EGEE 101 EXAM 3 TERMS WITH
DEFINITIONS
emission trading - Correct Answer✔️✔️-bringing new parts to less efficient countries to increase
efficiency. it is paid for and then claimed for credit of emission reduction.
biomass - Correct Answer✔️✔️-replanting forests to offset Carbon sinking. advantages: increased
employment, increased security of energy, increased fossil fuel lifetime, net carbon dioxide neutral,
less pollution.
methane - Correct Answer✔️✔️-contributes to increased concentration in atmosphere. capture the
methane for use instead of allowing leaks. livestock and landfills contribute the most leakage.
sequestration - Correct Answer✔️✔️-locking away CO2 to keep it from entering the atmosphere.
storage of CO2: ocean, minerals, depleted oil and gas wells, brine fields, coal fields, carbon sinks.
power plants: air mixed with nitrogen... we want the oxygen but it's costly to separate.
sequestration: the ocean - Correct Answer✔️✔️-need more plankton to fertilize and trap CO2 as
they decay for carbon cycle. this is a carbon sink, there's more carbon in the ocean than in the
atmosphere.

, 3 processes of ocean sequestration - Correct Answer✔️✔️-1. carbon sink through fertilization 2.
inject CO2 into ocean to form hydrates 3. inject CO2 into bottom of ocean to form CO2
underwater lake.
sequestration: oil fields - Correct Answer✔️✔️-small holes in oil fields can be filled with CO2. if
the field is still producing the gas aids in extraction of crude through pressure. otherwise cap the
methane leaks.
sequestration: brine fields - Correct Answer✔️✔️-saline formations. estimated saline storage
capacity in the US is large and most existing CO2 point sources are within easy access to a saline
injection point. Sleipner West Heimdel gas reservoir of the Norwegian oil company Statoil is the
only commercial CO2 geological sequestration facility.
sequestration: coal - Correct Answer✔️✔️-large cracks and pores in coal allows permeability. CO2
is attracted to the coal micropore and doesn't need much space to bounce around, it wants to
associate so we can fill more volume than we could with empty space. kicks out methane too,
sequester coal, collect methane. cost is slightly high and would increase the cost of electricity.
conservation - Correct Answer✔️✔️-if we conserve, we use less, if we use less, we pollute less.
reduction - Correct Answer✔️✔️-achieved through economic depression, kind weather.
reducing N2O - Correct Answer✔️✔️-NOx consists of NO N2O and NO2. N2O is the
greenhouse gas of the three. solutions include: NOx removal (acid deposition), mitigation,
prevention are applicable to N2O.
