Zero Industrial.

Somewhere in North America, a factory needs steam at three in the morning. It always has. For a century, the answer was a flame - gas, oil, or coal, fed into a boiler, burned, and vented. Zero Industrial has a different answer, and it does not involve fire. The steam still shows up at three in the morning. The combustion does not.

That is the whole pitch, and it is deceptively quiet. Zero Industrial is a development company, not a gadget vendor. It builds, finances, and operates thermal energy storage systems - think of an extremely well-insulated box that gets charged with cheap, clean electricity and gives that energy back later as high-temperature heat. The factory keeps its process. It just stops lighting things on fire to run it.

Heat is the part of climate nobody likes to talk about

Electric cars get the headlines. Solar panels get the rooftops. Industrial heat gets ignored, which is unfortunate, because it is enormous. Making cement, paper, food, chemicals, and ethanol requires staggering amounts of heat and steam, and most of it still comes from burning fossil fuels on-site. Industrial process heat accounts for roughly a fifth of global energy-related carbon emissions. It is one of the hardest things to decarbonize, partly because the equipment is expensive, partly because factory operators are - reasonably - allergic to risk.

Here is the irony Zero Industrial noticed. The grid increasingly produces more clean electricity than it can use. Wind farms get curtailed. Midday solar gets thrown away. At certain hours, clean power is nearly free. Meanwhile, a few miles down the road, a factory is paying real money to burn gas for heat. The mismatch is almost rude. One side has surplus clean electrons it cannot store; the other side needs energy it can only buy as flame.

Two people who had seen this movie before

Zero Industrial was founded in 2024 by Ted Kniesche and Jim McDermott. Kniesche, the CEO, spent around two decades in clean-energy development across business development, finance, and government affairs - the unglamorous trifecta that actually gets projects built. McDermott, the co-founder, has started or invested in more than thirty-five companies and co-founded Rusheen Capital Management. Neither is a first-timer. That matters here, because the hard part of decarbonizing heat was never the physics.

The bet they made is structural, not technical. Thermal storage technology already exists from a handful of OEMs. The bottleneck is that no factory wants to gamble its capital budget on an unfamiliar box of hot bricks. So Zero Industrial takes that gamble off the table. It selects the technology, designs the system, handles permitting, lines up the electricity, finances the whole thing, and runs it. The customer signs a contract and buys the output.

A battery that gives back heat, not power

The mechanism is simple enough to explain at a dinner table. When electricity is cheap or being wasted, the system charges - storing that energy as heat inside a thermal mass. When the factory needs steam or process heat, the system discharges, delivering it on demand. No combustion happens at the site. No smokestack. The criteria pollutants that come with burning fuel - the stuff that makes neighbors and regulators nervous - largely disappear.

Around that core, Zero Industrial runs a full, milestone-based development process: feasibility analysis, equipment selection, system design and engineering, permitting, electricity procurement, financing, construction oversight, and ongoing operations and maintenance. It is, in other words, the entire awkward middle of an infrastructure project - the part most startups would rather skip and most customers cannot do themselves.

Ten million dollars and a model investors recognize

In April 2025, Zero Industrial closed a $10 million Series A. The round was led by Evok Innovations, a clean-tech venture fund, with participation from Rusheen Capital Management - the firm McDermott co-founded. The money is aimed squarely at building a project pipeline, not a science experiment. That is a tell. Investors funded a developer that plans to deploy proven storage at scale, not one still trying to invent the storage itself.

The Heat-as-a-Service structure is what makes the whole thing investable. The customer commits to a long-term contract for clean heat or steam. Zero Industrial - often with third-party project finance - puts up the capital and earns it back over the contract life. Early sector traction shows up in the company's November 2025 membership in the Renewable Fuels Association, a natural fit: ethanol plants are heat-hungry and under pressure to cut their carbon score.

Partnering with industry to decarbonize heat

That is the company's own phrasing, and it is refreshingly free of grandeur. The mission is not to save the planet in a press release; it is to make the clean option the cheap, boring, obvious one for a plant manager who mostly wants the steam to keep coming. Decarbonization that depends on heroism does not scale. Decarbonization that shows up as a lower invoice and zero capital outlay might.

It is a small company - around twelve people - taking on one of the largest and most stubborn corners of the energy transition. The competition is real: other thermal-storage and heat-electrification players like Rondo Energy and Antora Energy are chasing the same problem, and the incumbent, a fossil-fired boiler that already works, is the hardest competitor of all. Zero Industrial's edge is not a better brick. It is a better deal.

The flame was never the point

Industry burned fuel for heat because, for a long time, there was no better way to get energy where and when it was needed. That is changing. Clean electricity is increasingly abundant and increasingly wasted. The missing piece was a way to catch it, hold it, and hand it back as heat - and a business model that let factories say yes without betting the budget. Zero Industrial is building both.

So go back to that factory at three in the morning. The steam rises off the line, same as it did a century ago. The schedule is unchanged, the process is unchanged, the deadline is met. The only thing missing is the fire - and the bill, and the emissions, that used to come with it. The flame, it turns out, was never the point. The heat was. Zero Industrial just figured out how to keep one without the other.
