AES and Siemen's energy storage JV looks to be a comprehensive one-stop shop for energy storage projects of all sizes. Being able to provide the technology, development and financing options makes for a very strong offering. Targeting 160 different countries is some feat too but demonstrates the demand for energy storage solutions from all over the globe. 

Fluence's new Sunflex storage platform is aiming to increase the amount of solar deployed per installation by 50% without affecting the existing grid connection by smoothing solar output and storing energy to dispatch after sunset. This storage solution will also give owners of solar assets access to new revenue streams by providing grid services. I'm sure we are going to be hearing a lot about Fluence in the future.
