40% of the world's water needs will go unmet by 2030 as desalination tech plateaus
Briefly

Water scarcity is a global challenge impacting 1 in 4 people worldwide, with 4 billion in water-scarce areas expected to rise to 5 billion by 2050. Breakthrough innovations are necessary to address this unprecedented crisis.
Desalination, the main source of new freshwater, faces challenges. Current technologies are unsustainable, largely dependent on fossil fuels, and facing diminishing innovation potentials since the early 2000s.
