10 GW HTS DC Superconducting Transmission Model

Underwrite 77 Kelvin liquid nitrogen cooled high-temperature superconducting (HTS) DC underground power cables transmitting 10 Gigawatts of renewable wind power across 500 km within a compact 1-meter pipe trench (with 0.5% electrical losses vs 8% on overhead AC lines). Model grid transmission wheeling tariffs ($0.012/kWh moved), and 30-yr IRR.
