The intention of Renewable Energy Technology – Advanced course is to give students a deeper knowledge and understanding on technological aspects of most promising and rapidly developing renewable energy systems. This course goes into details of three main renewable energy systems: Solar Energy systems (photovoltaics and thermal), Bioenergy systems, Wind Energy systems; and covers Energy Storage. This course aims to develop the knowledge and skills of students to analyze the potential of appropriate renewable resources and to deliver renewable energy solutions to meet the societal energy demand.

Students joining this course should have a basic knowledge in Solar, Wind and Bioenergy conversion technologies as well as an understanding on potential resources. The prerequisite for joining this course is the successful completion of the Renewable Energy Technology introductory course (MJ2411).

These three areas of renewable systems have attracted particular interest in recent years where energy supply and climate change are of critical concern. The selection of these three areas of renewable systems and energy storage is a follow-up from the previous course. These three renewable energy resources will not solve major energy issues in the short term, but they will most likely be vital ingredients of future energy mix worldwide.

Bioenergy, particularly the biomass-based fuels have attracted much interest due to their ample supply in some countries and favorable environmental characteristics, if properly managed. Bioenergy systems would be highly important in the holistic renewable energy picture as bioenergy can provide system needs of energy storage cost effectively. Biomass is an indigenous energy source, available in most countries and its multifaceted applications diversify fuel-supply, which in turn leads to a more secure energy supply. Biomass is available either through natural plant growth processes, or as a by-product of human activities, i.e. organic wastes. There is however a growing concern about energy crops competing with food production, so researchers are now focusing on the second generation fuels by considering feedstocks. The effective capture and continued sustainability of this renewable resource requires a new generation of biomass power plants with high fuel energy conversion. The topics covered here are Applied Combustion, Fluidized Beds, and Chemical Equilibrium & Kinetics.

Solar energy on the other hand has so far been more of a niche market development (e.g. microscale distributed generation via photovoltaics, solar hot water heating, etc.) owing to high investment costs, but it has a large potential in the future. Solar thermal systems can help significantly reduce fossil based heating/cooling needs as the demands can be covered by this renewable source. Solar thermal is also highly promising for kW and MW scale electric power generation via concentrating solar power (CSP) systems; here steam Rankine cycles are commercially available, and more efficient Brayton cycles may soon be on the horizon. This course treats CSP technologies in detail.

The importance of wind turbine as a commercial technology in the current energy systems has already made its justification; its role in the reduction of greenhouse emissions has been identified by governments and energy planners. This subject has acquired a great improvement from the engineering side. A significant change in the economic viability of wind energy has occurred as a consequence of technology improvements, while social acceptance is rising among the energy industry and the general public due to the steady increase in environmental awareness and to the successful information dissemination of the Kyoto protocol. This course is intended to provide a thorough and highly accessible introduction to the cross-disciplinary field of wind turbine engineering and technology, with focus on topics like small-scale and hybrid systems.

Energy storage is essential in securing a stable electricity grid and thermal network (district heating and cooling) when integrating intermittent renewable energy resources to the energy system. Electricity and thermal energy peak shaving and load shifting are two of the main outcome of the storage systems; a non-exhaustive list of benefits are 1. Energy arbitrage, 2. General capacity deferral, 3. Transmission and distribution deferral, 4. Ancillary services, 5. Reduction of energy curtailment. Here, we will have a closer look at the storage components from an engineering perspective.
