As Europe embarks on a crucial journey towards a sustainable industrial future, the direct electrification of industrial process heat emerges as a pivotal solution. With the European Union (EU) setting ambitious climate targets for the next policy cycle (2024–2029), the integration of renewable electricity stands at the forefront of efforts to reduce greenhouse gas emissions while simultaneously enhancing energy security.
Recent studies illustrate that by 2035, direct electrification has the potential to substantially replace fossil fuels used for industrial process heat, catalyzing a transformative shift in the industrial landscape.
The Role of Industrial Process Heat
Industrial process heat is integral to a wide range of sectors, from chemicals and steel to food and beverages. This heat is essential for various manufacturing processes, such as drying, curing, and melting, making it the largest energy consumption category in the industrial sector. The reliance on fossil fuels for generating this heat has significant implications for both the environment and energy sustainability.
The Need for Electrification
To meet the EU’s climate neutrality goals, the decarbonization of industrial heat is not just beneficial—it is imperative. Current statistics reveal that a staggering three-quarters of CO2 emissions in the industrial sector result from the combustion of fossil fuels for process heat. This alarming figure highlights the urgent need to transition towards cleaner energy sources.
Current State of Electrification Technologies
The shift towards direct electrification is gaining momentum across various industries as stakeholders recognize its potential benefits. This transition is characterized by the increasing availability and sophistication of electrification technologies that can meet the diverse heat requirements of industrial processes.

- Benefits: Electric steam crackers will enhance flexibility in energy sourcing, allowing for more efficient processes.
Potential Impact by 2035
Our research indicates that direct electrification technologies could fulfill as much as 90% of the energy demand in European industries that currently rely on fossil fuels by the year 2035. However, to achieve this goal, significant effort must be directed towards accelerating the adoption of these technologies across all temperature levels.
Barriers to Electrification
Despite the promising outlook for direct electrification, several barriers hinder its widespread adoption:
Economic Challenges
- High Initial Investment:
- Transitioning to electrification technologies often requires substantial upfront costs, which can deter companies from making the shift.
- Market Uncertainty:
- Fluctuating energy prices and the uncertain regulatory landscape can create hesitancy among industries considering electrification.
Organizational Barriers
- Lack of Expertise:
- Many organizations lack the necessary expertise and knowledge to implement electrification technologies effectively.
- Resistance to Change:
- Established practices and reliance on traditional fossil fuel-based processes can lead to organizational inertia, slowing down the adoption of new technologies.
Regulatory Challenges
- Inadequate Policy Frameworks:
- Existing policies may not sufficiently incentivize or support the transition to electrification technologies, limiting their market potential.
- Grid Integration Issues:
- Integrating large-scale electrification solutions into the existing electrical grid can present challenges, including capacity limitations and regulatory hurdles.
Strategic Recommendations for Electrification
To overcome these barriers and harness the full potential of direct electrification, a comprehensive EU action plan is essential. This plan should include the following key components:
1. Establishing an Industrial Alliance
Creating partnerships among various stakeholders—governments, industries, and research institutions—will facilitate the market introduction of electrification technologies.
- Objective: The alliance would focus on sharing best practices, pooling resources, and fostering innovation.
2. Setting Deployment Targets
Clear and achievable deployment targets will encourage investments and ensure the industry remains on track to meet electrification goals.
- Example: Establishing specific targets for reducing fossil fuel use in industrial processes by a certain year will provide a framework for accountability.
3. Funding Support for Projects
Funding schemes tailored to support direct electrification initiatives will incentivize industries to make the switch.
- Approach: Grants, low-interest loans, and tax incentives can alleviate the financial burden of transitioning to electrification technologies.
4. Integrating Electrification into Grid Planning
Regulators should prioritize the incorporation of electrification strategies into grid planning to facilitate smoother transitions.
- Actions: Streamlining the permitting process for electrification projects and enhancing grid access for industries will be crucial steps.
5. Promoting Research and Development
Investing in R&D will drive innovation in electrification technologies, making them more accessible and cost-effective for industries.
- Focus Areas: Research should explore new materials, efficiency improvements, and scalable solutions that can be implemented across various sectors.
Case Studies: Successful Electrification Initiatives
Below are some oustanding case studies:
1. The Steel Industry
In several European countries, steel manufacturers are already implementing electric arc furnaces as a primary means of production. For instance, a prominent steel company in Germany has successfully reduced its carbon emissions by over 30% by replacing traditional blast furnaces with electric arc technology.
This case demonstrates that electrification can lead to substantial environmental benefits while maintaining production efficiency.
2. The Chemical Sector
Leading chemical producers are adopting heat pumps to generate process heat for various applications. A major chemical company in the Netherlands reported significant energy savings and emissions reductions by integrating heat pump systems into its operations. This shift not only enhances sustainability but also leads to cost savings in the long run.
3. Food and Beverage Manufacturing
In the food industry, electrification technologies are being employed to improve energy efficiency. For example, a beverage manufacturer has adopted electric boilers to produce steam for its production processes, resulting in a marked decrease in fossil fuel consumption and greenhouse gas emissions.
