PUERTOLLANO: In Spain, the dream of an emissions-free future for heavy industry starts with a rugged Castilian hillside covered in solar panels, and ends with an ice-cold beer. When the beer will be available, and how much it will cost, depends on an intervening rollout of green hydrogen.
This Mediterranean nation wants to become the European leader in hydrogen produced exclusively from renewable energy. With plenty of sunshine and wind and wide-open countryside to host those power sources, Spain’s ambition is to export the gas to the rest of the continent.
Green hydrogen is created when renewable energy sources power an electrical current that runs through the water, separating its hydrogen and oxygen molecules through electrolysis.
