At the request of the government of Japan under its G20 presidency, the International Energy Agency (IEA) has produced this landmark report to analyse the current state of play for hydrogen and to offer guidance on its future development.
Hydrogen and fuel cell technologies have experienced cycles of high expectations followed by impractical realities. This time around, however, falling renewable energy and fuel cell prices, stringent climate change requirements and the discrete involvement of China are step changes.
As Arctic shipping increases, pressure is mounting to protect the environment from fuels that are harmful when burned and spilled, including heavy fuel oil (HFO). Presently, the IMO is working to develop a ban on HFO in Arctic waters.
As the world strives to cut carbon emissions, electric power from renewables has emerged as a vital energy source. Yet transport and industry will still require combustible fuels for many purposes. Such needs could be met with hydrogen, which itself can be produced using renewable power.
