Industrial facilities are a unique type of end-user. They are large centralised consumers whose production costs are largely dependent on energy procurement. Lowering their production costs can lead to a more competitive product. They have high flexibility potential since they are easier to control and automate than other end-users. They can also individually participate in the energy markets. The main concepts, that the industrial facility will employ to achieve its flexibility potential, are demand response and integrating and shifting between multiple energy vectors. Industrial facilities are responsible for emitting their local emissions, meaning that they have to buy them on the emissions market adding additional cost to their production process. In order to reduce their local emissions and carbon footprint as a whole this thesis proposes switching from traditional fossil fuels to hydrogen technologies. They provide even more flexibility to the system since they can use excess electricity to produce hydrogen, or they can consume hydrogen to produce electricity and heat. Hydrogen can also be stored for future use. With a combination of hydrogen technologies and renewable energy sources, the industrial facility managed to almost completely reduce its carbon footprint while completely removing local emissions. From an economical point of view current hydrogen technologies, on average, are still not up to par with traditional. Future hydrogen technologies, reported in the literature, showcased better results depending on future price trends. The most promising benefit of the hydrogen-based system was that it was not very sensitive to market price changes since it could have high autonomy from the rest of the power system.
