The U.S. Department of Energy's National Renewable Energy Laboratory (NREL) and A123Systems have teamed up to support the battery-maker's effort to develop safe, less expensive, more powerful, and longer lasting batteries for hybrid-electric vehicles. The Laboratory and the battery-maker have signed a three-year, Cooperative Research and Development Agreement to examine and develop new techniques to improve thermal management in advanced transportation batteries. "We're pleased to be working with A123Systems on thermal management of their advanced nanophosphate-based lithium ion batteries," NREL Principal Engineer Ahmad Pesaran said. "Batteries with improved thermal behavior are critical for widespread acceptance of affordable hybrid-electric vehicles that consume less fuel and reduced harmful emissions." Hybrid electric vehicles get as much as double the fuel economy of comparable cars. Plug-in hybrids will be even more gasoline-stingy with potential of displacing significant amount of gasoline with electricity for road transportation. To achieve these goals, affordable, high-performance, safe, and long-lasting batteries need to be produced in large quantities. Propulsion batteries - batteries that power an electric motor to assist moving a car - are key components of hybrid-electric vehicles, and will be more important in the plug-in hybrid and extended range electric cars of the future. By better understanding the thermal behavior of advanced batteries, NREL researchers will help A123Systems engineers design improved thermal management systems and to optimize the design of the battery cell and develop a battery pack that's lighter, cheaper and more durable.

"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."

This technology seems to me to be much more beneficial on a local scale, what if every home had its own battery, then home power generation becomes economically more viable for everyone. If you could show that a system like this could pay for itself in say 5 years then every home would want one. Plus for this to be implemented on a large scale requires massive investment that could be decades away. Share the technology and lets get it in homes by next year. Great ted talk. Jon Senior 0 Reply 1 hour ago: I agree 100%. Localised energy production would also make energy consumers more conscious of their consumption and encourage efforts to reduce it. We can invent and invent all we want, but the fast solution to allowing renewable energies to take centre stage is to reduce the base energy draw. With lower baseline consumption, smaller "always on" generators are required to keep the grid operational. Town and house-l

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

6) Electro-thermal recapture - converting the thermal energy wasted from the exhaust back into electric power. It's not available yet but, according to Origo Industries' Ian Houston and Oaktec's Paul Andrews, both believe the exhaust is the greatest waste of energy in the car and that this will be the next big leap for the hybrid car industry.

"According to Sunderland and Davis, the benefits of combining thermally conductive Makrolon® TC8030 polycarbonate with polyurethane encapsulation technology utilizing Bayflex® polyurethane reaction injection molding (RIM) technology include: reducing the bill of materials increasing manufacturing flexibility, and reducing the weight for many electronic components"

Recent research into the properties of graphene nanoribbons provides two new reasons for using the material as interconnects in future computer chips. In widths as narrow as 16 nanometers, graphene has a current carrying capacity approximately a thousand times greater than copper - while providing improved thermal conductivity.

"Developed by Prysmian's R&D Headquarters in Italy, P-Laser technology is eco-sustainable. The HPTE insulating system of P-Laser cables uses thermoplastic materials unlike traditional XLPE cables with cross-linked polyethylene insulation. The metal used for the conductor and the outer cable screens under the protective sheath is also recyclable, making the cable 100% eco-friendly. From the efficiency point of view, P-Laser technology allows grid operators to work at temperatures above the typical 90°C as usual with XLPE traditional technology. This higher thermal performance allows them to increase the power transmission for the same conductor section, or a longer cable life at the same temperature, but above all it allows higher capability. This is particularly important in the event of emergencies, grid congestion and "N-1" conditions (disconnection because of malfunction or maintenance of an adjacent line)."

"The IEA estimates that of all efforts required to deliver a 50% reduction in global emissions by 2050 24% will need to come from end use fuel efficiency, 12% has to come from end use electricity efficiency and a further 7% will need to come from power generation efficiency. There is substantial potential for improving thermal efficiency of Europe's power plants. Our coal plants operate at an average 38% (BAT - Best Available Technology - on new coal plants delivers 46%). Our gas plants operate at an average of 52% efficiency (BAT- Best Available Technology - on new gas plants delivers more than 60%). Due to the age of the installed base, the average efficiency of Chinese coal plants is now higher than in Europe."

A vote could come as early as this week in the U.S. Senate on a bill introduced by Senate Tax Committee Chairman Max Baucus (D-MT) and Senate Majority Leader Harry Reid (D-NV) containing a one-year renewable energy production tax credit (PTC) extension and a small wind turbine investment tax credit. The Senate bill, S. 3335, contains a one-year PTC extension at its current value. After December 31, 2009, any further extension would include the "presumption" of a cost cap, which would, through a complex formula, put a ceiling on the value of the credits of no greater than 35% of project value. The small wind ITC has a cap of US $4,000 per system.The 10-year cost for the PTC, including all technologies to which it applies, is projected to be approximately US $7 billion, while the ITC, which includes solar, would cost approximately US $907 million over 10 years. The bill also includes provisions to extend through 2014 the tax credits for solar energy, fuel cell and microturbine property, as well as the residential energy efficient property tax credit. Marine renewable energies could also benefit from the bill as credits to build wave, tidal, current and ocean thermal energy conversion systems of at least 150 kilowatts (kW) are extended through the end of 2011.

Long ago, the industry determined that the combination of copper tubing and aluminum fins provided the most efficient transfer of thermal heat in condenser coils. Manufacturers of residential units are not necessarily on that same page - or that line of thinking - today. Most manufacturers, if not all, are revising, have revised, or continue to revise their outdoor coil construction. One of the main objectives, of course, is to increase heat transfer efficiency, as energy efficiency is high on every homeowner's wish list. In the end, each manufacturer believes it has engineered and/or perfected - at least up to now - the most-efficient coil design. Some, like Goodman Manufacturing, have made changes as a direct result of the efficiency offered from R-410A refrigerant.

This evolution made sense at first, because power stations were costlier and less reliable than the grid, so by backing each other up through the grid and melding customers' diverse loads, they could save capacity and achieve reliability. But these assumptions have reversed: central thermal power plants now cost less than the grid, and are so reliable that about 98 percent to 99 percent of all power failures originate in the grid. Thus the original architecture is raising, not lowering, costs and failure rates: cheap and reliable power must now be made at or near customers.

Nano-graphene platelets (NGPs) have high Young's modulus, high thermal conductivity (five times that of copper), electrical conductivity similar to copper, and are said to be 50 times stronger than steel.\n

It describes a new design to help concentrated solar power (CSP) increase efficiency and reduce cost.

Super strong nanometals - a Chinese-Danish success Research shows that it is possible to produce copper about 4 times stronger than commercial material - and doing so while also having a ductile material. As the thermal and electrical conductivity are also good, the manufacturing of, for example, electrical conductors with improved mechanical properties looks promising
