Hydrogen’s Green Energy Promise: On Thin Ice

Hydrogen’s crossroads: Promise and Peril in the Energy Transition

Is hydrogen the fuel of the future, or just a pipe dream? The answer, it truly seems, is hanging in the balance, especially as we look at the contrasting fortunes of hydrogen projects in Germany. While some initiatives are forging ahead, others are hitting the brakes, revealing the complex and often unpredictable landscape of the green energy sector.

In Emden, East Frisia, two narratives are unfolding simultaneously. One involves ambitious plans for large-scale hydrogen production, while the other highlights the growing uncertainties that plague the market. This dichotomy underscores the challenges and opportunities that lie ahead as the world races towards a cleaner energy future.

The Promise of Green Hydrogen: Emden’s Ambitious Projects

Emden is emerging as a key hub for green hydrogen production in Germany. Green hydrogen, produced through electrolysis powered by renewable energy sources like wind and solar, is seen as a crucial component in decarbonizing various sectors, from transportation to heavy industry.

EWE’s Hydrogen Coast Project: A Step Forward

The EWE regional supplier is making meaningful strides in constructing one of Germany’s largest hydrogen production systems. The company’s “Hydrogen Coast” project,backed by federal and state funding,recently commissioned Neumann company to build a compressor for their 280-megawatt electrolyzer from Siemens Energy.This electrolyzer, slated to begin producing green hydrogen by 2027, will use electricity from renewable sources to split water into hydrogen and oxygen.

The compressor will play a vital role in preparing the hydrogen for distribution,compressing the gas so it can be fed into a gas pipeline and transported to various end-users. This infrastructure is essential for creating a viable hydrogen economy.

The Role of Electrolyzers in the Energy Transition

Electrolyzers are at the heart of green hydrogen production. These devices use electricity to split water (H2O) into its constituent elements: hydrogen (H2) and oxygen (O2). When powered by renewable energy, this process produces hydrogen without emitting greenhouse gases, making it a clean and sustainable energy carrier.

Hydrogen can then be used in a variety of applications, including:

• Fueling hydrogen-powered vehicles, such as cars, buses, and even airplanes.
• Providing a clean fuel source for chemical processes and steel production.
• Storing excess renewable energy for later use.

Did you know?

The U.S. Department of Energy is investing billions in regional clean hydrogen hubs across the country,aiming to accelerate the production,processing,delivery,storage,and end-use of clean hydrogen. this initiative mirrors the efforts in Germany and highlights the global push towards a hydrogen economy.

The Perils of Uncertainty: Statkraft’s Retreat

While EWE is moving forward with its hydrogen project,the Norwegian company Statkraft has decided to halt the progress of new green hydrogen projects,citing “growing uncertainty in the market.” This decision underscores the challenges and risks associated with investing in this nascent industry.

Statkraft’s Pilot Plant in Emden

Statkraft operates a ten-megawatt electrolyzer in Emden as a pilot plant. The company also had plans for a larger, 200-megawatt electrolyzer, which had secured public funding commitments of over 100 million euros. Tho, Statkraft deemed the project “not calculable enough” due to “further profitability expectations.”

The company is now exploring the possibility of selling its hydrogen projects to investors who are willing to take on the risk. This move highlights the financial challenges and uncertainties that can derail even promising green hydrogen initiatives.

The Impact of Market Uncertainty

Statkraft’s decision reflects a broader concern about the economic viability of green hydrogen projects.Several factors contribute to this uncertainty, including:

• High capital costs for electrolyzer technology.
• Fluctuating renewable energy prices.
• Lack of established hydrogen infrastructure.
• regulatory hurdles and policy uncertainties.

These challenges can make it difficult for companies to justify the significant investments required for green hydrogen production.

Expert Tip

For companies considering investing in green hydrogen, it’s crucial to conduct thorough feasibility studies, secure long-term contracts with offtakers, and engage with policymakers to advocate for supportive regulations and incentives.

The Need for Stable Framework Conditions

EWE’s response to Statkraft’s decision underscores the importance of creating a stable and predictable regulatory environment for green hydrogen projects. According to EWE, Statkraft’s decision “illustrates how challenging the current framework for investments in green hydrogen projects” is.

The Role of Government Support

The CEO of EWE, Stefan Dohler, emphasizes the need for the federal government to create stable conditions for the long-term hydrogen economy. this includes:

• Accelerating the expansion of renewable energy sources.
• Streamlining funding processes and reducing bureaucratic hurdles.
• Advocating for changes to EU regulations that hinder green hydrogen production.

Government support is crucial for de-risking green hydrogen projects and attracting private investment.

the EU’s Electricity Reference Criteria: A Barrier to Progress

One of the key regulatory challenges is the EU’s requirement that electrolyzers must source their electricity “at the same time and in the same place” as a wind or solar park to qualify for economic incentives. This requirement, known as additionality, is intended to ensure that green hydrogen production does not rely on fossil fuel-based electricity.

However, critics argue that this requirement is overly restrictive and makes green hydrogen production more expensive and inefficient. In regions like Emden, which has a high concentration of wind energy production, this requirement can lead to curtailment of renewable energy and underutilization of electrolyzers.

Dohler argues that this requirement is “not only inefficient but also economically questionable,” notably in regions with abundant renewable energy resources. He calls on the federal government to work with the EU to change its reference criteria and create a more flexible and pragmatic regulatory framework.

Speedy Fact

Curtailment refers to the reduction in output of renewable energy generators,typically due to grid congestion or oversupply. This wasted energy could be used to produce green hydrogen if regulations were more flexible.

Hydrogen Hubs in Northern Germany: Stade and Hamburg

Emden is not the only location in Northern Germany with ambitious hydrogen plans. Stade and Hamburg are also developing large-scale electrolyzer projects, aiming to become key hubs in the emerging hydrogen economy.

Stade: A Gradual Expansion to 500 Megawatts

In Stade, plans are underway to build a 100-megawatt electrolyzer, with the goal of gradually expanding its capacity to 500 megawatts by 2028. This project aims to supply green hydrogen to local industries and contribute to the decarbonization of the region’s economy.

Hamburg: Overcoming challenges at the moorburg Site

Hamburg is also planning a 100-megawatt electrolyzer, which is scheduled for completion in 2027. However, the project has faced challenges due to its location at the site of the former Moorburg coal power plant. The demolition of a boiler house at the site was delayed, raising concerns about the project’s timeline.

Despite these challenges, Hamburg remains committed to developing its hydrogen infrastructure and becoming a leading center for green hydrogen production and utilization.

The American Perspective: Lessons Learned and Future Directions

The challenges and opportunities facing hydrogen projects in Germany offer valuable lessons for the United States, which is also investing heavily in the development of a hydrogen economy. The U.S. Department of Energy’s Regional Clean Hydrogen Hubs initiative, funded by the Bipartisan Infrastructure Law, aims to establish a network of hydrogen production, processing, delivery, storage, and end-use facilities across the country.
