In a recent webinar by the India Smart Grid Forum, the challenges and economics of green hydrogen were discussed by Michael Barnard. The webinar highlighted the high cost of producing green hydrogen and the challenges associated with its transportation and storage. It was mentioned that hydrogen is not a cost-effective solution compared to other existing technologies for energy applications. The webinar also touched upon the inefficiency of using hydrogen for various purposes, including transportation, heating, and grid storage.
The discussion revolved around the struggles of green hydrogen production, specifically the high costs involved in the process. The webinar highlighted the significant investment required for green hydrogen projects and the limited success rate in bringing them to fruition. It was noted that many projects fail to secure buyers due to the extremely high cost of green hydrogen production through electrolysis. The session emphasized the need for a more realistic assessment of the economics and dynamics of green hydrogen in the energy sector.
Various challenges associated with the use of hydrogen in different sectors were addressed during the webinar. The safety concerns related to hydrogen use, especially in transportation and heating applications, were discussed. The presentation highlighted the complexities of storing and transporting hydrogen due to its low density and the expensive infrastructure required for handling the gas. The discussion also touched upon the viability of using hydrogen in maritime shipping and aviation, pointing out the uncertainties and high costs associated with these applications.
The webinar also delved into the issue of mixing hydrogen with natural gas in existing pipelines and the modifications required for such a transition. The session emphasized the difficulties and additional costs involved in using existing steel pipelines for hydrogen transportation. It was noted that hydrogen leakage and embrittlement of pipeline materials pose safety risks and require stringent modifications to ensure safe and efficient transport of hydrogen gas. Overall, the webinar provided a comprehensive overview of the challenges and limitations of using hydrogen as an energy carrier.
In conclusion, the presentation highlighted the need for a realistic assessment of the role of hydrogen in decarbonizing various sectors. While hydrogen has potential for decarbonization, the webinar emphasized the high costs, safety concerns, and technical challenges associated with its widespread use. The discussion underscored the importance of considering alternative technologies and solutions that may offer more cost-effective and efficient decarbonization options compared to hydrogen.
