Highpower ESS

Highpower International has received Rmb3.86m ($622,200) from state funds to develop its PV and off-grid energy storage systems (ESS).

The funds, given by Development and Reform Commission of Shenzhen Municipality, will be mainly spent on development and production equipment in order to accelerate production for Highpower’s residential ESS, the company said.

Highpower’s subsidiary Icon Energy Systems recently introduced an ESS-line, which features a lithium-ion battery, solar cell panel and inverter output device, charged by PV and commercial grid. The product line ranges from 0.5kWh to 15kWh and aims to serve the needs of commercial and residential power systems, solar power, back-up emergency power and outdoor uses.

George Pan, chairman and CEO of Highpower said: “Both central and local governments of China are committed to nurturing and favoring the development of the clean energy industry. We continue to benefit from increasing government support and intend to leverage our expertise and production capability to increase our pipeline of rechargeable battery products.”

The global energy storage market is expected to grow fast over the next years. According to Navigant Research, the micro grid market will increase from $4.3 billion to $19.9 billion in 2020.

Battery supplier Highpower also manufactures consumer-oriented chargers for e-bikes as well as lithium and nickel-metal hydride-based batteries.

AU Optronics introduces li-ion storage system in Australia, Japan and Europe

AU Optronics

Taiwan AU Optronics (AUO) has launched an energy storage system (ESS) PowerLegato for commercial and residential use after being certified by German testing house TÜV Rheinland.

The self-claimed high density ESS provides a 48V lithium-ion battery produced in Japan and features over current, temperature, voltage and undervoltage protection. The system is available in 2.4kWh, 4.8kWh and 7.2kWh. It supports hybrid energy inputs and outputs and has the option to choose between PV DC and grid AC sources.

The system can also operate fully stand-alone off grid in Germany as well as the UK and can serve as emergency backup, according to the company. It also fulfills the qualifications for the Japanese S-mark incentive programme, allowing owners to receive subsidies.

According to AUO, the ESS can store 25% more energy per kg than its competitors.

The residential version entered the European market in 2013 and was awarded for its design by iF and Reddot.

German research centre Karlsruhe Institute of Technology (KIT) recently warned about safety issues of non-certified residential ESS.

UK’s National Grid: Battery energy storage too costly for balancing services

Thu, 07/10/2014 - 10:02 -- Editor
National grid

Battery energy storage costs need to fall by as much as 99% to be competitive with other grid balancing technologies, according to UK transmission system operator National Grid.

In a report published on 10 July, Future Energy Scenarios 2014, National Grid explored the number of years taken to recover the cost of sodium sulphur and lithium-ion batteries through revenue from individual reserve services – Short Term Operating Reserve (STOR) and Fast Reserve - and the decrease in total plant costs that would be necessary in order to recover costs.

ACME to install lithium-ion battery storage in Africa

Wed, 07/09/2014 - 11:35 -- Laura Varriale
ACME PV

Indian-based solar and telecom equipment supplier ACME has struck a deal for a telecom firm to deliver lithium-ion batteries for energy storage solutions to Africa.

Details of the contract were not disclosed. ACME and its Korean partner Samsung SDI aim to sell up to 110MWh of lithium-ion batteries by 2016 in India and Africa in telecom, solar power, defense sectors and other related industries.

Harish Goyal, chief marketing officer at ACME highlighted that lithium-ion battery storage is the future of energy storage and added: “This green solution has revolutionized the way we store energy by efficiently managing the energy needs in the financially competitive market segment while being challenged environmentally."

This will help users to replace their diesel generators and cut down on the carbon foortprint with higher efficiency," Goyal claimed. It is ACME’s business entry into Africa, a continent with a high usage of polluting fuel-based energy generation.

While battery storage systems have a miniscule share in the overall energy storage segment, it is estimated to capture 50% share globally in this segment by year 2020

The delivery to Africa is expected to be ready by September this year. ACME is currently replacing its lead-acid batteries with storage systems using Samsung SDI’s lithium-ion batteries.
