Efficiency analysis of coal-based thermal power generation in India during post-reform era
Coal-based thermal power stations are the leaders in electricity generation in India. This study employs the stochastic frontier production function methodology for panel data to measure the technical efficiency (TE) of coal-based thermal power plants in India during 1994-1995 to 2001-2002. Efficiency varies widely across plants and regions, while the TE is time-invariant. The average TE is ...

Implications for UK coal-fired power stations of a move to a particulate matter standard based on PM2.5
The contribution of UK coal-fired power stations to ambient PM2.5 concentrations has been assessed using short- and long-range modelling. The results suggested a minimal contribution from power stations to both local and regional concentrations of PM2.5 relative to the standards in the proposed European Directive on Ambient Air Quality and only a modest contribution in terms of overall UK PM2.5 ...

World Bank to shift its global investment policy
As part of a major energy strategy, the World Bank is planning to cut funding for fossil fuel plants and focus on renewables. The World Bank is planning to cut funding for fossil fuel plants and emphasise the benefits of renewables as part of a major energy strategy. The news suggest a major shift in the bank’s approach to green investment, and comes just days after the organisation ...

Cenospheres - Case Study
The problem: A cenosphere is a lightweight, inert, hollow sphere made largely of silica and alumina and filled with air or inert gas, typically produced as a byproduct of coal combustion at thermal power plants. On average 0.5% of the fly ash generated in a coal fired power station boiler are Cenospheres. When fly ash is wet discharged in to ash ponds/lagoons cenospheres float on the water ...

Thermo-economic efficiency of low capacity coal-based power plants
The method of estimation of thermo-economic factors, allowing the justification of the construction of low capacity coal-based power plants has been developed in the present paper. The C-curve method applied for thermo-economic analysis is used here for determination of the optimal ratio between specific exergetic and cost-performance factors. The results of the analysis show that for coal-based ...

Methylmercury in mosquitoes around a large coal‐fired power plant in Central Ohio
Emissions from coal‐fired power plants are the major anthropogenic source of mercury (Hg) in the environment. Because emitted Hg can be deposited near the source, concerns arise about the effects of coal‐burning facilities on levels of toxic methylmercury (MeHg) in biota near such sources. We investigated the potential impact of a large Hg‐emitting (450 kg in 2005) coal‐fired power station in ...

Disposal of saline wastewater from electrical power plants
Saline wastewater from a coal-fired Utah Power Plant has been applied in central Utah, USA, since 1987, to irrigate various agricultural crops. The primary goals of this research: to dispose of saline wastewater by maximising actual evapotranspiration (ETa) and to prevent contamination of surface and groundwater by eliminating runoff and throughout the years (1987-2005). Plots were established ...

Modelling food web structure and selenium biomagnification in Lake Macquarie, NSW‐ Australia, using stable carbon and nitrogen isotopes
As a consequence of coal‐fired power station operations, elevated selenium concentrations have been reported in the sediments and biota of Lake Macquarie (NSW, Australia). In the present study, we applied an ecosystem‐scale model to determine how selenium in a seagrass food web is processed from sediments and water through diet to predators, using stable isotopes (δ13C and δ 15N) to establish ...

Technical and economic studies on the optimisation of prospective coal-fired power stations
The paper considers problems of choosing rational parameters of thermal power plants on fossil fuel. A technique for comparison of the energy and economic efficiency of prospective coal-fired power plants is described. The optimisation results of parameters of combined-cycle plants with coal gasification at low and high-temperature levels and steam turbine plants on supercritical steam parameters ...

Policy uncertainty puts UK at risk of missing carbon targets
New report warns the government must set a clear policy direction to attract the investment needed for a low carbon economy. Recurrent policy uncertainty could mean the UK fails to attract the estimated £150bn of investment needed to build a low carbon infrastructure over the next 20 years. This is the conclusion published in a new survey today by the CBI and Accenture entitled: ...

Over 170 Non-State Actors Have 80-100% Climate Commitments
A report by CDP and The Climate Group reveals that over 170 major companies, states, regions, and cities around the world have committed to reducing their greenhouse gas (GHG) emissions by 80-100%, or procuring 100% of their power from renewable sources. The findings reveal a trend toward increasingly ambitious climate action on the part of “non-state” actors (for example, ...

CSP industry gears up ‘to take advantage’ of new opportunities
The recent announcement of the Environmental Protection Agency’s proposed new carbon emission standard for future coal-fired power stations has given the CSP industry yet another huge boost in the fight for an established place in the US energy market, through the use of hybrid CSP plants. This is just one example of the new opportunities this innovative industry is able to take advantage ...

Case study - Fort Mandan visitor services center
The North Dakota Lewis & Clark Bicentennial Foundation has created a unique facility for one of the most vital sites on the Lewis & Clark Trail. The new visitor services center at Fort Mandan stands as a showcase for coal combustion products, while at the same time educating visitors about the journey of Lewis & Clark in North Dakota. Three major parts of the North Dakota: economy, ...

Developing Decentralised Distributed Generation in Africa
Many countries in the developed world created power generation networks based upon large centralised power generation stations with significant investment in power transmission and distribution networks. From the African context this has not happened yet there is a huge need to increase power generation capacity. The thought of addressing this through a small number of large gas, hydro, coal or ...

Legacy energy infrastructure: The hidden threat to our climate
It’s easy to identify the biggest climate threats: coal and oil-fired power stations pouring emissions into the atmosphere, heavy industry smoking up the sky, and the seemingly endless traffic jams of petrol and diesel polluting vehicles. But another enemy is standing in the way of a greener future; one rarely mentioned because it’s effectively invisible: our legacy energy ...

Power plants coordination for economic and environmental load dispatch of thermal power plants with wind generation systems
Economic load dispatch (ELD) and economic emission dispatch (EED) have been applied to obtain generation scheduling of thermal power plants at optimum fuel cost and emissions. Due to limited availability of quality coal, issue of environmental emissions and high prices of coal, installation of renewable energy systems are suggested in power grid. Renewable energy system preferably wind generators ...

Experience on coal reburn in a utility boiler
Reburning is an in-furnace combustion modification technology for the reduction of NOx. By staging the introduction of the fuel, an environment is created where NOx generated by the combustion of the main fuel supply is subsequently consumed by the hydrocarbon radicals arising from the reburn fuel under reducing conditions. ENEL has retrofitted unit No. 4 of Vado Ligure power station with ...
