Greenpeace is an independent global campaigning organization that acts to change attitudes and behavior, to protect and conserve the environment and to promote peace by catalyzing an energy revolution to address the number one threat they believe is facing our planet: climate change and deal with other environmental concerns

The requirement for ‘good prospect’ originates from the approved code of practice in relation to the 1995 Prevention of Fire, Explosion and Emergency Response (PFEER) regulations issued by the UK Government. These regulations in conjunction with the Manning and Administration Regulations (MAR) and Design and Construction Regulations (DCR) are the key pieces of legislation that implement the findings and recommendations of Lord Cullen, who presided over the Piper Alpha Disaster inquiry. ‘Good prospect’ equates to the ability to rescue personnel from the sea and recover them to a place of safety, in all but the most severe of weather conditions, within prescribed survival time limits. Traditionally, this work has been undertaken by SSVs (standby safety vessels) or a mixture of SSVs and helicopters. The critical issue is how long a person can survive at sea (e.g. the north sea) after escaping from a rig >

Gases such as water vapor, carbon dioxide, nitrous oxide and methane that are transparent to solar radiation but opaque to longwave radiation. Their action is similar to that of a glass in a greenhouse

GasPro is the largest company in Israel that deals in alternative fuel systems for cars

Gasoline which is obtained directly from crude oil by fractional distillation. Straight-run gasoline generally must be upgraded to meet current motor fuel specifications. Its important characteristics include its octane number (Ron, Mon), oxygenated/non-oxygenated, vapor pressure (RVP) – summer and winter, its sulfur content, aromates, olefines, etc.

Gasification is a thermo-chemical process that breaks down coal – or virtually any carbon-based feedstock – into its basic chemical constituents. In a modern gasifier, coal is typically exposed to steam and carefully controlled amounts of air or oxygen under high temperatures and pressures. Under these conditions, molecules in coal break apart, initiating chemical reactions that typically produce a mixture of carbon monoxide, hydrogen and other gaseous compounds. The environmental benefits of gasification stem from the capability to achieve extremely low SOx, NOx and particulate emissions from burning coal-derived gases. Sulfur in coal, for example, is converted to hydrogen sulfide and can be captured by processes presently used in the chemical industry. Coal gasification may offer a further environmental advantage in addressing concerns over the atmospheric buildup of greenhouse gases, such as carbon dioxide. If oxygen is used in a coal gasifier instead of air, carbon dioxide is emitted as a concentrated gas stream in syngas at high pressure. In this form, it can be captured and sequestered more easily and at lower costs. By contrast, when coal burns or is reacted in air, 79 percent of which is nitrogen, the resulting carbon dioxide is diluted and more costly to separate. Gasification of fossil fuel is widely used for the generation of electricity but almost any type of organic material can be used as the raw material for gasification and it can be an important technology for renewable energy.
