The Japanese government plans to develop power generating technology that uses ammonia as a fuel.
This is part of efforts to reduce carbon emissions.
Ammonia does not emit carbon dioxide when burned.
The ministry of industry held its first international online conference on ammonia on Wednesday.
The meeting was attended by government and company officials from countries that produce natural gas, a raw material of ammonia.
The ministry plans to spend about 630 million dollars to develop the technology, while keeping toxic nitrogen oxygen emissions within environmental standards.
The ministry will team up with power companies and trading firms to establish a domestic supply chain for ammonia.
Ministry officials also plan to boost ties with natural gas producing countries to secure supplies of the fuel.
