This paper presents an energy management algorithm based on an extended proportional integral derivative (PID) controller. To validate the proposed algorithm comprehensive simulation models were developed including a longitudinal dynamics-based vehicle model an ampere–hour integration-based power battery model a fuel cell model based on the Nernst equation and a hydrogen consumption model. An economic assessment was conducte Read More

This manuscript contributes to understanding the role of hydrogen in different materials emphasizing polymers and composite materials to increase hydrogen storage capacity in those materials. Hydrogen storage is critical in advancing and optimizing sustainable energy solutions that are essential for improving their performance. Capillary arrays which offer increased surface area and optimized storage geometries present a promising avenue f Read More

To address the challenges of multi-energy coupling decision-making caused by the complex interactions and significant conflicts of interest among multiple entities in integrated energy systems an energy management strategy for integrated energy systems with electricity heat and hydrogen multi-energy storage is proposed. First based on the coupling relationship of electricity heat and hydrogen multi-energy flows the architecture of the integrated energy Read More

The increase in industrial production and energy consumption has led to excessive exploitation of non-renewable resources resulting in serious environmental problems such as greenhouse gas emissions. In response there’s a growing investment in renewable energies such as hydroelectric wind and solar power. However these sources are unable to fully meet demand leading to imbalances between consumption and production. An emerging solution to thi Read More

The ability for existing burners to operate safely and efficiently on hydrogen-blended fuels is a primary concern for the many industries looking to adopt hydrogen as an alternative fuel. This study investigates the efficacy of increasing fuel injector diameter as a simple modification strategy to extend the hydrogen-blending limits before flashback. The collateral effects of this modification are quantified with respect to a set of key performance criteri Read More

The primary motivation of the present study is to mitigate the severe impact of ongoing energy resource shortages while offering clean and sustainable energy carriers such as hydrogen and ammonia. The present system mainly encompasses water splitting and the Haber-Bosch (HB) processes for green hydrogen and ammonia synthesis using solar and wind power respectively. Pointwise quantification analyses are conducted to quantify the power Read More

he use of hydrogen (H2) as a substitute for fossil fuel which accounts for the majority of the world’s energy is environmentally the most benign option for the reduction of CO2 emissions. his will require gigawatt-scale storage systems and as such H2 storage in porous rocks in the subsurface will be required. ccurate estimation of the thermodynamic and transport properties of H2 mixed with other gases found within the storage system is therefore essential for Read More

The decarbonization of hard-to-abate industries is crucial for keeping global warming to below 2◦C. Green or renewable hydrogen synthesized through water electrolysis has emerged as a sustainable alternative for fossil fuels in energy-intensive sectors such as aluminum cement chemicals steel and transportation. However the scalability of green hydrogen production faces challenges including infrastructure gaps energy losses excessive power consumption Read More

Recently worldwide the attention being paid to hydrogen and its derivatives as alternative carbon-free (or low-carbon) options for the electricity sector the transport sector and the industry sector has increased. Several projects in the field of low-emission hydrogen production (particularly electrolysis-based green hydrogen) have either been constructed or analyzed for their feasibility. Despite the great ambitions announced by some nations with respe Read More
