1. COAL POWER GENERATION Steam coal, also known as thermal coal, is used in power stations to generate electricity. Coal is first milled to a fine powder, which increases the surface area and allows it to burn more quickly. In these pulverized coal combustion (PCC) systems, the powdered coal is blown into the combustion

The achieved international consensus on the °C target entails that most of current fossil fuel reserves must remain unburned. A major contribution has to come from coal as both the most abundant and the most emissionintensive fuel. Currently, a majority of climate policies aiming at reducing coal consumption are directed towards the demand side. In the absence of a global carbon ...

Hydrogen production is the family of industrial methods for generating hydrogen gas. There are four main sources for the commercial production of hydrogen: natural gas, oil, coal, and electrolysis of water; which account for 48%, 30%, 18% and 4% of the world's hydrogen production respectively. Fossil fuels are the dominant source of industrial hydrogen.

Activated charcoal is a fine, odorless, black powder. It is produced by heating charcoal to an extremely high temperature in an environment without oxygen, such as a tank. Once activated, the powder's pores trap chemicals, making it effective at treating overdoses and chemical poisonings by preventing the body from absorbing the toxic substances.
