the level of technological development. The monitoring of publication activity on the subject of the SOFC was carried out, the methodology of which is based on the use of advanced search tools of the international scientific citation systems Web of Science and Scopus by keywords. The dynamics of the publication activity of scientists who conducted research on the subject of SOFC for the period 1990-2020 is presented; monitoring of the publication activity of 10 world leaders in scientific research in the field of SOFC for the period 2010-2020 and separately – the rating of Russian scientific organizations for the period 1990-2020. The results of the research of foreign scientists involved in this topic within the framework of megagrant projects, as well as the results of competitive selections within the framework of state support for young Russian scientists (grants and scholarships of the President of the Russian Federation) are analyzed.
