Glossary

The following is a list of terms and concepts from the Renewable Energy sector.

Bio-oil

Liquid fuel from vegetable or animal origin that can be used as fuels in cogeneration projects.

Biogas

Biofuel produced by the biological breakdown of organic matter such as biomass, in the absence of oxygen.

Biomass

Biological material, plant or animal matter, or biodegradable waste used as a fuel or energy source.

CHP

Combined Heat and Power

CHP Certificates

Certificates issued by local, regional or national authorities for the primary energy savings achieved by CHP facilities.

Cogeneration

A production of electricity and useful thermal energy simultaneously from a common fuel source (also combined heat and power, CHP).

Energo NV

The original name of Thenergo when it was founded in March 2002 in the form of a limited liability company.

Enro

German biomass-to-energy group in which Thenergo gained a controlling stake end of 2007.

Feedstock

Material that can be converted into another type of fuel or energy source.

Green certificate

Commodity in trading schemes proving that electricity was generated using renewable energy sources.

Green power

Energy derived from natural sources that replenish themselves over short periods of time including sun, wind, water and organic plant and waste material.

Greenhouse gases

Gases that trap the energy of the sun, thereby contributing to a rise in the earth’s surface temperature. Main exemples are carbon dioxide (fossil fuels burning by-product), methane and nitrous oxide.

Grid

Electric utility’s system to distribute power.

Jatropha oil

A non-edible vegetable oil produced from the processed seeds of the Asian Jatropha curcas plant and used as a fuel for energy generation in cogeneration units.

Leysen Group

An independent waste management and waste treatment business acquired by Thenergo Group in September 2007.

Manure

Organic matter used as fertiliser in agriculture. Animal manure is mostly made up of the feces of plant-eating mammals and poultry. Green manure is made up of crops grown for the express purpose of fertilising land.

Methane (CH4)

Principle component of natural gas and the simplest possible alkane. It is formed by the decomposition of organic landfill waste or by the fermentation of organic matter such as manure, wastewater sludge or any other biodegradable feedstock, under anaerobic conditions.

Municipal waste

Waste from residential, commercial and institutional sources.

Natural gas

A fossil fuel in the gaseous state and consisting primarily of methane.

Otto cycle engine

Combustion engine with a power cycle characterised by four strokes (intake/induction, compression, power and exhaust).

Polargen Benelux

A Benelux based developer and operator of CHP plants in the industrial greenhouse sector acquired by Thenergo in November 2007.

Rankine cycle engine

Steam engine based on a continuous thermodynamic cycle of liquid vaporisation and condensation to convert heat into energy.

Renewable Energy Sources (RES)

Sources which may be naturally replenished such as hydro power, biomass (solids, biofuels, landfill gas, sewage treatment plant gas, biodegradable waste, biogas) wind, solar power (photovoltaics/electric, thermal), geothermal, wave and tidal energy.

Solid Recovered Fuel (SRF)

Fuel prepared from non-hazardous waste which can be used for co-combustion in traditional coal-fired power plants or in other incineration processes.

Thenergo Power System (TPS)

Thenergo's system for central monitoring and controlling of its different decentralised CHP projects as if it were one centralised ‘virtual’ plant.

Twenty/Twenty initiative

The European Union’s proposal for a new directive on the promotion of Renewable Energy Sources, requiring its member states to achieve 20% renewable energy consumption by the year 2020.

Watt

Base unit of power in the metric system. 1 Watt is 1 Joule/second or the power developed in a circuit by a current of 1 ampere flowing through a potential difference of 1 Volt. 1 Megawatt (MW) = 1 million Watts or 1000 KW.

Woody Biomass

A high volume renewable energy source (wood, wood residue and by-products, and dedicated fast growing trees, bushes and shrubs) mainly used for local cogeneration.
