On 26 August 2021, the Indo-German Chamber of Commerce (IGCC) in collaboration with the Indo-German Energy Forum Support Office (IGEF-SO) jointly organized a virtual knowledge session on “Transport of Green Hydrogen”. Ms. Sonia Prashar, Deputy Director General of the Indo-German Chamber of Commerce and Dr. Stephan Hesselmann, Economic Minister Counsellor, Embassy of Germany in India, inaugurated the session. Distinguished experts from Guidehouse, Hamburger Hafen und Logistik AG, EVOS Hamburg, Oiltanking Deutschland, Linde India and Fichtner Consulting presented various aspects of the transport and storage of green hydrogen.
Matthias Schimmel (Guidehouse) spoke about the long-distance transport of green hydrogen. He pointed out that energy should be transported in the form in which it is required by the demand side to avoid conversion losses. Repurposed pipelines tend to be the most effective hydrogen transport alternative, whereas ships are more suitable for derivates, such as ammonia and e-fuels. Ms. Karin Debacher (Hamburger Hafen und Logistik AG, HHLA) presented the ambitious strategy of the HHLA Group to become climate-neutral by 2040 by using hydrogen and fuel cell technology to decarbonize their operations, in particular heavy-duty vehicles. Mr. Joerg Bargest (EVOS Hamburg) elaborated on EVOS role as a storage provider and the potential role of hydrogen for the port of Hamburg. In particular, methanol, LOHC and ammonia storage are of interest here but for a working hydrogen supply chain many stakeholders need to be involved. Mr. Volker Wilms (Oiltanking Deutschland) stressed that it is already technically possible to have large-scale hydrogen storage capacities, but that costs and safety risks are the most important factors to take into consideration. For the storage of pure hydrogen, the costs for cooling and pressurizing infrastructure are relatively high and significant risks remain in comparison to its derivates, LOHC or e-fuels. Mr. Anish Paunwala (Linde India) talked about the last mile delivery of hydrogen. Inter alia, he emphasized that the delivery of hydrogen is a significant cost factor besides the often talked about production costs. Given a small distance of less than 500 km and small quantities of 5 tpd, gasified hydrogen is a very competitive mode of transportation, whereas a distance of more than 500 km and large quantities of 50 tpd or more, liquified hydrogen is often the cheaper option. LOHC is not competitive in both scenarios. Finally, Jonas Schneemeier (Fichtner Consulting) spoke on the necessary infrastructure to enable a green hydrogen economy. Taking the German gas network as an example, he pointed out that there are several possibilities to transition from natural gas to hydrogen, including blending of hydrogen into the existing network, converting pipelines and building new pipelines. The rededication of the gas infrastructure has to take demand and supply centres as well as storage infrastructure into account.
The presentations were followed by a lively discussion based on questions from the audience. Overall, more than 200 people participated.
