The global smart grid, battery storage and energy efficiency sectors attracted just $102 million in venture capital (VC) funding in the third quarter (Q3) of the year, according to the latest quarterly report by Mercom Capital.
In Q2, that figure was $433 million as venture capitalists rowed back their investment in these technologies.
Funding in the smart grid sector was a meager $11 million, which Mercom reports is the lowest quarterly figure it has recorded since it began tracking funding activity. There were just seven deals in Q3, compared to 15 deals in Q2 that raised $222 million. Year on year the trend is the same Q3 2015 saw $81 million raised in 12 deals.
Battery storage companies also experienced a tightening of the VC belt, with $30 million raised across nine deals. This is in stark contrast to Q2, when 10 deals saw $125 million raised during a busy summer period of investment. Equally, year on year Q3s figures were anemic next to 2015, when $96 million was raised across nine deals.
The key areas of activity within battery funding focused on six sub-technologies, Mercom said: supercapacitor, lithium-based batteries, energy storage management software, energy storage systems, thermal energy storage, and flow batteries.
