Max Bögl Wind AG promotes water battery as a natural large-scale storage facility

Max Bögl Wind AG will present its products with a globally unique natural storage technology at this year’s Energy Storage North America (ESNA) fair in San Diego. From August 8 to 10, the company will present its water battery at booth 629.

MaxBoegl_WaterBattery_Gaildorf

With the water battery, Max Bögl Wind AG has developed a completely new large-scale storage facility. The production of power from renewable energies, such as a solar farm, will be combined with a modern pumped-storage power plant. The water battery can store surplus power from the grid and the energy can be reused as required. It acts as a short-term storage facility and contributes to maintaining stability of the grid, as well as guaranteeing continuous, uninterrupted supply. The pumped-storage power plant is available in three performance classes (16, 24 or 32 MW) and can switch between production and storage within 30 seconds.

The first project is currently being developed in Germany near Stuttgart. It consists of a wind farm with four wind turbines and a pumped-storage power plant with an installed capacity of 16 MW. The new storage concept uses the tower base of the wind turbines as water storage facilities with a storage capacity of 70 MWh. A penstock connect them with a hydroelectric power station and the corresponding lower reservoir 200 meters below in the valley.

Details on new solar-specific AGM battery line from Trojan Battery

Trojan Battery Co., LLC, the world’s leading manufacturer of deep-cycle batteries, today announced the launch of its new line of maintenance-free, true deep-cycle absorbent glass mat (AGM) batteries specifically designed for solar and other renewable energy applications. The new Trojan Solar AGM line is manufactured in the U.S.

Solar AGM

Offering a three-year warranty for stationary applications, and tested to an eight-year design life under IEC 61427 standard for solar batteries, this initial release includes a wide range of Trojan Solar AGM models. With its non-spillable design, the new Trojan Solar AGM batteries enable installers to customize the use and position of the batteries in customer applications, and are certified for non-hazardous shipping per U.S. DOT/IATA regulations.

The Trojan Solar AGM line of batteries will be showcased at Intersolar Europe this week in Munich at the Trojan Battery booth B1.260.

“As we continue to see strong customer interest and demand in applications such as residential storage (both off-grid and grid-tied), solar home systems, microgrids, remote telecom, as well as oil/gas, Trojan’s new line of true deep-cycle Solar AGM batteries has been designed from the ground up and optimized for these types of solar applications and the need for frequent cycling in harsh environments,” said Ganesh Balasubramanian, director of new market development for Trojan Battery. “Trojan continues to remain the only global battery manufacturer to engineer, and produce only deep-cycle batteries, and now we have leveraged our 90 years of deep-cycle flooded experience into engineering and manufacturing the best cycling AGM battery line batteries for solar applications worldwide.”

Is there a PV storage solution between lead-acid and lithium ion?

The new Trojan Solar AGM battery line extends Trojan’s robust offering of maintenance-free, deep-cycle batteries specifically designed for renewable energy applications. This battery family joins Trojan’s current Smart Carbon deep-cycle flooded batteries which feature Trojan’s proprietary carbon additive that helps reduce the effects of Partial State of Charge (PSOC) or undercharging which is common in renewable energy applications. Operating at PSOC on a regular basis can quickly diminish the overall life of a battery, which results in frequent and costly battery replacements.

“With batteries being one of the most expensive components of a battery-based solar system, it is critical to maximize the life of the battery bank to reduce the total cost of ownership of a system,” said Michael Grundke, general manager of EMEA for Trojan Battery. “Trojan’s new Solar AGM line illustrates the company’s commitment to offering reliable energy storage solutions for a wide range of renewable energy market segments. Trojan continues its focus on being an innovative leader in the energy storage space.”

Trojan’s Solar battery line incorporates a wide range of advanced technical features including a robust proprietary paste, advanced plate design and premium separators for overall extended lifecycle, and optimized for total cost ownership. In addition, Trojan’s new deep-cycle Solar AGM batteries are temperature tolerant, shock and vibration resistant and have a low internal resistance for higher discharge current and higher charging efficiency. These features make it the ideal battery for the harsh and demanding environments of off-grid as well as grid-connected systems with frequent cycling needs.

This new residential battery management system is available via Open Source License

Battery Bank

The Digital Microgrid Initiative P.B.C. (DMI), is a public benefit corporation organized to provide clean, reliable and inexpensive electric power to remote areas where grid power is unreliable or non-existent. All profits are reinvested to provide more cost-effective solutions to further the company’s mission of providing clean, low-cost electric power where the need is greatest. The first Digital Microgrid products will be shipped in June and will include a highly modular family of off-grid solar energy systems with a starting price of under $5,000.

DMI’s next move is to make its residential battery management system (BMS) available to battery manufacturers and others under an MIT Open Source License. The BMS hardware is used as a building block providing safety and longevity for batteries in residential energy storage applications. DMI’s hardware is designed to handle a variety of battery chemistries. Within DMI’s solar power systems, batteries of various capacities and characteristics can be mixed to allow simple expansion and system growth to megawatt and megawatt-hour capacity.

Co-President Gene Krzywinski describes why DMI is sharing it’s technology: “Unlike other home appliances, residential grid independence is still dependent on proprietary solutions. We want replacing batteries in home energy storage to be as simple as putting an AA cell in your TV remote.”

Bill Southworth, DMI co-President, describes the market need: “All residential solar power in the future will live hand-in-hand with residential energy storage. Independent solar installers will continue and expand their role as the main retail provider of home solar. As the solar market continues to expand while net metering declines, the majority of new homes and apartments will incorporate solar independence into their construction. We all need simpler and more standardized solutions.”

Inside the system

For battery manufacturers and equipment developers interested in the Open Source program as well as other cooperation on standards, DMI will publish schematics, materials list, API specifications, PC layout and fabrication (Gerber) files. The 80×120 mm BMS is isolated for use in high voltage packs and will manage LiFePO4, lithium titanate (LTO), AGM, and NMC packs. Multiple BMS cards may be used with multiple 48 volt packs in a single high voltage battery. The BMS cards jointly report cell state-of-charge and provide cell balancing on each cell in the battery. A published API is provided describing the communication protocol. The BMS cards are programmed for maximum and minimum cell voltage, but can also be used with sophisticated learning systems for SOC optimization in a dynamic environment such as residential solar. In the DMI system, each battery has its own 8 kW charge/discharge controller and an unlimited number of batteries can be used on a 380 volt bus for megawatt level solutions.
