The power plant operators do not agree, currently. the energy storage margin is thin and li-ion lifetime too short already... if you refer to grid scale. Look at the APS battery 'event' and the hazard to emergency response personnel batteries pose as a grid asset. Some form of home hybrid using recycled batteries may work, but the safety expertise and market payback don't work except at the DIY scale... Maybe it's a biz opportunity.

That sounds right. What utilities want are components that you install and thereafter take little attention. Re-using recycled batteries does not fit that model. They'd be much happier with something that cost more but lasted 20-30 years.

  It's not even really a question of attention so much as maintenance. Fixed up front costs are easy to handle as capital that can go into their rate cases, but more so power equipment lifetime is measured in decades and the discharge lifecycles of available battery technology is already not great for an installation expected to go to near full discharge on a regular basis. If the planned usage is only a 10% semi-daily scenario for stability support that may result in 5-10 years longer lifetimes versus daily discharges for capacity shifting.
