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.

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.
