Baker Tilly has analysed 434 Energy Storage companies globally.. Energy Storage is a system that allows the collection and conservation of the energy created to be used at another time or in a different way, with the main objective of creating a more stable, reliable and efficient energy infrastructure. 

The costs of energy storage are inversely proportional to the amount of investment made in the Energy Storage sector. Thus, the growing investment The growth of the last few years has brought a reduction in the costs that the companies involved in this activity have to assume, thus causing an even greater growth.v




  • Energy storage makes it possible to stabilise unpredictable variations in energy flows, making them more constant.
  • If this system is integrated into the energy supply grid, the stored energy can replace the energy flow if the supply is cut off or the grid stops working at any time.
  • It conserves excess energy created and thus prevents it from being wasted.
  • In some regions, the cost of energy supply varies considerably depending on the season. Thanks to Energy Storage, this can be avoided, as it allows the previously stored energy to be used in those periods when the cost of energy is excessively high.


Since 2012, investments in the Energy Storage sector have experienced moderate but steady growth, raising more than $550 million in funding in 2018 alone.

The vast majority of the funding rounds launched in 2019 have been A Rounds, i.e. first rounds, due to the fact that it is a new and emerging sector and the companies dedicated to the Energy Storage sector are small but highly innovative firms with great growth potential.

For example, Advano raised USD 15 million in its first round of funding, and Titan Advanced Energy Solutions 10 million, also in its Round A.

Regarding B Rounds, Energy Vault received an investment valued 110 million in the same year.
