Sharp, ABB, SMA and Bosch are among the big names readying new energy storage products for the UK PV market. Andy Colthorpe caught up with them at the Solar Energy UK show to find out what tech fits best for the UK’s nascent storage sector.

Tesla’s much talked about Gigafactory should be up and running in 2017. PV Tech Storage spoke to analyst Dean Frankel of Lux Research about some of the details and talking points of the EV maker’s ambitious plan to hit ‘500,000 battery packs by 2020’.

One of the U.S.‘s largest investor-owned energy utilities, Consolidated Edison (Con Edison), is planning to spend US$200 million on demand reduction technologies. Con Edison has filed a proposal with the New York Public Utilities Commission for a Brooklyn/Queens Demand Management Program (BQDM) that it hopes can defer the US$1 billion cost of building a new substation and expanding two existing ones.

The developing economies of the world are largely located in geographical regions that have abundant renewable energy resources, be they solar, wind, hydro or in some cases geothermal, yet paradoxically at the individual and rural community level, access to energy is often a very real issue. Establishing a continuous chain of temperature controlled cold environments from the point of harvest to the marketplace and on into the home, a ‘cold chain’, is what is required in order to avoid produce spoilage and to connect farmers with higher value market options in distant urban centres or overseas.

PV Tech Storage speaks to Wolfram Walter of German storage designer and manufacturer ASD Sonnenspeicher about a subject close to home, his home. Walter built a battery system for his own PV array, turning it into a business and turning his prized Porsche into a PV-friendly EV along the way.

PV Tech Storage interviews Paul Bundschuh of Ideal Power, whose company will supply Sharp’s new Smartstorage system with power converters and has also developed a three-port hybrid battery converter to better enable grid-resilience and micro grids.

A team at Harvard is pursuing a metal-free battery chemistry based on organic molecules called Quinones. The technology potentially offers an abundant and safe material to use for scaling up flow batteries, but according to the energy storage team at Lux Research in Boston, there are significant limitations based on project cost.

The emerging availability of storage and smart-grid technologies allows communities to meet their energy demands locally. As Andrew Jones of S&C Electric writes, community-owned micro-grids will become an increasingly important element of the future energy system.

Earlier this year New York governor Andrew Cuomo unveiled plans for an “energy modernisation initiative that will fundamentally transform the way electricity is distributed and used in New York State”. This will include the creation of a leading energy storage marketplace, argues Bill Radvak, chief executive officer of American Vanadium, whose company recently installed a vanadium flow battery storage system for New York’s Metropolitan Transport Authority in Manhattan.

SolarCity, one of the largest solar installers and leasing companies in the US, has moved into providing energy storage via pilot programmes for residential and commercial customers in key regional markets including California. Will Craven, director of public affairs and spokesman for SolarCity, discusses the regulatory situation facing the company and others in the rapidly growing area of energy storage-plus-solar.
