Gröna transportkorridorer

The economic development and competitiveness in Europe is heavily dependent on an efficient transport system. Movement of goods and people is essential for a competitive industry and successful trade. As a result of an intensified transport business, consumption of fossil Fuels has increased dramatically. As a consequence, there are increased emissions of dangerous greenhouse gases. Transports are often mentioned as an area with high impact on the environment.

Olika uppvärmningssystem : en fallstudie i mellansverige

The purpose with this project is to compare different Fuels when investing in a central combustion station at a case study farm. I have chosen to write about biofuel from an economical perspective. This because the heating costs are steadily increasing. Also because the farm in this case study has several different heating systems, which are neither profitable nor easy to work with. I have made calculations regarding usage of splinter, wood and grain for the heating system.

Rötning av matavfall ? en studie av metanutbytet hos matavfall förbehandlat med skruvkrossteknik samt vid samrötning med bioslam från pappersbruk

Today's society is facing major challenges. In order to reduce the climate impact fossil Fuels should be replaced with Fuels that do not contribute to the greenhouse effect. The growing population generates organic waste originating from industry and households so called organic fraction of municipal solid waste (OFMSW). Through anaerobic digestion, waste can be utilized to produce energy-rich methane gas. In this way, waste can be a resource instead of a burden on society.

Vätedriven förbränningsmotor : Klarläggande av framtida hållbarhet

Today when new and harder demands on CO2 emissions are developed, vehicle manufacturers must work to develop new engine solutions to new kinds of Fuels to replace fossil Fuels. A fuel that could be applied is hydrogen. When hydrogen is combusted only water vapor occurs. Hydrogen is known to be explosive and flammable. These properties are both good and bad for combustion.

Skogsbränslets fraktionsfördelning

This study has analyzed particel size distribution and needle content in chipped logging residuals (branches and tops) delivered to the district heating plant Ryaverket in city of Borås, Sweden. Two fuel assortments has been analyzed: Chipped logging residuals from pure softwood and from mixed fuel (connifers and broadleaves). The samples has been sieved at Linneaus University laboratory.The study of particle sizes indicates that only 53,2 % of delivered fuel is within the Fuels specification (7? 45 mm). The needle content is in this study 12,4 % (dry mass) which is higher than expected..

Analyzing the future of technology and society. Scania and the case of the Russian fuel market.

Issue of study: The development of technology and society is closely linked. Mutual dependency and complex interrelationships make straightforward analysis of issues regarding the future of technology and society hard to perform. Therefore, the study addresses the question of how organizations should describe and analyze the interactions of technology and society in order to gain a better understanding of what the future may bring. Purpose: ? To develop a method for analysis of the future course of issues regarding technology and society in interaction.? To apply and test the developed method through a case study, where it is used to analyze the future of the Russian fuel market.

Hållbar energi : - Ett initiativ till utveckling av bränsleceller i Sverige

In the world we live in today the environmental issues has become increasingly important, and we have begun to realize that we can not continue to use fossil Fuels at the rate we do. When it comes to generating electricity we are constantly trying to come up with cleaner and more efficient solutions. The fuel celltechnology is one such alternative and has been around for over 100 years. Yet, it is not until now that the world has started to notice this great technology. The fuel cell has been developed in several areas and can today be used for handheld electronics, vehicles and small settlements.

Stockholms Energiframtid : En backcastingstudie för ett fossilbränslefritt Stockholms län 2050

This study concerns the energy future of the county of Stockholm up until 2050 and describes how the energy consumption can be compared to today with the use of scenario methodology. Within energy future studies the backcasting approach is well known and has been put to use in this study. Due to the characteristics of backcasting the study is self-fulfilling, i.e. the future energy scenarios presented in this study satisfy the targets set up in this study. In the light of what may be the largest challenge of our time ? the climate change - the aim of this study is to describe how the energy consumption in a fossil fuel free Stockholm county in the year of 2050 may be.

Ödesstund för Europa : Om de geopolitiska konsekvenserna av Europas beroende av rysk energi

This is a tale about energy and power. It describes the geographer Halford Mackinder?s geopolitical theories and compares them with current views outlined by Zbigniew Brzezinski and Michael T Klare, among others. With a critical approach it also provides a historical account of a Europe that stands in front of an energy struggle so severe that the current world order seems destined to fall. Oil and natural gas, has since the beginning of the 20th century, been used as a geopolitical tool in order to create dependence, control and even sometimes overthrow empires.

Optisk sortering av matavfall : en jämförelse med en minskning av svinnet

The purpose of this study is to compare the energy related and environmental consequences of implementing optical sorting as a means of waste collection with those of reducing food waste. In addition to studying the possibility of implementing optical sorting in downtown Stockholm, the yielded amounts of energy from waste collection and reduced wastage will be calculated. This is done by way of literature reviews and interviews. The amount of energy that can be generated through optical sorting and biogas production via anaerobic digestion in downtown Stockholm is 29-44 TJ/year, compared to 118 TJ/year saved by completely eliminating food waste. The generated biogas can replace fossil Fuels, but the required food waste contributes to increased greenhouse gas emissions as well as reduced bio diversity and eutrophication during the wasted food?s lifecycle.

MIKROVÄRMEKRAFTVERK för hemmabruk

My questions at issue for this report has it´s beginning in the growing problems of thenegative effects of burning fossile Fuels and the rapidly growing energyprices.1. Is it possible to design a micro scale powerplant?2.

Grön olja? - En fallstudie av ett oljebolags miljöprofilering

While the call for regulations against greenhouse gas emissions are louder then ever before, demand for oil is also at an all time high. Oil companies face the dilemma of making sound business without being perceived as environmental villains. In this essay I will examine how BP, one of the largest companies in the world, broke rank with the industry and devoted itself to being an environmental friendly oil company. The actions and motives of this change will be evaluated through up-to-date theories about company motivation to environmental adaptation. We see that BP:s transformation can be well explained through Simone Pulvers theory about the socially embedded company.

SEO-vänligt CMS med ASP.NET MVC

Fossil Fuels are affecting our climate negatively and there is a limited amount of them in the world, which leads to the importance of finding alternative Fuels. One alternative is biogas, which is produced though a digestion process of different organic materials in a biogasreactor. Organic substrate that comes from farms has the biggest potential to increase the production of biogas in Sweden. Primarily crops from farms, but also waste products like manure are of great importance.Today there is a calculated theoretical potential for biogasproduction of 14TWh per year, which is around ten times larger than Sweden?s production today.
