Bioenergy is an important renewable energy carrier with uncertainties in future development due to sustainability issues. Its further development requires a robust bioenergy strategy on a national level. To provide these strategy elements, we developed a dedicated approach, which includes a new modeling framework, an impact assessment and stakehold...

Bioenergy policies affect both the environment and biomass availability for food, feed, and fiber on a national and international scale. To support policy makers, knowledge and methods from different scientific disciplines in the form of integrated assessments is necessary. Therefore we developed the MILESTONES framework which models the links betw...

Obgleich diesbezüglich verschiedene und jeweils begründete Vorstellungen seitens unterschiedlicher Akteure bestehen, steht eine abschließende, bundespolitisch legitimierte Definition der zukünftigen Rolle der Bioenergie im gesamten Energiesystem zum heutigen Zeitpunkt noch aus. Dabei bietet die Biomasse – neben dem Einsatz als Nahrungsmittel und al...

Elemente und Meilensteine für die Entwicklung einer tragfähigen und nachhaltigen Bioenergiestrategie Schriftenreihe des Förderprogramms " Energetische Biomassenutzung "

Ziel des hier beschriebenen Vorhabens war es, eine regionalisierte Strategie für einen nachhaltigen Ausbau / eine nachhaltige Stabilisierung der Holzenergienutzung unter Berücksichtigung der Holzkaskadennutzung zu formulieren und zu begründen. Diese Strategie sollte dabei neben dem Leitbild einer nachhaltigen Holzenergienutzung v.a. konkrete Handlu...

From 2010 to 2013, nova-Institute, the Institute for Energy and Environmental Research (IFEU), FiFo Institute for Public Economics at the University of Cologne and Oeko-Institute carried out the research project “Ecological innovation policy – more resource efficiency and climate protection through sustainable material use of biomass” on behalf of...

Die Nachfrage nach Holz steigt, aber seine Produktion kann nur bis zu einem gewissen Grad weiter ausgebaut werden, so dass Prioritäten bezüglich möglicher Holznutzungen gesetzt werden müssen. Hierfür werden die Umweltauswirkungen der energetischen und stofflichen Nutzung von Holz mit und ohne Kaskadennutzung im Rahmen einer umfassenden Ökobilanz un...

This chapter focuses on the background of biodiesel in the United States, the status of the industry in 2009, the changes that have occurred in the industry over the past five years and provides insight into the future of biodiesel in the United States. A combination of factors—high crude oil prices, domestic job creation, climate change, and energ...

Life cycle assessment (LCA) methodology is increasingly used to determine the potential environmental impacts of biofuels and bioenergy. This paper presents the outcomes of screening LCAs of 13 future energy crops for Europe summarizing the results of the EC-funded project 4F CROPS – Future Crops for Food, Feed, Fiber and Fuel. For analysis, these...

Executive Summary Many studies have been conducted world-wide to examine the environmental impact of biofuels for transportation and estimate their cost and quantity potential. These studies have at times shown considerable differences in the findings and conclusions. In order to obtain an overview which identifies the strengths and weaknesses...

Introduction and procedure Comparing with biomass-derived lubricants, in many cases conventional lubricants turn out to have disadvantages for their environmental impact, especially where losses occur during regular operation (e.g. in chainsaws) or where a leakage leads to immediate emissions into the environment as for agricultural machinery. Bio...

The innovative RODSS approach (Reverse Osmosis Deep Sea System — EU-DG XIII innovation project 1998–2001) exploits seawater hydrostatic pressure at a depth of about 450m below sea level. This presentation concerns the deployment and field tests of a small-production-capacity (10m3/d) prototype desalination unit immersed 1 mile offshore the southwes...

The project presented addresses the strategic topic of providing drinking and irrigation water through seawater desalination via a very energy-efficient and cost-competitive submarine technology. In conventional surface based industrial desalination plants applying the reverse osmosis (RO) technology, the freshwater flow behind the membranes is app...
