Abstract:

The prospects for renewable energy are enhanced through the use of hydrogen energy systems in which hydrogen is an energy carrier. As easily accessible fossil fuel supplies become scarcer and environmental concerns increase, hydrogen is likely to become an increasingly important chemical energy carrier. As the world’s energy sources become less fossil fuel-based, hydrogen and electricity are expected to be the two dominant energy carriers for the provision of end-use services, in a hydrogen economy. Thus, hydrogen energy systems allow greater use of renewable energy resources. In this presentation, the role of hydrogen as an energy carrier and hydrogen energy systems, and their economics, are described and reviewed.

There are many commercial processes for producing hydrogen from fossil fuel and non-fossil fuel sources (including renewables). Technologies for the storage and distribution of hydrogen exist. Technologies are developing for utilizing hydrogen as an energy carrier, especially in transportation. The technologies needed for hydrogen energy systems are undergoing much research and development.

Abstract:

The interest in zero carbon building developments is increasing year by year. This makes it important to maximize the renewable power outputs and thus favors the use of hybrid generating systems. Combined active and passive solar design is an evolving science in building technology. Traditionally, building facade is one crucial element in architecture. Nowadays, it has escalating importance in services engineering owning to its significant influence on the engineering system performance and energy use. Building integrated solar devices may be installed either at the building façade or on the roof. The system can be designed as invisible, aesthetically appealing, or appearing as an architectural concept. Advances in the development of multi-functional photovoltaic/thermal (PV/T) facades may provide an important stimulus for architectural expression. On the other hand, the design of extensively-glazed building is a world-wide architectural trend. At this end, the PV ventilated glazing technology offers substantial energy saving opportunities through air conditioning load reduction, more favorable daylight penetration, and solar energy utilization. On the other hand in the liquid-flow window option, a thermosyphon-induced liquid stream flows within the cavity to the heat exchanger for feed water pre-heating. The building integrated active and passive solar designs then ask for the consideration of all building components and services systems at one shot, well at the project commencement stage. In other words, site planning, aesthetic design, system equipment and construction material selection, financing, construction, commissioning, and long term operation and maintenance have to be well coordinated. These become alternative challenges to be overcome.

Abstract:

Do we need energy or exergy? Amount of exergy in energy carriers is very different and prices include value of quantity and not the quality of energy. Exergy is measure for quality of energy, because the only part of energy available to do work is exergy. For different purposes we need energy with different amount of exergy: for heating and cooling energy mixture between small amount of the exergy and large part anergy is needed. Transition to sustainable energy system, without GHG emissions, based on RE, open the questions how to evaluate exergy from solar energy. Solar energy in all form (irradiation, water flows, wind, and biomass) consists from nearly 100% of exergy. Solar energy is for free, conversion systems are not. To exploit at maximum the present infrastructure there is common agreement that we need sustainable energy system with four main energy carriers: electricity, gaseous, liquid and solid fuels.

Our vision is the new Sustainable Energy System (SES) based on the biomass carbon recycling using solar and planetary energy for electricity and hydrogen production. SES is based on the existing infrastructure and known chemical processes. With regards to availability of renewable energy resources (RES) it is unrestricted in comparison to present fossil fuels use. The proposed SES consists of the three main energy carriers: electricity, synthetic methane (CH4) and synthetic methanol (CH3OH).

Session Introduction

Chul Hee Jo

Inha University, South Korea

Title: Interaction analysis of multi-arrangement in tidal current energy farm
Speaker
Biography:

Professor Jo, Chul Hee has finished his Mater degree at Stevens Institute of Technology, USA in 1985 and Ph.D in Ocean Engineering at Texas A&M University in 1991. After working for Intec Engineering, Houston USA and Hyundai Heavy Industries, Korea from 1992 to 1997, he has joined to Inha University in Korea. His main research area is tidal current energy and he has been involved in many government advisory bodies and committees in ocean energy policy, development planning and research since 1998. Being the first author in ocean energy text book written in Korea, he has published more than 200 journal and conference papers with more than 80 patents registered and pending in tidal current energy field. Prof. Jo has been conducted numerous government and industry projects developing tidal current generation system. He is currently the director of the Ocean Energy and Environmental Research Center and the vice president for KSNRE (Korean Society for New and Renewable Energy) and the Executive committee member for AWTEC (Asian Wave and Tidal Energy Conference). focusing.

