Simplify's Take

What believers are saying

  • October 2025 California operation proved daily automated industrial use, not just pilot performance.
  • November 2025 HEINEKEN contract and January 2026 Covestro groundbreaking expand commercial backlog.
  • Samsung E&A and Aramco partnerships open Saudi carbon capture, hydrogen, and industrial heat projects.

What critics are saying

  • Rondo still depends on Breakthrough Energy Catalyst and EIB financing for flagship deployments.
  • Covestro’s Germany project targets end-2026 commissioning; any slip damages bankability and sales cycles.
  • Thermal batteries need massive manufacturing scale; SCG’s 90 GWh factory plan remains execution risk.

What makes Rondo Energy unique

  • Rondo’s 100 MWh heat battery achieved 97%+ efficiency and 1,000°C storage.
  • Rondo delivers heat-as-a-service, integrating with existing boilers without factory rebuilds.
  • Covestro, HEINEKEN, and Samsung E&A validate Rondo across chemicals, beverages, and carbon capture.

Ultra-Durable Batteries: Why Next-Gen Tech Will Last Decades, Not Just Years

Batteries Made To LastAs the world electrifies and switches to renewable energy, the need for more energy storage grows. This is in part driven by the switch to EVs, but also due to the intermittent nature of renewable production.This can be partially compensated by other low-carbon sources of energy, like hydropower or nuclear, or maybe geothermal energy in the future. Still, advocates for green energy would by far prefer to see low-cost solar (and wind) be the basis of our energy systems.This creates a demand for batteries with fundamentally different characteristics than for mobility.EVs need very energy-dense batteries that are light enough in weight and small enough in volume to be carried in the frame of a car. Durability is a concern, but as long as the battery can function for 10-15 years, this is likely in line with the durability of the rest of the car's components.In contrast, energy storage batteries are much less constrained by weight or volume. However, they are definitely constrained by cost, as they are essentially an additional cost to the production of green energy and the power grid.One way to reduce the cost of energy storage is to use less expensive material than lithium for building the battery. Many alternatives are being considered, as we previously discussed in “ The Future Of Energy Storage – Utility-Scale Batteries Tech ”: batteries using technologies like sodium-ion, iron-air, zinc, sea salt, polymers, sodium-sulfur, or even molten metals.Another key element in reducing the lifetime cost of a battery system is to have it last several decades

Rondo Energy Is Working On Ways To Decarbonize Process Heat

Sign up for daily news updates from CleanTechnica on email. Or follow us on Google NewsRondo Energy is commercializing systems that reduce the carbon footprint of industrial systems that rely on process heat, which can be anything from the heat needed to cook food to converting iron into steel. According to the US Department of Energy, industrial process heat is the use of thermal energy to produce, treat, or alter manufactured goods. It is the most significant source of energy use and greenhouse gas emissions in the industrial sector, accounting for about 50% of all onsite energy use and 30% of greenhouse gas emissions. Process heating systems are emissions-intensive because fossil fuel combustion provides 95% of industrial heat across the manufacturing sector.Process heating systems raise or maintain the temperature of materials involved in the manufacturing process, such as the melting of scrap in electric arc furnaces to make steel, separating components of crude oil in petroleum refining, drying paint in automobile manufacturing, or processing food for safe consumption. Application temperatures range from 80°C to pasteurize milk and cream to over 1000°C to make cement.Companies like Rondo Energy use renewable energy when it is abundant and therefore inexpensive to heat rocks, bricks, or molten metals to red hot temperatures

More Hotshots Pick Hot Bricks For Industrial Energy Storage

Sign up for daily news updates from CleanTechnica on email. Or follow us on Google NewsMuch attention has been turned to zeroing out greenhouse gas emissions in the the electric vehicle field, but that’s minor league stuff compared to the challenge of decarbonizing the heat and electricity that power industrial processes. New energy storage technology has been emerging as a big-league solution, and the US startup Rondo Energy is among the innovators offering it up.Solving The Industrial Energy Storage RiddleTo be clear, new energy storage platforms won’t knock lithium-ion batteries out of the ring, but they will crack open new opportunities to clean up industrial processes that have resisted decarbonization through other means.As of this writing, an old technology — pumped hydropower energy storage — still dominates the non-battery storage field, by a wide margin. However, pumped storage is limited to particular circumstances of elevation and water resources. Some innovative pumped hydro solutions are beginning to emerge, helping to expand the range of applications. Still, the ideal solution would be a scalable system that industrial facilities can install on site.The California startup Rondo Energy is among the innovators focusing on solid state thermal energy systems
