Its proprietary carbonate fuel cell and solid oxide electrolyzer technologies are highly regarded; it is currently developing large-scale hydrogen production systems based on solid oxide electrolyzers, targeting customers including large manufacturing facilities and data centers.

Leveraging local manufacturing advantages, Taiwan's hydrogen energy industry revolves around three core pillars: traditional industry transformation, byproduct hydrogen utilization, and the extension of green electricity. This has led to the emergence of landmark enterprises possessing both technical strength and growth potential:

Chung-Hsin Electric (1513): As the heavy electrical equipment giant with the most comprehensive hydrogen energy layout in Taiwan stocks, its SOFC technology has achieved mass production and commercialization, with 8 of the world's top 10 telecom operators as its customers. It is concurrently planning gas and hydrogen co-firing power plants to seize early opportunities in the power generation decarbonization market.

Its SOFC technology has entered the mass production and commercialization stage, with 8 of the world's top 10 telecom operators becoming its fuel cell customers. The South African government has even offered subsidies to invite its investment.

As of April 2026, Chung-Hsin Electric's order backlog reached NT$43.1 billion, with visibility extending to 2028. The company aims for its hydrogen energy business group to break even and start turning a profit by the end of 2026.

China Steel (2002): Leveraging its massive steelmaking byproduct hydrogen resources, the company is conducting deep R&D into "hydrogen-based steelmaking" technology, making it a core play in Taiwan stocks with actual hydrogen production capacity to help the steel industry achieve net-zero emissions. Its actively developed "hydrogen-based steelmaking" technology is regarded as a key path for the steel industry to achieve net-zero emissions.

Delta Electronics (2308): As the global leader in power supplies, the company is actively entering the solid oxide fuel cell (SOFC) sector, with low-volume production expected by the end of 2026 and large-scale ramp-up in 2027. It is simultaneously developing its AI power supply business to meet the growth in computing power demand.

In terms of AI power, Delta Electronics' AI power revenue share has rapidly increased from 2-3% in 2023 to 20-30% in 2025, and is projected to rise by over 19% further in 2026. Currently, the market's latest target price has been revised upward to NT$2,440, with 2026 EPS expected to reach NT$35.07 (up 55.5% YoY).

Kaori (8996): As a core supplier of key SOFC thermal and liquid cooling components, the company is deeply aligned with US hydrogen leader Bloom Energy. It has invested NT$4.2 billion in capacity expansion to meet the dual demand of AI liquid cooling and fuel cells, benefiting from the global data center trend of "bring-your-own-power" (BYOP).

In Q1 2026, revenue reached a record high, with thermal products up 306% YoY and order visibility extending to 2028. The company has also poured NT$4.2 billion into plant expansion to meet the dual demands of AI liquid cooling and fuel cells. As the purest SOFC supply chain play in Taiwan stocks, Kaori directly benefits from the global data center "bring-your-own-power" wave.

Unimicron (3037): The IC substrate leader is crossing over into the hydrogen energy sector. Through a hydrogen fuel cell procurement project (3-year term) valued at over NT$4 billion, it has achieved a strategic extension from traditional PCB substrates to the new energy field. The company announced its board's approval of the hydrogen fuel cell procurement project, which is expected to be fully installed within a three-year period by 2026, with a total project investment exceeding NT$4 billion.

Hydrogen can serve as an environmentally friendly alternative and supplement to reduce fossil fuel consumption and emissions. It is a renewable, storable, and transportable clean energy source that can complement other renewables to achieve lower costs and higher efficiency.

Currently, countries worldwide are accelerating research into and application of hydrogen technology to unlock its greater potential. For instance, fuel cell vehicles and hydrogen refueling stations are undergoing widespread deployment and development.

The Global Hydrogen Development Trends and China's Hydrogen Development Plan released last year noted that hydrogen is already deemed an indispensable technology for achieving global net-zero emissions by 2050. Over the coming years, a growing consensus suggests that hydrogen will become a vital energy source, as its low cost and low-carbon, eco-friendly attributes can satisfy future energy demands.

According to forecasts by the Hydrogen Council, the output value of the global hydrogen market is projected to reach $320 billion by 2030, while continuing to expand its market share.

With the accelerating global energy transition, the hydrogen industry is embracing unprecedented growth opportunities. A batch of hydrogen-themed stocks with investment potential has emerged in both the U.S. and Taiwan stock markets, allowing investors to select suitable targets based on their risk preferences and investment objectives.

However, the hydrogen industry remains in its infancy, facing challenges such as technological immaturity, high costs, and underdeveloped infrastructure. Investing in hydrogen-themed stocks requires a thorough understanding of the risks and challenges involved, as well as a readiness for long-term commitment.
