The publication of a national hydrogen strategy has been identified by the International Renewable Energy Agency (Irena) as the crucial first pillar in an evolving four-pillar policymaking toolbox for countries that are either planning to export or import green hydrogen as part of their multi-pronged decarbonisation efforts. In fact, Irena knowledge and policy specialist Emanuele Bianco argued during a webinar on Tuesday that such a strategy was required not only to define a country’s level of ambition for green hydrogen, but also to outline the amount of support required and provide a reference on hydrogen’s development for private investment and finance.
