Redwood Forecasts Second-Life Batteries Could Power 50% of Energy Storage by 2030; Nissan Targets Street Lamps
Redwood suggests end-of-life EV batteries could supply over 50% of the energy storage market by 2030, usable in open-air, low-density systems. Nissan has specifically proposed integrating used 10 kWh car battery modules into street lamps for distributed power.
The discussion splits on EV viability. Some users, like 'UnpledgedCatnapTipper,' argue current range limits, citing 100 miles, are sufficient for daily life. Others, such as 'MangoCats,' maintain second-life batteries suit fixed loads like street lighting even if rapid acceleration performance degrades. Meanwhile, 'bluGill' pointed out the immediate supply bottleneck, noting most current vehicles aren't old enough.
The core consensus supports using these batteries for stationary storage—street lamps, grid modules—over expecting them to replace all gasoline engines immediately. The major fault line remains the timeline: the feasibility hinges on infrastructure deployment (jqubed's solar/Li-Ion concerns) versus the actual, immediate supply of serviceable, aged batteries.
Key Points
Second-life batteries are viable for non-high-demand, fixed power applications.
Users supported this for street lamps and grid modules, noting suitability even if EV acceleration capacity is lost ('MangoCats').
Large-scale battery supply for grid storage is projected to accelerate rapidly.
Redwood stated the potential for these batteries to dominate a huge share of the market by 2030.
The immediate supply of genuinely aged, serviceable EV batteries is questionable.
'bluGill' questioned the current inventory, noting most modern cars are too new to contribute massive supplies.
General EV adoption is criticized for relying on outdated infrastructure paradigms.
Some users defend current EV range ('UnpledgedCatnapTipper'), while others ('MangoCats') demand reliable replacements for varied, long-distance travel.
Technological advancements are focusing on higher density, solid-state chemistry.
Greater Bay Technology announced mass production breakthroughs aiming for GWh-level use and high Wh/kg density.
