Applications & Pathways

The signing of the Paris Agreement in 2016 established the goals of countries around the world for the transition from traditional fossil energy to sustainable energy in the 21st century. Reduce carbon emissions using new sustainable energy sources while safeguarding the energy needs of social development. The advantages of hydrogen fuel cell vehicles such as no carbon emissions long battery life and short hydrogenation time make them the developmen Read More

Retrofitting regional turboprop aircraft with hydrogen (H2)-electric powertrains using fuel cell systems (FCSs) has gained interest in the last decade. This type of powertrain eliminates CO2 NOx and fine particle emissions during flight as FCSs only emit water. In this context the “Hydrogen Aircraft Powertrain and Storage Systems” (HAPSS) project targets the development of a H2-electric propulsion system for retrofitting Dash 8- 300 series aircraft. The purp Read More

Indonesia faces mounting challenges from climate change and environmental degradation underscoring the need for sustainable transportation solutions. This study evaluates factors influencing the adoption of Hybrid Electric Vehicles (HEV) Battery Electric Vehicles (BEV) and Hydrogen Fuel Cell Vehicles (HFCV) using Multi-Criteria Analysis (MCA) and Total Cost of Ownership (TCO) approaches. Eight key factors were analyzed: safety operational and mainte Read More

This paper presents an improved Equivalent Consumption Minimization Strategy (ECMS) designed to optimize energy management for the hybrid hydrogen fuel power setups in multirotor drones. The proposed strategy aims to reduce hydrogen consumption and enhance the performance of the system consisting of Proton Exchange Membrane Fuel Cells (PEMFCs) and lithium batteries. Multirotor drones experience rapid power fluctuations due to their agile Read More

This paper aims at investigating clean hydrogen production from the large size (14 GW) hydroelectric power plant of Itaipu located on the border between Paraguay and Brazil the two countries that own and manage the plant. The hydrogen produced by a water electrolysis process is converted into ammonia through the well-known Haber-Bosch process. Hydraulic energy is employed to produce H2 and N2 respectively from a large-scale electrolysis syst Read More

The rapid growth of the global population and industrial activities has significantly increased greenhouse gases (GHGs) emissions with projections indicating a temperature rise of 3–6 ◦C by 2050. Urgent action is needed to limit global warming to 1.5 ◦C above pre-industrial levels. Hydrogen with its high energy density and compatibility with renewable energy systems presents a promising clean energy solution to mitigate GHGs emissions. Yet its widespre Read More

The use of highly efficient cogeneration systems fueled by pure hydrogen such as Solid Oxide Fuel Cells (SOFCs) in the residential sector is one of the new frontiers for achieving the net zero greenhouse gas emissions tran sitions. The lack of experimental studies in this area prompted the authors to propose the present paper. It refers to hydrogen-fueled SOFC 1 kW-sized integrated into the plant system of a single-family villa configurated as a nearly Zero Read More

The paper discusses some of the requirements drivers and resulting technological paths for manufacturers to develop hydrogen combustion engines for use in two types of market application – onroad heavy- and light-duty. One of the main requirements is legislative certainty and this has now been afforded – at least in the major market of Europe – by the European Union’s recent adoption into law of tailpipe emissions limits specifically designed to encoura Read More

This paper evaluates the potential impacts of introducing low-carbon intensity hydrogen technologies in two oil refineries with different complexity levels emphasizing the role of hydrogen production in reducing CO2 emissions. The novelty of this work lies in three key aspects: Comprehensive system analysis of refinery complexity using real site data integration of low-carbon Hydrogen technologies long-term and short-term strategies. Two Colombian refi Read More

Hydrogen (H2) offers a green medium for storing the excess from renewables production instead of dumping it thus being crucial to decarbonisation efforts. Hydrogen also offers a storage medium for the grid’s cheap electricity to be used during grid peak demand or grid power cutoffs. Funded by the Scottish Government’s Emerging Energy Technologies this paper presents the design and performance analysis of a hydrogen uninterruptible power suppl Read More
