The 6 GW Headline: A Closer Look
Germany's hydrogen industry has been touting a headline number: nearly 6 gigawatts (GW) of paid reservations on the country's emerging hydrogen core network. The figure, presented by FNB Gas, the association of transmission system operators, was meant to signal strong momentum for the hydrogen economy. But a deeper examination reveals that the number is less impressive than it appears, and the underlying commitments are weaker than typical pipeline contracts.
Unpacking the Numbers
The nearly 6 GW figure is a sum of different categories: roughly 2.7 GW of hydrogen entry reservations, about 2.3 GW of exit reservations, and approximately 0.5–0.6 GW of inter-cluster transport capacity. While these are standard categories for pipeline operators, adding them together does not measure actual hydrogen demand. Hydrogen injected at one point and withdrawn at another can be counted twice—once as entry and once as exit—inflating the apparent demand.
This means the headline number does not represent 6 GW of hydrogen that German companies have committed to produce, buy, or consume. Instead, it is a network-capacity accounting figure that makes the commercial commitment look larger than it is.
The Denominator Problem
When compared to the planned size of the Hydrogen Core Network, the reservations appear even smaller. The approved network is set to span about 9,040 kilometers, with an estimated cost of €18.9 billion. It is designed to provide approximately 101 GW of entry capacity and 87 GW of exit capacity by the early 2030s. Against these design figures, the peak reservations represent only about 3.3% of planned entry capacity and 2.6% of planned exit capacity.
It is unrealistic to expect a new infrastructure network to be fully subscribed years before completion. Germany is deliberately building hydrogen pipelines ahead of demand to solve the classic chicken-and-egg problem: customers won't commit without infrastructure, and infrastructure can't wait for mature customers before construction begins. However, the concern is that Germany is building infrastructure for a volume that may never materialize, based on faulty premises.
Weak Commitments
The reservations themselves are also much weaker than typical long-term pipeline-capacity contracts. For instance, ONTRAS, a German gas transmission operator, allows customers to reserve future hydrogen capacity before the infrastructure is ready, with the option to decide later whether to convert the reservation into a firm contract. This flexibility means that the reservations are not binding commitments to purchase hydrogen or capacity.
In contrast, standard pipeline contracts often require shippers to pay for capacity regardless of use, providing a strong revenue guarantee for the operator. The reservation model used in Germany's hydrogen network is more akin to a placeholder, which can be abandoned without significant penalty.
Implications for the Hydrogen Economy
The overstatement of demand could have several consequences. First, it may mislead policymakers and investors into believing that the hydrogen market is more mature than it actually is. This could lead to overinvestment in infrastructure that may not be utilized, wasting public and private funds. Second, it could undermine confidence in the hydrogen sector when the reality becomes apparent, potentially slowing down the energy transition.
However, it's also important to note that building infrastructure ahead of demand is a deliberate strategy to stimulate market development. The reservations, even if weak, provide some signal of future interest and help coordinate the construction of the network. The key is to ensure that the capacity is sized appropriately and that the commitments are strong enough to justify the investment.
Conclusion
Germany's 6 GW hydrogen reservation headline is a case of overselling. The figure is a sum of different capacity types that double-counts demand, and the commitments are not as firm as they appear. While the hydrogen core network is a necessary step for Germany's energy transition, stakeholders should be cautious about interpreting the reservation numbers as a strong market signal. A more realistic assessment is needed to align infrastructure investment with actual demand, ensuring that the hydrogen economy develops on a sustainable path.
