“…On average, the HHO-CNG mixture is responsible for a 36.14% decline in economic cost associated with CO 2 emission, in comparison with gasoline. According to the International Energy Agency, alongside other activities [51][52][53][54][55][56][57], the presented considerations are in line with Net Zero Emissions according to the 2050 scenario [58]. Figure 8 demonstrates the variation in CO content with respect to engine speed.…”

Road transportation has received the attention of researchers due to its higher carbon footprint. Alternative fuels present major advantages in terms of environmental sustainability. For this reason, an enviro-economic analysis of alternative fuels carries great significance. However, scarce attempts have been rendered in order to ascertain the impact of a hydroxy gas (HHO) and compressed natural gas (CNG) mixture on sustainable environmental development. The current study addresses this issue by employing an HHO–CNG mixture and gasoline in spark ignition (SI) engines for the purposes of performance and environmental pollutants measurement. Then, engine emission data were substituted for Weibull distribution in order to establish suitability for 50 and 95% confidence intervals (CIs). The mixture outperformed gasoline in terms of brake-specific fuel consumption (BSFC) and emission contents. On average, hydroxy gas with CNG produced 10.59% lower oxides of nitrogen (NOX) comparative to gasoline. Finally, the enviro-economic analysis also turned out to be in favor of the hydroxy gas mixture owing to a saving of 36.14% in USD/year due to 27.87% lower production of carbon dioxide (CO2) emission.

“…However, while the long-term goals are clear, the pathways to achieving carbon emissions reduction targets for buildings are less so. To keep cumulative carbon emissions of the global building stock in check, the annual global renovation rate must increase from (the current) 1% to 5%, and all new construction must be carbon neutral by 2040 in terms of both operational and embodied energy use 6,7 . For The United Kingdom, this translates into a retrofit rate of 1.5 homes every minute from now until 2050 8 .…”

Carbon reduction technology pathways for existing buildings in eight cities

et al. 2023

We work with policymakers in eight cities worldwide to identify technology pathways toward their near- and long-term carbon emissions reduction targets for existing buildings. Based on policymakers’ interests, we define city-specific shallow and deep retrofitting packages along with onsite photovoltaic generation potential. Without further grid decarbonization measures, stock-wide implementation of these retrofits in the investigated neighborhoods reduces energy use and carbon emissions by up to 66% and 84%, respectively, helping Braga, Dublin, Florianopolis, Middlebury, and Singapore to meet their 2030 goals. With projected grid decarbonization, Florianopolis and Singapore will reach their 2050 goals. The remaining emissions stem from municipalities not planning to electrify heating and/or domestic hot water use. Different climates and construction practices lead to varying retrofit packages, suggesting that comparable technology pathway analyses should be conducted for municipalities worldwide. Twenty months after the project ended, seven cities have implemented policy measures or expanded the analysis across their building stock.
