Renewable Energy

The signing of the Kyoto Protocol in 1997, claims to be the birth of the energy transition, which is already the largest insurmountable technical challenge facing humanity in advancing the 3rd millennium. While the finiteness of fossil fuels is becoming more apparent it is up to specialized and highly trained engineers in the next few decades to pave the way towards a sustainable energy supply of the future.

Since 2002 the research cluster Renewable Energies, together with his students exactly has been targeting this task. The development of a Biobased Economy is the central focus of the research activity. Priority areas include the supply of energy from biomass, increasing energy efficiency, optimized heating / cooling networks, conversion / processing of biomass to useful materials for the pharmaceutical and chemical industries.

Valorization of Biomass

To make a complex structure of biomass for energy and material use as efficiently as possible and accessible in consistent quality, the optimized storage to prevent loss of substance and basis transformations of the predominantly carbohydrate and lignin-based materials is researched in this area together with its drying, pelletizing and exploitation in the direction towards biochar.

 

Biomass to Power and Heat

The development of systems and equipment for the generation of electricity and heat from woody biomass is the goal of this research area. The focus is not only a decentralized, sustainable energy supply objective in mind, but also to maximize the efficiency and especially the flexibility of the raw material used.

 

Engine & Emissions

Given the fact that internal combustion engines represent the backbone of current mobility solutions and play a significant role in the area of energy supply, the research division Engines & Emissions particularly addresses issues related to alternative fuels, internal combustion and technologies for the reduction of emissions.

 

Energy Distribution and Storage

Decentralized heating and cooling often becomes an economic and emissions related challenge. In opposite centralized systems can be operated with highest efficiency and minimum pollutant and CO2 emissions, but they need appropriate distribution and storage. Object of this research area is therefore the investigation and development of new distribution networks and storage systems at different temperature levels for different producer and consumer technologies.

PLG_RESEARCH_BESCHREIBUNG:
The use of gas engines represents the commercially most efficient way of producing electricity and heat from combustible gases. Gas engines can use gaseous fuels of highly varying composition; furthermore they show high operating safety and reliability. The ability of efficiently converting biogas and synthetic gases and the high potential of a decentralized application generate economic growth within the bio energy sector. For high electrical and thermal efficiency a rapid combustion inside the gas engine is of key significance. Hence, optimizing motor parts and fuel flow speed to increase charge movement and combustion speed will be the major goal of this project. The project HiGas will reflect on the potential of optimizing the charge movement speed and turbulence of the combustion on a new state of the art gas engine provided by 2G Energy GmbH. There will be cylinder head and spark plug development as well as optimizing of operating strategies. As a result a significant increase in thermal efficiency with a coincident reduction of emissions is expected.

PLG_RESEARCH_BESCHREIBUNG:
In the thermochemical conversion of solid biogenic raw materials (gasification) the utilization of the gas in efficient gas engines, and thus the conversion into electricity and heat plays a crucial role. Conventional gas engines are for the use of wood gas only conditionally suitable (low efficiency) and there are to make appropriate modifications. Our project partner PGES has developed such a modification set whose performance and suitability in detail now by conversion of an existing gas engine and integration into the gasification test facility PowerBox in Schwaz will be examined. The results from this project can make a valuable contribution to the future commercialization of biomass CHP plants based on gasification technology.

PLG_RESEARCH_BESCHREIBUNG:
The use of alternative, biogenic resources, briefly called ABR, as energy is a key factor in the implementation of a global energy revolution. The at the MCI 2007 developed thermochemical conversion process by stepped floating bed gasification provides optimal, procedural prerequisites to turn such raw materials efficiently into electricity and heat. While the utilisation of low quality wood chips could be conducted to commercial maturity in the first phase of the project, the target now is to make the technology fit to utilise ABR.

PLG_RESEARCH_BESCHREIBUNG:
Biomass - for example sewage sludge, algae or foliage - has attracted much research attention as potential renewable resource. While there are multiple different pretreatments availible, the hydrothermal carbonisation (HTC) is sticking out as a environmentally compatible and future-oriented method. HTC is a technique where biomass is converted to coal-like substances using elevated temperatures and pressures and water. This approach yields three distinct advantages:
- The needed temperatures are often lower than for alternate methods.
- There is no need to dry the biomass beforehand, removing a very energy consuming step.
- Waste gases are partially solved in the process water und are thus captured, possibly making a costly posttreatment obsolete. The goal of this study is a better understanding of the reaction kinetics und the chemistry involved in this fascinating reaction - any broadening of the basic knowledge might help to ensure practical implementation of the process in the future.

PLG_RESEARCH_BESCHREIBUNG:
The biochar from the floatind fixed-bed gasification process is not, like other bioenergy plants, usually a residue or waste. Because of the characteristics and the degree of purity, the biochar should be classified as a multifarious resource. The indicated peculiarities of biochar from CraftWERK-plants represent the base for this project. The goal of the project is the representation of recovery and application possibilities of biochar from CraftWERK-plants and compare among each other. It aims to identify the recovery possibilities witch are in short-term, regional, profitable and without elaborate preparation of biochar are possible. In addition to the short-term recovery possibilities there should be identified which provides, in the medium-term for large quantities, good potential markets. From that objective for the project, the following three project goals can be defined:
- Quality comparison of different biochars
- Developing rapid analysis method for PAHs in biochars
- Requirement / list of criteria: applications for biochar

PLG_RESEARCH_BESCHREIBUNG:
For testing and first run of motor cycle engines after manufacturing the engines are filled with motor oil that later is recovered after testing is done. Since there is metal grit and other left over material from the manufacturing process inside the engine the oil is also used to flush the engine. Hence, after the test run the oil is no longer suitable to run the engine. From ecological and economical aspects the recovered oil is collected and regenerated for reuse. The solid materials can be mechanically separated (filtration) but water containing refrigerants coming from the manufacturing process reduce the lubricants performance as well. At the moment the refrigerant is separated by a vacuum vaporizer. Depending on additives some motor oils are able to tolerate critical amounts of water before decomposition or phase separation. The amount of water that can bind with the oil depends on the age of the lubricant. Therefore it is hard to give reliable predictions on saturation points, water content and overall quality of the reused oil. Within this research project a correlation between the water content and the number of tested engines will be evaluated. Time depending measurements of the water content and records of KTM about type and number of test runs should give the information needed. Furthermore an experimental measurement of the saturation points of selected oil samples will be compared to results from a sensor for online measurements. Measurement and analyses of the solid waste content of the recovered motor oil is another minor project goal.

PLG_RESEARCH_BESCHREIBUNG:
The follow-up project "Biomass conditioning 2" aims to describe the wood degradation and self-ignition process inside woodchip piles, based on different laboratory analyses. Additionally, a survey is being conducted in Western Austria to define parameters and circumstances where self-ignition of stored woodchip piles has occurred in district heating plants. After finishing these preparatory experiments a model of a woodchip pile and its behavior will be prepared in a follow-up project in order to enable a forecast of material losses and the risk of self-ignition.
