  • Future plans for energy production in the European Union as well as other locations call for a high penetration of renewable technologies (20% by 2020, and higher after 2020). The remaining energy requirements will be met by fossil fuels and nuclear energy. Smaller, less-capital intensive nuclear reactors are emerging as an alternative to fossil fuel and large nuclear systems. Approximately 50 small (<300 MWe) to medium-sized (<700 MWe) reactors (SMRs) concepts are being pursued for use in electricity and cogeneration (combined heat and power) markets. However, many of the SMRs are at the early design stage and full data needed for economic analysis or market assessment is not yet available. Therefore, the purpose of this study is to develop “target cost” estimates for reactors deployed in a range of competitive market situations (electricity prices ranging from 45–150 €/MWh). Parametric analysis was used to develop a cost breakdown for reactors that can compete against future natural gas and coal (with/without carbon capture) and large nuclear systems. Sensitivity analysis was performed to understand the impacts on competitiveness from key cost variables. This study suggests that SMRs may effectively compete in future electricity markets if their capital costs are controlled, favorable financing is obtained, and reactor capacity factors match those of current light water reactors. This methodology can be extended to cogeneration markets supporting a range of process heat applications.

  • This year, the European Business Summit's theme is "Greening the Economy". However, instead of inviting companies that are pioneers in environmental technologies, the programme boasts some of the most polluting companies in the world and some of the worst performers in their sector. Instead of green leaders, the EBS presents dirty laggards. With an action and exhibition at the opening of the European Business Summit, Friends of the Earth Europe exposed the greenwashing practices of the businesses taking part.

  • we put so much focus on new power generation, arguably a more sexy topic when we talk about wind and solar, and seem to forget that maximizing renewable output means improving the way the grid operates and expanding its reach.
  • Colin Bennett on 20 Feb 08
     
    Electrical grids worldwide vary in age and range, but overrall, electrical grid systems are seen as requiring urgent upgrades to meet growing demand. Of course, items such as transformers and power lines are maintained and upgraded by utility companies. However, utitility companies must feel confident about long-term financial terms as well as increasing demand in order to invest. With a now sensitive economy, and perhaps a looming world recession, utility companies are hesitatnt to invest. With, for example, large transformers being ordered years in advance, delaying decisions to invest for too long may lead to a less well performing grid.

  • natural gas is okay but it's not ideal. It still emits greenhouse gases and NOx. It's also becoming more volatile and is likely to become much more expensive over the coming years. Also, the power mix in Ontario will become cleaner over the next decade -- no coal, more nuclear, hydroelectric, wind and natural gas. So there's an argument that heating your home with electricity could be cleaner than using natural gas, if you can do it efficiently -- in other words, if you can find a better way than using resistance heating.
  • a 34-year-old engineer who was a cryogenics expert with the U.S. Navy, realized that conventional air-source heat pumps that are popular in the U.S. south do not perform well in cold climates and are therefore not economical. So he went ahead and built his own, called Acadia, and it can operate efficiently down to minus 30 degrees C.

  • Neuwing Energy Ventures, a New York-based marketer of energy-efficiency certificates, would perform an initial assessment of IBM customers' sprawling data centers -- the massive, air-conditioned facilities that store information and route anything from eBay purchases to e-mail. IBM would identify potential energy savings areas for its clients, and Neuwing would grant the IT firms certificates for the total megawatt-hours no longer needed to cool or operate the data center equipment. Each certificate would equal 1 megawatt-hour (MWh) per annum, said Rich Lechner, IBM's vice president for IT optimization. Clients could sell the certificates to utilities subject to state renewable portfolio standards, as well as sell to other companies that aim to reduce their carbon footprint through energy savings. The value of the energy efficiency certificates, historically in the $2-$10 range, is determined by the supply and demand for those certificates in each trading market.

    Nice idea, but has it got performance potential? Rotary engine impressively compact and friction free. How much emission is generated by the compression of the air? Is it just passing the emissions on to a power station?

  • Xtreme Energetics has investigated the possibility of using mechanical trackers to perform the same light-focusing duties as other solar array manufacturers have. However, HP’s transparent transistor can do the job electronically, rather than mechanically, and significantly reduce the costs of such an installation. Such a solar array is known as a concentrating photovoltaic (or CPV) solar array. To date, CPV arrays are fairly expensive and cannot store energy, making them less useful. They also work best in specific sections of the world — those with the highest levels of solar radiation, such as the southwest United States and northern Africa.

    What [the survey] found was that while respondents expressed concern about their environmental impact, few were willing to smother those concerns with cash. And, in fact, the numbers willing to take a hit to their wallets or to their server performance in order to reduce their carbon footprints were actually lower this year than when the survey was first conducted in 2007.

  • The ultracapacitor-equipped Toyota Supra HV-R coupe became the first hybrid to win the 24-hour endurance car race held at Japan’s Tokachi International Speedway. The hybrid Supra finished 616 laps of the 5.1-kilometer (roughly three-mile) course—19 more laps than the second-place, non-hybrid, Nissan Fairlady Z.
