Opis:: Transport is responsible for around a quarter of EU greenhouse gas emissions making it the second biggest greenhouse gas emitting sector after energy. Biogas is one of the cleanest and most versatile renewable fuels available today, answering on challenges of EU sustainable development strategies. Upgraded biogas–biomethane–has the same advantages as natural gas, but additionally is a sustainable fuel that can be manufactured from local waste streams thereby also solving local waste problems. During the last years, the production and use of biomethane has significantly increased in many European countries. Sweden is world leading both in terms of automotive use of biomethane and its non-grid based transportation.

Opis:: This paper discusses generally the possibility of reduction carbon dioxide and nitrogen oxides emissions from internal combustion engines of vehicles by using biomethane. The road transport in Europe almost fully depends on fossil fuels. Diversification of the road transport fuels will be a key attribute for road transport in the coming years. Purified biogas is one of alternative renewable fuels. Actually, in Poland biogas is used for generating electricity and heat. In some countries (for example in Sweden), upgraded biogas to natural gas quality (biomethane) is used as a vehicle fuel too. In this paper estimated biogas production potential in Baltic See Region countries: Poland and Sweden. It was one of the purposes of European Project Baltic Biogas Bus, and it is taken into account in European Project More Baltic Biogas Bus realized presently. Comparative studies of exhaust emissions of carbon dioxide and nitrogen oxides from city buses powered by diesel and CNG engine were carried out. The study was conducted under real traffic conditions in southern Polish city Rzeszow. Due to the lack in-service city buses with emission level Euro V in Rzeszow, comparative studies of this type of city buses powered by diesel and CNG engine was conducted in SORT I test. Determined mean values of road emissions of carbon dioxide and nitrogen oxides in g/km for the city buses operated in Rzeszow. Estimated value of the total road emissions in the case that would be replaced half the fleet of city buses (40 CNG buses and about 35% of the diesel engine powered buses, meet Euro III emission standard) by the CNG-powered (biomethane) city buses, complying with Euro V (EEV) emission standard.

Opis:: In the recent years, the European Community has been implementing a plan to increase the share of renewable fuels used for energy production and powering vehicles. It aims to partially reduce the dependence on crude oil imports and reduce CO2 emission. Particularly interesting are the achievements of Sweden against this background, for which the European Commission has set the highest value of the indicator, and to implement which Sweden adopted unconventional solutions across Europe. One of them is the plan to eliminate by the 2030 fossil fuels from the urban transport, and one of the fuels that is to replace today still widely used diesel oil, would be biomethane. The article describes the reasons and circumstances which made Sweden use biomethane to power buses used in urban transport on a very large scale, in comparison with other European countries. The article shows the characteristics of this fuel, the method of its production and application prospects.

Opis:: Depletion of fossil energy sources, and thus the prices increase of conventional fuels such as gasoline or diesel fuel, the energy security and dependence on imported fuels, as well as the deteriorating environment and global warming mean that there are more and more new technologies using renewable energy sources nowadays. In the medium- and long-term perspective a significant changes are needed regarding means of transport in ensuring "sustainable mobility", while the horizon of short-term solution is the implementation of biofuels, including biogas refined to form of biomethane, and renewable alternative fuels. Biomethane is produced from waste organic matter. Directive 2009/28/EC indicates the benefits of using waste for the production of transport fuels, to decarbonisation of the energy sector and requires Member States of UE to use renewable fuels. The paper presents possibilities for the biomethane production, as well as conditions to use it as fuel to power city buses. The level of current use of gaseous fuels in the national urban transport was specified, and also conducted an evaluation of benefits, especially ecological, to use these fuels for these applications.

Opis:: Biogas production has a big potential to provide clean energy. To evaluate the future production and maturity of biogas technology the generalized Weng model was proved to be effective, due to it has the minimum error. The simple algorithms to determine its parameters have been proposed. The simulation results for China, USA, and EU have been presented. The quantity and quality analysis for biogas feedstock has been carried out. Energy Return on Energy Invested (EROEI) indicator for different biofuels was considered. According to analysis done biogas from maize residue and chicken manure has high EROEI. Shannon Index was suggested to evaluate the diversity of feedstock supply. Biomass energy cost indicator was grounded to be used for feedstock energy and cost assessment. Biogas utilization pathways have been shown. Biogas boilers and CHP have the highest thermal efficiency, but biogas (biomethane) has the highest potential to earn as a petrol substitute. Utilization of biogas upgrading by-product (carbon dioxide) enhances profitability of biogas projects. Methods to assess the optimal pathways have been described.

