PRESS RELEASE

DEE DEVELOPMENT ENGINEERS LIMITED PARTNERS WITH INTERNATIONAL CLEAN-TECH PARTNER TO ACCELERATE GREEN HYDROGEN SOLUTIONS IN INDIA AND THAILAND

New Delhi, June, 2025 – DEE Development Engineers Limited (“DDEL”), India’s leading provider of specialized process piping solutions for the oil & gas, power, and process industries, has announced a strategic partnership with International Clean-Tech Partner , a globally recognized innovator in sustainable energy technologies. This collaboration marks DDEL’s strategic entry into the green hydrogen sector, with a focus on deploying modular hydrogen production systems across India and Thailand.

Under a newly signed Memorandum of Understanding (MoU) , the two companies will codevelop, bid for, and execute Green Hydrogen Production System Projects . The partnership will combine International Clean-Tech Partner’s global leadership in hydrogen — technologies—including Electrolysers, Separators , and Hydrogen Purification Systems with DDEL’s strength of manufacturing ultra-pure hydrogen purification systems with up to 99.9999 % purity, its project execution, marketing, and long-standing marquee customer base .

“This partnership is a pivotal moment in our clean energy journey,” said Mr. Krishan Lalit Bansal , Chairman & Managing Director, DEE Development Engineers Limited. “With International Clean-Tech Partner’s proven technologies and DDEL’s execution expertise, we are confident of unlocking meaningful progress in India and Thailand’s green hydrogen ambitions. Hydrogen is poised to become a cornerstone of global decarbonization, and we are proud to lead the way alongside such a capable and visionary partner.”

International Clean-Tech Partner brings a legacy of excellence in environmental and clean energy systems, with a global footprint spanning advanced hydrogen generation plants, flue gas cleaning systems, and ultra-low emission technologies. Its projects across multiple countries deliver high-efficiency, environmentally sustainable outcomes.

DDEL , meanwhile, has significantly strengthened its Green Energy Portfolio through the recent acquisition of a majority stake in M/s Molsieve Designs Limited , a company with over 22 years of experience in manufacturing Hydrogen Purification Systems with up to 99.9999 % purity . This acquisition adds substantial technical know-how and production capacity to DDEL’s integrated clean energy capabilities.

Key Highlights of the MoU:

• International Clean-Tech Partner will provide technical support for containerized and modular green hydrogen projects, supply core systems and subsystems, and collaborate on digital modelling, documentation, and co-branded outreach efforts.

• DDEL will be responsible for local marketing, tender participation, project execution, obtaining statutory clearances, and delivering long-term after-sales service and support in India and Thailand.

Brief advantages of collaboration

• This alliance positions the partnership to gain competitive advantage in a fast-growing sector where few players possess the combined global technology depth and local execution capability to scale hydrogen infrastructure effectively.

• Alignment with India’s National Green Hydrogen Mission:

The collaboration directly supports the Government of India’s vision “to make India the Global Hub for production, usage, and export of Green Hydrogen and its derivatives.” By advancing green hydrogen projects in India and beyond, DDEL is contributing to the country’s goal of achieving Aatmanirbharta (self-reliance) in clean energy, reducing dependence on fossil fuel imports, and driving significant decarbonisation of the economy .

The collaboration is well-aligned with India’s National Green Hydrogen Mission and Thailand’s renewable energy roadmap , and reinforces DDEL’s commitment to driving sustainable infrastructure and the global shift toward clean, renewable energy.

The Board of Directors believe this collaboration will unlock long-term shareholder value and establish DDEL as a key player in India’s clean energy landscape.
