The conference covered a wide range of topics that are crucial for the future of the hydrogen economy:

• Decarbonization of sectors that are difficult to reduce: There is enormous potential for hydrogen here, particularly in steel and cement production [source: 3].

• Renewable hydrogen production: The advances in electrolysis technology are impressive. More efficient and cost-effective electrolysers will revolutionize the production of green hydrogen [source: 3].

• Financing hydrogen projects: A critical point for scaling the technology. I was able to gain valuable insights into new financing models.

• Sustainable mobility and transportation: hydrogen fuel cell vehicles were a big topic. The possibility of powering buses, trucks and even the maritime and aviation sectors with hydrogen opens up enormous opportunities [source: 3].

• Alternative hydrogen carriers: Research into organic liquid hydrides or ammonia as more flexible and cost-effective transportation options for hydrogen is fascinating [source: 3].

• Standardization, certification and regulation: An often overlooked but crucial aspect for the global acceptance and trade of hydrogen.

• Global hydrogen supply chains: As an interim manager with a focus on China, this was particularly interesting for me. The development of international supply chains will be crucial for the success of the hydrogen economy.
