Commercial Applications

Until recently the cost of fuel cells for terrestrial applications was prohibitive. Recently, several companies have begun developing high-performance, long-life and cost-effective fuel cell systems, and commercial units are now becoming available for stationary power generation. These systems can often be operated in conjunction with other energy systems to increase overall operational efficiency. A recent technology demonstration project at the University of Louisiana at Lafayette involved the installation, operation and analysis of a fuel cell and a desiccant dehumidification system, which is considered a good combination for the hot, humid climate of the U.S. Gulf coast. The three-year project involved technology assessment, hardware selection and procurement, installation, and operation of the two systems, followed by a performance analysis. The results were reported in a regional symposium. This paper describes the project, focusing on system operation and the results obtained, and predicts future possibilities for integrated energy systems of this type.

Parametric Studies

In this paper, a renewable-based integrated energy system is developed, analyzed, and optimized to achieve better performance. The present system is designed to be driven by concentrated solar thermal and biomass energies. Biomass fuel is used as the backup source of energy when the solar energy is not available. The system is designed to produce electricity, cooling, and hydrogen. The power output of the system is provided by solar-driven regenerative helium gas turbine during day time and from biomass gasification driven solid oxide fuel cell (SOFC) unit at night time. The fuel cell stack number is estimated as to provide the same net power. The system operates at energy and exergy efficiencies of 39.99% and 27.47%, respectively, at the optimal point selected based on the optimization analysis. The parametric studies on performance and environmental impact assessment are performed to investigate the effects of several operating parameters on the system performance.

Renewable Energy Generation

Integrated energy systems have become an area of interest as with growing energy demand globally, means of producing sustainable energy from flexible sources is key to meet future energy demands while keeping carbon emissions low. Hydrogen is a potential solution for providing flexibility in the future energy mix as it does not emit harmful gases when used as an energy source. In this paper, an integrated energy system including hydrogen as an energy vector and hydrogen storage is studied. The system is used to assess the behaviour of a hydrogen production and storage system under different renewable energy generation profiles. Two case studies are considered: a high renewable energy generation scenario and a low renewable energy generation scenario. These provide an understanding of how different levels of renewable penetration may affect the operation of an electrolyser and a fuel cell against an electricity import/export pricing regime. The mathematical model of the system under study is represented using the energy hub approach, with system optimisation through linear programming conducted via MATLAB to minimise the total operational cost. The work undertaken showcases the unique interactions the fuel cell has with the hydrogen storage system in terms of minimising grid electricity import and exporting stored hydrogen as electricity back to the grid when export prices are competitive.
