The tumbling cost of batteries is set to drive a boom in the installation of energy storage systems around the world in the years from now to 2040, according to the latest annual forecast from research company BloombergNEF (BNEF). The global energy storage market (excluding pumped hydro) will grow to a cumulative 942 GW/2,857 GWh by 2040, attracting $1.2 trillion in investment over the next 22 years. Cheap batteries mean that wind and solar will increasingly be able to run when the wind isn’t blowing and the sun isn’t shining.

BNEF’s latest Long-Term Energy Storage Outlook sees the capital cost of a utility-scale lithium-ion battery storage system sliding another 52% between 2018 and 2030, on top of the steep declines seen earlier this decade. This will transform the economic case for batteries in both the vehicle and the electricity sector.

BENF has become much more bullish about storage deployments since their last forecast a year ago. This is partly due to faster-than-expected falls in storage system costs, and partly to a greater focus on two emerging applications for the technology – electric vehicle charging, and energy access in remote regions.”

BNEF sees energy storage growing to a point where it is equivalent to 7% of the total installed power capacity globally in 2040. The majority of storage capacity will be utility-scale until the mid-2030s, when behind the meter applications overtake.

Behind-the-meter, or BTM, installations will be sited at business and industrial premises, and at millions of residential properties. For their owners, they will perform a variety of tasks, including shifting grid demand in order to reduce electricity costs, storing excess rooftop solar output, improving power quality and reliability, and earning fees for helping to smooth voltage on the grid.

China, the U.S., India, Japan, Germany, France, Australia, South Korea and the U.K will be the leading countries. These nine markets will represent two thirds of the installed capacity by 2040. In the near-term, South Korea will dominate the market, the U.S. will take over in the early 2020s, but will be overtaken by China in the 2020s. China will then lead throughout to 2040.

Especially developing countries in Africa will also see rapid growth in battery storage. Utilities are likely to “recognize increasingly that isolated assets combining solar, diesel and batteries are cheaper in far flung sites than either an extension of the main grid or a fossil-only generator,” the report says.

BNEF analysis estimates energy storage build across multiple applications to meet variable supply and demand and to operate the grid more efficiently, while taking into account customer-sited economics for using storage as well as system-level needs. Aggregating BTM energy storage could be a viable alternative to utility-scale for many applications but it will take years before regulatory frameworks in some countries fully allow this.

There is significant opportunity for energy storage to provide flexibility – to help balance variable supply and demand – and systems will undoubtedly be used in complex ways. Energy storage will become a practical alternative to new-build generation or network reinforcement.

Despite the rapid growth from today’s levels, demand for batteries for stationary storage will make up only 7% of total battery demand in 2040. It will be dwarfed by the electrical vehicle market, which will more materially impact the supply-demand balance and prices for metals such as lithium and cobalt.

Es la batería de ión-litio más grande utilizada en una aplicación industrial en Australia hasta la fecha

Kokam Co., Ltd, provider of innovative battery solutions, has announced that it has successfully deployed for Alinta Energy, a leading Australian utility, a 30 MW/11.4 MWh Energy Storage System (ESS), the largest lithium ion battery deployed for industrial application in Australia. The ESS features Kokam’s high power Lithium Nickel Manganese Cobalt (NMC) Oxide battery technology, and is being used to improve the performance of an islanded high voltage network, which supplies power to major iron ore producers in the Pilbara region of Western Australia.

Hybrid natural gas/battery system increases islanded microgrid’s reliability, efficiency, sustainability

Operational since April 2018, the ESS consists of five 2.2 MWh Kokam Containerized ESS (KCE) units using Kokam Ultra High Power Lithium-ion NMC (UHP NMC) batteries. The ESS, in conjunction with Alinta Energy’s existing 178 MW open cycle gas turbine Newman Power Station, serves as a hybrid natural gas/battery energy generation and storage system. This hybrid system, along with a 220 kV high voltage power transmission system and high voltage substations, form an islanded microgrid that is used to power iron ore mines.

In addition to delivering Alinta Energy the ESS used for the project, Kokam, in partnership with EPC contractor UGL Pty Ltd, also served as the system integrator on the energy storage project. Kokam contracted ABB Australia to supply the ABB PowerStore™ “Virtual Generator” used to manage the microgrid. Adding the ESS to the microgrid will improve Alinta Energy’s ability to reliably deliver energy to the region’s iron ore producers.

Alinta Energy’s hybrid natural gas/energy storage system and islanded microgrid demonstrate how innovative technologies, combined with intelligent design, can improve power reliability for industrial customers, while also providing efficiency and sustainability benefits,” said Ike Hong, vice president of Kokam’s Power Solutions Division. “The Alinta Energy Newman Battery Storage Project provides an example of how new high power energy storage technologies enable both utility and industrial customers to build hybrid natural gas/battery systems that increase energy reliability, lower greenhouse gas emissions, and boost their bottom lines.

