Hybrid hydrogen refuelling station and peaker plant using renewables. Multi-objective MIQCP for clean integrated energy system. Export of electricity to the grid during peak periods. The power and transport sectors are responsible for significant emissions of greenhouse gases.
Hydrogen storage is for the stabilisation of the intermittent renewable energy sources. Three different configurations namely Solar-Hydrogen, Wind-Hydrogen and Hybrid Solar-Wind-Hydrogen system were analysed. The Hybrid Energy system stand a better chance than others in terms of levelised cost of energy.
Increasing renewable and nuclear generation capacity by an additional 7.5%, compared to Aurora’s base case, would produce the amount of hydrogen needed to fire peaking power plants by 2035. Replacing gas-fired peakers with hydrogen could save up to £90bn, compared to relying on short-duration energy storage for low-carbon flexibility.
Current research reviews on hydrogen energy have focused on hydrogen production [, , , ] and storage [, , ], which usually place more emphasis on specific technologies but less on the role of hydrogen energy in power systems and the coupling of hydrogen energy and power systems.
Application of hydrogen energy on the load side It can be used as a power source for the transport industry, as a fuel for combined heat and power systems or as an industrial raw material for the production of industrial products. Fig. 13 shows the application of hydrogen energy on the load side.
After a high proportion of renewable energy generation is connected, especially with the volatility of wind power, hydrogen energy has a high storage capacity, long storage cycles, high flexibility, etc. Fig. 12 illustrates the ability of hydrogen energy to cut peaks and fill valleys across seasons and regions.

Abstract: For the future development of an integrated energy system (IES) with ultra-high penetration of renewable energy, a planning model for an electricity-hydrogen integrated energy system (EH-IES) is proposed with the considerations of hydrogen production and storage technologies. In this EH-IES, a reasonable power to heat and hydrogen (P2HH) …
The levelised cost of hydrogen LCOH, given as a cost per energy unit of hydrogen generated (£/MWh H 2 HHV) or as a cost per mass unit of produced hydrogen (£/kg), is the discounted lifetime cost of constructing and running a facility of hydrogen production. It includes all pertinent expenses incurred during the lifespan of system, such as CAPEX, OPEX …
Low hydrogen prices (e.g. 0.9 €/kgH 2) indicated that hydrogen production is only favourable in the morning when electricity prices are lower [30].
