To achieve carbon neutrality by 2050, hydrogen and ammonia are expected to become widespread as renewable energies, and the technology will begin to spread in society in 2030. In the midst of these social trends, we will introduce the forefront of technological development related to the production and utilization of hydrogen, ammonia and methylcyclohexane, which are being developed as energy carriers. For the first time in this session, we will hold an on-site networking event with the speakers after the lecture and look forward to your participation.
