emission reduction have incentivized BESS adoption. Growing
awareness of climate change and the need for clean energy is
also driving public support for BESS technologies.
As battery technology continues to evolve,
costs will reduce, and applications grow,
their impact will only broaden and deepen.
This remarkable evolution, driven by the
unwavering pursuit of a cleaner and more
sustainable future, promises to reshape the
very way we generate, store, and utilize energy.
While lithium batteries are the primary choice of battery technology for BESS,
there are many other technologies that are in place and emerging:
