Contribution to Carbon Neutrality by Deep Underground Exploration using High-temperature Superconducting Quantum Sensing

With the advent of the carbon-neutral society, there is a growing need for underground exploration technology based on quantum sensing using high-temperature superconductors. In particular, deep and highly accurate electromagnetic surveys are required for exploration of hydrothermal reservoirs for geothermal power generation and monitoring technology for carbon dioxide capture and storage (CCS). This report describes the high-temperature superconducting SQUID technology and its role in the new society of green transformation (GX) and carbon neutrality.
