Abstract

Urban flooding is increasingly concerning due to climate change and rapid urbanization. Factors such as intensified rainfall, urban sprawl, and reduced permeable surfaces heighten flood risks, making efficient stormwater management crucial. This study focuses on developing a Decision Support System (DSS) to optimize green infrastructure (GI) placement in urban areas, aiming to enhance stormwater infiltration and reduce flood risks under climate change scenarios. The research reviews current strategies for GI planning and DSS in urban flood management. By integrating GIS tools, hydrological models, and climate data, the DSS identifies ideal locations for GI measures like rain gardens, bioswales, and permeable pavements, promoting effective stormwater management while addressing climate change. Hydrological models simulate stormwater behavior under varying rainfall conditions, and GIS maps potential GI sites within urban areas. Simulations of future extreme rainfall events assess GI performance under changing climate conditions. Results show significant reductions in stormwater runoff and flood risks, particularly in areas with high impervious surfaces. Challenges such as space constraints in dense urban areas, scalability of GI solutions, and long-term maintenance are discussed. The study concludes that integrating GI with traditional stormwater systems offers a comprehensive approach to urban flood mitigation, with the DSS serving as a key tool for urban planners and policymakers.

Abstract

This study explores the application of green hydrogen technology for industrial decarbonization, focusing on its techno-economic and environmental feasibility. A quantitative approach was used, incorporating system modeling of a solar-based hydrogen production system combined with electrolyzers. The techno-economic assessment involved calculating the Levelized Cost of Hydrogen (LCOH), estimating capital and operational expenditures (CAPEX and OPEX), and evaluating the system's energy efficiency and hydrogen output. The environmental impact was analyzed using Life Cycle Assessment (LCA), comparing the carbon footprint of green hydrogen with fossil-based hydrogen. The results reveal that green hydrogen can reduce carbon emissions by up to 60% compared to fossil hydrogen, primarily due to the use of renewable energy for production. Additionally, the study found significant improvements in energy efficiency as electrolyzer performance and solar capacity increased. The LCOH is expected to decrease steadily as solar panel and electrolyzer prices continue to fall, enhancing the competitiveness of green hydrogen in the energy market. The findings also highlight the potential for heavy industries, such as cement and steel production, to transition from fossil fuels to green hydrogen, contributing to a cleaner industrial energy mix. This transition presents both environmental and economic benefits, with long-term savings from reduced fossil fuel dependency and lower production costs.