Opis:: The subject of this publication is to determine the impact of biogas plants on the environment, with particular emphasis on greenhouse gasses emissions associated with the production and management of biogas as the main plant product. The environmental impact of the agricultural sector as well as the state of development of the biogas market in European Union are presented as background for consideration of greenhouse gas emissions. One of the economy sectors responsible for GHG emissions is agriculture. One of the solutions of GHG reduction in agriculture is slurry management using biogas technology. It should be emphasized, that biogas not always has favorable emission parameters. The final emission throughout the whole life cycle of this energy carrier depends on many factors. The structure of GHG emissions largely depends on what type of raw material it used for biogas production and in what kind of tanks the digestate sludge is stored. If waste raw materials are used for biogas production, then GHG emission associated with their acquisition is assumed to be zero. On the other hand, if dedicated energy crops are used for biogas production, the emission connected with cultivation of these plants are added to the total GHG emissions. They are directly related to the use of fertilizers and plant protection products, field emissions of nitrous oxide and fuel combustion during the operation of agricultural machinery. Influence on the GHG emission has also the kind id digestate storage tank. If these are closed tanks, there is no emissions to the atmosphere. If tank is open, then methane is emitted directly to the air and is included in the total GHG balance.

Opis:: The development of societies building modern economies and production was and is associated with the continuous growth of energy consumption. Nowadays the world was forced to take a different look at the problem of energy consumption and fossil fuels. Because of cost of mining and production, unstable political situation in resource-rich countries and ecological perspective, many scientists seeks renewable energy sources, in quantity sufficient to meet the demand. Because of development of technologies obtaining many types of renewable energy sources that can be adapted to the needs of energy and the environment in which it will be received. Because of rich resources of ingredients that make production possible biogas, it is the most appropriate renewable fuel for agricultural infrastructure. The paper comprehensively describes factors influencing the development of renewable energy to their nature and technology in the application of renewable fuel gas with particular reference to methane gas and biomethane. There is general agreement on the Reed for sustainable biofuel industry, there is little understanding on how to avoid social and environmental degradation with global biofuel production. Results showed a variety of government policies, the most significant of which concerns agricultural production. In analyses the impact of government's policies on promotion of affordable, alternative energy sources capable of maintaining current energy consumption standards.

Opis:: The objective of the present work was to determine the effect of pretreatment by extrusion on the biogas and biomethane yield of lignocellulosic substrates such as maize silage and maize straw silage. The biogas yields of the substrates before and after treatment were compared. Moreover, energy efficiency of pretreatment by extrusion was analyzed in order to assess the applicability of the process in an agricultural biogas plant. Extrusion tests were carried out in a short single-screw extruder KZM-2 in which the length-to-diameter ratio of the screw was 6:1 and rotational speed was 200 rpm. The biogas yield tests of the plant substrates after extrusion were carried out in a laboratory scale, using 15 biofermenters operated in a periodic manner, at a constant temperature of 39°C (mesophilic digestion) and controlled pH conditions. The gas-emission analysis was performed using a certified gas analyzer from Geotech GA5000. Pretreatment by extrusion was observed to improve the quantity of methane generated: in terms of fresh matter for maize silage subjected to extrusion, the methane yield was 16.48% higher than that of the non-extruded silage. On the other hand, maize straw silage after extrusion gave 35.30% more methane than did the same, non-extruded, material. Differences in yields relative to dry organic matter are also described in this paper. Taking into account the amount of energy that is spent on pretreatment and the generated amount of methane, the energy balance for the process gives an idea of the economics of the operation. For maize silage, energy efficiency was lower by 13.21% (-553.2 kWh/Mg), in contrast to maize straw silage, where the increase in energy was 33.49% (678.4 kWh/Mg). The obtained results indicate that more studies on the pretreatment and digestion of maize silage are required in order to improve the efficiency of its use for making biogas. To fully utilize its potential, it is necessary to know thoroughly the effect of the extrusion process and of biogas production on energy efficiency at different conditions.
