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...

Coal mine/bed methane recovery © ClimateTechWiki and respective owners

Methane is the primary constituent of natural gas and is stored within coal as a result of the coalification process whereby plant material is converted to coal. Due to coal mining activities (and...

Combined Heat and Power (CHP): large-scale © Climate Tech Wiki - acc and respective owners

Co-generation is the combined production of useful thermal energy and electricity (Combined Heat and Power, CHP) from the same primary fuel. CHP can take on many forms and encompass a range of...

Combined Heat and power (CHP): small-scale small cogeneration system

Co-generation is the combined production of useful thermal energy and electricity (Combined Heat and Power, CHP) from the same primary fuel. CHP can take on many forms and encompasses a range of...

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...

Fuel cells for stationary applications Molten Carbonate Fuel Cell in a T-Mobile data center in Munich

Fuel cells make it possible to efficiently convert the energy stored in several kinds of gases, among which hydrogen and methane, into electricity. Although the concept, according to which fuel...

Gasification of Municipal Solid Waste for Large-Scale Electricity/Heat © ClimateTechWiki and respective owners

Thermal gasification of municipal solid waste (MSW) is a chemical process that generates a gaseous, fuel-rich product. This product can then be combusted in a boiler, producing steam for power...

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...
