Flexible and robust hydrogen production and storage in Lysekil
The project aims to evaluate future scenarios for hydrogen supply to Preem's refinery in Lysekil and present opportunities for Preem's future refinery with a higher degree of electrification. In the future, hydrogen production is planned to occur not only through steam reforming but also through electrolysis.
The project aims to define three different scenarios for future hydrogen needs in 2030/2040 (based on Preem's sustainability vision) and includes an evaluation of possible production mixes regarding the production of electrofuels to supplement the production based on biomass. The hydrogen can be both blue and green, and the scenario with the greatest hydrogen demand involves the case with the highest production of electrofuels.
To handle future fluctuations in production and hydrogen demand at the facility, an analysis of the technical conditions for hydrogen storage above/under ground is planned, evaluating both existing rock caverns and the possibility of establishing new ones, along with an estimation of approximate costs for establishing hydrogen storage. This also includes an estimation of power requirements and possible limitations in transmission capacity.
Based on the new energy and material flows expected at the refinery, a symbiosis mapping is planned to determine the opportunities to utilize byproducts from electrolyzers in the form of oxygen and heat, and to determine how the different scenarios affect these opportunities. This also includes an evaluation of the possibility of establishing a heat storage facility – where rock caverns could also be considered – to enhance opportunities for industrial symbiosis. The presented scenarios, as well as identified options for hydrogen storage for Preem's future refinery in Lysekil, will then be compared with other hydrogen nodes in Sweden to primarily identify similarities and differences in conditions. The project will strive for active knowledge exchange regarding hydrogen storage and related symbiosis activities with other clusters in Sweden where hydrogen storage is under investigation to highlight relevant similarities and differences regarding different locations.
Goals
The goals of this study are to:
- Present three scenarios for Preem's refinery in 2030/2040 that simultaneously fullfill Preem's sustainability vision.
- Present possible solutions for hydrogen storage above/underground and cost estimations for these.
- Quantify byproducts generated from the electrolyzers (oxygen and heat) in the different scenarios and quantify the effects of utilizing these in industrial symbioses, including an action plan for the most likely scenario in the near term based on conducted symbiosis workshops. Also evaluate the possibility of including a heat storage facility.
- Compare a future hydrogen node at Preem's refinery (including hydrogen storage) with other planned hydrogen nodes in Sweden, focusing on Western Sweden and potential regional coordination/synergies. This also includes identifying conclusions that can be used for other nodes regarding energy storage solutions and symbiosis, etc.
- Establish a knowledge platform for exchange regarding hydrogen storage in the region (this could complement the work done within the framework of the project "Regional cooperation on hydrogen").
