DETROIT, MICHIGAN - November 9, 2026 (NEWMEDIAWIRE) - When it comes to replacing fossil fuel boilers, the first question an industrial company often asks is how much it will save. BrenX Ltd. (NASDAQ: BRNX), the provider of thermal energy storage and integrated industrial energy solutions, now has preliminary data from a working industrial installation to help answer that.

With commissioning ongoing at Tempo Beverages, BrenX’s flagship industrial project, the company recently reported that preliminary operating data indicated potential customer energy cost savings of approximately $1.0 million annually if current performance is sustained. 

At Tempo Beverages in Israel, BrenX’s 32 MWh bGen™ thermal energy storage system is supplying steam at a cost the company says is about 40% below a modeled heavy fuel oil steam baseline, based on preliminary operating data the company reported on November 4, 2026. 

At that level, assuming current performance is sustained under comparable operating and energy-pricing conditions, BrenX estimates that Tempo could save approximately $1.0 million annually, or approximately $15 million over 15 years. For the five operating days from October 25 to 29, the company estimates net energy cost savings for Tempo were about $18,200, or about $3,640 per operating day. The annual estimate assumes 280 operating days a year and is net of annual maintenance costs.

The System Is Outperforming Its Base Case

BrenX said the cost savings follow strong production results. On October 15, BrenX reported that the Tempo system had reached approximately 85 tons of steam per operating day during commissioning, about 21% above the project’s base case of approximately 70 tons. BrenX is targeting full replacement of Tempo’s steam demand. According to the company, steam sales above the contracted minimum can generate revenue beyond the baseline in the project’s financial model. In mid-October, BrenX said it was nearing completion of commissioning at Tempo, which would position the project to move into commercial operation.

Savings Customers Can See In Real Time

BrenX also said it developed a digital platform that gives Tempo live access to the system’s steam output, electrical power, pressure and temperature, along with charging costs, energy savings and avoided carbon emissions. A built-in savings calculator lets users model results under different electricity tariffs. BrenX said that for a company introducing a new kind of industrial energy system, that transparency can help shorten the sales cycle. A plant manager or CFO evaluating bGen™ can see preliminary operating data indicating potential customer energy cost savings, which BrenX said could be an important differentiator as it pursues additional industrial customers in Israel and Europe.

Why Now

The timing of BrenX’s preliminary cost savings data works in its favor. In late October, the Dutch TTF benchmark for European natural gas rose above 100 euros per megawatt-hour, its highest level since 2022, according to Trading Economics. For European manufacturers that burn gas to produce steam, those prices flow directly into operating costs.

One way to counter that is through electrification. Nearly 40% of fossil-fuel-based low- and medium-temperature industrial heat could be electrified cost-effectively, according to a recent report from the International Energy Agency (IEA). The IEA pointed to thermal storage as an “increasingly promising” solution, with food processing and dairy among the industries best suited for electrification. 

From Technology Supplier To Energy Platform

Tempo is the first proof point in a broader strategy for BrenX, which rebranded from Brenmiller Energy in August. Since then, the company has expanded its focus to developing, owning, operating and optimizing energy assets that may combine local generation, electrical and thermal storage, grid connectivity and intelligent energy management. The company wants to own the full life cycle of each asset. It believes that demonstrating sustained customer savings could support broader adoption of its energy services model and the development of recurring revenue from industrial energy services.

Hungary is one place where its business is expanding. BrenX owns and is operating a 1.2 MWp solar facility in Kaposszekcső and has signed a definitive agreement to buy the adjacent land for its planned first integrated energy resource center. The center is designed to combine solar power, battery storage, bGen™ thermal storage and, where appropriate, modular data center infrastructure to serve industrial customers and data centers.

In Israel, construction is underway on a 12 MWh bGen™ system at Wolfson Medical Center in Holon, designed to replace the hospital’s fuel-oil boilers. Once operational, the system is expected to save the hospital approximately $1.5 million in annual energy costs, giving BrenX a second reference project in a very different operating environment.

In September, BrenX also signed a settlement with the European Investment Bank to eliminate approximately $4.8 million of debt.

What Comes Next

The next milestone for investors to watch is the completion of commissioning at Tempo and the start of commercial operations. After that, attention will turn to validating sustained operating performance and customer energy cost savings at Tempo, progress at Wolfson and new industrial customers in Europe, where it says high gas prices are making the economics of electrified heat easier to see.

BrenX now has a working industrial installation and preliminary operating data indicating approximately 40% lower steam energy costs compared to a modeled heavy fuel oil baseline. For investors, Tempo offers the clearest measure yet of what the bGen™ technology could deliver commercially, as the company works to validate sustained operating performance and customer savings.
