  • CHP efficiency for biogas

    Combined heat and power plant efficiency is a function of the conversion efficiency of the energy in the fuel gas to useful energy in the form of electricity and heat. A combined heat and power (CHP) plant is typically a reciprocating gas engine that uses the energy in the gas to drive a crank shaft. The crank shaft turns an alternator to ...

  • Energy from biogas

    From an ecological and economical perspective, biogas is an important source of energy. The fossil resources are limited, and they impose a high burden on the environment. A resourceconserving alternative made from biomass poses a different scenario. The raw material is renewable, and conversion only releases as much CO2 as was previously contained by the source material. With the technological ...

  • Using biogas for combined heat and power

    An integral part of the majority of anaerobic digestion facilities across the world is the CHP combined heat and power (CHP) engine. For the first time builder of a biogas plant, it is often neglected as the focus is on reducing the capital costs ...

  • Effect of the solid content on biogas production from Jatropha curcas seed cake

    Anaerobic conversion of Jatropha curcas seed cake was studied in a five–litre working volume batch reactor at 30°C. Over a 60–day operating period, a slurry of seed cake in water at a 1 : 20 seed cake–to–water ratio showed the highest methane yield of 296 litre methane/kg Chemical Oxygen Demand (COD) degraded (or 156 litre/kg of Jatropha curcas seed cake added) and achieved 52% COD removal. The ...

  • Assessing Feasibility of Direct Drive Technology for Energy Recovery from Digester Biogas

    ABSTRACTThe Regional Municipality of Waterloo completed a study, with support from Environment Canada, to evaluate the feasibility of using direct drive technology to recover energy from digester biogas. The study identified that a 150 HP engine, operating at 54 % load, could be supported by the estimated gas production of 1560 m3/d with 63 % methane by volume. ...

  • From biogas to natural gas - A new renewable fuel supply line

    Continents and countries that depend on fossil fuels, such as Europe, and within Europe, northern Europe, are increasingly looking with interest at renewable energies and are committed to developing such energies as a source for future development. Biogas from different sources is a valuable material for the production of energy, chemical products and bio-fuels. Because it is a renewable energy, ...

  • Research and development on biomass energy in China

    Like developed countries, China is facing two serious constraints energy shortage and environmental pollution, which hinder the development of the national economy and improvements in living conditions. On the other hand, China has a huge amount of biomass resource. It is estimated that the total amount of biomass resource is up to 5.2x108 tons of oil equivalent (TOE) in which crop residue ...

  • Thermochemical pretreatment of lignocellulose residues: assessment of the effect on operational conditions and their interactions on the characteristics of leachable fraction

    Annually, large amounts of agricultural residues are produced in Chile, which can be turned into a good opportunity to diversify the energy matrix. These residues have a slow hydrolysis stage during anaerobic digestion; therefore, the application of a pretreatment seems to be an alternative to improve the process. This work focused on applying a thermochemical pretreatment with NaOH on two ...

  • What is energy recovery?

    Processes like incineration and anaerobic digestion not only provide sources of energy, but they also reduce waste volume The term “energy recovery” often is applied only to a narrow number of methods for converting wastes into energy, when in fact it applies to a broad range of technologies used to create heat, electricity, or fuel. Energy recovery gives ...

  • Biomass and Integration in Future Energy Systems and the Bioeconomy

    Biomass was the primary source of materials and energy until the industrial revolution set off a series of major changes around two hundred years ago. In the industrialized world fossil fuels became the primary source for energy in the forms of electricity and heat and provided almost all fuels for transport. However, biomass continued to maintain an important role in the economies in both ...

  • Renewable energy marketplace

    ALLU Group markets two types of equipment for use in biomass energy operations. The ALLU Screener Crusher bucket attaches to a front-end loader. The bucket is designed to aerate, crush, screen and mix at one time. The Screener Crusher has a rigid steel frame, onto which horizontally rotating screening and crushing drums are mounted. All the drums rotate in the same direction. There are several ...

  • For a Green Future: an Overview of Biomass Energy in China

    Biomass energy Biomass refers to biological materials or organic materials which is renewable and sustainable and could be used as a fuel source. The energy derived from the biomass materials  is called biomass energy. Biomass energy as one type of renewable energy has be developed with priorities in China. Current situation of Biomass resource in China ...


  • How did palm oil become such a problem — and what can we do about it?

    Production of this ubiquitous ingredient is devastating for the environment. Solutions are complex, but they are out there. Last August, from the window of a jet high over Sumatra, I counted nearly a dozen plumes of smoke rising from the vast jungles and plantations below. Some more than a half-mile wide, they looked like pillars holding up the sky. That week the ...
