The future of hydrogen in Region Uppsala : A case study of an electrolyseras a node in the district heating network

Sammanfattning: This report aims to analyse how an electrolyser would benefit Region Uppsala in the transition to a more sustainable society and where it would be most beneficial to place it. The studied locations for placement werein Uppsala, Storvreta andKnivsta. The possibilities of how the residual products oxygen and residual heat could be utilized from the electrolysis process is investigated. The economic calculation includes incomes and expenses of all components in the electrolysis process on a yearly basis and on a 15-years period. The climate calculation includes the reduction of CO2-equivalent emissions when using the waste heat from the electrolyser into the district heating network. Since Uppsala got the bus storage in Kungsängen which makes it possible to utilize the hydrogen, the solar park which makes the electricity cheaper and a district heating network that can utilize the residual heat, it seems like Uppsala is the most beneficial place to build a hydrogen fuel station.
