Thermal & Mechanical Storage Introduction:<\/strong><\/p>\n\n\n\n While battery storage dominates discussions around storage, there are storage systems other than electrochemical. Thermal and mechanical storage systems are the two other prominent storage solutions.<\/p>\n\n\n\n Prominent among mechanical storage solutions is pumped hydro storage in which electricity during non-peak periods is used to pump water up to a reservoir and the water runs down during peak periods to turn a turbine and generate electricity. Prominent among thermal energy storage for large-scale applications is storing heat in phase change materials (such as molten salt). In these systems, heat – or electricity converted to heat – melts the salt, and when the energy is needed, the salt is allowed to convert into a solid, when it releases the heat back again for use as heat or to run a turbine to generate power. <\/p>\n\n\n\n Pumped hydro systems have some large-capacity implementations worldwide. The Bath County Pump Station in the United States for instance is a massive 3000 MW of pumped storage hydroelectric power plant. A few CSP power plants use reasonably large phase change materials-based thermal storage capacities.<\/p>\n\n\n\n While pumped storage is a fairly well-established mechanical storage technology, technologies such as compressed air storage, and flywheel-based storage are less so in the context of large-scale renewable energy storage. Thermal storage solutions that use phase change materials are still undergoing evolution for large-scale use for power or heat storage. One PCM-based thermal storage segment where significant innovations are happening is in the use of water\/ice as a phase change material – many buildings worldwide are experimenting with using electricity to convert water into ice during non-peak power periods and using the ice to provide cooling during peak hours.<\/p>\n\n\n\n Other than simple heat storage systems (a residential hot water tank, for example) and pumped hydro storage, the use of other mechanical and thermal storage systems for large-scale heat or power storage so far has been quite selective and has been mainly experimented with and implemented in developed economies.<\/p>\n\n\n\n For the 2020-2030 period, innovations in this domain can be expected in ice-based PCM storage, utility-scale storage using thermal or mechanical systems, liquid energy storage, hybrid storage systems, compressed air, CO2-based thermal storage, and flywheel storage. Also, expect increasing use of digital technologies to integrate these storage solutions and optimise them with the rest of energy and power ecosystems.<\/p>\n\n\n\n The Thermal & Mechanical Storage Innovations & Startups Report provides insights on the following:<\/strong><\/p>\n\n\n\n For each startup, the following inputs are provided:<\/strong><\/p>\n\n\n\n The Thermal & Mechanical Storage Innovations Report is part of CLIMAFIX 500, a comprehensive global climate innovation and startup report. <\/p>\n\n\n\n\n
