We have set out to develop a drone, based on the existing Delftacopter, capable of soil monitoring via LiDAR remote sensing. The battery was to be replaced by a fuel cell system in order to extend the range threefold to 180km. Unfortunately, the ultimate design is likely unfeasible. Agriculture requires healthy soil and monitoring soil health is...

The integration of variable renewable energy sources (RESs) in the electrical power grid leads to larger and faster variations in the power demanded from controllable power sources. This is a problem, because flexibility of (base load) power plants is limited. Solid oxide reversible cells(SORCs) can be used as load-shifting devices to reduce...

Energy storage systems are an emerging field of interest for the future of electrical grids. With the rapid growth of renewable but intermittent sources of electricity, energy storage systems can help smooth the variations, making the grid more stable and reducing the need for maintaining an overcapacity of power production infrastructure. Among...

In a effort to curb climate change, more and more countries are adding solar and wind farms to their electrical grid. These solar and wind farms produce electrical energy based on environmental conditions, for example solar irradiation intensity or wind speed. As such these farms create fluctuations in the electrical grid and create a mismatch...

As all industries move towards sustainable fuels to reduce emissions, aircraft industry is still at its nascent stages. The adoption of clean energy sources has been slow particularly due to low energy density of commercially available batteries, and high volumetric density of hydrogen as a fuel. Electric aircrafts have been demonstrated but...

A lot of scientific research has been focusing on energy storage systems recently and there are numerous reasons for that. First of all, they can nullify the intermittent nature of renewable energy technologies, by storing excess energy in times of heightened solar irradiance and wind levels and utilizing it when electricity demand is surging. A...

The intermittent nature of renewable energy sources makes it difficult for electric utility companies to effectively implement these technologies in the power grid due to mismatches between supply and demand. Solid oxide cells are electrochemical devices that are receiving a lot attention as an effective power grid balancing technology, given...

Power generation systems based on SOFCs provide a highly efficient alternative to traditional systems. In the present study a sensitivity analysis with cell operating temperature, pressure ratio and fuel utilization as system parameters is performed on a SOFC-GT system fed by Hydrogen and Methane. Exergy losses in different system components and...

Abstract Solid Oxide Fuel-assisted Electrolysis Cells (SOFEC) are a relatively recent development as far as fuel cell research is concerned. Laboratory tests predict that they have the ability of efficiently producing hydrogen and, most importantly, at a lower cost compared to conventional high temperature electrolysis. The SOFEC mode of...

Leaders of European union and G8 have set the target of 80% reduction in greenhouse gases emissions by 2050 by decarbonizing the power and transport sector. There are several pathways to achieve this, some of them being a) use of renewable power and biomass b) improvement in transport and building energy efficiency and c) replacement of fossil...

Natural Gas Combined Cycle (NGCC) systems including Carbon Capture & Storage (CCS) and Metal Hydride (MH) based hydrogen storage seem to be an attractive technology for near future power production owing to reduced Greenhouse Gases emissions, increased flexibility and relatively high efficiency. The system design and the thermodynamic evaluation...

Solid Oxide Fuel Cells operate at high temperatures, which places stringent requirements on the ceramic materials in these devices. Optimizing the design by thermal stress minimization could increase the life expectancy of a fuel cell. In order to do this it is important to have a detailed understanding of the heat flows and temperature profiles...

Direct Internal Reforming (DIR) on Solid Oxide Fuel Cell (SOFC) anodes is often considered for fuel cells systems utilising carbon based fuels. Methane Steam Reforming (MSR) is one of the most extensively studied types of DIR. The hydrogen formed by the MSR reaction can be electrochemically oxidised in the fuel cell to produce electricity, while...

Unmanned aerial vehicles (UAV) for science missions are becoming increasingly popular in the present context. Science missions require high altitude operation and long endurance (HALE). With rising awareness of climate change phenomenon it becomes imperative to look into more efficient and more sustainable means of powering these missions. A ...

The necessary removal of organically bound nitrogen and ammonium from sewage conventionally requires energy for aeration and reduces the potential biogas production in the following anaerobic stage due to the required carbon source for de-nitrification. It has recently been demonstrated that fuel cells can generate electricity, using ammonia as...

The removal of nitrogen from wastewater is a costly and high energy demanded process. Not only in wastewater treatment facilities but also in the livestock sector nitrogen removal is costly. In this study the removal of nitrogen from wastewater by converting to ammonia to be fed as a fuel to a Solid Oxide Fuel Cell (SOFC) is treated. Ammonia is...

"As fossil fuels are depleting, polluting and an increasing source for global conflicts it has become important to find alternatives. It is essential to develop conversion chains that are able to compete with the non-renewable energy sources both technically and economically. Biomass is an upcoming flexible energy source, and has a close to...
