The future of energy: eFuels from sustainable and integrated processes
Table of contents
What are integrated processes?
Integrated processes combine the steps of energy generation and fuel production in one place, ensuring maximum efficiency. The direct linking of these processes not only minimizes energy loss, but also reduces dependence on electricity transmission grids.
One example is the direct use of offshore wind farms to produce eFuels on site. Here, the energy generated is no longer fed into the electricity grid at great expense, but used directly for the production of hydrogen and synthetic fuels. This link makes the entire value chain more efficient and environmentally friendly.
Energy generation and fuel production are intelligently combined.
Energy losses are minimized and transport routes reduced.
Resources are used more efficiently, independent of network infrastructures.
How do integrated processes work at eFuels?
Integrated processes comprise several steps that are perfectly coordinated. The waste heat and energy surpluses from one process step are used directly in the next, increasing efficiency and sustainability.
1. energy generation
Energy is generated from wind and solar power, often at locations with optimal conditions such as offshore wind farms or in desert regions.
2. hydrogen production
The energy generated is used to split water into hydrogen and oxygen.
Increased efficiency: The waste heat generated during electrolysis is used directly for processes such as CO2 capture.
3. CO2 capture
The required CO2 is extracted from the air.
Here too, the waste heat from the electrolysis of water is used to support the process.
4. synthesis to eFuels
In the next steps, hydrogen and CO2 are combined to produce liquid fuels such as methanol or gaseous methane.
By-products: Depending on the process, sustainable fuels such as eKerosene and a range of raw materials that are essential for the chemical industry are also produced.
Solar and wind energy are used efficiently.
The waste heat from each step supports the next.
By-products such as eKerosene expand the areas of application.
The advantages of integrated processes
Increased efficiency through process linking
Integrated processes significantly reduce energy losses. Waste heat and energy surpluses are incorporated directly into the subsequent steps, which increases efficiency and reduces production costs.
Environmental friendliness
Resource consumption is reduced through the intelligent use of renewable energies and the reduction of transportation routes. At the same time, integrated processes reduce emissions as fossil fuels are completely replaced.
Cost efficiency
- Reduced infrastructure costs: Offshore wind farms that produce eFuels directly on site are not dependent on a connection to electricity transmission grids. The renewable energy is converted directly into synthetic fuels, eliminating transmission losses. These fuels can be distributed using existing means of transportation, pipelines and filling station networks. Find out more about storing renewable energy with eFuels here!
- Savings through waste heat utilization: The waste heat generated in the production process is used for subsequent steps, which lowers energy requirements and reduces overall costs.
Efficient use of waste heat minimizes losses.
Production costs are reduced.
Resource consumption is reduced and emissions are minimized.
Examples from practice
The advantages of integrated processes are no longer theoretical. There are already impressive examples of their successful application around the world:
One example of the integration of wind energy and eFuels production is the “Haru Oni” project in Chile. This pilot project uses the excellent wind conditions in the province of Magallanes to produce climate-neutral fuel using green wind power. The plant produces eFuels by using wind energy to electrolyze water to produce hydrogen, which is then processed with CO2 to produce synthetic fuels. This project demonstrates how offshore wind energy can be used directly to produce eFuels without the need to connect to electricity transmission grids.

Another example of the integration of offshore wind energy and eFuels production is the German hydrogen flagship project Hâ‚‚Mare. This project, which is funded by the Federal Ministry of Education and Research, is researching the direct production of green hydrogen and its downstream products. The Hâ‚‚Mare project focuses primarily on the production of green hydrogen directly on the high seas, without a connection to electricity grids. However, a key objective is to make this hydrogen usable for downstream products such as synthetic fuels (eFuels).

eFuels - A step towards the future
Sustainable energy for every area
The eFuels produced through integrated processes offer a practical solution for mobility, industry and heat supply. They make it possible to use renewable energy everywhere in a storable and transportable form. eFuels are capable of storing enormous quantities of renewable energy in combination with very cost-effective and durable infrastructure – this allows the large fluctuations in the generation of renewable energy to be balanced out highly effectively.
A contribution to climate protection
With climate-friendly production and optimized use of resources, eFuels are a sustainable alternative to fossil fuels and support global climate targets.
eFuels make renewable energy flexible to use - anywhere and at any time.
eFuels actively contribute to climate protection by maximizing the use of renewable energies.
eFuels as part of the energy future!
Integrated processes make eFuels the key technology for a climate-friendly future. These innovative processes combine efficiency and sustainability and set new standards in energy supply
Frequently asked questions (FAQ) - eFuels and integrated processes
Integrated processes directly combine the steps of energy generation and fuel production. For example, electricity from renewable sources such as solar or wind power is converted into hydrogen on site, which is then synthesized with CO2 to produce eFuels. This minimizes energy losses, reduces transport routes and increases overall efficiency.
Integrated processes increase the efficiency of eFuels production by:
- Reduce energy losses: Waste heat from one process step is used directly in the next.
- Reduce costs: Local production eliminates the need for expensive electricity transmission grids.
- Promoting sustainability: Resources are used more efficiently and emissions are minimized.
Offshore wind farms and solar projects in sunny regions serve as energy sources that enable continuous eFuels production thanks to their high yields.
The waste heat from one process step, such as the electrolysis of water, is used in subsequent steps, e.g. to support CO2 capture. This reduces energy requirements and significantly lowers production costs.
eFuels can be transported and stored in existing pipelines, filling stations and storage systems. This eliminates the need to create new distribution networks, which saves time and money.
Remote locations such as offshore wind farms or desert regions often produce more renewable energy than can be used locally. Integrated processes make it possible to store this energy in the form of eFuels and make it usable worldwide.
