Combined Heat and Power Systems

Combined Heat and Power (CHP) is the simultaneous generation of multiple forms of useful energy (usually mechanical and thermal) in a single, integrated system. In conventional electricity generation systems, about 35% of the energy potential contained in the fuel is converted on average into electricity, whilst the rest is lost as waste heat. CHP systems […]

Biomass Energy Prospects in Southeast Asia

Southeast Asia, with its abundant biomass resources, holds a strategic position in the global biomass energy atlas. There is immense potential of biopower in Southeast Asian countries due to plentiful supply of diverse forms of wastes such as agricultural residues, woody biomass, animal wastes, municipal solid waste, etc. The rapid economic growth and industrialization in […]

Biomass Energy in the Philippines

Like any developing country, the Philippines is facing a formidable challenge of fostering sustainable energy options to support the energy requirements of its economic and social development goals with minimal adverse effects on the environment. In the Philippines, renewable energy sources contribute 43 percent to the country’s primary energy mix, one of the highest in […]

Energy from Woody Biomass

Processing of wood yields by-products and waste streams collectively called residues, which have significant energy potential. A wide range of woody biomass resources are available for transformation into energy in natural forests, rural areas and urban centres. There are many ways to generate electricity from woody biomass using thermo-chemical pathway. These include directly-fired or conventional steam […]

Global Trends in Cogeneration of Bagasse

Cogeneration of Bagasse is one of the most attractive and successful energy projects that have already been demonstrated in many Sugarcane producing countries such as Mauritius, Reunion Island, India and Brazil. Combined heat and power from Sugarcane in the form of power generation offers renewable energy options that promote sustainable development, take advantage of domestic […]

Energy Scenario in Malaysia

Malaysia, with population of about 28 million, is one of the fastest-growing economies in Asia. Although blessed with petroleum resources, this strategically-important Southeast Asian nation is relatively a small producer with reserves of 5.5 billion barrels of oil and 88 trillion cubic feet of natural gas. Malaysia has significant natural gas exploration and development in […]

Biomass from Sugar Industry

Sugarcane is one of the most promising agricultural sources of biomass energy in the world. It is the most appropriate agricultural energy crop in most sugarcane producing countries due to its resistance to cyclonic winds, drought, pests and diseases, and its geographically widespread cultivation. Due to its high energy-to-volume ratio, it is considered one of […]

Output from a Biogas Plant

A biogas plant produces two outputs, biogas and digestate; both can be further processed or utilized to produce secondary outputs. Biogas can be used for producing electricity and heat, as a natural gas substitute and also a transportation fuel. A combined heat and power plant system (CHP) not only generates power but also produces heat […]

Overview of Biomass CHP

Biomass conversion technologies transform a variety of wastes into heat, electricity and biofuels by employing a host of strategies. Conversion routes are generally thermochemical or biochemical, but may also include chemical and physical. Physical methods are frequently employed for size reduction of biomass wastes but may also be used to aggregate and densify small particles […]

What is Trigeneration

Trigeneration or CCHP (combined cooling, heat and power) refers to the simultaneous generation of electricity and useful heating and cooling from the combustion of a biomass fuel or a solar heat collector. Conventional coal or nuclear-powered power stations convert only about 33% of their input heat to electricity. The remaining 67% emerges from the turbines as low-grade waste […]
