Future of Electric and Hydrogen Cars and Trucks: An Overview

Energies, Journal Year: 2023, Volume and Issue: 16(7), P. 3230 - 3230

Published: April 3, 2023

The negative consequences of toxic emissions from internal combustion engines, energy security, climate change, and costs have led to a growing demand for clean power sources in the automotive industry. development eco-friendly vehicle technologies, such as electric hydrogen vehicles, has increased. This article investigates whether vehicles will replace future. results showed that fuel-cell cars are unlikely compete with cars. is due advancements charging infrastructure, which becoming more cost-effective efficient. Additionally, technical progress battery (BEVs) expected reduce market share (FCEVs) passenger vehicles. However, significant investments been made Many ongoing seem follow sunk cost fallacy, where decision-makers continue invest an unprofitable project their already invested resources. Furthermore, even megawatt charging, trucks than battery-powered trucks. use cases also much limited, running expenses higher compared Hydrogen may be beneficial heavy transport remote areas. it remains seen if niche markets large enough support truck commercialization economies scale. In summary, we believe not trucks, at least before 2050.

Current status of developed electrocatalysts for water splitting technologies: from experimental to industrial perspective

Nano Convergence, Journal Year: 2025, Volume and Issue: 12(1)

Published: Feb. 6, 2025

Abstract The conversion of electricity into hydrogen (H 2 ) gas through electrochemical water splitting using efficient electrocatalysts has been one the most important future technologies to create vast amounts clean and renewable energy. Low-temperature electrolyzer systems, such as proton exchange membrane electrolyzers, alkaline anion electrolyzers are at forefront current technologies. Their performance, however, generally depends on costs system efficiency, which can be significantly improved by developing high-performance enhance kinetics both cathodic evolution reaction anodic oxygen reaction. Despite numerous active research efforts in catalyst development, performance electrolysis remains insufficient for commercialization. Ongoing innovative an understanding catalytic mechanisms critical enhancing their activity stability electrolyzers. This is still a focus academic institutes/universities industrial R&D centers. Herein, we provide overview state directions H production. Additionally, describe detail technological framework production utilized relevant global companies. Graphical

Enhancing Energy Efficiency in Buildings through PCM Integration: A Study across Different Climatic Regions

Buildings, Journal Year: 2023, Volume and Issue: 14(1), P. 40 - 40

Published: Dec. 22, 2023

In the quest for sustainable and energy-efficient building solutions, incorporation of phase change materials (PCMs) into envelopes emerges as a groundbreaking strategy. PCMs, renowned storing releasing thermal energy during transitions, stand promising avenue to curtail consumption while enhancing performance. This study rigorously explores potential savings comfort benefits achievable through PCM integration envelopes. Multiple simulations are conducted on residential model in diverse locations, including Irbid, Amman, Aqaba Jordan, city Oradea Romania, utilizing EnergyPlus simulation tool embedded DesignBuilder software v7.0.2.006. The results reveal that BioPCM®, derived from renewable biomass, significantly elevates performance owing its heightened latent heat fusion. Optimal outcomes materialize with melting point 23 °C, configuration closer interior surface, thickness 37.1 mm. underscores superior moderate climates (Irbid Amman) compared hot-dry (Aqaba) cold-wet (Oradea, Romania). Financially environmentally, incorporating Amman demonstrates annual 5476.14 kWh, translating cost reduction 1150 USD/year, decrease GHG emissions by 2382.31 kgCO2eq. estimated payback period external walls is four years, robustly emphasizing feasibility multifaceted this solution.
