"Power-to-Gas technology allows electricity from renewable sources to be stored as a synthetic natural gas (SNG) - either hydrogen or methane. These can be used as transport fuels in fuel cells and internal combustion engines. Use of this technology and the resulting fuels for mobility is of interest because it may help to address challenges in the transport sector as well as in the electricity grid. For transport, it holds the prospect of delivering a climate-neutral fuel, reducing the need to import fossil fuel-based energy, and reducing CO2 and other pollutant emissions from vehicles. It also does not require cropland for fuel production and thereby circumvents the "food vs. fuel" issue that burdens some biofuels. With increasing shares of renewable energy in the grid electricity mix, storage becomes more and more important in order to balance fluctuating renewable power production with demand patterns from residential, commercial and industrial users. The high energy densities of hydrogen and methane, coupled particularly with the existing natural gas infrastructure (pipelines, storage facilities), gives them energy storage capacity on the order of terawatt hours, which is beyond that of all other storage technologies used today. This opens the prospect of storing renewable energy for weeks and months, and across seasons, and thus facilitating the integration of renewable energy into the grid. This master thesis explores and compares the service cost of mobility based on complete pathways (fuel production, storage, transport, refueling, and vehicles) for both hydrogen and methane. Overviews of the key technology elements are provided, and energetic and environmental aspects are also analyzed."
