DTU

The project

The goal of the Indo-DK Alliance is to enhance the global impact of research and knowledge-based innovation in sustainable energy technologies by fostering collaboration and networking among Danish and Indian industry and academic partners.

Indo-DK alliance will meticulously bridge the gap between fundamental research and practical applications, ensuring that recent electrochemical materials discoveries by academia will be utilized in practical solutions in sustainable energy technologies by the industry, decreasing the time from discovery to application.

Conference

Advancing Batteries, Electrolysis and Power‑to‑X at DTU.
From September 1st-3rd 2025, DTU hosted a three‑day conference bringing together leading Danish and Indian experts from universities, public research institutes and industry to share the latest advances in batteries, electrolysis and power‑to‑X. Across eight themed sessions, speakers covered topics from scalable graphene materials and operando battery diagnostics to advanced alkaline/PEM electrolysis and routes to large‑scale SOEC commercialization. Delegates also joined lab tours to EMAT and Capex, a dedicated poster session for PhD-students from both Denmark and India to showcase their research, and a conference dinner, creating ample opportunities for networking and collaboration.

A strong Indo‑Danish line‑up.
The programme featured contributions from Danish academia through DTU Energy, DTU Physics and Aarhus University alongside industry partners such as Topsoe, Stiesdal Hydrogen, Danish Graphene and NitroVolt. From India, academic and public research excellence was represented by IIT Bombay, IIT Kanpur, IACS, JNCASR, CSIR‑CGCRI and ARCI, with industrial perspectives from CUMI, Epsilon Advanced Materials and DensePower. Together, the diversity of viewpoints and research competencies were able to highlight the full innovation chain—from fundamental materials discovery to scalable manufacturing and deployment. The conference was able to showcase the importance of collaboration across borders to complement each others competences to increase the possible research possibilities, helping to solve the problems the world is currently facing in the energy sector.

Indian Delegation Visit

Deep‑dive into Denmark’s green‑tech ecosystem.

On September 4th-5th, the Indian delegation embarked on a targeted study tour showcasing Denmark’s innovation pipeline from applied research to full‑scale deployment. The programme began at the Danish Technological Institute (DTI), showcasing the importance between research and industrial application, followed by site visits to NitroVolt and Dynelectro. Nitrovolt, as a DTU spinout, offered a close look at technology maturation pathways in ammonia production, with Dyneelctro showcasing how complex solid oxide electrolyzer research can be implemented as simple module solutions for industry application.

From cutting‑edge manufacturing to integrated energy hubs.
Day two featured a visit to Stiesdal, highlighting industrialisation and scale‑up of their standardized, pressurized alkaline electrolyzer and hydrogen block system, before concluding at GreenLab, an integrated green energy and industrial symbiosis hub that connects production, storage and end‑use, showing the importance of proper infrastructure to connect the different green technologies. The visits provided practical insight into how Danish partners bridge R&D, pilot operations and commercial implementation in collaboration with domestic and international stakeholders.
