Elstor has developed a modular thermal energy storage system that stores electricity from the cheapest hours of the day as heat (500°C). That stored energy can then be flexibly discharged as steam and heat for utility, district energy, and industrial applications — improving efficiency, cutting costs, and eliminating reliance on fossil-fuels for steam production.

Inlyte Energy’s core technology is a 2-in-1 long-duration energy storage battery made from naturally abundant and inexpensive raw materials — primarily, iron and sodium chloride (table salt). Their solution is suitable for commercial, industrial, residential, and utility-scale deployments, and specifically targets daily cycling applications with durations of 4-12 hours and 24+ hour resilience use cases.

Rondo Energy offers heat batteries that replace industrial, gas-fired boilers with low-cost, 24/7 zero-emission heat (1100-1500°C) and power from low-cost intermittent renewables and off-peak electricity. Each individual heat battery delivers megawatts of heat and can be used across heavy industry to eliminate reliance on fossil fuels and generate hot air or steam while lowering operational costs. Rondo's technology can be integrated into steam decarbonization strategies for utilities and district energy systems.
