However, without sufficient long duration energy storage to provide reliability for intermittent renewables such as wind and solar power, the success of the clean energy transition could be at risk. As the International Forum on Pumped Storage Hydropower highlights, pumped storage has an increasingly important role to play in the years ahead. Suzanne Pritchard reports

Crisis within a crisis On the opening day of the World Hydropower Congress 2021, the International Hydropower Association brought together two former prime ministers in conversation. Tony Blair and Malcolm Turnbull have both played pivotal roles in putting climate change high on the national and global political agenda. Here they discuss the role pumped storage has to play in the clean energy transition

Modernisation 18


Climate Change being described as a reality check, world leaders are being urged to face up to, and act now, on our changing climate. As part of its commitments, the hydropower industry has issued a new manifesto for change which outlines how sustainable hydropower investments can help achieve net zero emissions and limit climate change


Modernising Africa’s ageing hydropower fleet


The Africa Hydropower Modernisation Programme has been developed to enable and optimise the available hydropower capacity of existing plants and increase power systems flexibility, which is a requirement for the integration of more variable input from wind and solar resources. This in turn is expected to accelerate the transition towards clean, resilient and low-carbon energy systems across the African continent
