1. 1. High Temperature Co-Electrolysis Model for Sector Coupling : Thermodynamic and Detailed Models of Solid Oxide Electrolysis Cells and Systems

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : FAISAL SEDEQI; [2020]
   Keywords : ;

   Abstract : The increased development of intermittent renewable energy supplies not only demands robust storage technology, but also alternative means to produce materials in ways to avoid fossil fuel consumption and make use of the increasing electricity supply. Power to gas (PtG) through solid oxide cell (SOC) co-electrolysis reactors provide an attractive manner to overcome both challenges. READ MORE

3. 2. Digital mapping of techno-economic performance of a liquid-based solar photovoltaic/thermal (PVT) system over large geographical cities around the world

   University essay from Högskolan Dalarna/Energiteknik

   Author : Santhan Reddy Penaka; [2020]
   Keywords : PVT; Liquid-based; Techno-economic analysis; Digital mapping; Large geographical cities;

   Abstract : Photovoltaic thermal (PVT) collectors are widely used to harness a large fraction of the solar spectrum to generate electricity and heat from a single collector. The circulation of the working medium will pass through the collector which cools down the PV cell temperature and also increases the water temperature, which will increase the electrical and thermal performance at the same time.

4. 3. Comparative Study of Different Organic Rankine Cycle Models: Simulations and Thermo-Economic Analysis for a Gas Engine Waste Heat Recovery Application

   University essay from KTH/Kraft- och värmeteknologi

   Author : Tihomir Rusev; [2015]
   Keywords : ORC; Waste Heat Recovery; Aspen Plus; Cascaded Cycle; Thermo-Economic; ORC Simulations; ORC Models; ORC Model Comparisons; Gas Engine Waste Heat Recovery; Hot Exhaust Gases; Multiple Waste Heat Sources; ORC Waste Heat Power Generation; Heat and Power; Combined Cycle; Siloxane;

   Abstract : Increasing the efficiency of conventional power plants is a crucial aspect in the quest of reducing the energy consumption of the world and to having sustainable energy systems in the future. Thus, within the scope of this thesis the possible efficiency improvements for the Wärtsilä 18V50DF model gas engine based combine power generation options are investigated by recovering waste heat of the engine via Organic Rankine cycle (ORC).

5. 4. Thermodynamic study of oxygen-enhanced combustion: analysis of different techniques of oxidant production

   University essay from KTH/Kraft- och värmeteknologi

   Author : Gaëlle Gosselin; [2013]
   Keywords : Membrane; PSA; Oxygen-enhanced combustion;

   Abstract : Thermal energy is an important resource for many industrial processes and is usually produced by combustion of hydrocarbon fuels with air. These processes could beneficiate from the use of oxygen-enhanced combustion (OEC), whose benefits (pollutants emissions reduction, fuel savings, productivity increase and volumes reduction) are already known.

6. 5. Thermoeconomic Analysis and Optimisation of Air-Based Bottoming Cycles for Water-Free Hybrid Solar Gas-Turbine Power Plants

   University essay from KTH/Kraft- och värmeteknologi

   Author : Raphael Sandoz; [2012]
   Keywords : ;

   Abstract : The growing worldwide energy demand and the impacts of climate change due to anthropogenic greenhouse gases emissions are among the major issues facing humanity. The global energy system, responsible for most of the greenhouse gases emissions, is therefore at the heart of global concerns. READ MORE
