Ambitious plans one of the world’s largest steel corporations, Nippon Steel, to switch to green steel production by 2050 are included in the business plan of this enterprise in 2021. Nippon Steel aims to accelerate the transition from legacy manufacturing to greener, cleaner electric arc furnaces. Over the year, Japanese steel industry accounts for 155 million tons of emissions, and Nippon Steel — 94 million tons of emissions. The implementation of plans for the transition to zero emissions is associated with the use of hydrogen. The deep philosophy of the Japanese nation based on a sense of indissoluble fusion with the outside world, combined with a high level of development of modern technologies, the competence of engineering and technical personnel, internal discipline, invaluable experience in the implementation of past grandiose industrial and technological projects and other creative features of Japan is the basis for achieving such ambitious goals. What should you pay attention to, what other arguments are there in Japan for the implementation of the goal of reducing greenhouse emissions? It is an endless supply of geothermal renewable energy. There are legislative restrictions on the development of reserves of geothermal energy and the construction of new power generation facilities based on it due to the environmental impact of some components of geothermal steam. The prospect of green hydrogen production may force a new look at restrictive legislation. Modern technologies make it possible to reduce unnecessary components of geothermal steam to acceptable levels. It is geothermal renewable energy that is capable of making a breakthrough in the production of green hydrogen based on the electrolysis of seawater in the near future.
