Natural Gas And Italy's Transition To A Hydrogen Economy

Essay By Marco Brun | CEO & Chief Commercial Officer | AleAnna  

Italy is leveraging its existing natural gas infrastructure to accelerate its transition to a hydrogen economy, a critical component of its  decarbonization strategy. As one of Europe’s largest natural gas consumers, Italy recognizes the potential of blending hydrogen into  the energy mix to reduce greenhouse gas emissions and foster energy independence. Supported by European Union initiatives and  substantial domestic investments, Italy is setting the stage for a sustainable hydrogen-based future. 

The Role of Natural Gas in Hydrogen Production  

Currently, over 95% of hydrogen produced globally comes from natural gas through steam methane reforming (SMR). Italy's robust  natural gas infrastructure, including pipelines and storage facilities, makes it well-suited for large-scale hydrogen production and  distribution. In 2023, Italy consumed approximately 68 billion cubic meters (bcm) of natural gas, with plans to gradually replace a  portion of this with hydrogen to achieve its 2050 net-zero emissions goal. 

Italy's hydrogen production potential is substantial. According to the Italian Hydrogen Strategy, the country aims to produce5 million  tons of hydrogen annually by 2050. A significant portion of this hydrogen will be "blue hydrogen," produced from natural gas combined  with carbon capture and storage (CCS) technologies to minimize emissions. Pilot CCS projects, such as those in Emilia-Romagna, are  expected to sequester 1 million tons of CO₂ annually by 2030.

Leveraging Natural Gas Infrastructure for Hydrogen  

Italy’s extensive natural gas infrastructure, which includes over 33,000 kilometers of pipelines and 20 bcm of storage capacity, is being  adapted for hydrogen transportation and storage. The national gas operator, Snam, is at the forefront of these efforts. In 2022, Snam  successfully tested the blending of 10% hydrogen with natural gas in its pipeline network, demonstrating the feasibility of integrating  hydrogen into the existing system. 

By 2030, Italy plans to retrofit 70% of its natural gas pipelines to be hydrogen-ready, enabling the transport of up to 20% hydrogen  by volume. These upgrades will require an investment of approximately €2 billion but are expected to significantly reduce the costs  of building a new hydrogen-specific network. 

Hydrogen Applications in Italy  

The transition to a hydrogen economy will have wide-ranging applications across Italy’s industrial, transportation, and energy sectors.  Key initiatives include: 

• Industrial Decarbonization: Italy’s energy-intensive industries, such as steel and chemicals, are exploring hydrogen as a  replacement for coal and natural gas. For example, the Acciaierie d'Italia steel plant in Taranto has initiated a pilot project to use hydrogen in its production processes, which could reduce CO₂ emissions by up to 40%. 

• Transportation: Italy is expanding its hydrogen infrastructure to support fuel cell vehicles. By 2030, the country plans to build 300  hydrogen refueling stations, supported by €1 billion in investments. This network will initially serve heavy-duty vehicles, with the  potential to expand to rail and maritime transport. 

• Power Generation: Hydrogen-ready gas turbines are being deployed in Italy’s power plants to ensure a seamless transition from  natural gas. ENEL, Italy’s largest utility, is investing €3 billion in hydrogen-powered plants capable of running on 100% hydrogen by 2040. 

Economic and Environmental Benefits  

The transition to a hydrogen economy is expected to yield significant economic benefits. By 2050, Italy’s hydrogen industry could  contribute €10 billion annually to GDP and create 500,000 new jobs. Additionally, domestic hydrogen production will reduce  dependence on imported natural gas, enhancing energy security and insulating Italy from global price fluctuations. 

From an environmental perspective, replacing natural gas with hydrogen could eliminate 50 million tons of CO₂ emissions annually  by 2050. This shift aligns with Italy’s commitment to the European Union’s Fit for 55 targets, which aim to reduce emissions by 55%  by 2030. 

Challenges and Future Outlook  

Despite its potential, transitioning to a hydrogen economy faces challenges. High production costs for green hydrogen, estimated at  €5-6 per kilogram, remain a significant barrier. However, advancements in electrolysis technologies and scaling production are  expected to lower costs to €2 per kilogram by 2030. Additionally, retrofitting existing infrastructure and ensuring regulatory alignment  across sectors will require coordinated efforts. 

Italy’s commitment to hydrogen is supported by €3 billion in funding from the EU Recovery and Resilience Facility, aimed at  accelerating hydrogen infrastructure development and research. Collaborations with other European nations, such as Germany and  France, will further bolster Italy’s hydrogen ambitions, positioning it as a leader in the European hydrogen economy.

Conclusion  

Natural gas is playing a pivotal role in Italy’s transition to a hydrogen economy, providing the foundation for hydrogen production,  distribution, and integration. By leveraging its extensive natural gas infrastructure and investing in innovative technologies, Italy is  advancing toward a cleaner and more sustainable energy system. While challenges remain, the economic and environmental benefits  of a hydrogen-based future make this transition a vital part of Italy’s energy strategy. Through strategic planning and international  collaboration, Italy is poised to lead Europe’s hydrogen revolution.
