Delta bets on hydrogen power and microgrids as AI drives up Taiwan’s electricity demand

As artificial intelligence (AI) pushes electricity demand to unprecedented levels, Taiwan’s Delta Electronics is advancing hydrogen-based power generation and microgrid technologies in a bid to address looming energy constraints while enhancing grid resilience.

AI's power hunger creates a new energy imperative

The rapid expansion of AI is transforming not only the technology sector but also the global energy landscape. For Taiwan, home to some of the world's leading semiconductor manufacturers and an increasingly attractive destination for AI infrastructure, the question is no longer whether electricity demand will rise, but how quickly.

According to Delta Electronics executives, the scale of future demand is staggering. Speaking at Computex 2026, Chris Lai (賴俊吉), Head of Global Sales & Marketing for Hydrogen Energy at Delta, noted that projected AI-related electricity consumption could outpace available green energy supplies by as much as 40%.

Using publicly announced projects from Delta’s clients such as Microsoft, Oracle, Meta, AWS, and Vantage as examples, Lai said planned new data centers alone would require roughly 30 gigawatts of power — equivalent to Taiwan's entire current electricity consumption.

Beyond hyperscale data centers, semiconductor fabrication plants, advanced packaging facilities, GPU production, and server manufacturing are all expected to place additional strain on power systems, Lai told TCN.

Against this backdrop, Delta is pursuing a strategy centered on hydrogen-powered generation and microgrids.

Bringing hydrogen fuel cell technology to Taiwan

One pillar of Delta's energy strategy is the development of Solid Oxide Fuel Cell (SOFC) technology, a form of fuel-cell-based power generation that converts fuel directly into electricity through electrochemical reactions rather than combustion.

Lai explained that SOFC systems offer several advantages particularly relevant to AI-era power demands. The technology can achieve high power efficiency, while additional heat recovery systems can further improve overall energy utilization.

Compared with many conventional power-generation methods, SOFCs also produce lower carbon emissions and generate significantly less noise, Lai said.

Lai told TCN that the initiative gained momentum in January 2024, when Delta signed a technology transfer agreement with British clean-energy company Ceres Power.

Lai added the agreement provides Delta with access to patents, trade secrets, and manufacturing know-how from a technology platform that has already undergone years of development.

Rather than starting from scratch, Lai said Delta intends to combine the imported technology with Taiwan's manufacturing ecosystem to provide more competitive solutions.

"We are bringing mature technology to Taiwan and leveraging the strengths of Taiwan's supply chain," Lai told TCN.

Lai stated that a pilot production line is currently being established in Tainan, a city in southern Taiwan, where engineers are refining manufacturing processes, product design, and quality-control procedures.

The facility in Tainan is expected to complete production by the third quarter of 2026 and begin limited-volume shipments shortly thereafter.

A larger-scale manufacturing facility in Taoyuan is planned for future mass production, according to Lai. He told TCN that Delta has already received interest from AI-related customers seeking alternative power solutions.

Lai noted that the potential market for Delta's hydrogen energy solutions extends well beyond AI data centers. Server manufacturers, GPU producers, semiconductor fabrication facilities, and other power-intensive industrial users are all facing rapidly rising electricity demands, making them natural candidates for alternative energy systems. 

He added that companies operating in the energy, natural gas, and utility sectors also represent potential customers.

Lai said that, beyond its existing collaborations with partners in Taiwan and the United Kingdom, Delta has been engaging with firms across continental Europe, with several initiatives currently under discussion and more concrete developments expected to emerge in the future.

Microgrids as a buffer against grid constraints

Alongside hydrogen power, Delta sees microgrids as an increasingly important tool for supporting AI infrastructure.

Sonia Hsu (許美玲), R&D Director of Delta's Microgrid Solution Business Unit, described microgrids as a response to several emerging challenges: electricity shortages, insufficient transmission capacity, renewable-energy intermittency, and the explosive growth of AI-driven power consumption.

She explained that at the moment, household electricity consumption is expected to further surge due to the presence of AI servers in homes. Future increases are also expected with the installation of GPUs, quantum computers, and supercomputers.

Historically, Taiwan has relied on a highly centralized electricity system. However, Hsu argued that future demand may become more geographically concentrated as AI data centers and semiconductor clusters emerge across different regions.

In such circumstances, microgrids can provide localized and digitally managed power systems capable of operating independently from the broader grid when necessary.

Hospitals have long used similar systems to maintain operations during major outages, Hsu noted. She said AI data centers, semiconductor parks, and other mission-critical facilities may increasingly adopt the same approach.

For operators, the advantages extend beyond reliability. Microgrids can help bridge lengthy grid-connection delays, improve business continuity, reduce downtime risks through layered backup systems, and provide site-specific power resources under direct operational control.

Combined with energy-storage systems, Hsu said microgrids can also stabilize voltage and frequency fluctuations — an increasingly important capability as renewable energy sources account for a larger share of electricity generation.

She added that microgrids also support net-zero goals, since they produce less carbon per kilowatt-hour of electricity generated.

A vision of distributed energy

Asked what percentage of Taiwan's total electricity generation should ideally be generated by hydrogen, Lai emphasized that the true matter extends beyond any single technology.

He told TCN that Taiwan's future energy system should become more diversified and decentralized, drawing on a broader mix of solar, wind, geothermal, hydroelectric, and potentially nuclear power. Such diversification, he said, would strengthen overall grid resilience by reducing dependence on individual generation or transmission nodes.

Lai said that distributed energy systems and microgrids could also lessen the need for large-scale transmission infrastructure, potentially mitigating the local opposition that often accompanies new substations, transmission lines, and other centralized grid facilities. He said that the “NIMBY effect” (not in my back yard) is still present around communities worldwide when it comes to transmission infrastructures.

As AI reshapes industrial power consumption, Delta's investments suggest that future competitiveness may depend as much on energy innovation as on computing power itself.

For Taiwan, where semiconductors and AI are increasingly intertwined with national economic strategy, hydrogen fuel cells and microgrids may represent not merely technological experiments, but potential building blocks of the next-generation energy system and energy resilience.
