Is Green Hydrogen Pipeline Infrastructure Ready? Billions at Risk

The world is pouring unprecedented billions into green hydrogen and ammonia production, hailing them as the inevitable future of decarbonization for heavy industry, shipping, and even AI infrastructure. Yet, I've observed a silent, colossal bottleneck emerging: the sheer inability to physically move these fuels from where they are produced to where they are desperately needed. I believe we're building the wells, but not the pipelines. This looming infrastructure crisis, in my assessment, threatens to strand massive investments and derail critical climate targets.

A Production Boom Without the Delivery System

My research shows optimism abounds in green fuel production. India's AM Green Kakinada Project, for example, is targeting an astounding 1.5 million tonnes per annum (MTPA) of green ammonia by 2026, backed by a $10 billion investment and 7.5 GW of dedicated solar and wind capacity. I also found Saudi Arabia's NEOM project aims for 1.2 MTPA of green ammonia by 2026 or 2027, integrating 4 GW of renewables. Globally, green and blue ammonia production is projected to reach 14 MTPA by 2030. This is a remarkable acceleration, with the IEA noting in its 2025 Global Hydrogen Review that low-emissions hydrogen production is on track to reach 1 Mt in 2025. However, I discovered this still accounts for less than 1% of total global hydrogen demand, and its uptake is being held back by a critical lack of supporting infrastructure.

I've learned that the physical infrastructure required to transport, store, and trade these emerging energy carriers is dangerously underdeveloped. While production capacity is scaling, I see a significant disconnect in the planning and execution of delivery systems. For instance, countries like Australia and Chile are positioning themselves as major exporters of green hydrogen and ammonia, leveraging abundant renewable resources. However, I question how these massive volumes will actually reach demand centers in Europe or Asia. My concern is that without robust, ready-to-use transport pathways, these ambitious production targets risk becoming stranded assets, with billions poured into facilities that simply cannot deliver their product to market.

The Technical and Economic Hurdles of Hydrogen Transport

In my investigation, I've found that transporting hydrogen presents unique technical challenges. Unlike natural gas, hydrogen molecules are much smaller and can lead to material embrittlement in existing steel pipelines, making them brittle and prone to cracking over time. This means that while repurposing existing natural gas pipelines might seem like a cost-effective solution, it often requires extensive modifications, including internal coatings or the use of specific high-grade steels, and even then, blending limits (typically up to 10-20% hydrogen by volume) are often imposed to maintain pipeline integrity. I've seen estimates suggesting that converting existing natural gas pipelines for 100% hydrogen transport can be very complex and costly, often requiring significant upgrades or even full replacement of compressor stations and certain pipeline sections.

Furthermore, hydrogen's low volumetric energy density means that transporting the same amount of energy as natural gas requires significantly larger volumes or much higher pressures, which in turn demands more robust and expensive infrastructure. For long-distance transport, liquefaction is an option, but I’ve learned this is an extremely energy-intensive process, consuming up to 30% of the energy content of the hydrogen itself and requiring cryogenic temperatures (-253°C). This significantly adds to the cost and complexity. Ammonia, while easier to transport as a liquid at -33°C or under pressure, still requires specialized vessels and terminals, which are not yet widely available at the scale needed for future demand. I've noted that the capital expenditure for new hydrogen pipelines can range from $1 million to $5 million per kilometer, depending on diameter and pressure, making large-scale new builds incredibly expensive.

Global Efforts and the Urgency of Cross-Border Networks

Despite these hurdles, I've observed that some regions are making strides, albeit slowly. The European Hydrogen Backbone (EHB) initiative is a prime example, proposing a dedicated hydrogen pipeline network of nearly 53,000 km by 2040, with approximately 60% consisting of repurposed natural gas pipelines. I found that by 2030, the EHB aims for an initial 28,000 km network. Countries like Germany and the Netherlands are actively planning and developing their national hydrogen grids, with projects like the AquaDuctus offshore pipeline aiming to transport green hydrogen from the North Sea to Germany by the early 2030s. I've also seen announcements in the United States regarding hydrogen hubs, which include provisions for localized pipeline infrastructure, but a comprehensive national network is still largely conceptual.

I believe the challenge extends beyond national borders. The global nature of green hydrogen and ammonia trade necessitates international cooperation for cross-border pipeline development and standardized regulatory frameworks. Without harmonized safety standards, certification processes, and clear trade agreements, even well-intentioned national projects risk operating in isolation. I've seen discussions around developing hydrogen corridors between continents, but these remain largely on paper, highlighting the immense coordination required. The current lack of a clear global strategy for hydrogen infrastructure development, in my opinion, puts billions of dollars of production investments at severe risk of becoming stranded assets.

What This Means For Investors/Entrepreneurs/Professionals

For investors, I see a clear bifurcation of risk and opportunity. While the initial euphoria around green hydrogen production has driven significant capital into electrolyzer manufacturing and renewable energy projects, I've identified the transport and storage segment as the next critical bottleneck, and thus, a nascent area for strategic investment. Companies specializing in pipeline materials resistant to hydrogen embrittlement, advanced compression technologies, cryogenic storage solutions, and ammonia cracking technologies will likely see increased demand. I believe entrepreneurs should focus on innovative solutions for small-scale, decentralized hydrogen delivery for industrial parks or local mobility, bridging the gap until larger networks materialize.

Professionals in engineering, regulatory affairs, and project management with expertise in gas infrastructure, materials science, and international energy policy will be in high demand. I also think the financial sector needs to develop new models for de-risking large-scale, cross-border infrastructure projects, potentially involving public-private partnerships and international development banks. I found that understanding the evolving regulatory landscape, particularly in the EU with its hydrogen package and in the US with its Inflation Reduction Act incentives, is paramount for navigating this complex space. My advice is to look beyond just production and seriously consider the entire value chain, especially the often-overlooked middle mile of transport.

Bottom Line

I am convinced that while the world is rapidly investing in green hydrogen and ammonia production, the absence of a commensurate, ready-to-deploy pipeline infrastructure poses an existential threat to these investments and our decarbonization goals. I believe the coming years are critical for accelerating the planning, financing, and construction of dedicated and repurposed transport networks, both nationally and internationally, to prevent a colossal stranding of assets and ensure the green energy transition can truly take flight.
