  • Biomethane enters the gas grid article for energy world

    The Carbon Plan, published in 2011, aims to reduce UK carbon emissions by a quarter from 1990 levels. With the current policies in place, the UK is on target to reduce emissions by over a third by 2020 and with the introduction of new technologies this should increase to an 80% reduction by 2050. However, currently around half the UK’s carbon emissions result from heat related processes and ...

  • Busting Biomethane Myths

    Over the past few years, more and more companies have woken up to the financial and environmental benefits to be gained by making the most of their organic waste streams. In fact, the anaerobic digestion (AD) industry – which converts millions of tonnes of food, sewage and farm waste into renewable energy (biogas) and biofertiliser – has been one of the UK’s biggest success ...

  • Biogas-to-biomethane upgrading plant

    Chesterfield BioGas (CBG) supplied the UK’s first biogas upgrading plant to produce clean biomethane for direct injection into the national gas grid for use by all consumers. The project was successfully completed and gas injected into the national grid at the wastewater treatment site of Thames Water site at Didcot, Oxfordshire in October 2010. This achievement was a benchmark moment for ...

  • Towards a standardization of biomethane potential tests

    Production of biogas from different organic materials is a most interesting source of renewable energy. The biomethane potential (BMP) of these materials has to be determined to get insight in design parameters for anaerobic digesters. Although several norms and guidelines for BMP tests exist, inter-laboratory tests regularly show high variability of BMPs for the same substrate. A workshop was ...

  • Biomethane production at Ontario wastewater treatment plant

    The City of Hamilton is purifying biogas and injecting it into the grid, while continuing to generate power and recover heat from its CHP system. Hamilton, Ontario, has long been a leader in producing biogas from its sewage and storm water wastes. Half a century ago, the city of 520,000 began processing sludge from its sprawling Woodward Avenue Wastewater Treatment Plant through anaerobic ...

  • Case study - Biogas monitoring for upgraded biomethane

    By working with a range of partners worldwide, Geotech is involved in a range of projects at the cutting edge of biogas production and processing.  The recent landmark deal agreed between Marks & Spencer (M&S) and Future Biogas, a major biogas plant operator, is for the purchase of biomethane certificates. The deal sees M&S purchase 35,000 Mega-Watt hours (Mwh) of certificates, ...

  • Biomethanation of solid wastes: analysis of case studies

    Management of the organic fraction of urban solid waste using anaerobic procedures will contribute to the reduction of greenhouse gas emissions, and using biogas, which is a carbon neutral energy, to generate electrical energy will eventually help in reducing the combustion of fossil fuel. Energy recovery in the form of biogas from Municipal Solid Waste (MSW) generated in three different ...

  • Influence of thermal and alkali pretreatment to solubilisation and biomethane production of garden waste

    The objectives of this study were to determine the effect of pretreatment to the garden wastes under thermal and alkali conditions and to evaluate biochemical methane potential. In thermal pretreatment different temperatures and application times were examined and solubilisation improved by heating. Soluble chemical oxygen demand (sCOD) concentration upgraded by increasing temperature with ...

  • Smart Grid needs a Facebook

    We think we know how smart grid technology will change the utility industry. But do we really? Take a look at this documentary made in 1969. It’s a view of how the world perceived the coming Internet (It’s also a pretty amusing look at how sexist our society still was at that point.)  ...

  • Wanted: GOLD for smart grid

    As John McDonald tells it, smart grid needs GOLD. And he’s not talking money. GOLD stands for Graduates of the Last Decade, the technology savvy, risk-taking engineers and technicians who may be among the greatest benefactors of the new smart grid movement. While most recent college graduates face dismal employment prospects, for the GOLD kids, the job ...

  • Smart Grids – The Governmental Approach

    Scott Blake Harris is the General Council for the US Department of Energy, and has recently spoken out at the NGU US summit (hosted by GDS International).   He was nominated in the position by President Barack Obama in March 2009, and was confirmed by the United States Senate in May 2009.  He focused his address on the $4 billion investment into smart grids and renewables across ...

  • The smart money is on smart grids

    In Asia, the utilities industry is growing at an incredible rate. Investments globally in the sector have lead to more available jobs, predicting the return to pre-recession levels of employment by Q1 2010. However, with such substantial growth comes opportunities which have to be managed correctly to sustain long-term development. With the world’s investors looking at Asia to see how such a ...


  • Smarter grids, appliances, and consumers

    More and more utilities are beginning to realize that building large power plants just to handle peak daily and seasonal demand is a very costly way of managing an electricity system. Existing electricity grids are typically a patchwork of local grids that are simultaneously inefficient, wasteful, and dysfunctional in that they often are unable, for example, to move electricity surpluses to areas ...

  • The Grid vs. Rooftop Solar

    The development of solar micro-grids and mini-grids in the remotest parts of Australia seems to be a rational step in the right direction economically. However, network operators all over the world are still in doubt when it comes to the vast population in urban areas adopting similar methods. The question lies with the homeowner choosing to buy the necessary power generating equipment ...

  • Site-specific economic and ecological analysis of enhanced production, upgrade and feed-in of biomethane from organic wastes

    The present study analyses the cost structure and ecological performance of biomethane production and feed-in from organic wastes and manure in a site-specific approach for Upper Austria. The theoretically available quantities of biowaste and manure can feed representative biogas plant capacities resulting in relatively high biomethane full costs in the natural gas grid of at least 9.0 ...

  • Recovering biomethane and nutrients from anaerobic digestion of water hyacinth (Eichhornia crassipes) and its co-digestion with fruit and vegetable waste

    The potential to recover bioenergy from anaerobic digestion of water hyacinth (WH) and from its co-digestion with fruit and vegetable waste (FVW) was investigated. Initially, biogas and methane production were studied using the biochemical methane potential (BMP) test at 2 g volatile solids (VS) L−1 of substrate concentration, both in the digestion of WH alone and in its co-digestion with FVW ...

  • The mathematical modelling of biomethane production and the growth of methanogenic bacteria in batch reactor systems fed with organic municipal solid waste

    A mathematical model was developed and validated for an anaerobic digestion system of the Organic Fraction of Municipal Solid Wastes (OFMSWs) by using a laboratory-scale system of two Packed Bed Reactors (PBRs). The equations were obtained by the mass balances of methanogenic bacteria of affluent and effluent lixiviated, as well as the interior in each reactor. The methane rate was obtained by ...

  • Smart Grid: The game

    In his best seller “Outliers,” Malcolm Gladwell shows that it is not equipment failure or storms that typically cause planes to crash, but wrong decision-making. Much the same can be said for the power grid crash that took down a large swath of the Northeast in August 2003. The emerging smart grid is supposed to make our power system more reliable. The bad news is that it also will add complexity ...
