Generac genset

Generac has launched a low cost per kW protection standby 22kW generator.

The Guardian genset series comes with the company’s purpose-built OHVI engine and controller, including a dual-line tri-lingual LCD display.

The genset is engineered for standby power applications and includes a feature to ensure reliable operation to power sensitive electronics and appliances, according to the company. The engine runs at 1800rpm, which makes it quieter, less fuel consuming and extends therefore the service life of engine and alternator.

“Previously, if a homeowner needed a generator with a little more ‘oomph’ than they could get from a 20kW home standby, they’d have to invest several thousand dollars more for a 22kW liquid-cooled generator,” said Jake Thomas, senior product manager at Generac. The 22kW air-cooled home standby should set a new price and performance benchmark claimed the company. The recommended retail price of the new series is $4,699. “Our new 22kW Guardian Series generator provides that extra power for only a few hundred dollars more. That’s a tremendous value for our customers,” added Thomas.

The genset is compatible with a remote monitoring system that allows US and Canadian homeowners to monitor the status of their power system via electronical devices.

Toshiba has added a 1000kVA UPS for data centres and other mission-critical facilities to its G9000 product line.

The double-conversion system has a capacity of 1000kVA/1000kW and provides reliable power at up to 97% AC/DC/AC efficiency at loads from 50 to 100%, according to the company. At 20% load, it should still have an efficiency of 95%. The input power factor is greater than 0.99, the input voltage ranges is from 15% to -20% and the output power factor is rated at unity. The company claimed that the UPS is the largest unit yet of its G9000 products.

The UPS was developed at Toshiba’s Houston facility in the US and is designed for stand-alone or parallel use in up to eight unit configurations without requiring paralleling or load sharing intelligence in the switchgear cabinet. The UPS aims further to support 100% step-load changes without battery discharge. The dynamic response of the inverter shall eliminate the need for an output transformer.

The UPS comes with a three-year onsite warranty. Other units of G9000 line have a capacity ranging from 100 to 750kVA.

Ideal Power hybrid converter

At the Intersolar North America conference in San Francisco, Ideal Power has introduced a three-port, 30kW hybrid converter family for off-grid, grid-tied and grid resilient applications to integrate energy storage and solar power.

The developer of disruptive power conversion stated that due to an improvement in size, weight, cost and efficiency, the converter is able to integrate multiple power sources while lowering the cost of delivering grid resiliency during blackouts and reducing dependency on diesel fuel for off-grid applications.

The hybrid converter production line uses the company’s Power Packet Switching Architecture in a three-port product. This shall allow to combine PV inverter capabilities on one DC port, bi-directional battery converter capabilities on the second DC port and provide an AC port supporting both grid-tied and off-grid applications.

"We also expect our hybrid converter to improve modularity and interoperability, so that microgrid systems can migrate from custom engineered projects to using standard plug-and-play components," said Dan Brdar, chief executive officer of Ideal Power.

Ideal Power said during Intersolar North America that it expects the initial installation of the system in commercial buildings that have to improve grid resiliency to blackouts.  

At Intersolar Europe, the hybrid converter received the 2014 electrical energy storage award for energy efficiency improvement and cost effectiveness of combined energy storage and PV applications.

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.

Crestchic delivers loadbank for BAS in Antarctica

Crestchic loadbank

British Antarctic Survey (BAS) has installed a second loadbank from UK-based manufacturer Crestchic to secure critical data and the livelihood of scientists at two primary research stations in Antarctica.

The resistive-only loadbank provides 200kW to ensure that generators do not lose power in the acute period of the Antarctic summer and winter peak season and to protect received data.

During the summer, temperatures remain close to freezing and in the winter, temperatures drop as low as -30°C at the remote BAS research centres.

Because of the lack of an electrical grid, the data backup and safety of the scientists depends on the power of the generators at the primary stations Halley and Rothera. The second loadbank was installed at the Rothera station, after the first loadbank was delivered to Halley.

“You can’t survive here without resilient generators and we can’t afford to lose the power so the loadbanks are critical for our operation out in Antarctica,” said Mark Wales, facilities manager at BAS.

Halley, where the ozone hole was discovered in 1985, lies within an auroral zone on the Brunt Ice Shelf and is suited for “space weather” research. At Rothera, located on Adelaide Island, the BAS researches glaciology, geology, geophysics and biology.

FuelCell Energy

US Department of Energy (DOE) has awarded FuelCell Energy with a $900,000 grant to produce a system of distributed hydrogen production.

FuelCell will develop an electrochemical reactor using the company’s commercial carbonate fuel cell stacks to produce a distributed hydrogen generation method. The new system shall allow hydrogen to be generated more efficiently where it is needed rather than on a large scale at a central plant. According to the company, distributed hydrogen generation would reduce transportation costs and provide reliable fuel supply.

The grant is part of a $20m support to advance hydrogen production and delivery technologies.

"Developing technologies that can economically produce and deliver hydrogen to power fuel cells from diverse, domestic and renewable resources can enable substantial reductions in energy use and carbon emissions," federal energy officials said.

“This award from the U.S. Department of Energy will get the R&D started on this concept, which could be an attractive approach to generate hydrogen in a low or carbon-neutral manner," said Anthony Leo, vice president of FuelCell. Using direct fuel stacks makes the stationary fuel cell power plant versatile, claimed Leo.

The manufacturer recently completed an installation of a 14.9MW fuel cell park in Bridgeport, US, owned by Dominion Corporate.
