Q

Fracking

A

a technique to stimulate production of oil and gas after a well has been drilled. It involves horizontal drilling and the injection of a mixture of water, sand and chemicals into the well under high pressure to create small cracks within the formation, which will release the gas/oil.

Q

Stranded gas

A

gas that is not considered economically exploitable, hence it is gas that is essentially wasted or unused. It can be for example gas at a remote location, and because of high infrastructure costs it is not used.

Q

CNG

A

compressed natural gas: natural gas compressed to a pressure at or above 200-248 bar. It is used as a fuel for NG powered vehicles.

Q

Coal-to-Gas Switching

A

Switching coal powered plants to NG enables instantaneous adjustments in the merit order due to the cheaper variable production costs of gas.

Q

Micro-Grid

A

small grid connecting few households or a village. This operates independently from the grid, often in combination with renewable energy sources.

16
Q

Diesel Genset:

A

Diesel generators mainly used in rural areas to provide electricity

17
Q

Leapfrogging

A

Leaving out stages of economic development. Later stage economic development may require less energy and lower capital requirements of industrialization.

18
Q

Climate Change

A

change in statistical distribution of weather patterns when that change lasts for an extended period of time

19
Q

Fugitive Emissions

A

emissions of gases from pressurized equipment due to leaks and other unintended releases, mostly from industrial activity.

20
Q

Cap and Trade

A

a market based approach to control pollution by providing economic incentives for achieving reductions in the of emissions of pollutants Cap and trade is a policy approach for controlling large amounts of emissions from a group of sources. The approach first sets an overall cap, or maximum amount of emissions per compliance period, for all sources under the program. Allowance trading enables sources to design their own compliance strategy based on their individual circumstances while still achieving the overall emissions reductions required by the cap

21
Q

Kyoto Protocol

A

includes last binding targets within the UNFCC framework. Allocation based on historic emissions, excluded US ad developing countries

22
Q

Bio-Char

A

name of charcoal when used as soil amendment.
It uses a variety of organic feedstocks to get energy, sequestered carbon, and fertilizer value streams. Improves soil functions and reduces emissions from biomass that would otherwise naturally degrade to GHGs.

23
Q

Energy intensity

A

a measure of energy efficiency of a nation’s economy. E/GDP

24
Q

Stove efficiency

A

measure of efficiency for cook stoves in developing countries.

25
Q

Climate Development Mechanism (CDM)

A

The Clean Development Mechanism (CDM), defined in Article 12 of the Protocol, allows a country with an emission-reduction or emission-limitation commitment under the Kyoto Protocol (Annex B Party) to implement an emission-reduction project in developing countries. Such projects can earn saleable certified emission reduction (CER) credits, each equivalent to one tonne of CO2, which can be counted towards meeting Kyoto targets.

26
Q

Social cost of carbon

A

negative externalities from carbon emissions, like cost of climate change.

27
Q

Abatement Cost

A

additional cost (or net benefit) of replacing a technology in the Bau scenario by a low carbon alternative, measured in EUR/tCO2 abated emissions

28
Q

Abatement Curve

A

Visual compilation of abatement potentials an costs sorted by increasing abatement costs

29
Q

Parasitic Energy Requirements

A

requirements for power consumed even when the devices are shut off -> standby power.
