Guidehouse forecasts second-life-battery capacity CAGR of 75.7% for EV batteries and 61.3% for PHEV batteries by 2030

A new report from Guidehouse Insights forecasts second-life battery (2LB) available capacity to grow at a 75.7% compound annual growth rate (CAGR) for battery EV (BEV) batteries and a 61.3% CAGR for plug-in hybrid EV (PHEV) batteries by 2030.

According to the report, storage capacity for 2LBs is expected to increase through 2030 due to the rapid adoption of EVs and the trend toward larger EV battery capacities. Growth for this market is largely driven by commercial stakeholders that are identifying opportunities for second life use throughout the EV battery value chain.

Although some policy around second life batteries exists globally, more focus from a regulatory perspective is needed in this market to encourage growth at scale.

The report, Second Life Battery Markets, includes key market trends and policies for 2LB technologies, appropriate applications for these technologies, and an overview of the battery reuse and recycling process.

Forecasts show that pricing for second life batteries is anticipated to remain competitive relative to EV first life batteries (1LBs). The largest market globally lies with the regions that are also leading in EV sales, such as Asia Pacific, Europe, and North America.



There is a lot of money to be made in used EV batteries, and maybe in used EVs.
The batteries have obvious value - the questions is where are they best employed ?
Take a 24 kWh leaf battery. lets say it has 22 kWh left.
Would it be best used in a domestic dwelling as a solar buffer (or a day/night buffer) ?
Or should a company or an office use a small number as a solar buffer?
Or should you gather up say 10-100 of them and used them to buffer the grid ?
if so, who would pay you for this ?
Or would you take them apart for the cells?

Take old EVs.
Could you take the batteries out of them and replace them with higher capacity, same size modern ones ? [ probably no ]
Could you take out knackered batteries and replace them with similar, "low milage" versions ? - Who would certify this ?

Lots of money to be made here, considering the cost / value of batteries and the expected life of EVs.

And I haven't even started on Teslas...

[ There might be a lot of fun with bricking and debricking the cars ... ]
