DNV GL conducts hydrogen-readiness study for Italian gas network

Società Gasdotti Italia (SGI) has commissioned DNV GL to discuss gradually changing Italy’s second-largest gas network from natural to renewable gases such as hydrogen.

DNV GL experts in Groningen (the Netherlands), Norway and Milan (Italy) will investigate the potential of hydrogen transportation options across 1800 km of SGI’s high pressure regional and national network. The study will guide SGI in identifying suitable sections of its gas network to safely convey blended mixtures of natural gas and hydrogen. The aim is to determine if and how 100% hydrogen can be safely carried across the network.

The SGI study is aligned with the Italian Integrated National Energy and Climate Plan (PNIEC) published in 2019. The plan foresees the injection of hydrogen into the network, helping to increase the sustainability of existing networks and to exploit the natural gas infrastructure. Moreover, the plan sees renewables playing an important role in the country’s decarbonisation goal to reach 30% by 2030.

Hydrogen will play a key role in decarbonising Europe’s gas industry and contributing to the EU’s targets for net-zero carbon emissions by 2050. DNV GL’s '2020 Energy Transition Outlook' forecasts significant growth in hydrogen demand in Europe over the next three decades. From almost no demand today, it will account for almost half of end-use gas demand in Europe by 2050.

Scaling hydrogen as an energy carrier can offer benefits to countries with natural gas distribution infrastructure and decarbonisation ambitions. Switching gas networks from natural gas to hydrogen can allow energy providers to continue using infrastructure and avoid the cost of having to build electric substitutes.

“Hydrogen is becoming an increasingly important lever in the oil and gas industry’s decarbonisation efforts. Through executing projects like this, we are demonstrating how the natural gas infrastructure in the UK, the Netherlands and now Italy can be repurposed to safely and effectively transport hydrogen,” said Liv Hovem, CEO at DNV GL.

“We are delighted to secure this project with SGI and support them on navigating the risks and opportunities of the energy transition, ultimately accelerating bringing decarbonised gas to their customer’s homes and businesses,” concluded Hovem.

“SGI is convinced that hydrogen will play a key role in delivering the European decarbonisation goals. However, the opportunity offered by a well-established gas transmission system to decarbonise hard to abate sectors, must be demonstrated. We see growing biomethane volumes in our network and will soon start injecting synthetic renewable gas. These initiatives will prove the role that renewable gases and the whole gas system can play in a new, sustainable energy value chain”, said Federico Frassi, SGI CEO.

“The study with DNV GL will help to consolidate SGI’s ongoing work to ship hydrogen through the Italian gas transmission system and thus contribute to the achievement of the goals set by Italy’s Energy & Climate Plan,” concluded Frassi.

DNV GL is working with gas network operators and industry consortiums in several European countries to assess the safety and feasibility of switching existing natural gas infrastructure to carry hydrogen. The UK Hy4Heat programme, which aims to establish whether it is technically possible, safe, and convenient to replace methane with hydrogen in residential and commercial areas, is one example. A project run by Dutch gas and power networks operator Stedin, demonstrating that zero-carbon hydrogen could help to decarbonise heating in a residential apartment block near Rotterdam, the Netherlands, is another example.
