Future developments in the components of SMES systems could make them more viable for other applications. Most notably the development of superconductors. Condensed matter physicists are always looking for superconductors with higher critical temperatures. In 2013 a group of researchers even found a superconductor that works at room temperature. This was stable for picoseconds, making it impractical but nevertheless proving that room temperature superconduc
At present, energy storage systems can be classified into two categories: energy-type storage and power-type storage [6, 7]. Energy-type storage systems are designed to provide high energy capacity for long-term applications such as peak shaving or power market, and typical examples include pumped hydro storage and battery energy

Figure 9.9.1 9.9. 1 : (a) In the Meissner effect, a magnetic field is expelled from a material once it becomes superconducting. (b) A magnet can levitate above a superconducting material, supported by the force expelling the magnetic field. Interestingly, the Meissner effect is not a consequence of the resistance being zero.
Nearly 70% of the expected increase in global energy demand is in the markets. Emerging and developing economies, where demand is expected to rise to 3.4% above 2019 levels. A device that can store electrical energy and able to use it later when required is called an "energy storage system".

MXene structure is strongly affected by the nature of the surface groups. For Ti 2 CBr 2, "a" lattice constant was equal to 3.32 Å, whereas it changed to 3.01 Å upon exchanging Br − with O 2− and the reaction with Te 2− produced MXene with "a" = 3.62 Å. This is attributed to the van der Waals radii and packing density of
