Energy content of biofuel Energy content of biofuel The Energy content of biofuel is a description of the potential energy contained in a given biofuel, measured per unit mass of that fuel, as specific energy, or per unit of volume of the fuel, as energy density. A biofuel is a fuel, produced from living organisms. Biofuels include bioethanol, an alcohol made by fermentation—often used as a gasoline additive, and biodiesel, which is usually used as a diesel additive. Specific energy is energy per unit mass, which is used to describe the energy content of a fuel, expressed in SI units as joule per kilogram
Home Energy Resources Unit Home Energy Resources Unit The Home Energy Resources Unit or Home Energy Recovery Unit (HERU) is a prototype kitchen appliance which is claimed to use household waste to generate energy. Household waste, both organic and inorganic, is placed into a main chamber. Plastic and cardboard packaging as well as food waste can be inserted as fuel, and the waste does not need to be sorted or separated. It then goes through an eight-hour cycle. The chamber containing the waste is heated to 100° celsius to evaporate water and remove oxygen. The temperature is then increased and pyrolysis takes place. Oxygen
