Following on from our look at some of the takeovers of promising or already-prolific energy storage companies in the last edition of PV Tech Power, here’s an exclusive interview with Convergent Energy + Power CEO Johannes Ritterhausen.
Lithium-ion batteries are far more widely recycled than many people think, while China and South Korea are already leaders of the emerging circular economy of lithium, a report commissioned by the Swedish Energy Agency has found.
A large-scale lead carbon battery energy storage system has gone into operation in Saxony, Germany to help regulate frequency of the grid, the latest of several such projects in the country by consortium Upside Group.
Portugal’s EDP has inked a deal for its largest PV project to date, a 3.8MWp solar-plus-storage duo it will develop for lead acid battery and storage system maker Exide Technologies.
Daystar Power, a clean energy supplier based in Africa, has teamed up with Nigerian retail banking group Unity Bank to power the latter’s switch away from diesel, using renewable energy and energy storage.
The remote Isle of Eigg, one of the Scottish Hebridean islands, is now host to a hybrid microgrid which incorporates flywheels and ultracapacitors for high power functions as well as solar, batteries, wind and diesel backup.
Johnson Controls has sold off its power business, including its design and production of automotive batteries, to focus on management solutions for buildings and HVAC systems for industrial customers.
Despite the growing interest and deployment figures for lithium-ion batteries for stationary energy storage, its ‘predecessor’ lead acid still has a strong role to play in enabling more and more people to go solar, a representative of Trojan Battery has argued.
Leclanché and VRB Energy, two providers in very different areas of energy storage, have struck up joint ventures (JVs) intended to assist them in scaling up and hitting new markets, while Ice Energy has netted fresh funding.
A veteran of Kenya’s renewable energy industry has argued strongly in favour of lead acid batteries over lithium-ion, in response to a recent Energy-Storage.news article on off-grid solar PV in Africa.
Providers of solar-plus-storage into the continent of Africa have said that it is a misconception that lead acid batteries used in off-grid systems are recycled efficiently back into the supply chain.
The huge increase in demand for safe and reliable batteries to store energy from renewable sources such as solar and wind heralds a new lease of life for advanced lead batteries, argues Dr Andy Bush of the International Lead Association.
Younicos will carry out another project to retrofit lithium-ion batteries in replacement for an existing lead acid battery system at a wind farm, this time in Hawaii.
India-based promoter of decentralised power Clean Energy Access Network (CLEAN) has issued a request for proposal (RfP) for lithium-ion technology providers to show how their solutions can aid mini grid and distributed renewable energy development in India.
Battery vendors are being hit by a combination of rising prices for raw materials and continuing currency uncertainty, resulting in rapidly changing costs for businesses according to Easystart.
French car maker Renault has brokered a partnership to provide second-life battery units to UK home storage supplier Powervault.
Axion Power International, focusing on “hybrid battery technology” that combines lead acid with the properties of carbon-based supercapacitors, has warned that it is in financial trouble after failed attempts to commercialise its devices.
The complexities of combining batteries and solar microgrids are explained by Sam Duby, who is co-founder and director of research and development at mini-grid technologies company SteamaCo Ltd and consults for TFE Consulting. TFE Consulting is a strategy consulting firm focusing on accelerating the energy transition in emerging markets and is active in Africa, India, Southeast Asia and Latin America.
The Advanced Lead Acid Battery Consortium (ALABC) has set out a three-year research programme to improve the performance of lead batteries in energy storage and electric vehicles. It has called for investment of up to US$2 million per year from governments and research agencies to fund its studies, which will run through 2018.
RWE International SE (innogy), a leading European energy company, has signed a share purchase agreement to takeover German solar and energy storage specialist Belectric.
Trina Best, the energy storage company begun as part of Trina Solar but now a separate entity in its own right, wants to go public by 2020 and has not ruled out building its own battery cell production facilities in future.
News in brief: Korea’s main utility and Samsung SDI have overseas markets in their sights, Leclanché subsidiary targets US and Canada, UK lead acid maker moves to Li-Ion with new crowdfund drive.
ABB has signed a memorandum of understanding (MoU) with Chennai-based engineering and research organisation, the Indian Institute of Technology Madras (IITM) to partner on building microgrids and develop R&D in the battery energy storage area.
Through a brief history of batteries and some findings from his own team’s work, Volker Wachenfeld of SMA Solar Technology answers a frequently asked question in energy storage; how can compatibility with the existing variety of batteries in the market be put into practice?
Trojan Battery, manufacturer of deep-cycle lead acid batteries, has announced that it is expanding its research and development capabilities with a new facility in Sligo, Ireland.
S&C Electric Europe has used locally-sourced lead acid batteries combined with 80W solar panels to provide electricity for two primary schools in Zambia.
A large-scale storage system co-located at a German solar farm by the PV plant’s developer Belectric, has been given the green light to operate in the grid-balancing frequency response market.
The failure of a grid-connected storage system at a solar farm in Hawaii is part of the learning process the US island state is undergoing to integrate more PV using storage, according to analyst Dean Frankel at Lux Research.
An antenna tower in Australia serving a broadcaster will be the site of a solar-plus-storage project funded by the German government and designed to deliver power 24 hours a day.
Battery maker Trojan claims its new proprietary ‘Smart Carbon’ technology can improve the cycle life of lead acid batteries by as much as 15%, through effective management of the cell in a partial state of charge.
