First developed by NASA, flow batteries are a potential answer to storing solar – and wind – for eight to 10 hours, far beyond what is commonly achieved today with lithium-ion. In the first of a two-part special report, Andy Colthorpe learns what the flow battery industry faces in the fight for commercialisation.
SunEdison founder and solar financing pioneer Jigar Shah talked to Andy Colthorpe about having the ‘freedom to invest’ for the biggest impact and why, with traditional lenders still reluctant to finance energy storage, there will always be space for frontrunners who are able to properly understand the value propositions of new and innovative sustainable technologies.
The digital ledger system blockchain has been both praised and misunderstood in equal measure and its relationship to the physical world of electrons is at its earliest stages of exploration. In the latest ‘Storage & Smart Power’ section of PV Tech Power, Carsten Reincke-Collon, CTO of Younicos looks at how energy storage and management software will interact with blockchain-led or blockchain-like systems of data processing and recording.
While it may seem like an obvious choice for US states to include energy storage into their Renewable Portfolio Standard (RPS) commitments, in reality, standalone targets and mandates for energy storage procurement have been preferred.
Our publisher Solar Media produces the quarterly technical journal PV Tech Power, aimed at the downstream end of the solar PV industry, and the September 2017 edition, Volume 12 in the series, is available now.
The key value propositions for commercial energy storage are based around “maximising economics subject to operating constraints”, according to Stem and other energy storage system integrators and operators.
