The design studies on the force-free helical-type fusion reactor (FFHR) have been carried out with collaborations between universities and the National Institute for Fusion Science in Japan. The output of the electric power was optimized to 1 GW. Co-generation of hydrogen and electricity by steam electrolysis was applied. One-hundred tons per day of liquid hydrogen and 824 MW of electricity can be produced during off-peak time. The applicability for a 1 GW-class hybrid energy transfer line of hydrogen and electricity was investigated. The target distance of the hybrid energy transfer line was 100 km. A hydrogen refrigeration station was placed at intervals of every 10 km. The rated current and withstand voltage of the DC power lines were 10 kA and 100 kV respectively. To keep the liquid state of hydrogen present throughout the unit section, the temperature and pressure of the inlet points were set to 17 K and 0.4 MPa respectively. When the heat leak into the liquid hydrogen was 1.0 W/m (expected value), the temperature at the outlet was 18.1 K. The power consumption of the 20 kW-class refrigerator was estimated to be 1.32 MW. The total power consumption for the hybrid energy transfer line of 100 km in length was 13.2 MW. This value is equivalent to 1.3% of the transport capacity of 1 GW.
