Effects of large-scale power to gas conversion on the power, gas and carbon sectors and their interactions

摘要: Abstract The increasing share of intermittent renewable electricity production leads to operational challenges in the electric power sector. Storage will be needed, among other options, ensure an efficient and reliable operation system. gas (PtG) concept provides a possibility store excess as such it can increase utilisation RES-based generation. methane, produced via PtG, stored system used e.g. for has much larger storage capacity compared current technologies. However, PtG introduces extra couplings between gas, carbon ( CO 2 ) sector is not known what effect these new interactions could be. Therefore, model been developed that includes analyse effects on sectors them. Based case study, found partially transfers flexibility problems, triggered by introduction generation, from Moreover, downward pressure prices observed. are generally smaller than those large-scale Also, complex inter-sector dependencies introduced through required process. If deployed at large scale, study relevant policy makers, regulators, energy markets’ participants operators.
