An assessment methodology for enviro-economic justification of low and zero carbon technologies
The imperative to reduce the carbon footprint of buildings will inevitably require adopting higher levels of insulation and on-site low and zero carbon technologies. This will significantly increase the embodied carbon of materials and products that have been used in the building. With buildings …

Analysis and optimization of the Graz cycle : a coal fired power generation scheme with near-zero carbon dioxide emissions
Humans are releasing record amounts of carbon dioxide into the atmosphere through the combustion of fossil fuels in power generation plants. With mounting evidence that this carbon dioxide is a leading cause of global warming and with energy demand exploding, it is time to seek out realistic power …

Life Cycle Optimization of a Zero Carbon Building for CO2e, Energy, and Cost Using Stochastic Controls for an Energy System Integrating a Heat Pump, Solar Air Wall, PV, and a Smart Grid-integrated Thermal Storage (SGTS) Hydronic Battery
The life cycle optimization (LCO) of zero carbon buildings (ZC) was examined, using a laneway house built with photovoltaic and solar air wall (SAW) renewable energy collection, air-to-water heat pump, smart grid-integrated thermal storage (SGTS) hydronic battery with an internet-connected …

Economic analysis of international climate cooperation
… to study international cooperation on net-zero carbon emission among sixteen geographic regions. I find that achieving net-zero emission by mid-century reduces global social welfare loss by up to 35%, accounting for the emission reduction cost. However, I show that this international …

The role of long duration energy storage in decarbonizing power systems
Plans for a decarbonized power system call for a significant increase in generation from variable renewable energy (VRE) sources, i.e. wind and solar. Yet, the intermittency of these resources introduces new challenges in operating the grid, including the need for sufficient operating flexibility …

A study on the impact of global replacement of fossil fuel based electricity generation, transportation and domestic heating with nuclear generated electricity using a modified VENSIM DICE model
… on declared national target year to attain net-zero carbon status, simulations were carried out based on parametric targets. Simulations results indicate that replacing all FF generation plants, vehicles and heaters would reduce CO2 emissions roughly 25%. For a net zero target of 2060, CO2 …

Sustainable Retrofitting in the 21st Century: Reviewing the Impact of Municipal Policy on Rental Property Owners
… total greenhouse gas emissions. Achieving net-zero emissions by 2050 requires that 85% of existing buildings be retrofitted to a zero-carbon-ready state. Rental properties, often less energy efficient than owner-occupied homes, must also be improved to meet these targets. This study …

Distinct roles for energy storage and transmission infrastructure in a renewables-based electric power system
… low cost is one of the main hurdles to realizing zero-carbon electricity generation. In this study, we analyze the roles of energy storage systems (ESS) and transmission infrastructure in the cost-optimal deployment of a renewable electricity grid in the United States. We find that storage and …

System Dynamic Analysis to Evaluate the Socio-Economic Impact of the Energy Transition of Singapore to Achieve Net Zero Emissions by 2050
Singapore has pledged to achieve net zero carbon emissions by 2050. However, due to the country's limited land and lack of natural resources, the transition to net zero emission is a challenging journey. Singapore has chartered an energy transition plan to help the country navigate into a lower …

Optimization of heterogeneous bio-based catalysts and synthesis of inorganic equivalent for large-scale biodiesel production
… drawbacks. Fossil fuels, unlike biodiesel, are carbon rich and hence on combustion, releases excessive amounts of CO2, NOX and SOX leading to global warming. In this research, waste cooking oil (WCO) and ethanol were used as the main raw materials to produce biodiesel known to have net zero …
