Room-temperature superconductors have the potential to revolutionize the energy industry. What is a Room-Temperature Superconductor? Superconductors are a special class of materials that pose zero-resistance electron transmission under a specific threshold temperature typical to the material concerned.
“There’s always been the hope of making a room-temperature superconductor, it’s sort of a holy grail.” And like a modern-day Sir Galahad, researchers from South Korea believe that search is over, publishing two papers in July 2023 detailing a new material that’s supposedly a superconductor at room temperature and ambient pressure.
Is it possible to make a material that is a superconductor at room temperature and atmospheric pressure? A room-temperature superconductor is a hypothetical material capable of displaying superconductivity above 0 °C (273 K; 32 °F), operating temperatures which are commonly encountered in everyday settings.
Figure 1 shows the timeline of development of high temperature superconductors; scientists are coming closer to a superconductor that can be used at room temperature. The mind abounds with applications of such a material: lossless power transmission, levitating trains, and more efficient electronics are the obvious stuff.
Superconducting magnetic energy storage (SMES) systems store energy in the magnetic field created by the flow of direct current in a superconducting coil that has been cryogenically cooled to a temperature below its superconducting critical temperature. This use of superconducting coils to store magnetic energy was invented by M. Ferrier in 1970.
Superconducting batteries are the real energy gain from high-T c superconductors. There are, however, limits to this approach. A back of the envelope calculation reveals that this approach may not completely revolutionize the energy economy.
Superconducting energy storage is currently used to smooth out short-term fluctuations in the electric grid, but it still remains relatively niche because it takes a lot of energy to keep superconductors cold.

As long as the superconductor is cold and remains superconducting the current will continue to circulate and energy is stored. The (magnetic) energy stored inside a coil comes from the magnetic field inside the cylinder. The energy of a magnetic field is proportional to B 2, hence the total energy goes like B 2 x Volume. Using the magnetic ...
A room-temperature superconductor is a hypothetical material capable of displaying superconductivity above 0 °C (273 K; 32 °F), operating temperatures which are commonly encountered in everyday settings.

Niobium–titanium (NbTi) alloys, that operate at liquid helium temperatures (2–4 K), are the most exploited for storage. The use of superconductors with higher critical temperatures (e.g., 60–70 K) needs more investigation and advancement. Today''s total cooling and superconducting technology defines and builds the components of an SMES device.
A high-T c superconductor would allow for efficient storage (and transport) of power. Batteries are also much easier to keep refrigerated if necessary, and there are greater efficiency gains to be had. Superconducting batteries are the real energy gain from high-T c superconductors. There are, however, limits to this approach. A back of the ...
