Sarangi cited policy uncertainties in Europe, a major potential export destination, the International Maritime Organisation (IMO's) deferral of its green fuel mandate by a year, and delay in implementation of 'Renewable Energy Directive-3' of the European Union, as key reasons for the expected delay. "Some of the decisions by the industry have also been deferred. Not all companies will defer," Sarangi said on the sidelines of the International Conference on Green Hydrogen.
