…home batteries, expected to total in the region of 150,000 units by 2024. At around 10kWh per unit (a generous estimate), that equates to around 1.5 gigawatt hours of storage.
Forecasts for EVs, on the other hand, predict around 100,000 vehicles a year being bought by 2024 (possibly more), and with an average battery size of at least 40kWh, that will bring in some 4GWh of storage each year.