Growing utility, industrial market opportunities for UHP NMC battery technology

The Alinta Energy project provides an example of the growing number of utility and industrial market opportunities for Kokam’s UHP NMC battery technology. Designed for high-power energy storage applications, the UHP NMC battery technology can be used by utilities and other energy services companies for spinning reserve, frequency regulation, wind or large solar power system ramp rate control, Uninterrupted Power Supply (UPS), voltage support and other applications that require large amounts of power to be dispatched in seconds or less. In addition, the technology’s ability to quickly receive and dispatch very large amounts of power make it particularly well suited to be combined with natural gas, diesel and other power systems used to generate energy for industrial applications, where even a brief power disruption that shuts down mining, off-shore drilling or other industrial operations can result in costs totaling hundreds of thousands or even millions of dollars.

Kokam’s UHP NMC battery technology cost-effectively and reliably delivers the high power needed for these utility and industrial applications, thanks to the technology’s:

High discharge rate: UHP NMC battery technology has a max discharge rate of 10C, compared 3C for competitors. This enables UHPNMC batteries to dispatch more power when needed.
High energy density: The UHP NMC battery technology’s high energy density enables up to 3.77 MWh of energy storage to be installed in a 40 foot container, compared to 3 MWh of energy storage for standard NMC batteries, allowing more energy to be stored in a smaller space.
Long cycle life: UHP NMC batteries can last up to 10,000 cycles, compared to 3,000 – 5,000 cycles for standard NMC technologies, increasing the energy storage system’s expected life.
Improved heat dissipation: With a heat dissipation rate that is 1.6 times better than standard NMC technologies, UHP NMC batteries can be used at a higher rate for longer periods of time with no degradation in battery life or performance.

Akasol, based in Darmstadt (Germany), is now manufacturing lithium-ion battery systems for Daimler subsidiary EvoBus. The leading European bus manufacturer plans to launch its new electric bus Citaro at the 67th IAA Commercial Vehicles in September. These buses will be fitted with up to ten of Akasol’s AKASYSTEM OEM battery packs (max. 243 kWh). The innovative technology combines high demands on performance charging and discharging, energy density and lifespan.

Series manufacturing of the Citaro bus will start this year. “We’re working on this together with Akasol’s experts. Based on the specifications we have developed together, they manufacture battery systems for us with cells from Samsung,” confirms Gustav Tuschen, Head of Product Engineering Daimler Buses and a member of the EvoBus management team. “The batteries are being tempered at about 25°C. With this we expect maximum charging capacity, performance and lifetime.”

Akasol laid the foundation for delivering high performance battery systems to Europe‘s leading bus manufacturers by opening a serial production plant for commercial vehicle battery systems in Langen (Hessen, Germany) in autumn 2017. The facility has a yearly capacity of up to 300 MWh. Akasol believes, that this is Europe’s largest production plant for commercial vehicle lithium-ion battery systems.

Development, testing and validation of the AKASYSTEM OEM battery systems for EvoBus have run since 2015. “It was a great challenge for our company to meet Daimler’s high requirements on one of the most important components of electric power trains”, comments Sven Schulz, Managing Director of Akasol GmbH.

Akasol’s battery systems in the electric Citaro are able to charge rapidly, meet the demands on operating range and also supply additional units such as air conditioning and electrical systems. Between six and ten of Akasol’s safe and powerful battery packs are mounted in the vehicles, partly on the roof, but also in the rear, where they take up the space that was once intended for the diesel engine.

The key factor for meeting our client’s demands on lifetime is our efficient water-cooling. Tempering has been shown to work efficiently and reliably both in winter tests in the north of Sweden where it was incredibly cold as well as on summer drives in the dry desert heat in southern Spain,” reports Sven Schulz. The Citaro bus with electric drive will have an operating range of 150 km (SORT2 cycles, medium traffic). Throughout the coming years operating range shall be continually improved upon.

According to a study by consultancy PwC, there are currently 200 electric buses, but more than 20,000 diesel buses operating in public transport in Germany. This year the number of electric vehicles could double. Cities such as Hamburg and others have announced that by 2020 they will only deploy new, emission-free vehicles such as Citaro E-CELL.

Akasol has developed and sold a range of battery systems for electric and hybrid buses for years. Aside from EvoBus another client of serially produced battery systems is a large European bus manufacturer from Sweden. VDL Bus & Coach (Netherlands) and Alexander Dennis are project-based clients. Electric buses equipped with Akasol’s battery technology operate successfully in London, Berlin, Braunschweig and Cologne amongst other places.

Electro Power Systems S.A. (“EPS”) announces the signing with Endesa of an EPC contract for the design, construction and commissioning of a 20 MW utility-scale storage system.

EPS will deliver a unique turnkey solution for serving Endesa’s thermoelectric plant Carboneras located in Almeria, Spain. The storage system will be the largest in Spain and will be composed by 24 inverters, 16 containers of which 8 for PCS and 8 for Li-ion storage, with a total installed capacity of 20 MW/11.7 MWh.

 

The installation of this utility-scale system aims to make the plant more flexible and improve its response to the load fluctuations in the current electricity system resulting from the intermittency caused by an increased penetration of renewables. The addition of storage is also expected to reduce maintenance costs for the plant’s main components and extend their useful life.

The project is part of the general evolution of the Carboneras coal plant to better serve the current electricity system. A significant penetration of intermittent renewable energies, mainly wind power, are forcing the plant to adjust its production and implement backup functions to meet electricity demand at all times.

The project is scheduled to enter into operation in June 2018.
