Gas Turbine Technology: Picking up bad vibrations
To enhance power generation performance, the development of modern gas turbines focuses on realizing higher turbine inlet temperature and lower nitrogen derivative emissions.
Cogeneration: CHP fuels chemical reactions
Rising living standards in many parts of the world mean rising energy consumption and carbon dioxide (CO2) emissions.
Operation & Maintenance: Transforming plant asset management
Meridian Energy is New Zealand’s largest state-owned renewable energy electricity generator, providing approximately 30 per cent of the country’s total generation.
Emissions Control: Modelling ESP performance enhancements
For particulate pollution control, most coal fired generators are fitted with electrostatic precipitators (ESP), the operational performance of which can be compromised by the firing of low sulphur, high ash coals of countries like India and China or high moisture, low sulphur from the Western USA, resulting in emissions well in excess of the host countries’ legislation.
NUCLEAR POWER: Adopting a nuclear family
Misleading, seriously flawed and procedurally unfair,” were the damning words used by a High Court judge just two months ago to describe the British government’s plans to clear the path for construction of a new generation of nuclear power plants.
International
According to figures released by Point Carbon, the international carbon market will see over 4.2bn tonnes of carbon dioxide equivalent (CO2e) traded in 2007, which is worth around € 23.6bn ($34.1bn).
Europe
The UK has become the first country to propose legislation setting binding limits on greenhouse gas emissions as it stepped up its campaign for a new global warming pact to succeed the Kyoto Protocol.
Asia-pacific
China is expected to add 3 GW of wind power capacity between 2006-2010, as part of the government’s plan to generate more electricity from clean energy sources.
Americas
Brazilian power generator Tractebel Energia, a unit of Suez Energy, plans to invest 516m reais ($248m) this year.
Companies
French nuclear energy firm Areva has raised its bid for Repower to €140 ($186) per share, beating India’s Suzlon Energy’s bid and securing a 30 per cent stake in the German wind turbine maker.
EU energy policy: fact or fiction?
The key agreements from last month’s intensive two-day European Union (EU) summit are nothing if not ambitious.
Don’t coal it a comeback
Coal fired power plants are at the forefront of technological advances and will have a more important role in reducing global carbon emissions than renewable sources, writes Tim Probert.
Genset Roundup
Wärtsilä Corporation has introduced the PowerCubes to provide industrial customers, utilities and independent power producers with small power plants based on one to three generating sets.
Equipment Roundup
Insulation tester maker Megger has launched the S1-554 and S1-1054 high-voltage insulation testers suitable for use in noisy electrical environments like substation switchyards.
