INSIDE IPVEA
Linde and Dr. Schenk were two of the IPVEA member companies that opted to sponsor a ‘pod’ on the association’s pavilion booth at EU PVSEC, they had this to say:
‘Sponsoring a pod on the IPVEA booth provided us with a good, central information point for customers, with the added value of excellent refreshment and meeting facilities.’ The planning and design team were both efficient and responsive and the finished result was exactly as the specifications described.’ ‘Dr. Schenk GmbH was happy to exhibit at this year’s EU PVSEC as part of the IPVEA membership booth. Given the downturn in the solar industry we were looking for ways to plan and execute our marketing activities for the solar market in a way that would not stretch the budget too much. The IPVEA booth was a very good solution for all members to be present at EU PVSEC and be available for customers. We will consider this participation form again for coming shows and would like to thank IPVEA for the excellent organization of this event.’

EXCLUSIVE by Sara Ver-Bruggen
With batteries Breaking down the grid market energy storage opportunity
Batteries, which cover a range of technologies, are suitable for stationary grid storage applications both at the utilityscale and for smaller applications, or so-called residential and community storage. Unlike the electric vehicle market, which is suffering from overcapacity in battery production, in the coming years growth opportunities for grid connected stationary energy storage will drive demand for conventional, new and emerging battery technologies that are being developed for the specific demands of grid storage. Utility-scale stationary energy storage versus community/residential storage The utility-scale market will take time to establish itself as utilities are conservative and risk averse. According to Pike Research (part of Navigant Consulting) reduced costs, regulatory support and business model clarification is required for utility-scale storage to become established. Pike Research values to the global market at $1.5 billion by 2015. Few markets have demonstration projects for utility-scale battery based energy storage. They include China and the US. Though they require much fewer batteries than utility-scale stationary storage applications banks, community/ residential storage demonstration projects are increasing in number worldwide, in

markets such as the US state of California, Japan, South Korea and the UK, where the government is providing support to some projects that will piloting battery storage to alleviate pressure on the low voltage (LV) network that the predicted increase in PV systems, heat pumps, electric vehicles and other low carbon technologies will add. Similarly, Southern California Edison in the US, announced in November 2012 that it was planning to pilot distributed energy storage as a potential alternative to having to upgrade its distribution systems from 4 KV to 12 KW, for instance, or to avoid connecting up lower KV systems to higher ones that are not close by to each other. Using distributed storage can avoid expensive operations of digging up roads and laying more cabling infrastructure.
FEATURE
Pike Research forecasts the residential/community energy storage market to be worth an estimated $153.8 million by 2015. Though smaller than the utility-scale energy storage market, there are strong drivers for smaller scale grid connected storage in both mature and developing markets, for instance to enable higher penetration of renewables into the electricity mix. Pike Research forecasts the residential/community energy storage market to be worth an estimated $153.8 million by 2015. Though smaller than the utilityscale energy storage market, there are strong drivers for smaller scale grid connected storage in both mature and developing markets, for instance to enable higher penetration of renewables into the electricity mix. According to a report published in 2012 produced for the UK government the value in the majority of future storage installations lies in distributed storage on the semi-urban network. Instances of partnerships between solar suppliers and companies supplying energy storage systems and technologies are increasing in order to develop opportunities that are emerging. Challenges remain, however. Pike Research cites regulatory hurdles and definitions which complicate ownership models, as well as high capital expenditure (CapEx) for battery technologies in large formats and a lack of concrete successful business models at this early stage in the market’s evolution. Today the most popular primary applications for advanced battery in stationary storage applications is for load levelling/peak shifting, where
typically sodium-sulfur (NaS) batteries are used. Other primary applications for batteries include integration of renewables, where NaS as well as flow and lead acid batteries are used. For frequency regulation as the primary application lithium ion (liion) batteries tend to be used. Nickel cadmium (NiCd) batteries tend to be favoured where spinning reserves is the main application. In Q2 2012, nearly 250 MW of installed capcity of NaS batteries were used for load levelling/peak shifting, according to Pike Research, with around 25 MW of installed li-ion battery capacity for frequency regulation applications. New wave of battery technologies for grid market applications However as various regions, such as Europe, increase renewables capacity to meet carbon reduction targets, many companies are bringing to market new cost-effective, scalable and safe battery technologies. One of these is US start-up Aquion

