On June 14, the International Energy Agency released its first major report on fuel that calls for the use of hydrogen as a potentially emissions-free source of energy. According to the report, the cost of producing hydrogen from renewable energy could fall by 30% by 2030 and the fuel could reduce emissions in the transport, chemicals, and steel industries. The agency outlines several recommendations for producing hydrogen from renewable energy sources and spreading its use across economies.
