Sažetak
TThe European Union aims to be climate-neutral by 2050, i.e., an economy with net-zero greenhouse gas emissions. This goal is compliant with European Green Deal and the European Union’s commitment to global climate action under the Paris Agreement. Hydrogen is seen as an important part of the solution to achieve this goal, but the positive impact of hydrogen on the mitigation of greenhouse gas emission relies heavily on the type of technology used to produce it. Methane pyrolysis is the thermal decomposition of natural gas into hydrogen and solid carbon. It produces CO2-free hydrogen, also known as turquoise hydrogen. Methane pyrolysis technologies fall into three categories: thermal, catalytic, and plasma decomposition. The technical challenges in the development of methane pyrolysis technology include the high energetic requirements and the separation of solid carbon in the reactor. This thesis provides a comprehensive overview of methane pyrolysis technologies currently under development. At the moment, plasma methane pyrolysis is the most advanced technology. Monolith Materials has been operating an industrial scale thermal plasma plant since 2020. The other technologies mentioned are still under development and are intended for pilot projects. For every tonne of hydrogen produced, three tonnes of solid carbon are also produced as a byproduct. Depending on the technology, methane pyrolysis can produce different types of solid carbon products, such as carbon black, carbon nanotubes, carbon nanofibers, graphite, graphene, etc. In this thesis, different types of carbon products that could be produced by methane pyrolysis are described in detail, especially their properties, most common present uses and possible future uses. The focus is on carbon black, as this is the largest and oldest market. However, if methane pyrolysis is carried out on an industrial scale, large amounts of solid carbon will be produced, and new markets for carbon products have to be found.
