Increases in global energy demand have been caused by increases in population and industrialization. Demands for energy production and storage will only increase as time continues. However, the use of non-renewables increasingly pollutes the air, and these non-renewables will eventually run out. This has inspired the advancement of renewable and sustainable energy production and storage capabilities. One major issue with renewable energy is intermittent power generation due to natural changes such as wind speeds, nighttime, and ocean currents. Natural gas does have the advantage of being able to continuously provide an energy stream. Storage of electrical energy from sources such as wind and solar is expensive due to the large size and relatively inefficient nature of batteries. While advancements have been made and electrical storage has improved over the years, solar in particular is still too expensive compared to other non-renewables. As a result, photovoltaic (PV) cells coupled with batteries are not an economically viable alternative to coal power at the present time. For this reason, concentrating solar power (CSP) has been popular for storing solar energy in the form of heat that can be used to run a steam engine.
