What is an Energy Storage System (ESS)?

An Energy Storage System (ESS) is equipment made to store various types of energy efficiently and safely. The term has gained attention due to the rise of EV’s and solar panels, which often use lithium-ion batteries as Energy Storage Systems (ESS). The surging demand to reduce greenhouse gases is also contributing to the growth of the ESS market.

What are the different types of space storage devices?

Given electricity is the underlying power source for almost all activities in space, the most common types of storage devices arebatteries and capacitors. Also being developed are regenerative fuel cells, basically a standard fuel cell run in reverse when energy is plentiful, that can then, when needed be reversed again when energy is needed.

What is the energy storage spacefund reality rating?

The Energy Storage SpaceFund Reality rating (SFR) is a detailed database of over 15 companies from all over the world that are either actively creating, or planning to create, technology and services to improve energy storage in space. Each company has been assigned an SFR rating based on our analysis, publicly available data, and expert insights.

Why do we need constant and reliable energy in space?

In space the need for constant and reliable energy is alife and death matter. No matter the source of the energy, the contingency always exists that it will fail, either predictably, as in the long day night cycle of the Moon or in Earth orbit, or in an emergency breakdown of the energy generation system.
