Exergy has to do with work potential or the quality of the energy vis. a vis. convertibility for work. A work potential (is measured from a reference state) and is available from the temperature differences, the differences in pressure, chemical processes, electromagnetic or strong-force potential,l, and many boundary energy storage mechanisms.  The most efficient work is possible when there is no new entropy generation.

The higher the temperature difference, the better the efficiency and exergy of a process.  One can have more exergy from a higher enthalpy phase during a transformation where the enthalpy is released, e.g., at the melting point, there is more exergy in the liquid than the solid at the same temperature.

MHI products reach very high temperatures in air and thus provide some of the highest source temperatures in an extremely versatile fashion. The higher temperatures possible with MHI products (heating elements, advanced materials, furnaces, steam units, airtorch, plasma) allow for high efficiencies and exergies. MHI also offers sub-assemblies in the form of heating elements, coils, and Airtorch devices

Manufacturing and process productivity are greatly improved with high-temperature availability (SmartPower from High Temperature). Link

Energy is always conserved, whereas exergy (a measure of the potential of that energy) is not.  The same amount of energy at 1900°C has more potential than when the energy is available at a lower temperature. The quality of energy as important as the quantity for determining what the energy can do for you.  MHI specializes in high-quality energy.  MHI products may be used to convert low-quality energy to high-quality energy.
