Indonesia’s green hydrogen development continues with broader interests and participations, and the momentum was displayed at the Second H2Uppp Seminar “Advancing Indonesia’s Green Hydrogen Future: Global Collaborative Pathways” held on 6 November 2025 at the JW Marriott Hotel, Jakarta. The event gathered decision-makers from government, industry leaders, and research institutions, outlining concrete plans to turn Indonesia’s vast potential into a sustainable green hydrogen economy and Power-to-X (PtX) projects. The message was clear: collaboration between public and private sectors is paramount, it’s the backbone of Indonesia’s path toward large-scale green hydrogen production, exports, and investment partnerships.
Organized by the German-Indonesian Chamber of Industry and Commerce (EKONID) and GIZ Indonesia/ASEAN, the seminar is part of the H2Uppp program, an initiative funded by the German Federal Ministry for Economic Affairs and Energy (BMWE), which supports companies in identifying, preparing, and implementing projects for the production and use of green hydrogen.
Ms Olivia Noor, Head of Business Development at EKONID, and Ms Atiek Fadhilah, Advisor to the H2Uppp project at GIZ Indonesia/ASEAN, highlighting supports for more collaborative approach for implementation between public and private sectors, and capacity development for relevant actors.
Three experts shared insights from strategic infrastructure planning to cutting-edge solar technologies, highlight the importance of public and private sectors are converging to develop the Indonesia’s vast renewable energy potential.
Mr. Ricky Cahya Andrian, Vice President of Business Development at PT. PLN (Persero), opened with a compelling presentation about a strategic roadmap for transforming Indonesia into a regional hub for green hydrogen production and export. With a staggering 3,687 GW of renewable energy potential—mostly from solar, hydro, and geothermal—Indonesia has the natural resources to support large-scale hydrogen development.
Mr. Ricky Cahya Andrian emphasized PLN’s commitment to decarbonization, highlighting the company’s plan to build 21 GW of renewable energy plants by 2030 and establish 100 ktPa of green hydrogen production capacity. He also shared insights into PLN’s pilot projects, including hydrogen refuelling stations and co-firing initiatives in coal and diesel power plants. The presentation underscored Indonesia’s strategic position in the region, with growing demand from neighbouring countries like Japan, South Korea, and Singapore. By 2050, PLN estimates that the combined market demand across these nations could reach 168 million tonnes per year—an opportunity Indonesia is eager to seize.
Providing a complementary perspective, Ms. Stefanie Stemmer, Country Manager of Project Development Program at GIZ, presented findings from a detailed study on green hydrogen investment opportunities. Her analysis focused on identifying commercially viable projects within Indonesia’s industrial clusters—fertilizer, chemicals, steel, and oil refining—where hydrogen demand is already significant. The study explored both small-scale and large-scale electrolyzer deployments, with Bekasi highlighted as a promising pilot location due to its proximity to existing chemical and pharmaceutical industries.
Ms. Stefanie Stemmer emphasized that while green hydrogen production costs currently exceed those of grey hydrogen, strategic siting, integration with renewable energy sources, and economies of scale can significantly reduce costs. The techno-economic models presented showed green hydrogen costs ranging from USD 8.6 to 12.3 per kilogram, and green ammonia from USD 2.1 to 2.7 per kilogram. She stressed the need for blended financing solutions, regulatory clarity, and international cooperation to bridge the bankability gap and accelerate project deployment.
The first session of the seminar concluded with a forward-looking presentation by Mr. Wibawa Hendra Saputera Ph.D, Research Center for New and Renewable Energy at the Institute Technology Bandung (ITB) who introduced the audience to the frontier of solar-driven hydrogen production. His research focuses on photocatalysis—a process that uses sunlight and semiconductor materials to split water into hydrogen and oxygen. Mr. Wibawa Hendra Saputera explained that while current solar-to-hydrogen (STH) efficiencies remain modest, recent breakthroughs have pushed lab results to over 9%, bringing the technology closer to commercial viability.
He showcased ITB’s innovative photoreactor designs, including slurry, panel, and spiral illumination systems, and discussed integration with concentrated solar power (CSP) and PV-powered LED systems. He also introduced a web-based platform for techno-economic analysis, enabling researchers and investors to model real-world hydrogen production scenarios. His presentation highlighted the importance of interdisciplinary collaboration, with ITB partnering with global universities and industry leaders such as Sparc Hydrogen and Syzygy Plasmonic to advance the technology.
In the second session, Dr. Christian Schnitzer, Senior Business Manager, Evonik Operations GmbH joined virtually from Germany and introduced Evonik as a leading specialty chemicals company with deep expertise in advanced polymers and membrane technologies that support the transition toward a sustainable gas and hydrogen economy. He highlighted the company’s global presence, strong innovation track record, and portfolio of high-performance materials designed for energy efficiency and renewable applications.
The core of his presentation focused on the DURAION® anion exchange membrane (AEM), designed to enable cost-competitive water electrolysis. He presented performance data showing high ionic conductivity, chemical stability, and mechanical durability, demonstrating the membrane’s suitability for industrial-scale hydrogen production. He concluded by emphasizing that advancements in membrane materials are essential for accelerating green hydrogen deployment and reaffirmed Evonik’s commitment to supporting scalable, cost-effective solutions.
Also joining the second session virtually from Austria, Mr. Peter Eisenköck, Vice President of Global Sales & Services Green Hydrogen present ANDRITZ’s expanding role in the global Power-to-X sector. He provided an overview of the company’s four major business areas and its long-term strategy focused on decarbonization, digitalization, and service-driven growth, emphasizing how these pillars support large-scale renewable fuel and hydrogen deployment across multiple industries. He also outlined the company’s comprehensive Power-to-X offering, which covers green methanol, renewable fuels, and integrated hydrogen solutions aligned with emerging regulatory requirements.
Mr. Peter Eisenköck highlighted key reference projects, including a 100 MW green hydrogen plant for Salzgitter Flachstahl in Germany, designed to produce approximately 9,000 tons of hydrogen annually for low-carbon steelmaking. He also noted the establishment of ANDRITZ’s electrolyzer gigafactory in Erfurt, which provides up to 1 GW of annual production capacity. He concluded by stressing three priorities for successful hydrogen development: holistic system integration, strong collaboration across the value chain, and ANDRITZ’s proven capability to deliver complex projects globally.
The third session of the Second Seminar spotlighted international collaboration and public-private partnerships (PPPs) as critical drivers of innovation and scale in the global hydrogen economy. Held across three parallel rooms, each focused on a distinct theme:

The H2Uppp Seminar in Jakarta provided a full-day platform for cross-sector collaboration, highlighting how global partnerships, public-private initiatives, and technical innovation drive green hydrogen and PtX development. Through three thematic rooms, speakers showcased real-world projects—from ammonia exports and carbon market integration to hydrogen safety and off-grid solutions—underscoring global cooperation and Indonesia’s readiness to lead Southeast Asia’s green hydrogen ecosystem. Green hydrogen is central to the energy transition and climate protection. Through H2Uppp, the Federal Ministry for Economic Affairs and Energy (BMWE) supports the entrepreneurial drive and project development crucial to the global scaling of hydrogen markets. In doing so, the BMWE fosters investment and propels the global hydrogen economy. These projects also offer local economic benefits, generating jobs, tax revenue, and entrepreneurial growth through the production, use, and trade of green hydrogen and its derivatives. With this initiative, BMWE helps meet future green hydrogen demand in Germany and Europe, while enabling valuable technology transfer.
