etc.The Guardian view on hydrogen hype: it’s perhaps not as green as you think
Low carbon emissions in Europe cannot come at the cost of environmental destruction abroad
Tunisia is one of the driest countries in Africa, and has just suffered three years of drought. Yet the EU sees the country as key to producing “green hydrogen” for export to Europe. The trouble is, this fuel is obtained by splitting water into oxygen and hydrogen with electricity generated by renewable sources. Tunisia has lots of sun but precious little fresh water.
The only way of producing the raw material needed for green hydrogen is sucking up Mediterranean water and desalinating it. But a report last year for the Heinrich Böll Foundation, affiliated to Germany’s green political movement, warns that this would be a dirty, energy-intensive, water-guzzling process – and put the high cost of decarbonising the rich world on to the shoulders of poorer nations.
