Fluid challenges in PtX

Power-to-X involves converting surplus renewable energy into storable and transportable forms, such as hydrogen, synthetic fuels, chemicals and heat. As such Power-to-X technologies are at the forefront of sustainable energy transformation and play a critical role in balancing the future energy systems with multiple fluctuating energy sources. Many of the challenges in developing Power-to-X technologies rely heavily on advanced fluid dynamics principles. Understanding fluid flow, heat and mass transfer, and the interaction between different phases are essential for optimizing the performance and scalability of Power-to-X systems.

This seminar will offer insights into the latest advancements in Power-to-X technologies, with a focus on the fluid dynamics aspects that are crucial for their development. Experts from academia and industry will share their knowledge on topics such as electrolysis, catalytic processes, system integration and the role of fluid dynamics in enhancing the efficiency and stability of Power-to-X operations.

Note: MAN ES is 5 min. walk from Metro station Enghave Brygge. Car parking requires a permit at MAN ES. Dansis visitors can get a parking permit free of charge at the reception.

11:15 Alkaline water electrolysis: 3D multiphysics modelling
Ahsan Iqbal, Green Hydrogen Systems
Alkaline water electrolysis has been used in H2 production for many years. In industries, the efficiency of electrolysis process is described by specific energy requirement i.e. kwh of electrical energy used to produce 1kg of H2. Theoretically at high temperatures efficiency of electrolysis is high. However, as of any other technology, AEW has its limitations e.g. use of diaphragm to separate anode and cathode. Diaphragm can only work under certain temperature. Therefore, properties of diaphragm are one of the factors that limits the operating temperature in AWE

Pourya Foroogh, Aarhus University
Alkaline water electrolyzers represent a rich physical problem where multiphase fluid flow, mass transfer, and electrochemical reactions are among the contributing factors. CFD is a tool to shed light on the complex physics of the problem and optimize electrolyzer cells. The present talk introduces an on-going simulation campaign at Aarhus University aiming to understand the two-phase flow in alkaline electroyzers with porous electrodes at both cell and micro (pore and bubble) scales and to improve the performance.
