Hydrogen is considered one of the main actors in achieving the decarbonization of the energy sector by 2050. Whilst hydrogen production technologies are already available at an industrial scale, cost-effective solutions for large-scale hydrogen transmission remain limited. In this context, the SuperConducting Energy Pipeline (SCEP) is studied. This technology is capable of simultaneously transporting electricity and liquid hydrogen through a superconducting cable surrounded by an annular pipeline containing liquid hydrogen. Energy System Optimization Models (ESOMs) enable the creation of scenarios to assess the cost-competitiveness of emerging technologies thanks to their detailed techno-economic characterization of energy technologies. This work aims to evaluate the cost-competitiveness of SCEP technology compared to conventional transmission options.
