Readiness Assessment of Green Hydrogen in African Countries’ report by ISA and Denmark:

Direct electrification cannot solve the decarbonisation requirements of industries that still rely on fossil fuels like coal, oil, or natural gas as feedstocks to produce commodities like steel, fertilisers, refined gasoline, and diesel fuel. Hence, green hydrogen, produced through the electrolysis of water powered by renewable electricity sources like wind, solar, and geothermal, emerges as a suitable replacement for fossil fuel-based energy sources.

High-level Conference on New Technologies for Clean Energy Transition

The International Solar Alliance, in a global collaboration with the Ministry of New & Renewable Energy, the Government of India, the Asian Development Bank, and the International Solar Energy Society, also organised the third edition of the High-level Conference on New Technologies for Clean Energy Transition. This event took place on the sidelines of the Seventh Session of the ISA Assembly in New Delhi today, uniting stakeholders worldwide.

The conference’s overarching goal is to translate dialogue into action. Deep-dive sessions focusing on new-age solar technologies, emerging storage technologies, and unleashing solar's role in accelerating equitable economic, social, and environmental development formed the crux of the discussions.

In his opening remarks, Dr Ajay Mathur, Director General, ISA said, “Today’s Conference and discussions are very timely. In a week, the world leaders will convene in Azerbaijan under the aegis of COP29 with two guiding goals: agreed to transition away from fossil fuels, triple renewable power and double energy efficiency by 2030. Both of these goals can be built on the foundations of efficient and clean technologies, hence underlining the importance of today’s proceedings.”

Mr Pralhad Joshi, Hon’ble Minister, New and Renewable Energy, India & President of the ISA Assembly, in his inaugural address, noted, “As the President of the International Solar Alliance, I would like to acknowledge that today the world stands united like never before, combining the global efforts towards the energy transition. The significance of advancing solar technology cannot be overstated as we move towards the clean energy transition. With the challenges posed by climate change, our collective efforts to innovate and implement this sustainable solution are more important than ever.” He further added, “At the International Solar Alliance, we believe that together we can harness the power of the sun to drive the change and create a more sustainable future. I am happy that at a platform like this, important technological advancements are being deliberated. This conference has brought together policymakers, experts, industry leaders, highlighting our global awareness.

Mr Prashant Kumar Singh, Secretary, Ministry of New and Renewable Energy, Government of India stated, “Government of India (GoI) has committed to translating the ISA vision into action. GOI is actively supporting through financial and technical means to assist developing countries in expanding their solar power grids to meet their energy needs. Solar energy has had a visible impact on the Indian energy scenario during the last few years. In addition to large-scale solar power plants, solar energy-based decentralised and distributed applications have benefited millions of people in Indian villages by meeting their energy needs in an environmentally friendly manner. With the increased support of the Government of India policies and improved economics, the solar energy sector has become attractive from an investor's perspective.”

Ms Mio Oka, Country Director, India Resident Mission, Asian Development Bank, noted, “We must ensure that growth is green, and it's our ADB's responsibility to facilitate emerging economies' access to technologies and finance to attain green growth. The good news is that the cost of clean energy has rapidly declined, and the share of renewable energy has increased. The cost of solar PV has declined by over 80% in the last decade to about $0.05 per kilowatt hour.”

Ms Viktoria Martin, President, the International Solar Energy Society, leaving a lead for the discussions to follow during the day said, “And I think this is the send-off idea for your discussion today, to think integrated planning in technology, to think about the diverse mix of storage that is needed to connect, for example, electricity generation to the other types of energy services, heating and cooling and transport, that are needed in our green and clean energy systems.”

Mr Emil S. Lauritsen, Head of Strategic Sector Cooperation, Embassy of Denmark, New Delhi, sharing his insights on the report, said, “This report is the first project under the umbrella of the memorandum of understanding for the green hydrogen partnership, which the Embassy of Denmark has inked with the International Solar Alliance. The objective is to conduct a readiness assessment of the target countries: Egypt, Morocco, Namibia, and Egypt. The report focuses on three categories: country-specific parameters, financing requirements and possible financing methods. It also includes assessing risks and preparing plans to develop a green hydrogen economy in these countries. Under the partnership, the Ministry of Foreign Affairs of Denmark will also support ISA with three years of content, focusing on green hydrogen policy, regulation, and other components of the green hydrogen value chain.”

Green hydrogen provides a great avenue to monetise a country’s rich renewable resources (wherever available), aid the country in achieving industry decarbonisation, and generate sustainable jobs in the process. Countries have been identified based on their vast renewable energy potential and thus can potentially contribute significantly to developing the green hydrogen ecosystem.
