Computational Fluid Dynamics - Spray modelling makes a splash
The combustion of sulphurous fuels leads to high sulphur dioxide (SO2) emissions.
Waste to Energy - Energy: no time to waste
Waste to Energy (WtE) plants thermally treat household waste and waste similar to household waste that is not otherwise reusable or recyclable, and generate electricity and heat from it, which is delivered to homes and industry.
Clean coal technologies: mitigating the future
Approximately 26 gigatonnes (Gt) of carbon dioxide (CO2) are annually emitted from existing fossil fuel sources worldwide.
Renewable Energy - Europe takes aim at 2020 renewables target
It a time when virtually every human activity is judged according to its impact on climate change, it came as no surprise in March when European Union (EU) political leaders voted to set a firm goal for sustainable energy across the member states.
Distributed Generation - Waste not, want not
Steel production processes typically dispose large volumes of coke gas and other speciality gases that, until recently, had been mainly used to produce steam in gas fired boilers.
Plant Procurement - To EPC or not to EPC?
The term EPC stands for ‘Engineer, Procure and Construct’.
Solar Power - Ultility-scale sun power
Unlike photovoltaics, which generate electricity directly from sunlight, concentrating solar power (CSP) technologies use heat to generate electricity in much the same way as a conventional thermal power station.
IT Focus - Metering out change
Energy supply has become a fundamental challenge for all energy providers in recent years.
Nanotechnology - The mighty atom
The UK Government’s Energy Review of 2006, which declared a long-term sustainable approach to supplying the UK’s power supply, devoted just two of its 218 pages to the importance of innovative new technologies.
Wind Power - Wind, a match for fossil fuels
If prices of energy from conventional and sustainable sources are to be compared on equal terms, it is essential to examine all aspects of the calculation, including, for example, the environmental costs attributable to carbon dioxide (CO2) emissions.
Gensets - Setting genset exhaust emissions standards
As more stringent diesel engine emissions standards are introduced, they present significant challenges to engine manufacturers.
IT Focus - Real-time for a change?
The aim of every business is to maximize shareholder value; in the power industry this is achieved through operating reliable plant safely and efficiently.
Emissions Control - Beating the directive blues
Wholesale replacement of outdated equipment to meet emissions regulation is often not an option because of cost and lengthy downtimes (meaning loss of earnings on top of the additional cost), so many site managers are now looking to emissions control specialists to help them achieve compliance without having to resort to major component replacement.
Biomass - Biomass gears up for growth
The combustion of biomass holds a number of significant advantages over other types of renewable generation, chiefly its predictable and reliable nature.
IWPP Financing - Cashing in on Middle Eastern power and water
Driven by high oil prices and the increasing global demand for oil, natural gas and their derivative products, the governments of the Middle East, and especially the states of the Gulf Cooperation Council (GCC) - Saudi Arabia, UAE, Kuwait, Qatar, Oman and Bahrain, are looking to capitalize massively on the investment and development opportunities arising from their large fiscal and external account surpluses in recent years.
Steam Turbines - Measuring up for shaft growth
One of the challenges facing instrumentation engineers in the power generation sector is the accurate measurement of shaft growth relative to casing on large steam turbines.
Emission Trading - Can the carbon market drive investment decisions?
The scale of the challenge facing Europe in reducing its emissions is considerable.
Power Plant Siting - Ensuring power projects’ have green credentials
While the roots of environmental awareness can be traced back several hundred years, it wasn’t until the 1960s in the United States that the environmental movement began to gain significant momentum.
Solar Power - Sunlight powering the desert
The word ‘vast’ is inadequate to describe Nevada’s desert.
On-Site Power - On golden sands
With the largest mineral resources of any country in the Gulf region, Saudi Arabia is a land rich in gold and other precious metals, as well as crude oil.
Secure, competitive energy - A “new path” in a carbon-constrained world
There is now overwhelming evidence that emissions of greenhouse gases (GHGs) are contributing to a worrying shift in the global climate and that they will have to be very substantially reduced in the coming decades.
LATIN AMERICA - Conquistadors return
Spanish companies have always shown interest in doing business in what was once the most important part of their short-lived, but prosperous empire.
Power briefing: Spain
Spain has the fifth largest electricity market in Europe, and over the next few years merger and acquisition activity as well as direct energy investmentares are expected to dominate.

PEI’s Guide to Madrid
Madrid Visitor Guide
China’s carbon leap forward?
China could overtake the United States as the world’s biggest emitter of greenhouse gases this year or next year.
Papering over the cracks?
Tim Probert examines whether the United Kingdom has finally laid the groundwork for hitting its ambitious renewable energy targets with the recent release of the energy policy ‘White Paper’.
INTERNATIONAL
Iran has invited bids for a contract to build two more nuclear power plants at its site in Bushehr, in the south of the country.
EUROPE
Despite attending two energy summits Germany has not answered questions over its future energy security, Harry Roels, outgoing chief executive of utiliy giant RWE, has complained.
ASIA-PACIFIC
A fifth attempt is to be made to find a buyer for the National Transmission Corp, the Philippines’s high voltage network owner and operator.
AMERICAS
The uncertainty surrounding potential limits on carbon dioxide emissions has caused “paralysis and indecision” in the US power industry and has severely hampered efforts to build new coal fired power stations, according to NRG Energy president and CEO David Crane.
COMPANIES
Electricity and gas network operators National Grid is to invest more than $3bn in its US networks over the five years from 2006 to 2011, in addition to existing maintenance.
Genset Roundup
The diesel gensets market in Eastern Europe looks set to enjoy a positive future, while the Western European counterpart, which is fairly mature market, is approaching saturation.
Equipmment Roundup
LeT Systems’ eRespond Outage Management software suite has been included in Gartner’s Magic Quadrant market snapshot of Outage Management Systems [1H07 (1)], the company has announced.
