DOE to Invest in Grid Integration Systems for Solar Energy - 0 views

  •  
    DOE announced on August 12 that it plans to invest up to $24 million over a number of years to develop products that connect solar power systems with the electrical grid in an interactive way. DOE has selected 12 industry teams that will receive $2.9 million in current fiscal year funding to develop conceptual designs and market analyses for such Solar Energy Grid Integration Systems (SEGIS) projects. The projects will focus on solar photovoltaic (PV) systems and will involve such efforts as developing systems that can communicate with an interactive utility grid and advanced power meters to respond to power price changes over the course of a day, systems that can work with energy storage devices and "smart" appliances to respond to utility price signals, and systems that can interact with building energy management systems.

Emerging Trends in Thermal Energy Storage - 1 views

  •  
    "Thermal energy storage (TES) is a system to store thermal energy. TES can be differentiated into three different categories, namely sensible, latent and thermochemical. The main drivers that propel development of TES system are advancements in material sciences and the emergence of smart thermal grid. Although some of the TES system is already mature especially sensible, adoption of this technology is still slow due to lack of awareness from stakeholders to employ this technology as a method to achieve energy efficiency. Furthermore, high cost of new technology and the recent dramatic drop in oil prices have inhibited or slowed the adoption of TES due to less compelling economics. By using Analytical Hierarchy Process (AHP), emerging TES systems based on latent and thermochemical have been identified as the future of TES systems because it shows remarkable performance capabilities. However, strengthening legislation and standardization frameworks need to be done to see wider adoption of TES systems in the future, especially in Europe and North America."

  •  
    NEC Electronics America Inc. introduced to the Americas twenty-two new 16-bit All Flash microcontrollers (MCUs) for compact, low-power, battery-operated, and sensor-enabled systems. Based on NEC Electronics' high-performance 16-bit 78K0R CPU core, the new 78K0R/Kx3-L MCUs offer very low power consumption to extend battery life, and more on-chip integration to help reduce the size and cost of battery-driven and sensor-enabled systems, such as fire and security alarms, meters, industrial sensors, anti-shake digital cameras, handheld medical diagnostics devices, and data-logging and point-of-sale terminals. In addition to low power consumption, the new lineup offers high-performance on-chip oscillators, built-in circuits for sensor functions, and extended system operating time. "As environmental awareness has grown, energy-saving systems have become particularly reliant on MCU technology," said Jim Trent, Vice President, Multipurpose Microcontroller and Automotive Group, NEC Electronics America. "Over the past several years, NEC Electronics has delivered many ultra-low-power 8- and 32-bit MCUs that have met the demand for energy efficiency. With the introduction of the new 78K0R/Kx3-L devices, however, NEC Electronics is now delivering the benefits of energy efficiency in its 16-bit products."

Solar Cooling - 0 views

  •  
    Compared to other solar energy applications, solar cooling is a relatively new, but growing, technology. Many projects using the technology are still for the purposes of demonstration only, but a growing number of systems are being implemented all over the world for conventional use. In order to give an insight into this innovative technology, detailed information about the possible technical applications of solar cooling systems is provided in this section.\n\nPassive solar cooling, based on bioclimatic strategies such as sun protection using natural screening devices or increased cooling by using ponds or water basins o the roof or close to the external walls, is widely applied and should be the first step to take in cooling a building. Such measures are easier and less costly to implement, they decrease the need for additional cooling and, therefore, for additional energy demand (and also for investment). Sufficient insulation of the building also decreases the need for cooling, as well as for heating.\n\nIf the outcome of these measures is not sufficient in itself, a solar assisted cooling system may be an intelligent solution. In solar assisted cooling systems solar heat is used to drive the cooling process for air conditioning in buildings. Instead of using electricity, free solar thermal energy is used for cooling through a thermal-chemical sorption process.\n\n

A blueprint for a European transmission system - 0 views

  • The European Commission’s proposal is supposed to deliver more cross-border electricity transmission.It is an extension of the current system of national-welfare centred regulations, a system which does not target the optimisation of the EU electricity network, and as such is inconsistent with a truly single market. However, the integrated first-best solution – a single European system operator, regulated by a single regulator, which develops the network in coordination with generators and consumers – appears politically infeasible. To overcome this, we propose a bold blueprint for a European system to fund andincentivise infrastructure development. The approach is fourfold: (1) implement vertical unbundling; (2) add a European system-management layer; (3) establish a stringent planningprocess; and (4) phase-in European cost-sharing.

Renewable Energy Focus - 0 views

  •  
    BLYTH, NORTHUMBERLAND, UK, August 4, 2008. The New and Renewable Energy Centre (NaREC) in the UK and CENER, National Renewable Energy Centre of Spain are working together to find new ways of generating and distributing power from small-scale renewables within communities. The one year project will investigate ways to allow communities to generate and use their own power from renewable energy resources, in a reliable and cost-effective way. With increasing use of renewable energy sources, a significant amount of interest has developed across Europe in so-called 'smart-grid' systems better capable of transmitting and distributing power from different renewable resources in a reliable, flexible electrical network. The team is currently identifying existing communities within Spain and the UK with populations of between 10 and 25 000 which can be used as test subjects for 'smart-grid' renewable systems. The project aims to demonstrate the most appropriate technical solutions for integrating low carbon power generation technologies into a localised, community-based electrical system.

