With daily power outages lasting 8-12 hours in major cities like Baghdad and Basra, businesses and households are increasingly turning to lithium-ion energy storage systems..
With daily power outages lasting 8-12 hours in major cities like Baghdad and Basra, businesses and households are increasingly turning to lithium-ion energy storage systems..
Lithium-ion batteries dominate 65% of commercial projects, thanks to plunging global prices [1]. Lead-acid batteries still rule households (cheap upfront costs, but oof – those replacement bills!). Solar hybrid systems with storage have grown 200% since 2022 [3]. Fun fact: A Baghdad supplier told. .
The average price of lithium-ion battery packs dropped by 20% in 2024 compared to the previous year. This drop is attributed to the abundance of raw materials and intense market competition. These global cost reductions may translate into lower prices for imported solar storage systems in Iraq. [pdf]
With ongoing climate change, countries around the globe need to decarbonise to prevent a climate disaster. Around 15% of global CO2emissions come from road transport, and electric vehicles (EVs) are one option to reduce the carbon footprint.
