Move that Hydrogen: A closer look at the various Hydrogen Transportation Pathways
Sertan Cansu, Fluor
Direct electrification of processes within industrial and mobility sectors is often an option to achieve carbon neutral solutions. However, processes such as steel making, long-haul aviation and shipping are hard-to-decarbonise sectors and require molecules for energy input rather than electrons due to their specific chemical properties, energy density and storability.
Hydrogen has been identified as a key input for reaching decarbonisation targets by many countries. To create a climate-neutral Europe, the European Hydrogen Backbone (EHB) initiative has been established by the participation of thirty-one energy infrastructure operators. The EHB aims to accelerate the EU’s decarbonisation journey by defining the critical role of hydrogen infrastructure.
The EU’s strategy aims to install electrolysers within Europe, as well as promoting the large-scale import of clean hydrogen from regions with a lower cost profile.
Large monetary funds are being set up for clean hydrogen production.
Another key component of the clean hydrogen economy that is often overlooked is the challenge associated with large-scale transportation of clean hydrogen and its derivatives from low-cost production sites to end-markets.
What is the best way (safe, economical, scalable) to transport hydrogen across continents? Ammonia, gaseous (compressed) hydrogen, liquefied hydrogen, or Liquid Organic Hydrogen Carriers (LOHC)?
A holistic study that covers all the abovementioned pathways is considered to evaluate the challenges and opportunities associated with each path. Due to different maturity of each process and availability of transportation means, a high-level evaluation and comparison of these pathways rather than the exact costs, will be presented.
Desublimation for CO2 Capture
Werner Friedl, Kelvion Thermal Solutions
Desublimation is a not widely known substance separation method for gas mixtures. However, at KTS, desublimation is a well-established process for which we have been delivering equipment for more than 60 years for several applications. This successful history started in the 1950’s with the separation of phthalic anhydride as a product from a gas phase reaction. During the last few decades we have been expanding the range of application, finding new substances which can be separated using desublimation. Carbon dioxide is one of these applications, for which we have not only carried out a deep theoretical work with universities and well-renowned international institutes, but also, we have delivered desublimators for a full-scale pilot plant where our desublimators achieved the stringent requirements of the customer. We will present the results of this theoretical work, as well as the outcomes of the pilot plant.
Digital Twins with Rigorous Separation Modelling – Key to Optimising Process Operations
Tom Ralston, MySep Pte Ltd
Increasingly, process digital twins are being applied across oil & gas facilities to optimize operations. These digital twins are usually based on commercial process simulation platforms with a detailed representation of the key process operations. In upstream, midstream and downstream processing, operators target maximization of facility revenue and profit, without compromising safety or reliability. Process engineering teams will have to build a digital twin which represents all the important unit operations whilst embodying sufficient rigour to capture the fundamental system constraints. Phase separation is a key unit operation in many oil & gas processes – how can that be digitalized?
The presentation will include demonstration of a steady-state production digital twin, showing how it can be used to understand the real operational constraints, and the revenue impact these have on facility operations. Additional material will touch on dynamic digital twins in production and examples from LNG and Downstream sectors.
