Electrifying Industrial Heat in Petfood and Fishfeed Production
Geelen Counterflow developed an electric industrial dryer using heat pump technology to replace fossil gas burners in the production of pet kibble and fish feed. The technology utilizes a self-cleaning heat exchanger to recover waste heat and moisture. A 2022 installation at a Cargill-Ewos plant in Norway created the world's first zero-emissions fish feed factory, reducing energy use and running costs by 75% and eliminating 3,000 tons of annual CO2 emissions. The company has since expanded installations to China, South Korea, and Thailand, targeting markets where the 'spark ratio' between electricity and gas prices makes electrification financially viable.

Are electric heat pumps cheaper than gas furnaces?
The document argues that heat pumps are a cost-effective alternative to gas heating due to their superior energy efficiency, which allows them to overcome higher electricity costs. In the residential sector, heat pumps have outsold gas furnaces for four consecutive years. In the industrial sector, they are particularly viable for low-temperature processes (under 200°C), with the potential to increase U.S. GDP by over $42 billion by 2030. The briefing concludes that other alternatives, such as hydrogen and renewable natural gas, are less scalable and more expensive than heat pumps.

OVERCOMING ALL BARRIERS TO INDUSTRIAL ELECTRIFICATION
The report argues that direct electrification is the most efficient way to decarbonize industrial process heat, outperforming alternatives like green hydrogen, bioenergy, and carbon capture. It identifies three primary barriers: economics (high electricity costs relative to fossil fuels), grid readiness (slow interconnection and outdated planning), and technology maturity (lack of awareness and scale for high-temperature solutions). To overcome these, the authors recommend a combination of financial incentives (such as a Clean Heat Production Tax Credit), grid reforms (including surplus interconnection and real-time pricing), and foundational RD&D and workforce training.

Deploy Small Modular Nuclear Reactors
Small modular nuclear reactors (SMRs) are factory-built reactors with capacities under 300 MW that offer potential for flexible, low-carbon power and industrial heat. While the Nuclear Energy Agency projects a global market of 375 GW by 2050 that could avoid 15 Gt of cumulative CO2 emissions, SMRs remain in the demonstration phase. Significant barriers include high costs—estimated by Wood Mackenzie at US$6,000 to US$8,000 per kilowatt—which far exceed those of solar and wind power, as well as regulatory hurdles, waste disposal issues, and long deployment timelines that may limit their near-term impact on the energy transition.

A Production Tax Credit for Clean Industrial Heat
The policy brief outlines a framework for a production tax credit (PTC) to decarbonize industrial heat. It argues that the credit should target 'useful heat' used in manufacturing processes, be refundable to maximize investment efficiency, and utilize a rate based on heat temperature and power to account for varying technology costs. The author recommends excluding biomass and byproducts while focusing on scope 1 emissions to avoid complexity and ensure the policy targets industrial facilities rather than the electricity grid.

Direct electrification of industrial process heat
The study finds that direct electrification could replace 90% of the energy demand not yet electrified in European industry by 2035. While technologies like heat pumps and electric boilers are mature for low-temperature needs, high-temperature applications in sectors like cement and steel require further development of plasma, shock-wave, and resistance heating. The report highlights that economic barriers—specifically the price gap between electricity and natural gas—and organisational hurdles, such as insufficient grid infrastructure and long equipment lifetimes, are more significant obstacles than technical limitations. It argues that direct electrification is generally more energy-efficient than indirect electrification via hydrogen, particularly for low-temperature applications.

Industrial Thermal Batteries Decarbonizing U.S. Industry While Supporting a High-Renewables Grid
Industrial thermal batteries can convert electricity into high-temperature heat (1,500-1,700°C), potentially displacing 75% of U.S. industrial non-feedstock energy demand. The report analyzes two primary deployment modes: 'generation-following' (off-grid renewables) and 'price-hunting' (grid-connected, price-responsive). It finds that these batteries can provide heat at $35 to $62 per MWh, making them competitive with natural gas. The authors recommend financial incentives via the Inflation Reduction Act and reforms to electricity tariffs to reward the grid flexibility these batteries provide.

Nuclear Energy: Pathways and Requirements for Global Scale-Up, and the Role of U.S. Policy
The document asserts that nuclear energy is essential for a decarbonized global energy system to provide 'clean firm' power, reducing reliance on over-built variable renewables and expensive long-duration storage. It identifies a 'profoundly dysfunctional' current delivery model characterized by high costs and delays, exemplified by the Vogtle 3 and 4 projects in Georgia. To achieve a target build rate of hundreds of Gigawatts per year, the author proposes transitioning from bespoke construction projects to standardized, commoditized 'products' with capital costs below $4,000/kw and delivery times of 3-5 years. Key recommendations for U.S. policy include reforming the Nuclear Regulatory Commission (NRC) to adopt performance-based licensing, establishing a 'sandbox' for testing new designs, creating an International Bank for Nuclear Infrastructure, and ensuring the domestic availability of high assay low enriched uranium (HALEU).

Decarbonizing Low-Temperature Industrial Heat in the U.S.
Low-temperature industrial heat (up to 165C) accounts for approximately 35 percent of U.S. industrial process heat demand and produced 171 million metric tons of CO2 in 2021. Industrial heat pumps are identified as the most efficient and cost-effective zero-carbon solution for this range, outperforming alternatives like electrolytic hydrogen, bioenergy, and carbon capture and sequestration. Modeling suggests that a full transition to heat pumps by 2050 would reduce industry GHG emissions by 284 MMT (16 percent) relative to a business-as-usual case and prevent over 3,000 premature deaths by 2050. Economically, this shift could increase U.S. GDP by over $42 billion in 2030 and create 275,000 jobs in 2030. While heat pumps have higher capital costs than natural gas technologies, the gap is small and likely narrowing due to rising natural gas prices and falling electricity costs. The report recommends federal financial support via the DOE's AMMTO and IEDO offices, as well as the implementation of technology-neutral energy efficiency and GHG emission standards.
