Green Hydrogen Projects – Siemens Energy vs. Linde: Who’s Powering the Clean Energy Transition?
The global race to decarbonize has pushed green hydrogen into the spotlight, and two industrial giants—Siemens Energy and Linde—have taken center stage. Both companies are investing in advanced green hydrogen technologies, vying to lead this potentially trillion-dollar industry. But how do their strategies compare? Who’s making bigger moves in 2024? Let’s take a deeper look at the most recent developments shaping this energy showdown.
Why Green Hydrogen Is Stealing Headlines
Green hydrogen is hydrogen produced using renewable energy sources, such as wind or solar, through a process called electrolysis. Unlike grey hydrogen, which is made using fossil fuels, green hydrogen creates no carbon emissions, making it a potential game-changer for industries like transport, power generation, and heavy manufacturing.
The International Energy Agency (IEA) forecasts demand for hydrogen will surge sixfold by 2050. And with many countries investing billions into hydrogen roadmaps, the competition among energy firms is heating up. Siemens Energy and Linde are two of the most influential companies pushing green hydrogen into the mainstream.
Siemens Energy: Betting Big on Electrolysers
Siemens Energy is no stranger to the hydrogen world. Their flagship push comes through a joint venture with French industrial gas giant Air Liquide. The project? Building one of Europe’s largest electrolyser factories in Berlin. The plant will produce industrial-scale proton exchange membrane (PEM) electrolysers, capable of generating green hydrogen at unprecedented scales.
As of June 2024, Siemens has announced progress on its 1 GW per year green hydrogen electrolyser production, with aims to scale up to 3 GW by 2026. Their focus is on reducing the cost and size of electrolysers for widespread commercial use.
Recent highlights:
- The Berlin electrolyser gigafactory is expected to begin full operations by end of 2024.
- Partnership deals with Denmark’s Ørsted and Germany’s RWE to supply hydrogen for offshore wind projects.
- Siemens Energy Germany was recently awarded a government contract as part of the €4 billion “H2Global” initiative.
Their strategy aligns with building flexible, export-ready electrolysers. Not only are they trying to generate green hydrogen for Europe, but also planning solutions tailored for markets in Asia and the Middle East.
Linde: Targeting Industrial Hydrogen Scaling
Unlike Siemens, Linde’s strategy is more vertically integrated and application-oriented. They aren’t just investing in electrolysers—they’re embedding green hydrogen across the supply chain, from production to liquefaction to transport. With decades of experience handling industrial gases, Linde is better positioned to manage downstream delivery.
In 2023, Linde announced a major green hydrogen plant in Texas, powered by Plug Power’s 120 MW electrolyser technology. They’re also involved in the H2morrow steel project in Germany alongside Thyssenkrupp—aiming to decarbonize steelmaking, one of the hardest-to-abate sectors.
Key developments in 2024:
- New green hydrogen facility in Alabama to serve the aerospace and mobility sectors.
- Partnership with BP and Shell to supply clean hydrogen at industrial scale to Europe’s refining sector.
- Increased investments in hydrogen liquefaction and distribution infrastructure.
Their core strength? Operational depth. Linde already supplies grey and blue hydrogen globally, and their focus now is transitioning these infrastructure routes to support green hydrogen.
Side-by-Side: Strategy Breakdown
Let’s compare these two companies based on their current approaches and achievements in green hydrogen.
| Aspect | Siemens Energy | Linde |
|---|---|---|
| Primary Focus | Electrolyser manufacturing and renewable project integration | Hydrogen delivery, liquefaction, and industrial applications |
| 2024 Capacity | 1 GW electrolyser production, scaling to 3 GW by 2026 | Over 200 tons/day hydrogen liquefaction capacity globally |
| Innovation Areas | Modular PEM electrolysers, low-cost hydrogen generation | Hydrogen logistics, storage, and end-use infrastructure |
| Key Partners | Air Liquide, Ørsted, RWE | Plug Power, BP, Thyssenkrupp, Shell |
From the table above, it’s clear both firms are playing to their strengths. Siemens Energy is tackling the heart of hydrogen generation with cutting-edge electrolyser technology. Meanwhile, Linde is making sure this hydrogen can actually get where it needs to go and be used by industries.
