In March of last year we chatted for the first time about hydrogen. Since then it's been a year of strategies, roadmaps and reports - there seems to be a new one every week. The industry is awash with 'momentum'. But is this all talk, or has there been action on hydrogen since we last discussed it? Are we starting to see signs that hydrogen is set to take off in 2020 and if so, in which applications and market sectors?
