“The validation of our computational models at 100 MWh scale means that now we can go forward and build out other things, because we know that the whole product works.” — John O'Donnell, Rondo Energy Bianca Giacobone reports Rondo Energy has deployed its first full-size, 100 MWh industrial heat-battery system — an achievement that underscores the growing viability of thermal energy storage at scale. As industrial decarbonization gains momentum, solutions like Rondo’s thermal storage system are becoming critical pieces of the energy transition puzzle. https://lnkd.in/eqbK-fHA

What Rondo’s first full-size unit means for heat batteries -- Latitude Media "This fall, the thermal storage company Rondo Energy switched on a 100 megawatt-hour heat battery. It is its largest yet, and Rondo believes it to be the largest industrial heat battery in the world." This great story discusses how this project proved out Rondo’s designs, validated our models, and has set the stage for global expansion. "This readiness — both for operation and for infrastructure finance — is a milestone for the thermal storage technologies more broadly, which have the potential of displacing 'the equivalent of [roughly] 30% to 40% of current global gas use,' by 2050, according to a 2024 report by climate strategy firm Systemiq Ltd.. 'Once infrastructure finance got to solar PV, the market exploded, and we’re seeing that with other kinds of battery storage right now,' John O'Donnell said. “That’s our journey as well.'” Read more here via Bianca Giacobone: https://lnkd.in/eqbK-fHA

Tekniikka&Talous julkaisi tänään erinomaisen artikkelin Rondo Energyn maailman suurimmasta lämpöenergiavarastosta teollisuuden lämmöntuotantoon! Lämpöenergiavarasto mahdollistaa: - Täysin päästöttömän teollisuushöyryn / -lämmön - Perinteisiä teollisuushöyryn / -lämmön tuotantomuotoja edullisemman lämmön kustannuksen lataamalla akkua sähkön hinnan edullisten hetkien aikana - Ei muutoksia prosessiin. Lämpöakku korvaa perinteisen kattilan (kokonaan tai osan lämmöntuotannosta), 24/7 höyryn- / lämmön tuotanto - Soveltuu eri teollisuudenalojen vaihteleviin lämmön tarpeisiin ja höyryn olosuhteisiin - Erittäin korkea hyötysuhde - Ei harvinaisia metalleja, ei myrkyllisiä aineita.

🚀 Big milestone: The world’s largest industrial heat battery is now live in California. Amazing to think that when I first joined Rondo Energy, we were just deploying our first small-scale pilot project in the single-digit MWh range. Today, we’ve just brought a 100 MWh Rondo Heat Battery online, the largest industrial heat battery in the world, delivering zero-emission, high-pressure steam 24/7, powered entirely by off-grid solar in California. Replacing fossil fuel heat without any process changes - No facility redesign - No emissions - No rare minerals -- > Just clean steam 🌞💨 Proud to be part of the Rondo team, proving that industrial decarbonization is here, and it works. 👉 Learn more: https://lnkd.in/ebQpXsv3

🚀 Industry milestone! The world’s largest industrial heat battery is now RUNNING. At Rondo Energy, we just announced this unit: a 100 MWh Rondo Heat Battery, delivering steam 24-hours per day, powered entirely by solar. It has completed construction, commissioning and has been operating for >2 months and counting, fully meeting all customer contract specifications. Yesterday, Rondo was a company with a stellar concept, pilot in operation, and a number of announced projects in delivery. Today, we have proven the technology at full commercial scale. Headline is this is a solution for industrial plants to switch from gas to off-peak electricity, as a CHEAPER and zero-carbon, source of energy for their heat. The technology is a triple win: - Industrials can switch to cheaper energy for their heat, and decimate carbon emissions at the same time. - Rondo Heat Batteries add massive demand side flexibility to the power system. Exactly what the system needs to keep deploying renewables at pace. - A solution to advance electrification even in the face of congested grids, as flexible load uses existing networks when they are underutilized, during off-peak times. This also means better utilization of networks, so cheaper network fees for all network users. Industrial decarbonization is here. And it cuts cost. press release: https://lnkd.in/eCXSrhdK early coverage: https://lnkd.in/esJb6QmK

Announcement: Rondo Powers Up the World’s Largest Industrial Heat Battery! Our first 100 MWh Rondo Heat Battery is now online — delivering 24-hour industrial steam from off-grid solar, and setting a new benchmark as the world’s most efficient energy storage system. The daily operation of this unit has proven the heat battery's design, which boasts >97% round-trip efficiency and storage temperatures above 1000°C. This system proves a new path for industrial facilities around the world to cut carbon and control costs — turning intermittent solar energy into continuous, high-pressure heat. Built from brick and wire, the Rondo Heat Battery delivers the reliability that industry demands, with zero emissions, no scarce materials, and seamless integration into existing systems. This news marks a major milestone for industrial decarbonization — showing that heat batteries are proven at scale, now, and ready to deploy across global industry. https://lnkd.in/gWJ7-U5E

See Rondo featured in Atmos Magazine today: "This Brick Is the World’s Most Boring Climate Solution." Boring is not a bad thing. Especially when it means proven materials, robust supply chains and a drop-in fix without a factory-wide overhaul. And, not everyone thinks it’s boring, Eric Gimon with Energy Innovation said “After the rise of solar energy and lithium batteries, this is the third most exciting thing in my career that I have seen.” Read the story here: https://lnkd.in/gn_qZEfV
