Support frameworks which address both green hydrogen supply and demand, as well as cross-border initiatives, will be pivotal to delivering affordable green hydrogen, a panel has concluded. The ‘Gas & Hydrogen: Bridging the Gap’ panel, part of the ongoing Energy Storage Summit 2021 organised by Energy-Storage.news publisher Solar Media, brought together a panel of stakeholders of the green hydrogen economy, including advocacy groups, policymakers and project developers. Kicking off the debate was Peter Duffy of the Irish Energy Storage Association, who discussed the potential for green hydrogen to address the “real challenge” of providing energy storage for periods of time beyond 48 hours and as long as two to three weeks.
