Modeling of a Renewable Energy System, Experiential Innovation and Technology Centre

Hua, Charles 23 September 2008 (has links)
Energy consumption has been increasing rapidly over the last few decades. In 2003, Ontario’s energy needs were in the order of 155.1 TWh and are expected to increase to 168.9 TWh by 2014. This will create an increased demand for power generation, electricity distribution, resources, as well as the generation of pollution. Thus, there is a requirement for infrastructure renewal and expansion within a sustainable energy management framework. With respect to stationary power requirements, there are many solutions available such as consumption reduction and overall energy efficient. Demand side management and energy conservation will mitigate the problem, is it likely that more power generation will be required. A distributed generation system is most desirable as there is relief for the electricity distribution grid. Key to this study is the examination of the potential for the distributed energy system to produce electricity for the facility while also producing hydrogen to support a small fleet of vehicles for use at the facility, demonstrating an integrated energy system. The results for the fleet of vehicles are preliminary only, while most of the focus was put into the energy system of the facility. The application of this distributed system will be in the commercial/industrial sector where a technology center will be the primary load while supplying power to the grid when excess power is generated. There are many sources of distributed energy available to be used in distributed generation systems ranging from diesel generators to wind turbines, the various green generation technologies have been evaluated during this study. The evaluation takes into account cost, efficiency, size, and availability. This study has shown that such a facility can produce emissions free distributed electricity in a Net Zero manner with an electrical grid connection, as well as economically support refuelling a fleet of hydrogen fuel cell vehicles. The selected systems have been modeled and sized to demonstrate operating conditions and assess the energy/power flow. Different scenarios were simulated to show how the system will react to intermittent environmental conditions, such as wind speed.

Hydrogen future

Whittaker, Alexander January 2015 (has links)
Hydrogen electrolysis has gone through a number of stages in research and applications. From what we can see from this report, there are several ways of producing hydrogen electrolysis, and several applications. The main purposes of this report however, is not to describe what hydrogen electrolysis is and its applications. Research and experiments has already proven that it is a functioning technology. The aim is to gather the necessary information, both theoretically and practically to be able, from a technical and business point of view analyze if this in fact is a realistic solution. To maintain a system of sustainable energy has always been an attractive market and there has existed a number of technologies that has had their share of the fame. However, most of these solutions have shown not to be viable, lucrative or technically scalable. Hence, the important issue to address is whether this is a solution worth investing in. The information gathered for the theory is based on technical reports, academic scripture and literature. All of which can be back tracked to its original source. The practical test is done by using a test kit made for universities and other institutes to better understand how hydrogen electrolysis works. The materials used are all scientifically acceptable according to the theories and technologies surrounding hydrogen electrolysis. Hence, the data gathered from the test kits are all accurate according to current research.

Exploring the Feasibility of Achieving Energy Self-sufficiency ??? A Residential Electricity Case Study in Ontario

Li, Hang January 2013 (has links)
As energy security and climate issues are emerging as global concerns, it is commonly agreed that a transition from a conventional centralized energy system, which is largely based on combustion of fossil fuel, to a more sustainable decentralized energy system that includes mainly renewable energy sources is necessary and urgent. Due to the highly variable geographical qualities of renewable energy sources, spatial energy planning is becoming essential. This study aims to address the challenges in linking spatial modelling with assessment of regional energy consumption and renewable energy supply potential. A novel approach for exploring the feasibility of achieving energy self-sufficiency through matching energy deficit areas with energy surplus areas is proposed. A method for energy deficit and surplus area matching is developed and implemented in a VBA- based tool that serves as a decision-support tool by exploring possible future deployment of renewable energy in decentralized ways. Achieving Ontario residential electricity self-sufficiency through solar PV energy on an annual basis is explored as a case study. The results show that it is technically feasible for Ontario to be residential electricity self-sufficient through the development of solar PV energy with energy deficit areas within the region getting energy supply from nearby energy surplus areas. The case study implies that regional residential electricity self- sufficiency is achievable and it is useful for planners and policy makers to bear the regional energy deficit-surplus matching idea in mind when making urban and energy plans.
