The Role of Alkaline Electrolyzer in Market Adoption

The alkaline electrolyzer market held the dominant share of the green hydrogen market, due to its affordable and developed technology for producing hydrogen at scale. They are reliable and easily scalable, making them suitable for industrial and government-supported projects. This will motivate businesses to invest in hydrogen infrastructure and increase production.

On November 15, 2023, Asahi Kasei, Gentari Hydrogen Sdn Bhd, a wholly-owned subsidiary of PETRONAS clean energy arm Gentari Sdn Bhd (Gentari), and JGC Holdings Corporation (JGC) announced the completion of a detailed feasibility study for the production of up to 8,000 tonnes per year of green hydrogen using a 60 megawatt (MW) class alkaline water electrolyser system. The parties also signed a memorandum of understanding (MOU) for a front-end engineering design (FEED) study for the said project. This project is supported by the Green Innovation Fund for Large-scale Alkaline Water Electrolysis System Development and Green Chemical Plant Project by Japan’s New Energy and Industrial Technology Development Organization (NEDO).

Public-Private Partnerships as Growth Drivers

Southeast Asia is emerging as a hub for green hydrogen buildings, driven by public-private partnerships. The governments in the region are collaborating with major energy industry players and technology solution providers to accelerate the development, financing, and massive implementation of projects. The example of PTT partnerships with GIZ and thyssenkrupp Uhde in Thailand is illustrative of how PPPs can combine expertise, risk of investment, and economize on infrastructure. Therefore, these partnerships enable the production of goods on a large scale and also encourage research, innovation, and industrial adoption at a regional level.

For instance, on July 22, 2025, Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH, PTT plc and thyssenkrupp Uhde (Thailand) Ltd. joined forces under the International Hydrogen Ramp-Up Programme (H2Uppp) in signing a Cooperation Agreement (CA) for a new public-private partnership (PPP) entitled ‘Opportunity for green hydrogen and sustainable carbon-based products in Southern Thailand’ at PTT Head Office, Bangkok. This new project aims to expand markets and opportunities for green hydrogen and its derivatives in Thailand, focusing on strategic areas in the country’s southern region.

Government Policies and Incentives

The implementation of the green hydrogen vision in Southeast Asia is being achieved through government policies and incentives. Countries such as Malaysia, Indonesia, and Thailand already implement national hydrogen plans, providing tax reductions, subsidies, and favorable regulations to both local and foreign investors. These policy actions are rapidly intensifying the implementation of projects, promoting the development of research and development, and enhancing regional supply chains, establishing the principles of a successful and sustainable green hydrogen economy.
