Sammendrag
Combining liquid hydrogen and superconducting cables
presents a unique opportunity for a more decarbonized
world. The European project SCARLET has been launched
to demonstrate inter alia the feasibility of an MVDC hybrid
system that distributes hydrogen and bulk electricity in the
same infrastructure. Liquid hydrogen at 20 K is perfectly
suited for cooling MgB2 compact cables that are
superconducting below 39 K.
After a short presentation of the project, designs of MVDC
MgB2 cables systems capable of transmitting 1 GW are
discussed. A type test and long-term testing will be
conducted to demonstrate the maturity and safety of the
system.
