The Heat Pump Conversation Is Missing the Industrial Half

The public conversation about heat pumps is almost entirely about homes. Residential heat pump policy, residential heat pump subsidies, residential heat pump rollout targets. These are real and worthwhile. They are also a small fraction of the heat pump opportunity, and the much larger fraction is getting almost no public attention.

The larger opportunity is industrial process heat.

The scale of industrial heat

Industrial process heat accounts for roughly a quarter of global energy consumption. The substantial majority of that heat is produced by burning fossil fuels, usually natural gas, sometimes coal. The temperatures involved range from very low to extremely high, and the share that sits below 200 degrees Celsius is significant. Below 200 degrees, modern industrial heat pumps work today, with COPs that make the economics attractive at current electricity prices in most European markets and an increasing number of North American ones.

We are not talking about a niche. We are talking about a meaningful share of the heat used in food and beverage processing, pulp and paper, chemicals, pharmaceuticals, district heating, and large parts of manufacturing.

Why the conversation is residential

Residential heat pumps are easier to talk about. There are more buyers. The policy levers are familiar. The visual is compelling. The political coalition is easier to assemble.

Industrial heat pumps are harder to talk about. The customer base is small and technical. The policy levers are different and require coordination with industrial regulators. There is no consumer story.

But the tons are enormous, and the deployment is currently lagging the technology by a wide margin.

What is blocking industrial deployment

Four things, in roughly this order.

Electricity tariff structure. Industrial sites in many markets pay a tariff designed for steady high consumption, with no benefit for matching electrified heat demand to renewable supply. Until tariff structure rewards flexibility, the operating economics of an industrial heat pump are dragged down by the same fixed grid charges that distort the rest of industrial electrification.

Capital availability. Industrial customers will not allocate their own balance sheet to a decarbonization project that competes with their core capex. The capital has to come from infrastructure investors. Those investors are increasingly available, but only for project sizes above a threshold that excludes most single sites.

Integration risk. An industrial heat pump replaces a piece of equipment that is integrated into a much larger process. The integration work is expensive and unfamiliar to the typical industrial engineering team. The technology suppliers have, until recently, not done this integration work as part of their offer.

Permitting timelines. The permitting process for replacing an industrial energy source is often as long or longer than the technical install. This is purely an administrative blocker, and it can be fixed without any technology change.

What would move the needle

A serious industrial heat pump policy would address all four. Tariff redesign for industrial flexibility. A public capital aggregator that pools small project sizes into financeable portfolios. Support for full-service integration offers from technology suppliers. And a permitting fast track for replacement-of-fossil industrial heat assets.

None of this is glamorous. All of it is achievable. And it would, in my estimation, deliver more decarbonization tons per public dollar than several of the consumer programs currently absorbing political attention.

The industrial half of the heat pump conversation deserves more than it is getting. The tons are there. The technology is there. What is missing is policy that treats the industrial customer as seriously as the residential one.
