“…Superconductors can be used in motors with a wide range of applications in vehicles and industrial devices. They can provide light weight, smaller size, low energy consumption and high-efficiency of the motors [32,36,37] by making stronger magnetic fields that rotate rotors with stronger force, lead to a reduction of the amount of iron used in the motor, increase the torque and reduce the motor size [33,38]. In large-scale vehicles, such as a ship, superconductors can save space and considerably reduce noise [33].…”

Hydrogen as an energy carrier is a promising alternative to fossil fuels, and it becomes more and more popular in developed countries as a carbon-free fuel. The low boiling temperature of hydrogen (20 K or −253.15 °C) provides a unique opportunity to implement superconductors with a critical temperature above 20 K such as MgB2 or high-temperature superconductors. Superconductors increase efficiency and reduce the loss of energy, which could compensate for the high price of LH2 to some extent. Norway is one of the pioneer countries with adequate infrastructure for using liquid hydrogen in the industry, especially in marine technology where a superconducting propulsion system can make a remarkable impact on its economy. Using superconductors in the motor of a propulsion system can increase its efficiency from 95% to 98% when the motor operates at full power. The difference in efficiency is even greater when the motor does not work at full power. Here, we survey the applications of liquid hydrogen and superconductors and propose a realistic roadmap for their synergy, specifically for the Norwegian economy in the marine industry.
