The government and its energy ministry are considering a solar-based hydrogen production initiative through major-scale photovoltaic facilities planned at state-controlled power utility PPC’s lignite fields in northern Greece’s Ptolemaida area, on the way out as a result of Greece’s decarbonization plan.
Discussions for solar-based hydrogen production are still at an early stage. However, if pursued, the initiative would be launched in the Ptolemaida area, until now a lignite-dependent local economy.
Major-scale photovoltaic facilities such as a 230-MW project being planned by PPC in Ptolemaida, as part of a wider 2-GW initiative for the region, are considered ideal for solar-based hydrogen production, requiring considerable amounts of energy.
Solar-based hydrogen production utilizes photovoltaic (PV) cells in combination with water electrolysis. The resulting hydrogen can be stored and used to reproduce electricity whenever needed by the grid.
Current electricity production costs linked to this technology are high. However, technological developments such as the mass production of electrolytes could lower power production costs and lead to economies of scale, making such an investment feasible.
Greece is already taking part in a European initiative looking to promote hydrogen production. Germany, preparing to take over the EU’s rotating presidency from Croatia in July, appears determined to push ahead with hydrogen production initiatives.
