Integrated energy system based on hydrogen storage

Integrated energy systems


Fossil fuels reserves are dwindling; moreover, the use of fossil fuels leads to global warming due to CO2 and NOx emissions, and so the decarbonisation is imperative for the world economy by a shift to clean or low carbon electricity such as renewable energy resources. When the shift to clean electricity is increasing, the electrification of transport, buildings and industrial processes powered by the clean electricity would be the main pillars of the integrated energy system. Current fossil fuels based energy systems have the established infrastructure to meet the load demands, but now the challenge is to create an equally or more flexible integrated energy systems with increasing amounts of fluctuating renewable energy supplies. Because of the intermittency of the renewable energy supply, a significant driver of the design of integrated energy systems is the reliable power supply to the consumer under varying atmospheric conditions. Local energy storage is usually necessary to guarantee supply. The required availability of supply, ranging from being grid-like to being tolerant of outages lasting some hours, then becomes a significant factor in the design and cost of the energy system.

The basic premise is that energy is to be delivered as electricity or gas to consumers with a defined requirement for the reliability of supply, ranging from individual dwellings to remote industries to small communities, with an upper power limit perhaps in the low megawatt range. Increasingly, as hydrogen fuel-cell and electric vehicles come to market, the supply of hydrogen as a fuel in addition to electricity will be required, creating an opportunity for integrated energy systems based on twin electricity and hydrogen energy vectors. A further chance of hydrogen production is through the connection of fast-response electrolysers to soak up excess grid capacity and so contribute to grid stabilisation. Energy systems involving hydrogen tend to be complicated because of the transformations involved in its generation, storage and end-use. Modelling is a critically important stage in the design of such a system, both at the component and system level, where all the components, such as a photovoltaic array, wind turbine, electrolyser, hydrogen storage and fuel cell, need to interface and work together optimally.




The scope of this project is multidisciplinary and  can explore the following topics but not limited to, such as:

  • Remodel the energy value chain by integrating low-carbon energy sources along with hydrogen
  • Modelling and optimisation of the integrated energy systems
  • Transient and dynamic responses of system components at stochastic generation and load demand for smart energy systems
  • Sizing and dynamic control for distributed and centralised energy systems based on ML and deep learning
  • Blockchain in the integrated energy system
  • Degradation study especially MEA in hydrogen technologies such as electrolyser and fuel cell
  • Stack design and heat management of PEM electrolyser and fuel cell
  • Water management and uptake of PEM electrolysers
  • Design the hydrogen storage tank to increase the thermodynamics, reaction kinetics, and so on
