Biomass Biogas

• Biogas is a clean, un-polluting, smoke and soot free fuel. • It contains 55 to 70 percent methane which is inflammable. • It helps in simultaneously obtaining both cooking fuel and enriched manure from cattle dung. • It caters the needs of community as whole and institutions. The Biogas generated from these plants is utilized for cooking and operation of duel fuel engines for floor milling, chaff cutting, water pumping & generating electricity

Biomass Cogeneration • Many industries such as sugar, palm oil, rice and wood have been utilising biomass as a fuel to cover some or all of their energy requirements. Biomass is one ofthe most important sources of renewable energy in the region. • Most countries are large producers of wood and agricultural products which, when processed in industries, can produce large amounts of residues, varying between 20 to 70 % of the raw material input.

• To make better use of a biomass energy source, cogeneration is an area of potential. Cogeneration in term of biomass for heating as well as electrical generation. • By producing both heat and electricity can dramatically increase the efficiency of the amount of energy captured from the biomass.

• There are two main ways in which both heat and electricity can be generated for cogeneration. • One of them being modern closed loop steam engines. These units are far more efficient than previous steam systems, and recycle the hot water, so only a small amount of energy is required to turn that hot water back into steam to move the pistons, which in tern mover the generator to produce electricity.

Biomass gasification Gasification is the other alternative to the closed loop steam engines. Biomass gasifier system is basically a reactor in which wood chips/cotton stalks and other woody biomass is burnt in a controlled quantity of air to produce combustible gas generally known as producer gas.

New Innovation!!

• The biomethane project that turns human waste into green gas went live on the 5 th of this Month. This project is now converting the treated sewage of 14 million Thames Water customers into clean, green gas and is pumping that gas into people's homes.

Advantages Industry and other investors • energy solutions for various biomass streams Energy sector • decentralization • avoid electricity transmission & • distribution losses • greater use of renewable energy • improve local energy security • reduce fuel import needs

Environment • reduce greenhouse gas emissions and other pollutants • reduce impacts from waste disposal Agriculture and forestry • enable diversification • create rural revenue streams • create / maintain jobs

Weakness! • • Multiple benefits not economically rewarded Advanced technologies unproven Potential fuel supply logistical problems Poor data on economic available biomass potential • High capital costs, no economies of scale • Many potential applications have low heat demand
