Liquid molten salt for Emerson and SolarReserve energy storage project

Tue, 01/22/2013 - 17:36 -- Ruth Williams

Emerson Network Power and SolarReserve are collaborating to produce and store solar energy in liquid molten salt at the Crescent Dunes Solar Energy Project in Nevada. It will be the first project of its kind to harness energy from the sun and store it in this way. The 110-MW project is due to be online by the end of 2013.

Nevada solar park

SolarReserve’s system of 10,500 mirrors focus the sun’s energy to heat molten salt that flows through a central receiver, which sits atop a 540-foot solar power tower. The molten salt then flows up the tower where it circulates through the receiver and is heated by the sun’s energy. It then flows to another storage tank where steam is produced, using thermal energy, which powers a turbine to generate electricity. Excess thermal energy will be stored in the molten salt.

Emerson’s Ovation technology will directly control the circuit and heating process of the molten salt system, the water/steam cycle and auxiliary processes. The control system will also provide supervisory control of the mirrors and interface with the turbine control system. ?

Enough energy is expected to be generated to power 75,000 homes regardless of whether or not the sun is shining.

Cummins is targeting the European rental market with the launch of four generator sets in the 150 to 300 kVA range.

Cummins

According to International Rental News, the rental-specific sets, which have been created by a new Cummins design team led by former A-Plant power rentals director Richard Mellard, are sized at 150, 200, 250 and 300 kVA, with the smaller two using Cummins QSB7 engine and the two larger models equipped with the QSL9 power unit

The sets will be made available in markets including Europe, the Middle East, Asia Pacific and Australia. The reports said Cummins would further expand their rental range, with launches of sub-150 kVA units by the end of 2013 or the start of 2014, and larger units following in 2014/15.

The gensets come equipped with Cummins’ PowerCommand controllers, although Cummins plans to offer third-party controllers for rental companies who want commonality across their fleets. The 150 kVA unit can be used in temperatures up to 500C without any derating and the 200/250/300 sets up to 400C with no derating.

Floating Production Storage and Offloading Vessel over 100MW

Thu, 01/17/2013 - 17:36 -- Ruth Williams

The first ship to use gas engines to produce more than 100MW of power will be in service in Brazil’s offshore oil fields. The P-63 floating production storage and offloading (FPSO) vessel has a Wärtsilä 50DF dual-fuel engine. 

The Wärtsilä engine can run on treated crude or well gas and also on marine diesel oil, meaning almost no marine diesel oil would need to be shipped to the boat. Thus greatly reducing operational costs.

Wärtsilä was contracted by the Brazilian industrial group QUIP, to provide a turnkey package for this vessel. The package includes three main power modules, each comprising two 18-cylinder Wärtsilä 50DF engines in V-configuration, alternators and all required auxiliary equipment, as well as commissioning, start-up, and operational supervision.

Following the completion of load tests in China it will be deployed to Brazil later this year.

Eaton introduces 93PM three-phase UPS series

Tue, 01/15/2013 - 17:36 -- Ruth Williams

Eaton has launched the 93PM series of three-phase UPS covering power ratings from 30 to 50 kVA.

In double conversion mode, the Eaton 93PM units are designed to perform at a 96.7% efficiency. With its Energy Saver System technology, Eaton claims the UPS automatically adapts to incoming power conditions (aka Eco Mode), increasing efficiency to 99%, switching to double conversion or battery mode with a typical transition time of two milliseconds.

The Eaton 93PM claims high power and energy density; the devices are capable of providing the full load with power from the internal batteries for 10-20 minutes. Internal batteries allow the 93PM to achieve a minimal physical footprint of only 0.5 m2, saving valuable space that users can allocate to other business critical equipment.

Additionally, the units are equipped with Eaton’s Advanced Battery Management technology to ensure maximum uptime. ABM optimises battery recharge time, eliminates overcharging, continuously monitors battery condition to extend battery service life by 50%, enables early fault detection and provides optimal maintenance planning. If required, the backup time can further be extended with line-and-match external battery cabinets to provide power for more than an hour.

EU: $6.7 billion earmarked for energy efficiency projects ‘not spent in sensible way’

Tue, 01/15/2013 - 17:36 -- Ruth Williams

The European Union’s auditor says that €5bn ($6.7bn) in funds specifically targeted at energy efficiency projects over the past dozen years were largely ill-spent.

Harald Woegerbauer, who compiled a report for the European Court of Auditors (ECA), said Monday that funds often went to general refurbishment of public buildings, “while energy efficiency was, at best, a secondary concern.”

Returns on the investments were expected only after about 50 years, and sometimes as much as 150 years. The ECA said, “these funds were not spent in a sensible way.”

EU spending is coming under increasing criticism as member nations have to tighten their belts to keep debt within acceptable limits. EU leaders are expected to decide on a new seven-year EU budget next month.

