Suggested Answer Key
In the last decade, Kazakhstan has been producing more energy from renewable energy sources than it had ever produced before. However, when surplus energy is produced, it needs to be stored.
Kazakhstan is using a few of the energy storage solutions we have looked at to improve on old systems the country had been using previously.
Firstly, Samruk Energy have teamed up for two projects with Primus Power to introduce EnergyPod storage technology to Kazakhstan. These are types of flow battery that have a large capacity and before long, they will have made the grid more efficient.
Kazakhstan also uses pumped hydro storage. This is especially popular in the Almaty region which is home to the majority of Kazakhstan’s hydropower plants.
In Sweden, electricity use per person is very high, but it has one of the lowest CO2 emission rates per capita. This is because more than half of the country's electricity is from renewable sources and generation is almost completely decarbonised. This clean energy is mainly stored in batteries, and many Swedish companies are leading the way in developments in battery technology. Battery storage is probably the most popular solution in countries with a high population density, but in Kazakhstan we have the luxury of space. This means we will be able to build different types of storage facilities, like pumped hydro, which do not contain chemicals like batteries do. In a couple of years, Kazakhstan will have been working on renewable energy solutions for a decade. Who knows how much more progress will have been made by then?
