A Strategic 3,300 km Infrastructure to Transport Green Hydrogen from North Africa to Italy, Austria, and Germany

by Marco Arezio

Green hydrogen has emerged as one of the most promising solutions for the global energy transition, seen as a clean and sustainable alternative to traditional fossil fuels. The SoutH2 Corridor project—an ambitious initiative that involves the construction of a 3,300-kilometer pipeline—fits squarely within this vision, linking North Africa to Central Europe through Italy, Austria, and Germany. This project represents a milestone in Europe's decarbonization strategy and a significant example of international cooperation in the energy sector.

An International Collaborative Project

The SoutH2 Corridor is the result of collaboration between several countries and industrial players and represents a model of cooperation between Europe and North Africa in the development of strategic energy infrastructures. The project aims to harness North Africa’s exceptional natural resources to produce green hydrogen, which will then be transported to Europe to meet the growing demand for clean energy.

North Africa offers ideal climatic conditions for renewable energy production. Thanks to vast desert areas, abundant sunshine, and constant winds, North African countries can generate substantial amounts of solar and wind power. These renewable resources feed electrolysis plants that produce green hydrogen—a fuel that emits no carbon dioxide when used.

Green Hydrogen Production in North Africa

The production of green hydrogen in North Africa relies primarily on water electrolysis, a process that uses electricity to split water into hydrogen and oxygen. When powered by renewable sources such as solar and wind, electrolysis produces hydrogen without greenhouse gas emissions, making it one of the most sustainable options for energy production.

Electrolysis Plants Powered by Renewables

Electrolysis plants in North Africa are designed to run exclusively on renewable energy. The region's unique combination of high solar irradiation and consistent wind patterns allows for efficient and continuous operation. Advanced photovoltaic technologies are used to convert solar energy into electricity to power the electrolysers. Similarly, wind energy is harvested through strategically positioned turbine farms to optimize energy output.

This dual-source approach ensures a stable and continuous power supply for the electrolysis process, even under varying weather conditions. The ability to generate surplus energy during peak periods also enables hydrogen storage for times of lower energy production, ensuring a consistent flow of hydrogen available for export.

Technological Challenges and Innovative Solutions

One of the main challenges in large-scale green hydrogen production is the energy efficiency of electrolysis. While the technology is well established, its efficiency can vary based on operational conditions and the type of electrolyser used. Recent technological advances have led to more efficient and durable electrolysers, capable of operating at higher temperatures and pressures, thereby reducing operational costs and increasing energy yield.

Another critical issue is water supply, essential for the electrolysis process. In a desert context like North Africa, water is a precious resource and must be carefully managed to avoid waste. To address this, renewable-energy-powered desalination plants are used to convert seawater into freshwater suitable for electrolysis. This approach not only ensures a steady water supply but also minimizes environmental impact related to local water resource use.

Transport Systems to Bring Hydrogen to Europe

Once produced, green hydrogen must be transported from North Africa to Europe—a task requiring advanced infrastructure and meticulous planning.

The Pipeline: A Strategic Infrastructure

The SoutH2 Corridor pipeline will originate in North Africa, cross the Mediterranean Sea, and connect to Italy, continuing north through Austria to reach Germany. At approximately 3,300 kilometers in length, the pipeline will be dedicated exclusively to transporting hydrogen. A key feature of the project is its ability to move large volumes of hydrogen over long distances while minimizing energy loss.

Constructed with advanced materials resistant to corrosion and high pressure, the pipeline ensures long-term durability and safety. Along the route, compression stations will be installed to maintain optimal hydrogen pressure, enabling a steady and secure flow. These stations will be equipped with real-time monitoring technologies to detect anomalies and intervene swiftly to prevent incidents or losses.

Maritime Transport and Storage Hubs

In addition to the pipeline, maritime routes may be used to transport green hydrogen to Europe. In this case, hydrogen would be liquefied and loaded onto specialized ships bound for major European ports. Upon arrival, the hydrogen would be re-gasified and distributed through national transport networks. Although logistically more complex, this method offers greater flexibility and complements the pipeline, particularly for regions not directly connected to the network.

In Italy—a critical node in the project—strategic storage hubs will be built. These hubs will serve as collection and distribution centers for hydrogen, capable of storing large volumes before dispatch to end markets. The hubs will be fully integrated with national and international transport networks, facilitating supply-demand management based on market needs.

Economic and Environmental Impacts

The SoutH2 Corridor will have a profound economic and environmental impact. Economically, the construction of the pipeline and hydrogen production facilities is expected to generate significant investment, stimulate economic growth, and create jobs in both North Africa and Europe. The development of a green hydrogen value chain will also reduce Europe’s dependence on natural gas and other non-renewable energy sources.

Environmentally, green hydrogen offers a vital solution for reducing CO₂ emissions in hard-to-decarbonize sectors such as heavy industry and transport. The production and transport of green hydrogen via the SoutH2 Corridor will help Europe meet its climate goals under the Paris Agreement while promoting sustainable development in North Africa.

Conclusions

The SoutH2 Corridor is more than just an infrastructure project; it is a cornerstone of the global energy transition and decarbonization strategy. By enabling the production of green hydrogen in North Africa and its safe transport to Europe, this project has the potential to transform the energy landscape on both sides of the Mediterranean.

Its success will depend on overcoming numerous technical, economic, and political challenges. However, with strong political support and effective international cooperation, the project could make a significant contribution to global climate objectives and stimulate economic development and job creation across regions. The SoutH2 Corridor could ultimately become a model for future initiatives, promoting a vision of a cleaner, more secure, and more sustainable global energy future.