Hydrogen Economics: Can Either Company Make It Affordable?
The cost of producing green hydrogen remains a top concern. Currently, it ranges from $4 to $6 per kg—roughly double the cost of grey hydrogen. To drive adoption, companies need to bring this cost below $2/kg.
Here’s where Siemens and Linde differ again in philosophy:
- Siemens Energy is focused on making electrolysers cheaper and more efficient. They are applying mass manufacturing to reduce part costs and using AI-driven energy optimization to reduce power waste.
- Linde is reducing costs by co-locating production facilities next to renewable hubs, eliminating expensive hydrogen transport miles. Their experience allows smarter logistics, yielding significant savings at scale.
If green hydrogen is to compete with fossil fuels in the long run, both approaches are needed. Siemens lowers generation costs, Linde cuts downstream expenses.
Broader Market Forces in 2024
The rise of green hydrogen isn’t happening in isolation. Several global policy initiatives and public support schemes are playing massive roles:
- Europe’s RePowerEU plan has earmarked €90 billion for hydrogen infrastructure.
- The U.S. Inflation Reduction Act offers tax credits of up to $3/kg for clean hydrogen producers.
- China has launched five national hydrogen hubs, with Linde operating in two of them.
Both Siemens and Linde are aligning closely with these frameworks. In fact, Siemens recently launched a dedicated project office in Washington, D.C., to manage U.S. federal contracts. Meanwhile, Linde is deepening ties with Saudi Arabia’s NEOM, where the world’s largest green hydrogen project is currently underway.
Challenges Ahead: Can They Scale Globally?
Despite optimism, several challenges stand in the way for both firms:
- Regulatory complexity: Varying definitions of green hydrogen across regions can stall rollout.
- Supply chain constraints: Materials like iridium and platinum used in electrolysers are limited.
- Customer skepticism: Industrial buyers still hesitate to overhaul fossil-based processes.
Mitigating these risks will require global cooperation. Siemens is pushing for standardized electrolyser certification across the EU. Linde is championing safe transport standards in corridors connecting hydrogen-rich regions like Australia to high-demand countries like Japan.
Which Company Has the Edge?
There’s no easy winner between Siemens Energy and Linde. Their approaches differ but complement the same goal. Siemens is building the machines. Linde is enabling the end-use.
However, Linde appears to have more revenue from commercial hydrogen today. According to their Q1 2024 earnings report (available on linde.com), hydrogen represented over 10% of the company’s industrial gases segment—an all-time high. Their recent US Department of Energy grant for an east-coast hydrogen pipeline adds more momentum.
Siemens, on the other hand, is playing the long game. Once their gigafactory kicks into full gear, they could become one of the largest electrolysis hardware exporters globally. For countries building energy independence post-Ukraine crisis, that’s an enticing pitch.
The Hydrogen Future: Collaboration Beats Competition
There’s a good reason why Siemens Energy and Linde aren’t always direct competitors. In fact, they often end up working together. Take the H2Mare project, for example—a German initiative combining offshore wind turbines (Siemens’ turf) and hydrogen infrastructure (Linde’s specialty).
This reflects a deeper reality: no single company will dominate green hydrogen. Success depends on layered partnerships across production, logistics, regulation, and infrastructure. Siemens and Linde are simply leading different legs of a critical journey toward clean energy.
As 2024 unfolds, expect more announcements, pilot projects, and possibly, larger joint ventures involving both firms. For investors and industry watchers, keeping an eye on their progress, regulatory fits, and international partnerships is crucial.
And for the rest of us? More green hydrogen on the grid means cleaner air, lower emissions, and a real shot at beating climate change. Whether you’re cheering for Siemens or backing Linde, it’s clear we’re heading in the right direction.
