BiomethaneGaseous renewable energy source derived from agricultural biomass (dedicated crops, by-products and agricultural waste and animal waste), agro-industrial (waste from the food processing chain) and the Organic Fraction Municipal Solid Waste (OFMSW).

Carbon budgetThis is the amount of carbon dioxide the world can emit while still having a likely chance of limiting average global temperature rise to 1.5°C above pre-industrial levels, an internationally agreed-upon target.
CBACost Benefit Analysis carried out to define to what extent a project is worthwhile from a social perspective.
CCSCarbon Capture and Storage. Process of sequestrating CO2 and storing it in such a way that it won’t enter the atmosphere.
CHPCombined heat and power
COP21Legally binding international treaty on climate change, adopted by 196 Parties at COP 21 in Paris on 12 December 2015. In this report it also refers to the COP21 scenario building approach which enables full energy scenario development and carbon emission assessment
Direct electrificationElectricity demand for direct use in the final demand sectors (residential, tertiary, industry etc). Electricity which is converted to other energy carriers through power to gas or power to liquids is referred to as indirect electrification.
DSRDemand Side Response. Consumers have an active role in the balancing of energy supply and demand by changing their energy consumption according to the energy price and availability. For example, by softening demand peaks in case of congestions, or by increasing energy use during surplus supply.

LTSLong Term Strategy released by the European Commission on 28 November 2018: A Clean Planet for all. A European strategic long-term vision for a prosperous, modern, competitive and climate neutral economy.
LULUCFLand Use, Land Use Change and Forestry. Sink of CO2 made possible by the fact that atmospheric CO2 can accumulate as carbon in vegetation and soils in terrestrial ecosystems.
NECPsNational Energy and Climate Plans are the new framework within which EU Member States have to plan, in an integrated manner, their climate and energy objectives, targets, policies and measures to the European Commission. Countries will have to develop NECPs on a ten-year rolling basis, with an update halfway through the implementation period. The NECPs covering the first period from 2021 to 2030 will have to ensure that the Union’s 2030 targets for greenhouse gas emission reductions, renewable energy, energy efficiency and electricity interconnection are met.

P2GPower to gas. Technology that uses electricity to produce hydrogen (Power to Hydrogen – P2H2) by splitting water into oxygen and hydrogen (electrolysis). The hydrogen produced can then either be used directly or indirectly to produce other fuels, where it is combined with CO2 to obtain synthetic methane (Power to Methane – P2CH4) or can be converted to other energy carriers like for example synthetic ammonia (P2NH3).
P2LPower to liquids. Combination of hydrogen from electrolysis and Fischer-Tropsch process to obtain synthetic liquid fuels.
PCIProject of Common Interest
Power-to-Hydrogen/P2HydrogenHydrogen obtained from P2H2
Power-to-Methane/P2MethaneRenewable methane, could be biomethane or synthetic methane produced by renewable energy sources only.
RESRenewable energy source
SMRSteam methane reforming, an industrial process to produce hydrogen with natural gas. Can be outfitted with carbon capture technologies
Synthetic fuelFuel (gas or liquid) that is produces from renewable or low carbon electrical energy.
