Government Expands Support for Offshore Wind, Perovskite and Hydrogen

The Ministry of Economy, Trade and Industry (METI) proposed at an expert meeting (Green Innovation Project Subcommittee of the Industrial Structure Council) to use a portion of the remaining balance of the Green Innovation (GI) Fund to expand support for offshore wind power generation, next-generation solar cells (perovskite solar cells), and hydrogen production projects.

A new theme ‘Technology Development and Demonstration for Severe Environments such as Deep Sea’ has been added to the ‘Cost Reduction of Offshore Power Generation’ project. The theme will consider the deployment of floating offshore wind generation in EEZs (Exclusive Economic Zones), with an eye on further expansion into Asian countries and other regions with diverse ocean characteristics – including ocean depth, seafloor topography, and oceanographic conditions. The market for floating offshore facilities is expected to expand in the future, and Japanese companies are aiming to have a competitive edge in technologies essential for low-cost mass production.

In addition, the theme ‘Expansion of Perovskite Solar Cells to be Demonstrated’ will be added to the ‘Development of Next Generation Solar Cells’ project. Tandem perovskite solar cells are expected to be in great demand in the future, and the government will support their development and mass production. The new theme was highly anticipated as some companies in Japan already have know-how and world-class technology in the area.

Hydrogen Electrolysis: Advancing Next-Generation Technology

In the ‘Hydrogen Production by Water Electrolysis Using Electricity Derived from Renewable Energies’ project, ‘Development and Demonstration of Next Generation Type Water Electrolyzer (SOEC = Solid Oxide Electrolysis Cell)’ will be added. Although the SOEC type is still in the research and development stage, it has high electrolysis efficiency because it operates in a high-temperature environment. This feature enables lowering costs in the long run, although current costs remain high.
