Optimal operation of a photovoltaic generation-powered hydrogen production system at a hydrogen refueling station

Design of a Pilot SOFC System for the Combined Production of Hydrogen and Electricity under Refueling Station Requirements

“…Hydrogen production (on‐site or off‐site) is a usual characterization criterion for HRSs, together with the state of the H 2 that is supplied to the station in an off‐site configuration (gas or liquid, in which case it is stored in an on‐site cryogenic tank, refilled by a liquid H 2 tanker) . Every HRS responds to particular sizing and operating needs , as it can be dimensioned to fulfill different H 2 demands and requirements, depending on its locations and builder's criteria: for instance, seasonal, daily, hourly‐following HRS demand, different selected levels of storage pressure (and thus, a number of compression steps) or the use of a cascade FCEV charging system , . Multiple HRS configurations are therefore possible , .…”

“…The higher the efficiency of it, the lower the H 2 price in order to be competitive in the marketplace. As a difference from previous optimization works about in‐situ H 2 generation, mainly based on SMR or electrolysis , , the current work uses a solid oxide fuel cell (SOFC)‐based system not only for the production of H 2 , but also for heat and electricity. Polygeneration and modulation of SOFC‐based systems have been previously studied, demonstrating feasibility, flexibility and high efficiency of multi‐purpose SOFC‐systems and potentially of their associated supply chain, if compared with centralized and distributed SMR systems .…”

Generation Coordination and Planning of New Power System Considering Industry Hydrogen Load

“…Traditional thermal power unit regulation has become difficult to adapt to a power system with a high proportion of renewable energy, and it is urgent to find alternative regulation methods [1]. Electricity to hydrogen technology can improve the flexibility of optimal operation of multi-energy systems, and there is an increasing discussion on the planning of electric/hydrogen unified energy systems [2]. In [3], a collaborative planning method was proposed for multi-regional integrated energy systems with combined cooling, heating, and power supply, simplified the heat network model, and established a capacity planning model for cooling, heating, and power trigeneration units; In [4], an equipment selection and capacity planning method was proposed for integrated energy systems considering the coupling of electricity, heat, and gas; In [5], a two-layer mixed integer planning model was proposed for regional electricity-hydrogen integrated energy systems.…”

A multi-model method to assess the value of power-to-gas using excess renewable

“…Hydrogen produced from P2G has a wide range of potential end uses, including power generation [7], [8], transportation service [9], [10], heat generation [11], [12], and as an industrial feedstock [13], [14] [15]. The application of P2G can be found at both local level and large-scale national level, such as adding valuable flexibility for micro grid [16] [17] and smart urban system [18], providing onsite hydrogen supply for refuelling stations [19] [20], [21] , and playing as the key enabler for national overall plan to decarbonise the whole energy systems [22]- [25]. The highest value markets for hydrogen would likely change over time.…”
