The U.S. industrial sector has long been tethered to natural gas for its vast heat requirements, a dependency that leaves manufacturers exposed to volatile energy markets and mounting pressure to decarbonize. A new analysis from UC Berkeley now offers a concrete pathway forward, finding that commercially available renewables paired with energy storage could reliably meet up to one-third of the nation’s industrial heat demand. This is not a distant theoretical prospect but a near-term opportunity that could reshape how America’s factories and processing plants source their thermal energy.
The report, led by researcher Jose Dominguez, examines the technical potential for solar thermal, heat pumps, and battery storage to serve process heat across a range of industries, from food processing to chemicals. Crucially, the analysis focuses on low- and medium-temperature heat applications—typically below 200°C—which account for roughly a third of total industrial heat use. For these applications, existing technologies are already cost-competitive or near-competitive with natural gas, especially when factoring in the price volatility that has rattled industrial buyers in recent years. The findings suggest that electrification of industrial heat is no longer a niche concept but a scalable strategy for reducing both emissions and energy cost risk.
The implications for energy markets and industrial strategy are significant. Natural gas has long been the default fuel for U.S. manufacturing, prized for its relative cheapness and reliability. But the era of stable, low-cost gas is not guaranteed, as geopolitical disruptions and weather-driven demand spikes have repeatedly shown. By integrating renewables and storage into industrial heat supply chains, manufacturers can hedge against fuel price swings while making progress toward corporate sustainability targets. For utilities and grid operators, this shift also represents a new source of demand for clean electricity—and a challenge to ensure that grid infrastructure can support increased electrification at scale.
There are, of course, practical hurdles. Retrofitting existing industrial facilities for electric heat pumps or solar thermal collectors requires upfront capital and engineering redesign. Not all processes can easily transition, and high-temperature applications above 200°C remain a tougher nut to crack. But the UC Berkeley analysis underscores that a substantial slice of industrial heat demand is within reach today, without waiting for breakthrough technologies. Policymakers and industry leaders should take note: the tools to decarbonize a significant portion of industrial thermal energy are already on the shelf. The question is how quickly the sector will deploy them.
