There are high expectations in Sweden to make transitional changes in industry, transport, and energy sectors utilising hydrogen to cut green-house gas emissions. The hydrogen considered will be based on hydrolysis of water where hydrogen gas (H2) will be the main product, but in the process oxygen (O2) is also an output along with some heat.
This report focuses the opportunities for using the oxygen resulting as a by-product from the electrolysers as part of the new hydrogen investments done in Sweden.
The total oxygen production in Sweden in 2020 was about 1.4 million tonnes. The volumes of oxygen produced as a by-product from the electrolysers in the Swedish hydrogen scenarios is about 7.5 million tonnes of oxygen in 2030 and almost 19 million tonnes of oxygen in 2045.
This report looks at opportunities for productive uses for the oxygen and highlights some of the challenges and gaps of knowledge.