US Government Investing up to US $24M To Bring Solar Energy Online - 0 views

  •  
    The U.S. Department of Energy (DOE) Principal Deputy Assistant Secretary for Energy Efficiency and Renewable Energy John Mizroch announced recently that the DOE will invest up to US $24 million -- subject to the availability of funds -- to develop solar energy products that will hopefully accelerate the penetration of solar photovoltaic (PV) systems in the United States. \n\nWhen the projects are combined with the overall industry cost share of up to US $16 million, more than US $40 million in total could be invested in these SEGIS projects, with future federal funding subject to appropriations from Congress.\n\nThe Solar Energy Grid Integration Systems (SEGIS) projects will provide critical research and development (R&D) funding to develop less expensive, higher performing products to enhance the value of solar PV systems to homeowners and business owners. These projects are integral to the Solar America Initiative, which aims to make solar energy cost-competitive with conventional forms of electricity by 2015. \n

UK Behind Marine Renewables' Rising Tide - 0 views

  •  
    It's been a long, challenging endeavor, but there are signs that the economic ecosystem built up around wave and tidal power generation is at long last gathering enough momentum to make the jump from R&D-driven to full-fledged commercial industry. Scotland, with its long stretches of west-facing coastlines, North Atlantic latitude and longstanding tradition of maritime engineering and commerce, is now at the leading edge of change when it comes to fostering development of marine renewables. Wavegen's Limpet 500 system has been pumping electricity from the western Scottish Isle of Islay shoreline since 2000 while the company and project developer npower renewables have continued to move forward with plans to develop the Siadar Wave Energy Project, potentially the first under the Scottish government's Marine Supply Obligation program. Marine Current Turbines is getting ready to flip the switch and fully commission a grid-connected 1.2-megawatt (MW) Seagen tidal turbine-based system in Northern Ireland's Strangford Narrow, while elsewhere in the EU, project developers and the marine renewables community await the much-anticipated commissioning of Pelamis's novel, serpent-like wave power system off the northern Portuguese coast.

Relative material cost: How it affects the solar energy market - 1 views

  • In order to cope with the rising prices and reduce future costs, solar technology manufacturers and PV system developers have been looking for ways to limit the use of copper in projects. Since PV inverters typically account for 9% of PV system costs and most require a significant amount of copper cables, it is a logical first place to start when trying to engineer a solution. Inverter design and technologies In order to cope with the rising costs many inverter manufacturers are looking at designs that limit the amount of copper used throughout a PV system, which in turn can help to drive down balance of system (BOS) costs for their customers.

Kuwait - LS Cable & System wins $110M order - 0 views

  •  
    Kuwait - LS Cable & System wins $110M order LS Cable & System announced that it had secured a 400kV extra-high voltage cable project valued at $110 million (about KRW130 billion) from the Ministry of Electricity and Water of Kuwait. LS Cable & System said it will supply and install 400kV extra-high voltage conductor with insulated cables and connectors on a turnkey basis. LS Cable & System said that unlike ordinary extra-high voltage cable using pure copper for the conductor, the conductor with insulated cables to be installed will be a high-tech cable in which the strands of wire comprising the conductors are coated with enamel to reduce transmission resistance. This raises transmission capacity by more than 20%. When this type of conductor with insulated cable is used, the overall weight and thickness of the cable can be reduced, as much as the transmission resistance falls, greatly reducing the cost of cable manufacturing and power grid implementation.

Superconductivity and the environment: a Roadmap - 0 views

  • Energy. The Equinox Summit held in Waterloo Canada 2011 (2011 Equinox Summit: Energy 2030 http://wgsi.org/publications-resources) identified electricity use as humanity's largest contributor to greenhouse gas emissions. Our appetite for electricity is growing faster than for any other form of energy. The communiqué from the summit said 'Transforming the ways we generate, distribute and store electricity is among the most pressing challenges facing society today.... If we want to stabilize CO2 levels in our atmosphere at 550 parts per million, all of that growth needs to be met by non-carbon forms of energy' (2011 Equinox Summit: Energy 2030 http://wgsi.org/publications-resources). Superconducting technologies can provide the energy efficiencies to achieve, in the European Union alone, 33–65% of the required reduction in greenhouse gas emissions according to the Kyoto Protocol (Hartikainen et al 2003 Supercond. Sci. Technol.16 963). New technologies would include superconducting energy storage systems to effectively store power generation from renewable sources as well as high-temperature superconducting systems used in generators, transformers and synchronous motors in power stations and heavy-industry facilities. However, to be effective, these systems must be superior to conventional systems and, in reality, market penetration will occur as existing electrical machinery is written off. At current write-off rates, to achieve a 50% transfer to superconducting systems will take 20 years (Hartikainen et al 2003 Supercond. Sci. Technol.16 963).

British Tidal Power System Connected to Grid - 0 views

  •  
    The world's first commercial-scale tidal power turbine has delivered electricity into the British grid for the first time in preparation for full-scale operation, Marine Current Turbines announced yesterday. "SeaGen is the world's first commercial-scale tidal stream generating system by a large margin. It is more than four times as powerful as the world's second most powerful tidal current system, which is our own 300kW SeaFlow, installed off Lynmouth on the north Devon coast more than five years ago." Secretary of State for Energy, John Hutton said: "This kind of world first technology and innovation is key to helping the UK reduce its dependency on fossil fuels and secure its future energy supplies" Marine Current Turbines' next project, announced in February 2008, is a joint initiative with npower renewables to take forward a 10.5MW project using several SeaGen devices off the coast of Anglesey, north Wales. It is hoped the tidal farm will be commissioned in 2011 or 2012. The company is also investigating the potential for tidal energy schemes in other parts of the UK, and in North America.