Abstract:

A focus on renewable energy has been increased as the global warming problem rises. The tidal current power, one of ocean energy resources is acknowledged to have a great potential due to its high energy density with continuous and predictable advantages. Tidal energy technologies can be applied effectively in areas having regular current distribution such as in the ocean with tides and also in rivers with current. To extract energy in a large scale farm, a large number of devices are to be installed for feasible commercial operation. Studies have been conducted throughout the world to find the interaction effect for multi arrayed tidal current devices. The total power production rate of a farm is affected by the turbine arrangement and it interaction. To maximize the power production in the tidal farm equipped with horizontal axis tidal turbines, it is important to understand the wake behavior and its range of influence to downstream. The related papers have been introduced by many researchers with CFD and experimental approaches together with limited experiments. However, the results are quite different from each other. These are due to various boundary and initial conditions with various design factors applied. Also the experiment results vary from each other. In this research, published papers relating to interference effects for multi array of tidal turbines are compared and evaluated. From the analysis, the reasonable velocity recovery rate with axial gaps considering the wake effect downstream is suggested.

Mina Bahrami Gholami

University of Auckland Energy Center, New Zealand

Title: Potential solar and wind power expansion in the New Zealand Network
Speaker
Biography:

Mina Bahrami Gholami is a PhD candidate of economics at the University of Auckland. With knowledge on both econometric and mathematical methods, she is passionate about environmental issues including topics on mitigating emissions and renewable energies.

She has nearly completed her doctoral research on evaluating the opportunities for solar PV generation, and the impacts of large solar and wind power on the New Zealand electricity market. Applying agent based model, using the solver SWEM that is developed by the Energy Center, she simulates power market to answer the open questions about the effects of intermittent power extension on nodal and national prices.

Her background goes back to environmental economics. For her Master’s thesis, she conducted a comparative study on greenhouse gas emissions in OECD and OPEC countries using econometric approach, panel data.

Abstract:

Renewable generation, solar and wind, has constantly increased over the last decades. Increasing the share of renewable generation, it is well known that power price is likely to reduce in short-run due to the merit order effect. In long term, the effect also depends on changes in new capacity investments. Previous studies examine the effect of intermittent energies in different electricity markets. For a hydro-based system such as New Zealand, increasing the share of variable resources is more important as the main supply is changeable and depends on climatic conditions. Wind power expansion for this network is well studied by Browne et al. (2015); however, they do not consider solar power in their model. New Zealand seems to be reach enough to access adequate sun radiation for the purpose of power generation, particularly in the North Island. Therefore, the contribution of this study is introducing large solar power into the system. We extend the literature by simulating the power market, using an agent-based model, in order to answer the question of whether wind extension is the best solution in terms of the impacts on electricity price and dispatch or the solar aggregated wind power scenarios would better fits the existing network. We investigate this issue for the case of New Zealand as a small and pure hydro-based network yet the methodology is applicable for other power networks as well.

Speaker
Biography:

Joop van Deelen is senior scientist at TNO with 20 years of R&D experience and over 60  publications. He has covered a broad range of thin film PV related topics including deposition technologies, optics, front contacts, R&D strategy and business case development. In addition to his R&D activities, he consults companies on technical and strategic level in various parts of the world.

Abstract:

R&D has had a major impact in the rise of renewable energy. In addition to basic research, dedicated development enables the increase of the energy conversion efficiency. However, in the competitive market economy, companies have to make strategic choices about the viability of innovation directions. For this reason scientific, technical and economic aspects need to be combined to make smart choices in innovation.

We present several innovation routes in which Solliance has activities: improved transparent contacts, reduction of CIGS layer thickness, cheap absorber layers and tandem cells. Each innovation route has its specific advantages, but is connected to equally specific requirements to the layers surrounding the absorber, which need to be addressed. The efficiency increase and the cost associated with the technological solutions result in a balance, which is the net advantage.

For instance, thinning of the CIGS layer brings a significant cost reduction [1,2]. However, light management technology [3] and enhanced surface passivation is needed to keep the efficiency as high as possible. This leads to a range of innovation scenarios including various device designs and material choices, which will be detailed, from which the best choice becomes apparent. A vital element is the interdependence of all these factors. For different absorber layer thicknesses, different preferred adjacent technologies emerge for passivation and light management.

For improved transparent contacts, we have modeled and demonstrated the benefit by adding metallic grids on the TCO, as shown in figure 1 [4-6]. Here we also discuss the technical challenges, the economic perspective and the trade-offs involved.

One of the spearheads of modern thin film PV research is the development of perovskite solar cells. It gives the promise of cheap and abundant source materials and low-cost coating technologies to make devices. However, in addition to the limited life time, we should clearly envision the impact of such a new material and the impact on the cost structure. In addition, the promise of very high efficiency in the case of large area tandem cells can be regarded as a mid- to long-term strategy and also here the technical and economic pros and cons are reviewed.