UK fuel cell company turns profit after 20 years

Tue, 01/15/2013 - 17:36 -- Ruth Williams

UK-based Intelligent Energy is the in Britain, and one of the few companies in the world, to make a profit from fuel cell development.

Intelligent Energy has been developing fuel cell technology to be used in cars, power stations and portable electronic devices for 20 years.

Just two years ago Intelligent Energy made a £15million loss, which it has now turned into a £7.8million profit after revenues surged in 2012 by 269%. This demonstrates the considerable growth in the fuel cell industry in recent years.

Intelligent Energy credits a joint venture with Suzuki to manufacture fuel cells for cars as enabling it to become profitable.

It is also leading a consortium to introduce zero carbon emission fuel cell electric taxis to London, is working on fuel cells for back-up power systems to replace traditional diesel generators and has a joint venture with SSE to develop fuel cell combined heat and power systems for use in the home and industry.

Green Grid white paper offers fresh perspective on UPS ‘eco mode’ for data centres

Fri, 01/11/2013 - 17:36 -- Ruth Williams

The Green Grid has published a white paper on how Eco Mode can improve data centre efficiency and overall Power Usage Effectiveness (PUE) when appropriately deployed.

The paper, Evaluation of Eco Mode in Uninterruptible Power Supply Systems, offers an extensive look into UPS systems, and makes recommendations to data centre managers regarding other power distribution equipment to ensure a reliable power system.  

In order to help understand and deploy what is typically the highest-efficiency mode, the white paper breaks down key elements such as UPS technology and performance, critical power systems configuration, IT power supply ride-through, and utility grid reliability. The white paper explores each of these ideas and their trade-offs, helping data centre operators understand Eco Mode from the ground up.

According to The Green Grid, transfer-time is “one of the most salient performance characteristics for eco mode.” This is the amount of time during which the UPS will not output any power.  

Global UPS market to reach $9.84bn by 2015 - report

Thu, 01/10/2013 - 17:36 -- Ruth Williams

The global UPS market will reach $9.84bn by 2015, according to a report by analysts TechNavio.

TechNavio's report, ‘Global Uninterruptible Power Supply Market’, sees the key vendors dominating the UPS market space as Schneider Electric, Emerson Electric, and Eaton.  The other vendors mentioned in the report are Riello, Toshiba, Swelect Energy Systems, Mitsubishi Electric, GE and TDK.

An analyst from TechNavio's Engineering team said: ''The use of next-generation power storage technologies is one of the emerging trends in the UPS market. Such next-generation power storage technologies aid the environment-related efforts of companies.

“Thus, instead of using electricity, many greener methods such as solar and wind energy might be used to charge the batteries in UPS systems. Also, next-generation technology helps to discharge the energy back to the grid when battery power is not in use.''

One of the key factors contributing to this market growth is population growth. However, the increasing cost of raw materials could pose a challenge to the growth of this market, the report says.

Thu, 01/10/2013 - 17:36 -- Ruth Williams

Finnish gas engine manufacturer Wärtsilä is to engineer and supply a 225 MW power plant to South Texas Electric Cooperative (STEC) in the USA.

The STEC Red Gate power plant will be located in Hidalgo County, Texas and is scheduled to be in commercial operation by summer 2014. The plant will be powered by 12 Wärtsilä 50SG engines running on natural gas.

The new Red Gate power plant is designed to meet BACT (Best Available Control Technology) pollution standards as mandated by the United States Clean Air Act.  Wärtsilä  said one of the benefits of the 50SG engine is that its high simple-cycle efficiency is achieved with minimal water consumption.

Wärtsilä has also signed a maintenance agreement to provide technical and operational assistance with maintenance planning, technical advisors, spare parts, and an on-site inventory.

Aggreko provides power for gas exploration in Maranhao

Wed, 01/09/2013 - 17:36 -- Ruth Williams

Temporary power supplier Aggreko is working with Duro Felguera, a specialist geological exploration group from Spain dedicated to developing and executing projects for a number of industrial sectors, including oil and gas. Aggreko is to provide power for Duro Feguera’s research work into natural gas fields in Santo Antonio dos Lopes, in the state of Maranhao, Brazil.

 

Duro Felguera was commissioned to explore areas of Santo Antonio dos Lopes where grid power was not available.  As the search for natural gas requires the use of heavy machinery with large motors that require reliable power, Aggreko was asked to provide 12 generators of various sizes (between 125 kVA and 500 kVA), capable of producing 3.1 MW of power.

Meanwhile, Aggreko has been chosen by one of Brazil’s largest independent renewable power generation companies to conduct performance tests at the Morro do Ventos wind farms in the northeast of the country.

The UK firm will supply load banks – a recreation of the load that a power source will generate – for commissioning tests of the 145 MW wind farms, which are operated by Dobreve Energia. Load bank testing ensures that the wind farm is ready for grid connection.
