Belgian Hydrogen Pipeline System – Global Energy Monitor

As Europe accelerates its shift towards a renewable energy future, the development of a comprehensive hydrogen infrastructure has emerged as a crucial component in the continent’s decarbonization efforts. One such major initiative is the proposed Belgian Hydrogen Backbone, a visionary project that aims to establish a nationwide network of hydrogen pipelines across Belgium.

Hydrogen Production

The Belgian Hydrogen Backbone envisions a multi-faceted approach to hydrogen generation, drawing from a diverse array of sources to ensure a robust and sustainable supply.

Renewable Hydrogen: A significant portion of the pipeline system’s hydrogen will be derived from renewable energy sources, such as wind and solar power. ​ This green hydrogen production utilizes state-of-the-art electrolysis technology to split water molecules, yielding pure hydrogen without any associated carbon emissions.

Fossil-Fuel Derived Hydrogen: While reducing reliance on fossil fuels is a long-term priority, the project also incorporates hydrogen production from natural gas, with the critical addition of carbon capture and storage (CCS) technology. This ensures that the emissions generated during the process are sequestered, effectively mitigating the environmental impact.

Electrolysis-Based Hydrogen: Belgium’s abundant renewable energy resources, particularly offshore wind, provide an ideal foundation for large-scale electrolysis-based hydrogen production. By leveraging these clean energy sources, the pipeline system can further bolster its low-emission hydrogen supply.

Hydrogen Storage

The successful implementation of the Belgian Hydrogen Backbone requires a robust storage infrastructure to ensure a reliable and resilient energy system.

Underground Storage: One of the most promising storage solutions involves the utilization of salt caverns, a technology already in use in the United States and the United Kingdom. These underground facilities offer large-scale, high-pressure containment for hydrogen, providing a crucial buffer against fluctuations in supply and demand.

Compressed Hydrogen Storage: In addition to salt caverns, the project also explores the potential of above-ground compressed hydrogen storage tanks. These systems, while generally smaller in scale, can provide flexibility and agility in meeting regional or localized hydrogen demands.

Liquefied Hydrogen Storage: For long-distance transportation and international trade, the Belgian Hydrogen Backbone is evaluating the feasibility of liquefied hydrogen storage. By reducing the volume of hydrogen through liquefaction, the system can enhance the efficiency and cost-effectiveness of cross-border hydrogen movements.

Hydrogen Transportation

The backbone of the Belgian Hydrogen Backbone is, quite literally, its network of pipelines that will transport hydrogen across the country and beyond.

Pipeline Networks: The project involves a combination of newly constructed hydrogen pipelines and the repurposing of existing natural gas infrastructure. This multi-modal approach allows for the efficient and cost-effective integration of hydrogen transportation within the existing energy landscape.

Truck and Rail Transport: While pipelines remain the primary mode of hydrogen transportation, the project also incorporates the use of trucks and trains to supplement the network, particularly for smaller-scale or specialized applications.

Marine Shipping: For international trade and the exchange of hydrogen between European nations, the Belgian Hydrogen Backbone is exploring the potential of marine shipping, including the development of dedicated hydrogen carriers and bunkering facilities.

Hydrogen Utilization

The Belgian Hydrogen Backbone is designed to serve a diverse range of end-users, unlocking the versatility of hydrogen as a clean energy vector.

Industrial Applications: Hydrogen will play a crucial role in decarbonizing Belgium’s industrial sector, particularly in high-temperature processes, steel production, and the chemical industry, where alternative solutions are scarce.

Mobility and Transportation: The project aims to facilitate the widespread adoption of hydrogen-powered vehicles, including heavy-duty trucks, buses, and potentially even maritime vessels, contributing to improved air quality and enhanced energy security.

Power Generation: Hydrogen’s potential as a flexible energy storage medium can also be harnessed for grid balancing and the integration of variable renewable energy sources, such as wind and solar, into the electricity system.

Regulatory Framework

The success of the Belgian Hydrogen Backbone is underpinned by a robust regulatory framework that ensures safety, environmental sustainability, and cross-border harmonization.

European Union Policies: The project aligns with the European Union’s ambitious hydrogen strategy, which sets targets for the deployment of electrolysis capacity and the production of low-emission hydrogen. These policies provide a supportive policy environment for the initiative.

National Regulations: Belgium has developed a comprehensive regulatory framework to govern the production, storage, and transportation of hydrogen, including safety standards and environmental impact assessments.

Safety and Environmental Standards: The pipeline system adheres to stringent safety protocols and environmental regulations to minimize risks and ensure the sustainable operation of the hydrogen infrastructure.

Challenges and Opportunities

The Belgian Hydrogen Backbone faces a range of challenges, but also presents significant opportunities for the country and the broader European energy landscape.

Infrastructure Development: The scale and complexity of constructing a nationwide hydrogen pipeline network require substantial investment, coordination among stakeholders, and the development of specialized technical expertise. Overcoming these hurdles will be crucial for the project’s successful implementation.

Cost Competitiveness: Ensuring the cost-competitiveness of hydrogen compared to traditional fossil fuels remains a key challenge. Continued advancements in production technologies, economies of scale, and policy support will be essential to bridge the price gap and drive widespread hydrogen adoption.

Sector Coupling and Integration: The Belgian Hydrogen Backbone’s success hinges on its ability to seamlessly integrate with other energy sectors, such as electricity, transportation, and industrial processes. Fostering sector coupling and system-level optimization will be critical in unlocking the full potential of hydrogen as a decarbonization solution.

As Europe’s energy landscape evolves, the Belgian Hydrogen Backbone stands as a shining example of the continent’s commitment to a sustainable, resilient, and interconnected energy future. By harnessing the power of renewable energy, advanced storage, and innovative transportation, this project exemplifies the transformative potential of hydrogen in driving the region’s clean energy transition. The European Future Energy Forum will continue to monitor and report on the progress of this and other groundbreaking initiatives that are paving the way for a greener, more prosperous Europe.