Energy, which is targeting grid services markets with its battery technology for deep-energy-dailycycling, applications (four or more hours), such as load shifting, diesel optimisation, renewables integration and transmission and distribution (T&D) referral. The company’s technology is also suitable for off-grid and micro-grid markets. Aquion was spun out of Carnegie Mellon University in 2009 and is headquartered in Pittsburgh. The battery is based on a propriety aqueous hybrid ion (AHI) chemistry, to provide superior life, safety, durability, and low system costs. The anode consists of activated carbon, the cathode of manganese oxide and the electrolyte from water based sodium sulphate and the separator from cotton. The battery is sealed in a polypropylene casing, the cells are self-balancing and the architecture is modular and scalable, with no thermal management required, no maintenance and limited balance of system requirements. Aquion will start commercial manufacturing of its batteries in mid2013 from its plant in Westmoreland, Pennsylvania. The company is leasing space within a large existing facility in the East Huntingdon Township from the Regional Industrial Development Corporation of Southwestern Pennsylvania (RIDC). As part of a first phase manufacturing commitment at this site, Aquion aims to create over 400 high-tech manufacturing jobs by the end of 2015. The company is targeting different global markets by various applications, for example rural electrification in Africa, weak grids in India, grid arbitrage in the US and Europe as well as renewables integration globally.

Ambri's liquid metal battery, developed using abundant metals, can store large amounts of energy and respond in milliseconds, important for integrating wind and solar into the grid
Another company, Ambri (formerly Liquid Metal Battery Technology), is targeting grid-scale opportunities for energy storage provided by the increased use of intermittent renewables such as solar and wind. Ambri, which was spun out from Massachusetts Institute of Technology (MIT) in 2010, is backed by investors that include Bill Gates, Total and Khosla Ventures. The company is bringing to market an all-liquid battery – a process known as reversible ambipolar electrolysis. The design avoids cycle-to-cycle capacity fade. This is because the electrodes are reconstituted with each charge through an alloying/dealloying process, enabling the battery to exceed 70% round-trip efficiency without degradation. Abundant materials + existing manufacturing = low cost battery for grid-scale storage Ambri’s cells consist of a molten salt electrolyte that sits between a high density metal on the bottom and a low density metal on top, when heated to the melting point. In a charged state a thermodynamic driving force between the top metal layer and the bottom metal layer creates a cell voltage. The movement of the electrons through the cell generate enough heat to keep the 6 | IPVEA UPDATE | OCTOBER 2012
battery at temperature. An additional advantage is that no thermal management or control is required, ensuring the battery’s simplicity. All components are based on abundant elements. Each cell is a 16-inch square unit containing about 1200 Wh. The cells are then placed into 25 kW (100 kWh) refrigerator-sized modules. To produce commercial grid-scale storage battery banks Ambri will pack the modules into a 40-ft shipping container, rated at 500 kW and 2 MWh storage capacity. Ambri’s strategy to commercialise its technology initially targets applications where large amounts of energy need to be stored and the battery can respond in milliseconds. This will potentially open up markets where Ambri can charge premium prices for storing and delivering electricity to the grid to make up for fluctuations in supply and demand, which will become more acute as more wind and solar power is installed. To reduce capital costs in future Ambri has created a battery design that can be fabricated in existing factories using contract manufacturing. The recent fate of A123, which filed for bankruptcy in December, suggests that developing new, potentially

However by exploiting abundant materials for their respective battery technologies, nascent players such as Ambi and Aquion are keeping cost at the forefront, because for intermittent renewables to become a mainstream form of energy generation, low-cost high performance storage technologies are going to be absolutely critical in the coming years. Speaking at a TED conference earlier this year, professor Don Sadoway, the inventor of Ambri’s liquid metal battery, said: ‘The need for grid level storage is compelling, but the fact is today there is simply no battery technology capable of meeting the demanding performance requirements of the grid, namely uncommonly high power, long service lifetime and super-low-cost. We need to think about the problem differently. We need to think big and we need to think cheap ... let’s invent to the price point of the electricity market.’
