Abstract

This study is based on the initiative from Håbo municipality regarding a conversion from fossil fuels to renewable alternatives. The purpose with this study is to evaluate various systems regarding a reliable fossil free backup-power facility to possibly be implemented in powering a pump-station in Håbo municipality. The current backup power plant is powered by a traditional diesel generator. Furthermore, the report seeks to analyze the emissions of the whole facility, analyze the accessibility on the market and also present a synoptic economic analysis. The methodology of the study consists of systematic studies with a wide spectrum of choices which culminates in a comparative of all the technologies and systems. Thereafter, relevant and applicable alternatives were evaluated further, which led to three favorable systems to be implemented in Håbo municipality. These systems were solar panels combined with lithium ion-batteries, HVO (biofuel) combined with a generator and finally hydrogen storage combined with a fuel cell. The study result in a comparison regarding advantages and disadvantages of the three different systems in connection to future possibilities, availability, economy and start-up time. In conclusion, all systems can be implemented however the HVO-system is preferable regarding the economical aspect. The other systems have great potential in the future.
