The Global Hydrogen Electrolyzer Market

08.08.2023 / Lukas Strohmeier
This article provides an overview of the global green hydrogen market inthe second quarter (Q2) of 2023, focusing on the electrolysis sector. Theanalysis is derived from the updated Delphi Green Hydrogen market intelligence dashboardand focuses on OEMs and startups, as well as strategic investors in theelectrolyzer manufacturing sector.  

The second quarter was driven by developments in Asia. Japanese majorsare strongly involved in the global development of the hydrogen sector. Korean SK group, which is already invested into the American electrolyzer & fuel cell OEMs Plug & Bloom energy, announced in May it would join a 4.5 bn. USD green hydrogen project in Newfoundland, Canada.  

After announcing a pilot project utilizing Toyota's new proton exchangemembrane PEM-EL, automotive supplier Denso announced the test of their proprietary SOEC at the end of June. This marks the entry of just another giant Japanese corporation into the electrolyzer Original Equipment Manufacturer (OEM) market. While India also shows some dynamic developments, the  accelerating global expansion of Chinese electrolyzer OEMs was the most important development within the global electrolyzer and green hydrogen market. The top 3 leading Chinese OEMS achieved bookings of several hundred MW during the course of the first half of 2023.

Chinese Players Going International

Chinese engineering, procurement, and construction (EPC) firms areplaying a significant role in the global green hydrogen market. These firms are known for their expertise in large-scale project development and construction.During Q2 2023, Chinese EPCs have been actively developing projects in Northern Africa and Brazil, indicating their expanding international reach. Chinese EPCs will most often opt for Chinese electrolyzers, as the cost level is significantly below those of western competitors, and the EPCs typically have existing long-term business relations with many Chinese companies that manufacture electrolyzers. Chinese electrolyzer OEMs companies have also expanded their presence inthe global green hydrogen market during Q2 2023.

Envision, a leading clean energy company, announced its colossal plans at the “World Hydrogen NorthAmerica” in Houston. Envision, plans to established a significant electrolyzer manufacturing capacity of 40 GW/y by 2030, and claims to offerturnkey-hydrogen & synfuel plants with proprietary technology.  Envision is known for its expertise in wind energy has a strong track record in developing renewable energy projects worldwide. The company's pursuit of gigafactory plans in Spain, even in theabsence of immediate funding, demonstrates their long-term commitment to thegreen hydrogen sector.

, a prominent solar technology company, has also made strides in the European market. Known for their expertise in high-efficiency solar modules,Longi has a strong presence in the global photovoltaic industry. The collaboration with a partner in Spain further strengthens their foothold in Europe and highlights their efforts to expand into the green hydrogenmarket. Sungrow, a Chinese solar technology company, is also establishing an European market development teamfor its electrolyzers.

Sungrow has established a research institute in Germany
, carrying out research on the interaction of PV inverter, windpower converter, battery energy storage and green hydrogen, and cooperatingwith local universities and academic institutions.

Weak Project Pipeline Beyond China

While Chinese companies continue todrive significant developments in the green hydrogen market, the global project pipeline outside of China experienced limited progress in Q2 2023. This highlights the need for increased efforts to stimulate project developmentand investment in regions beyond China. Collaboration and knowledge-sharing between countries and industry stakeholders are crucial to overcoming thesechallenges and accelerating the growth of the global green hydrogen market.

Early indications from Q3 show, that some large orders were announced globally,prior to an expected summer break. The global dynamic in electrolyzer projectawards is clearly accelerating since June. The American IRA is not yet impactingthe  global electrolyzer project awards. Due to long project development timelines, some major FIDs & project awardsmight be announced towards the end of the year, although major market impactsare not expected prior to 2024.  

Developments in India, new market entrants and competitors offset Adani Scandal

India has shown significant interest and activity in the green hydrogen sector during Q2 2023. While Adani, a major conglomerate, will not make substantial investments in the green hydrogen business until 2025/26, other companies have made notable progress. Adani group was heavily hit by fraud allegations of American short seller Hindenburg. As a result, some investment plans, including the green hydrogen business, have been put on hold.

Three new Indian electrolyzer OEMs have entered the market, namely Jakson Green, Avaada Group, and Newtrace. These companies are poised to contribute to the development of India's green hydrogen infrastructure, leveraging theirexpertise in electrolysis technology and renewable energy solutions.

On the 28th of June, Avaada Group, a leading integrated energy platform, has announced the successful closure of $1.3 billion funding round,marking a historic moment for the green energy industry in Asia and India's renewable energy sector. The funding will be used to bolster Avaada's green hydrogen, green methanol, green ammonia, solar manufacturing and renewable power generation ventures, as part of India's commitment to a sustainable future. While the majority of the funds will not be allocated to electrolyzermanufacturing, the setup of an electrolyzer manufacturing plant is one of the communicated goals for the group.

Ohmium: The company with headquarters in the US is a key player in the Indian green hydrogenmarket, has sustained strong momentum during Q2 2023. The company could raise 250 MUSD in a Series C fundraise and added some experienced professionals to its senior management team. Furthermore, Ohmium has announced robust market activities, particularly in India, reflecting their commitment to driving the adoption of green hydrogen technologies in the region. Ohmium's efforts align with India's ambitious renewable energy goals and the growing importance of green hydrogen in the country's energy transition.

McPhy's manufacturing agreement with L&T (a major Indian EPC) further highlights India's focus on green hydrogen. The partnership aims to establish a local manufacturing facility for McPhy's electrolyzers, supporting the growthof the green hydrogen ecosystem in India and fostering technological advancements in the country.

The second quarter for leading OECD OEMs

Several companies have emerged as leaders in the green hydrogen and electrolysis sector. Their activities during Q2 2023 demonstrate their commitment to innovation and market expansion:

Belgian industrial John Cockerill and Technip Energies formed a Joint Venture to offer turnkey green hydrogen projects, based solely on John Cockerill’s pressurized alkaline electrolyzers. Rely will be headquartered in Belgium and Technip will own the majority (60%) of the newly formed companies stock. Rely will offer end-to-end solutions, from pre-Final Investment Decision services including technical & financial advisory through to proprietary products, project execution and operation and maintenance.

John Cockerill also entered into a strategic partnership with ADNOC for electrolyzer manufacturing in the United Arab Emirates. The collaboration with ADNOC strengthens their position in the market and underscores their commitment to providing advanced electrolyzer solutions.

Plug, a vertically integrated green hydrogen company and  leading provider of hydrogen fuel cell & electrolyzer systems, has made significant market progress in Q2 2023. The company has achieved multiple sales of its containerized 5 MW electrolyzer solution, showcasing the growing demand for their technology. Additionally, Plug Power has announced plans to develop three green hydrogen projects in Finland, totaling 2.2 GW, further solidifying their position as a key player in the global green hydrogen market.
