Dutch long-duration energy storage project targets sub-€50/kWh costs with innovative technologies
The SLDBatt project brings together TRL 7 battery technologies – including molten sodium‑salt, saltwater acid–base flow, and hydrogen–iron flow batteries – to deliver an innovative and cost-effective long-duration energy storage solution.
Floating PV could power up to 490,000 households in Hong Kong
Hong Kong has limited land, and researchers have checked how much of the city can be powered if most of its water reservoirs were to be fully or partially covered with floating PV systems. At best, full coverage can supply more than 15% of the city’s total demand, and more than 60% of the residential demand.
