Carbon dioxide capture and geological storage is a technology that could be used to reduce carbon dioxide emissions to the atmosphere from large industrial installations such as fossil fuel-fired power stations by 80-90%. It involves the capture of carbon dioxide at a large industrial plant, its transport to a geological storage site and its long-term isolation in a geological storage reservoir...

The emissions of carbon dioxide and nitrogen and sulphur oxides for electricity generation with coal and biomass co-firing are investigated and the furnace gas temperature assessed. The study uses simulation and considers fuel combinations based on two coals (bituminous coal, lignite) and four types of biomass (rice husk, sawdust, chicken litter, refused derived fuel). With increasing biomass, ...

If the United States were to adopt a policy to phase out nuclear generation, as has happened recently in other developed countries, what would the environmental and energy-mix implications be? Based on alternative scenarios of nuclear exit that consider the influence of potential policies to limit greenhouse gas emissions, a model of the US and global economy indicates that, under current polic...

Air pollution measurements during April 1991 are reported from the Craeybeckx highway tunnel in Antwerp, Belgium. The tunnel was used daily by an average of 45,000 vehicles, of which 60% were gasoline fueled passenger cars, 20% diesel cars, and 20% trucks. Of the gasoline cars, only 3% had three-way catalysts. Tunnel air concentrations of nitrogen oxides, sulphur dioxide, carbon dioxide, carbon...

Vehicle Emission is one of the main causes of environmental damage. Vehicle engines produce carbon dioxide (CO2), hydrocarbon (HC), Nitrogen oxides (NOx) and many other harmful substances. An investigation was conducted using a compression-ignition engine fuelled with different ratios of blends of diesel and biodiesel at different EGR rates. The effects of different ratios of fuel blends and EG...

Anthropogenic deforestation in tropical countries is responsible for a significant part of global carbon dioxide emissions in the atmosphere. To plan efficient climate change mitigation programs (such as REDD+, Reducing Emissions from Deforestation and forest Degradation), reliable forecasts of deforestation and carbon dioxide emissions are necessary. Although population density has been recogn...

optimal sitting and sizing of shunt capacitor banks at the distribution networks for the purpose of power quality improvement is drawn much attention of electric power utilities in the last decades. determining the optimal number, location and sizing of capacitor using bee colony optimization algorithm (bco) is being presented in this paper. the bco algorithm is a new population based meta-heur...

This paper studies the impact of cross-border Mergers and Acquisitions (M&As) on Carbon Dioxide emissions. Carbon Dioxide is the main anthropogenic greenhouse gas. A global problem that requires a multilateral solution. To take this into account we introduce an institutional variable, which captures the degree of international commitment to decrease and control the degradation of the environmen...

[1] Numerical studies have indicated that the steady‐state ocean‐atmosphere partitioning of carbon will change profoundly as emissions continue. In particular, the globally averaged Revelle buffer factor will first increase and then decrease at higher emissions. Furthermore, atmospheric carbon will initially grow exponentially with emission size, after which it will depend linearly on emissions...

Ecological aspects of coal combustion utilization of CO2 from flue gas Slovakia belongs to the group of twenty worst polluters throughout the world, releasing 10 12 tons of carbon dioxide per capita, whereas the worldwide average value is about 5 tons. It is known that the big electric and thermal power stations produce only 25 % of the overall production of carbon dioxide in Slovakia, whereas ...
