  • Why did GHG emissions decrease in the EU in 2012?

    Total GHG emissions (excluding LULUCF) in the EU decreased again in 2012, reaching its lowest level since 1990. This continued the trend of emission reductions, which started in 2004. In line with EEA predictions last year2 GHG emissions between 2011 and 2012 decreased by 1.3 % in the EU28 and by 0.8 % in the EU-15. Figure 1 shows total greenhouse gas emissions in the period 1990–2012, both ...

  • Dreyer & Bosse deliver renewable energy CHP project to Sofia in Bulgaria

    The Sofia council decided to invest in renewable energy to make use of the many tons of biowaste (vegetative material),  20,000 tons per annum, from the waste removal collections that take place daily in Sofia and surrounding area. To make this possible it was decided to go for wet fermentation where the substrate or raw material ferments and the biogas is collected. After three weeks the ...

  • Specialty Gas Report - Maximizing the Potential of Gasification Facilities – Simple Solutions, Huge Benefits

    Here and now gasification plants have the functionality to make the hydrogen economy a real possibility. Greatly reducing the cost of hydrogen production by using renewable resources and advanced, reliable processing techniques enables a gasification plant to produce valuable hydrogen product from waste materials. While the technology is available to enable this functionality, however, most ...

  • Co-Fire Naturally

    PRM Energy System’s Naturally Gas Cofiring Machine Your PRME Naturally produced biogas will come from biomass – not fossil fuels. Technically speaking, you will be “co-firing” gas produced by the thermal gasification of biomass. PRME’s Naturally Gas Co-firing process design is not experimental or “under development”, but has been commercially firing ...

  • The hydrolysis and biogas production of complex cellulosic substrates using three anaerobic biomass sources

    In this study, the ability of various sludges to digest a diverse range of cellulose and cellulose-derived substrates was assessed at different temperatures to elucidate the factors affecting hydrolysis. For this purpose, the biogas production was monitored and the specific biogas activity (SBA) of the sludges was employed to compare the performance of three anaerobic sludges on the degradation ...

  • Biogas as an option for industrial applications

    Biogas is typically burned to produce electricity or used as vehicle fuel. This case study analyses possibilities to utilise biogas directly in industrial applications to replace current fossil raw materials. True industrial cases are analysed by considering economic impacts of using either landfill gas or gas produced from biomass. Utilisation of biogas is economically viable and technically ...

  • Keeping the eye on the ball

    Reinier Zwitserloot may not be among the world’s most famous corporate executives, he is one of the most influential. In his eight years as head of German gas and oil producer Wintershall, a subsidiary of BASF, the Dutchman, who is retiring on the first of October, managed to build up an impressive network of political contacts in Germany and Russia. And he grew the business. ‘If you really want ...

  • Effect of different solid concentration on biogas yield and composition during anaerobic fermentation process

    The anaerobic fermentation experiments were carried out on a self-manufactured bench scale anaerobic digester with pig dung as feed material. Under mesophilic digestion condition, effects of different solid concentration of feed on characteristics of biogas production were investigated. Results showed that daily average biogas production rate and total biogas yield were increased with the ...

  • Spatial diffusion of biogas technology in Switzerland: a GIS-based multi-agent simulation approach

    In this paper, we study the viability and spatial diffusion of agricultural biogas technology in Switzerland by means of a multi-agent simulation model. The simulation process displays the estimated dissemination of biogas technology in the different regions of Switzerland over the period from 2006 to 2025, taking the varying circumstances for biogas use in each region explicitly into account. ...

  • Ukraine`s new 2009 green tariff

    Ukraine’s government has been quite proactive during the first half of 2009 with regard to the renewable energy and carbon sectors. In April, the President approved a 'revised' Green Tariff rate calculation methodology, resulting in even higher prices than before for alternative energy producers.Also the government has been working to complete Ukraine’s Green Investment Scheme through the ...

  • Solution concepts for the production of biogas

    With its products that go to form part of biogas plants, it is not only a significant pioneering role that Hofstetter Umwelttechnik AG in Switzerland deserves. The company in Berne also adopts a leading position on the worldwide market for utilizing biogas. Hofstetter products – the socalled flares and compressor stations – are designed both for fermentation plants for biomass and for plants for ...
