Biomass combustion and co-firing for electricty and heat Alholmens Kraft, Finland, the world's largest biomass-fired power plant

Combustion is the most common way of converting solid biomass fuels to energy. Worldwide, it already provides over 90% of the energy generated from biomass, a significant part of which in the form...

Community-based energy services © ClimateTechWiki and respective owners

Community based energy services, as the term suggests, provide heating, cooling and renewable energy to more than one building. It is an alternative to the use of individual energy related systems...

Concentrating Solar Power A solar collector assembly

Concentrating solar power (CSP) systems concentrate the energy from the sun for electricity production. This is done by heating a fluid which is then used to raise steam for a conventional...

Energy tower downdraft image energy tower downdraft

Energy towers are vertical, hollow towers constructed in dry desert regions with heights of 400 metres or more. Water from nearby sources (such as a sea) is pumped to the top of the tower and...

Ethanol Cook Stoves greengel stove

Alcohol burning stoves based on ethanol can be used for cooking, water heating and heating of buildings. The technology can be applied in households, institutions (e.g. schools) and...

Geothermal Electricity Production geothermal flash steam

Inside the Earth's crust there are several reservoirs with hot water which can be used for heating buildings and/or production of electricity. The process causes relatively little CO2...

Heat pumps for space heating or cooling and water heating © ClimateTechWiki and respective owners

Heat pumps deliver heating, cooling and hot water to buildings in the domestic, public and industrial sectors and can be located anywhere in the world as they utilise the constant temperature of...

Hybrid Technology © ClimateTechWiki and respective owners

Hybrid technology systems combine two or more technologies with the aim to achieve efficient systems. Possible combinations are: wind-solar photovoltaic (PV) hybrid systems, wind-diesel hybrid...

Hydro Dams for Large-Scale Electricity Supply image large scale hydro

Hydro power plants capture the energy released by water falling through a turbine and converts this into mechanical power, which drives generators to produce electricity. Today’s hydropower...

Methane Capture at Landfills for Electricity and Heat © ClimateTechWiki and respective owners

Under the anaerobic (oxygen free) conditions of landfill sites, organic waste is broken down by micro-organisms, leading to the formation of landfill gas (LFG). LFG is a gaseous mixture which...
