Products Overview
"Our Stance Isn’t Neutral.
Our Products Are."Source: ineratec.de
Ineratec's core technology involves utilizing green hydrogen (produced via electrolysis using renewable electricity) and combining it with CO2 captured from the atmosphere or industrial processes. This synthesis creates sustainable hydrocarbons, which can be refined into various products.
The company employs modular chemical reactors, which are compact and can be installed close to sources of renewable electricity and CO2. This allows for decentralized production, reducing transportation emissions and enabling local energy solutions.
Synthetic Fuels

Ineratec’s Power-to-X plants are modular systems that enable the production of synthetic fuels and chemicals. These plants integrate renewable energy and CO2, converting them into e-fuels and chemicals. Their modular design makes them scalable and adaptable for decentralized production, allowing for the installation of plants closer to renewable energy sources and reducing transportation emissions.
Applications
Aviation: Their e-kerosene serves as a sustainable alternative to conventional jet fuel, helping to reduce the aviation industry's carbon footprint.
Shipping: INERATEC's clean diesel can be used in maritime transport, offering ships a more environmentally friendly option.
Road Transport: The company produces CO2-neutral gasoline and clean diesel, which can be used in conventional vehicles as drop-in fuels.
Chemical Industry: INERATEC manufactures synthetic waxes and other chemical products that can replace fossil-based alternatives in various industrial processes.
Energy Storage: Their power-to-X technology allows for the storage of renewable energy in the form of liquid fuels, helping to manage fluctuating supplies of renewable electricity.
Decarbonization: INERATEC's e-fuels and e-products offer a viable option for hard-to-decarbonize industries that currently depend on fossil resources.
Long-distance Transportation: Their synthetic fuels are particularly suitable for sectors where direct electrification is challenging, such as long-distance shipping and aviation.
Modular Reactors Deep Dive
Ineratec’s modular reactors are central to their production of e-fuels and synthetic chemicals. These reactors are designed to convert renewable hydrogen and captured CO2 into hydrocarbons through the Fischer-Tropsch process. The reactors are compact and scalable, allowing for decentralized production, meaning they can be deployed close to renewable energy sources or CO2 capture sites, reducing transportation costs and emissions. The modularity ensures flexibility, enabling easy expansion of production as needed, whether for industrial-scale fuel production or smaller, localized projects.
Understanding the Modular Reactors
Microstructured Reactor Design
High Surface Area-to-Volume Ratio: Ineratec's reactors are microstructured, featuring channels on the microscale that significantly increase the surface area relative to the volume. This design enhances heat and mass transfer rates, leading to more efficient and controlled chemical reactions.
Efficient Heat Management: The small channels allow for rapid heat removal or addition, which is crucial for exothermic reactions like the Fischer-Tropsch synthesis. Effective thermal management prevents hotspots and degradation of catalysts, improving overall efficiency and lifespan.
Core Chemical Processes
Fischer-Tropsch Synthesis: The reactors facilitate the conversion of syngas—a mixture of hydrogen (H₂) and carbon monoxide (CO)—into long-chain hydrocarbons. The CO is derived from captured CO₂ through a reverse water-gas shift reaction.
Catalyst Optimization: The reactors use specialized catalysts that are finely tuned for optimal performance in microstructured environments. The catalysts promote selective reactions, increasing the yield and purity of the desired e-fuels.
Key Advantages
Decentralization: These reactors can be installed near renewable energy or CO2 sources, reducing transportation emissions and allowing for local, on-demand production.
Scalability: The modular design allows Ineratec to scale production up or down based on demand, making it more adaptable than traditional, large-scale refineries.
Flexibility: Their compact size and ease of integration make the reactors suitable for diverse applications, from industrial use to niche markets, and they are capable of producing various synthetic fuels and chemicals depending on need.
Partnerships
INERATEC has formed several key partnerships to enhance its production of sustainable e-fuels. One notable collaboration is with Sasol, where INERATEC secured a five-year contract for the supply of advanced Fischer-Tropsch catalysts. This partnership is aimed at improving e-fuel production efficiency. Additionally, INERATEC has maintained strong ties with the Karlsruhe Institute of Technology (KIT), as it originated as a spin-out from the institute, enabling a solid foundation for ongoing research and development efforts.
Another significant partnership is through the CARE-O-SENE Project, an international research consortium that includes Sasol, Helmholtz Centre Berlin, Fraunhofer Institute, KIT, and the University of Cape Town. This collaboration furthers the company's research into the production of sustainable aviation fuel (SAF).
Achievements
INERATEC has achieved numerous milestones in its journey toward producing sustainable fuels. The company was recognized as a Top Innovator by the World Economic Forum's UpLink platform in the Sustainable Aviation Challenge. Moreover, in 2021, INERATEC received €2.5 million from the European Innovation Council's Accelerator Program, which is intended to help the company scale its production capabilities.
Additionally, INERATEC has managed over 21 active projects with a cumulative production time exceeding 28,000 hours, serving more than 30 customers across diverse applications.
Case Study
INERATEC’s most ambitious project is the construction of its first large-scale industrial Power-to-Liquid plant in Frankfurt, Germany. Set to be the largest plant of its kind, it will produce up to 2,500 tons of synthetic e-fuels annually by converting 8,000 metric tons of CO₂. Construction began in 2023, with operations expected in 2024. The project represents an investment of over €30 million and is supported by the German Federal Ministry. It uses INERATEC’s modular power-to-X technology, combining CO₂ and green hydrogen to produce liquid hydrocarbons.

Funding and pricing
Ineratec's recent $129 million funding round, led by Piva Capital, is focused on scaling up their production of sustainable e-fuels. This funding will help the company expand its industrial-scale Power-to-X plants, which will boost output, reduce production costs, and potentially lower prices as volumes increase. This expansion is critical for making e-fuels a viable, cost-effective alternative for decarbonizing hard-to-abate sectors such as aviation, shipping, and heavy-duty transport. However, specific pricing details for their synthetic fuels or chemicals depend on factors like market demand, production capacity, and operational efficiency, which will evolve as their technology scales.
