Industrial electrification 2026: heat pumps for process, e-boilers, electric arc, plasma

Industrial electrification — replacing fossil fuel combustion with electric heating in industrial processes — gained momentum in 2025-2026. Industrial heat pumps reach process temperatures up to 200°C; e-boilers and resistance heating cover 250-1,000°C; electric arc furnaces serve very high temperatures. EU + US policy + carbon pricing driving adoption.

In 50 words: Industrial electrification — replacing fossil fuel combustion with electric heating in processes — gained momentum 2025-2026. Industrial heat pumps reach process temperatures up to 200°C; e-boilers and resistance heating cover 250-1,000°C; electric arc furnaces serve very high temperatures. EU + US policy + carbon pricing driving adoption.

The industrial heat problem

Industry accounts for ~30% of global energy consumption. Most industrial energy is heat — at various temperatures:

| Heat range | Industrial applications | |---|---| | Up to 100°C | Food processing, paper, low-temperature chemicals | | 100-200°C | Pharmaceuticals, mid-temperature chemicals | | 200-500°C | Petrochemicals, specialty chemicals | | 500-1,000°C | Glass, ceramics, mid-temp metals | | 1,000-1,500°C | Steel (DRI), cement, glass furnaces | | 1,500°C+ | Steel (blast furnace), specialty materials |

Most industrial heat is currently generated by burning natural gas, coal, oil. CO2-intensive. Industrial heat electrification is the alternative.

Technology options by temperature

Heat pumps (industrial)

  • Up to 100°C: mature commercial technology
  • 100-160°C: commercial scaling (Mayekawa, BITZER, MAN ES, GEA)
  • 160-200°C: emerging commercial (high-temperature heat pumps)
  • COP (Coefficient of Performance): 2.5-4.0 typical

Best for: food processing, dairy, breweries, pulp + paper, low-temperature chemicals

Electric boilers

  • Mature for low-temperature steam
  • Resistance + electrode boilers commercially available up to ~250°C
  • Higher capex but lower emissions than fossil boilers

Plasma + induction

  • Mid-to-high temperatures (300-1,500°C)
  • Industrial-grade plasma heating commercial
  • Induction heating very mature for specific processes

Electric arc furnaces

  • Standard for steel scrap melting (1,500°C)
  • Used for ~30% of global steel production
  • Limited by scrap availability

Hydrogen combustion

  • Long-term option for very high temperatures
  • Requires green hydrogen at industrial scale

Market activity

Commercial industrial heat pump deployments

  • Heineken: heat pumps replacing gas boilers at multiple breweries
  • Nestlé: heat pumps in dairy processing
  • Mars: heat pumps in chocolate manufacturing
  • AkzoNobel: industrial heat pumps in paint manufacturing
  • Multiple EU food + pharmaceutical players

Industrial e-boiler installations

  • Aurubis (copper smelter): large e-boiler deployment in Germany
  • BASF: process heat electrification investments
  • Multiple chemicals + paper companies

Steel electrification

  • Electric arc furnace expansion continuing
  • Green steel (H2-DRI) requires both electrification + green hydrogen
  • HYBRIT, H2 Green Steel, Tata Steel pilots all integrating

Policy drivers

EU

  • EU ETS pricing $70-90/tonne CO2 making electrification economic
  • ETS2 for industrial heat (specific) under discussion
  • Innovation Fund supporting first-of-kind electrification projects
  • Carbon Contracts for Difference subsidising green steel + green cement

US

  • IRA tax credits for industrial electrification
  • Bipartisan Infrastructure Law industrial decarbonisation funding
  • 45Q tax credit for CCUS (alternative to electrification for some industries)

Asia

  • Korea, Japan, China all with industrial electrification programs
  • Indian pilot programs at Tata, JSW emerging

Cost economics

For low-temperature heat (under 200°C), industrial heat pump economics:

  • Capex: 2-3x conventional gas boiler
  • Operating cost: 30-50% lower than gas boiler (when electricity priced lower than gas in $/kWh equivalents)
  • Carbon avoided: 200-400 kg CO2/MWh of heat (depending on grid mix)
  • Payback: 5-8 years typical without subsidies, 2-4 years with subsidies

For higher-temperature processes, economics more challenging.

What developers should know

For renewable energy + storage developers:

  • Industrial electrification creates significant new electricity demand
  • Industrial customers value continuous reliable power (BESS integration)
  • Long-term industrial PPA opportunities at premium pricing
  • Carbon footprint declarations make low-carbon electricity supply valuable

What to watch next

First commercial-scale 200°C+ industrial heat pump deployments (multiple expected 2026-2027) will validate that industrial electrification economics extend into petrochemicals + specialty chemicals. If successful, industrial heat decarbonisation accelerates meaningfully.
