In addition to traditional cryogenic and high-pressure tanks, an alternative approach involves utilizing porous materials such as activated carbons within the storage tank. The adsorption behaviour of hydrogen in porous structures is described using the Dubinin-Astakhov isotherm. To model the flow of hydrogen within the tank, we rely on the equations of mass conservation, the Navier-Stokes equations, and the equation of energy conservation, which are implemented in a computational fluid dynamics code and additional terms account for the amount of hydrogen involved in sorption and the corresponding heat release. While physical models are valuable, data-driven models often offer computational advantages. Based on the data from the physical adsorption model, a data-driven model is derived using various machine learning techniques. This model is then incorporated as source terms in the governing conservation equations, resulting in a novel hybrid formulation which is computationally more efficient. Consequently, a new method is presented to compute the temperature and concentration distribution during the charging and discharging of hydrogen tanks and identifying any limiting phenomena more easily.","lang":"eng"}],"publication_status":"published","author":[{"last_name":"Klepp","full_name":"Klepp, Georg Heinrich","first_name":"Georg Heinrich","id":"49011"}],"publisher":"Elsevier BV","publication":"Energy : the international journal ; technologies, resources, reserves, demands, impact, conservation, management, policy","status":"public","doi":"10.1016/j.energy.2024.132318","date_created":"2024-07-31T14:23:52Z","department":[{"_id":"DEP6017"}],"date_updated":"2024-08-01T08:16:04Z","user_id":"83781","type":"scientific_journal_article","citation":{"din1505-2-1":"<span style=\"font-variant:small-caps;\">Klepp, Georg Heinrich</span>: Modelling activated carbon hydrogen storage tanks using machine learning models.
