Experts from India and Japan discussed possibilities of collaboration for the promotion of hydrogen-based technologies. They also explored related innovations, trends, concerns, and solutions at a webinar on De-carbonisation: Exploring the Hydrogen Prospects and Innovative Technologies.
The areas for India-Japan hydrogen research are cost reduction and improved performance for fuel cells, and hydrogen storage. Also, challenges for viable green hydrogen process routes, significant investments required for research infrastructure, and support for commercialisation, according to a press release.
Professor Kojima Yoshitsugu from the National Science Centre for Basic Research and Development, Hiroshima University, said that ammonia could be a potential hydrogen carrier because of its high hydrogen densities. “Direct combustion of ammonia is also possible without emission of carbon dioxide. The heat of combustion of ammonia is above 1.3 times of liquid hydrogen,” he added.
The webinar was jointly organised by the Embassy of India in Japan, the Indian Department of Science and Technology (DST), the Japanese Institute for Global Environmental Strategies (IGES), and the Indian Energy and Resources Institute (TERI). The event was held on 19 April and provided a platform for the experts to deliberate on the most recent innovations, trends, and concerns, and practical challenges and solutions.
Researchers also spoke about renewable hydrogen for disruptive decarbonisation. Hydrogen enables high efficiency and zero or near-zero-emissions operations. Green hydrogen will be good for industrial processes, chemicals producing, iron and steel, food, semiconductors, and refineries. The two sides will explore opportunities for co-innovation in accelerating green hydrogen to reduce dependency on petroleum imports.
The webinar also highlighted the IIT-Madras Research Park, which facilitates the promotion of research and development by the institute in partnership with industry, assisting in the growth of new ventures and promoting economic development. It also elaborated on the challenges in using fuel cells, like the non-existence of hydrogen fuel infrastructure and the difficulties related to hydrogen storage and transportation.
An expert from the Indian Institute of Science in Bangalore underlined the sustainable route of generating hydrogen using biomass, hydrogen from a range of sources, utilising, dispensing, storing, and distributing. It creates a level playing field for all sources of green hydrogen.
Hydrogen gas is a fuel with plenty of potentials. But because it is highly combustible, managing it safely is key. The advantages of a hydrogen energy system are that hydrogen gas is generated using a renewable energy source, instead of fossil fuels. It can be stored safely and is a clean, alternative power source, a Professor at the Institute for Materials Research, Tohoku University, explained.
The potential scale of hydrogen demand growth in India is significant. The costs of green hydrogen will start to compete with fossil fuel-derived hydrogen by 2030, at the latest. Hydrogen should be targeted at those sectors where direct electrification is not well-suited.
Representatives from the Institute of Energy Economics in Japan stressed the importance of green hydrogen and energy of system integration. The National Thermal Power Corporation noted that green hydrogen shall play a very important role. Along with pilots, NTPC is pursuing efforts with various stakeholders to shift to green hydrogen, ammonia, methanol, and industries. Also, fertilisers, refining, and long-range heavy-duty transportation blending into gas grids and energy storage.
The experts agreed that hydrogen could be a good alternative because of its capability of producing lower emissions and less pollution and looked forward to collaborations between groups in India and Japan to that end.
