Power Storage Systems (PSS)
What the battery module is to a car, PSS is to the grid. Simply put, PSS are big batteries that are used to store RSS-generated energy for use when the sun isn’t shining and the wind isn’t blowing. PSS systems have been in development for years, however only recently have they received a lot of attention. This is closely related to the parallel developments in cutting greenhouse gas emissions. But also in response to the inherent problem of RES not being able to produce electricity all of the time.
EEIG has partnered with one of the world’s leading companies that is developing PSS for grid and commercial applications. We aim to promote the widespread distribution of these systems as another component in the global toolbox against the effects of climate change.
Research & Development
Although the components of lithium-ion batteries can be summarised into three basic parts and the only a handful of raw material components are needed to build batteries, the science behind the batteries is extremely complex. Researchers have been working for decades, continually improving the chemical composition of rechargeable batteries, their goal being to continually increase the batteries’ energy density.
The difference between batteries used in EVs and PSS is that batteries used for PSS don’t necessarily require such high energy densities and fast charging times, but they do require a long life as they will be charged daily and expect to have discharge times in excess of 8 hours.
EEIG is working with leading R&D to continue to improve the energy densities and lifespans of lithium-ion batteries.
