The Global Hydrogen & Renewable Energy Summit 2025, held on March 12–13, 2025 in Kochi, Kerala, brought together policymakers, industry leaders, technology providers, researchers, and energy experts to discuss emerging trends in renewable energy and hydrogen technologies. During the summit, Sunil Kothari, Senior Regional Director, Energy Exemplar, highlighted the growing role of advanced energy modelling and digital tools in supporting the successful deployment of green hydrogen projects.
Addressing delegates, Kothari emphasized that as countries and industries accelerate their decarbonisation efforts, green hydrogen is emerging as a critical component of future energy systems. However, achieving commercial viability and scalability will require sophisticated planning, data-driven decision-making, and integrated energy system analysis.
Data-Driven Planning Essential for Hydrogen Projects
Kothari noted that green hydrogen projects involve multiple interconnected components, including renewable power generation, electrolysers, storage infrastructure, transportation networks, and end-use applications. Managing these complexities requires advanced modelling tools capable of evaluating technical, economic, and operational variables simultaneously.

According to him, energy modelling platforms can help stakeholders assess project feasibility, optimise investments, and identify potential risks before implementation, enabling more informed decision-making across the project lifecycle.
Green Hydrogen’s Growing Role in the Energy Transition
Highlighting the importance of hydrogen in future energy systems, Kothari said green hydrogen can serve as a bridge between the electricity and industrial sectors by helping utilise surplus renewable energy and supporting decarbonisation in hard-to-abate industries.
He explained that hydrogen can also play a role in addressing some of the challenges associated with renewable energy intermittency by acting as a long-duration energy storage solution. This capability could enhance grid flexibility and contribute to more resilient energy systems.
Addressing Cost and Commercial Viability Challenges
While the long-term potential of green hydrogen is widely recognised, Kothari acknowledged that cost competitiveness remains one of the sector’s key challenges. Factors such as electrolyser costs, renewable energy prices, storage technologies, and transportation infrastructure continue to influence project economics.
He stressed the importance of continuous scenario analysis and technology assessment to understand how declining technology costs and market developments may impact future project viability. Such analysis can help investors and developers make strategic decisions while reducing uncertainty.
Integrated Energy Systems Key to Success
A major theme of the discussion was the need for integrated planning across the entire hydrogen value chain. Kothari highlighted the importance of connecting power generation, hydrogen production, storage, transportation, and end-use sectors to create economically viable and operationally efficient solutions.
Advanced modelling tools, he said, enable stakeholders to evaluate different pathways and identify optimal configurations that balance costs, performance, and sustainability objectives.
Supporting Long-Term Energy Planning
Kothari also highlighted the role of modelling in long-term energy planning. As governments and industries pursue ambitious renewable energy and hydrogen targets, planners need tools capable of assessing future demand patterns, infrastructure requirements, and investment priorities.
By simulating multiple scenarios and evaluating potential outcomes, energy modelling can support strategic planning decisions and help organisations adapt to changing market conditions and technological advancements.
Digital Innovation Driving the Energy Transition
The summit discussions underscored the growing importance of digital technologies in accelerating the global energy transition. Artificial intelligence, advanced analytics, and energy modelling platforms are increasingly being used to improve efficiency, optimise resource allocation, and support investment decisions.
