“…While these studies are inspiring, the interactions between the H 2 supply chain and the power sector, in many of the studies, exclude critical components in the H 2 supply chain. For example, some studies ignore the possibility of natural gas-based H 2 production from steam methane reformer (SMR) with or without carbon capture and storage (CCS) [22][23][24] . Second, most literature either do not consider some modes of H 2 transmission 22,25,26 or when it is included, the modelling of H 2 transmission is oversimplified by setting fixed lower and upper H 2 flow limits for each route [23][24][25]27 .…”

“…In addition, surplus hydrogen can be stored in hydrogen storage tanks. Large-scale hydrogen storage is one of the few low-carbon solutions that can balance the intermittency of wind and solar power generation [30]. On the other hand, the electricity produced by conventional energy and renewable energy is transmitted to the charging station through the electricity network to charge the batteries of FCHEVs.…”

With an increasing integration of traditional electric vehicles (EVs), the ensuing congestion and overloading issues have threatened the reliability of power grid operation. Hydrogen has been advocated as a promising energy carrier to achieve a low-carbon transportation and energy (trans-energy) systems, which can support the popularization of fuel cell hybrid EVs (FCHEVs) while enhancing the flexibility of power grids. In this paper, we propose an optimal scheduling framework for trans-energy systems that evaluates the merits of hydrogen supply chain from water electrolysis, compressed storage and transportation to FCHEV utilization. A detailed FCHEV model is established, and mileage is modeled as a function of the stored electricity and hydrogen mass. A stochastic programming-based scheduling model is formulated, which minimizes the total cost of unit commitment and hydrogen supply chain. Dijkstra algorithm is adopted to search the shortest path for hydrogen transportation. Case studies demonstrate that FCHEVs can reduce the operation costs of the trans-energy systems and facilitate the accommodation of renewable energy compared to traditional EVs.

There is growing interest in hydrogen (H 2 ) use for long-duration energy storage in a future electric grid dominated by variable renewable energy (VRE) resources. Modelling the role of H 2 as grid-scale energy storage, often referred as "power-to-gas-to-power (P2G2P)" overlooks the cost-sharing and emission benefits from using the deployed H 2 production and storage assets to also supply H 2 for decarbonizing other end-use sectors where direct electrification may be challenged. Here, we develop a generalized modelling framework for co-optimizing energy infrastructure investment and operation across power and transportation sectors and the supply chains of electricity and H 2 , while accounting for spatio-temporal variations in energy demand and supply. Applying this sector-coupling framework to the U.S. Northeast under a range of technology cost and carbon price scenarios, we find a greater value of power-to-H 2 (P2G) versus P2G2P routes. P2G provides flexible demand response, while the extra cost and efficiency penalties of P2G2P routes make the solution less attractive for grid balancing. The effects of sector-coupling are significant, boosting renewable energy generation by 12-55% with both increased capacities and reduced curtailments and reducing the total system cost (or levelized costs of energy) by 6-14% under 96% decarbonization scenarios. Both the cost savings and emission reductions from sector coupling increase with H 2 demand for other end-uses, more than doubling for a 96% decarbonization scenario as H 2 demand quadraples. Moreover, we found that the deployment of carbon capture and storage is more cost-effective in the H 2 sector because of the lower cost and higher utilization rate. These findings highlight the importance of using an integrated multi-sector energy system framework with multiple energy vectors in planning energy system decarbonization pathways.
