“…As of 2016, 96% of the total hydrogen production (i.e., ∼55 million tonnes per annum [7]) originated from fossil fuels [14]. Apart from the thermo-chemical conversion of coal and oil into hydrogen, steam methane reforming is the most widely adopted method for hydrogen production due to its cost effectiveness [15]. This is achieved by the chemical reaction between purified methane or natural gas and high temperature (i.e., 970-1120 K) and pressure (i.e., 3-25 bar) steam in the presence of a catalyst, which is typically nickel [6].…”

A paradigm shift towards the utilization of carbon-neutral and low emission fuels is necessary in the internal combustion engine industry to fulfil the carbon emission goals and future legislation requirements in many countries. Hydrogen as an energy carrier and main fuel is a promising option due to its carbon-free content, wide flammability limits and fast flame speeds. For spark-ignited internal combustion engines, utilizing hydrogen direct injection has been proven to achieve high engine power output and efficiency with low emissions. This review provides an overview of the current development and understanding of hydrogen use in internal combustion engines that are usually spark ignited, under various engine operation modes and strategies. This paper then proceeds to outline the gaps in current knowledge, along with better potential strategies and technologies that could be adopted for hydrogen direct injection in the context of compression-ignition engine applications—topics that have not yet been extensively explored to date with hydrogen but have shown advantages with compressed natural gas.

“…In such complexes, the surplus energy supplied by the RES is used for hydrogen generation by water electrolysis followed by hydrogen compression and storage. When the primary energy is in deficit, electricity needed for an end-user is generated by hydrogen fuel cells [1,2].…”

This work summarises the results of development and long-term testing of two prototype models of industrial-scale metal-hydride thermal sorption hydrogen compressors, TSC1-3.5/150 (up to 11 Nm 3 h −1 ; water cooling/steam heating) and TSC2-3.5/150 (up to 15 Nm 3 h −1 ; heating and cooling by circulating oil). Both compressors have a two-stage layout utilising LaNi 5 for the stage 1 and La 0.5 Ce 0.5 Ni 5 for stage 2, thus providing hydrogen compression from 0.35 to 15 MPa at a cooling temperature of about 20°C and a heating temperature between 150°C and 160°C. The compressors were operating for one year each and exhibited a satisfactory performance. The results of this work can be used in various medium-to-large scale hydrogen compression applications, including renewable energy systems.

“…In recent years, the demand for renewable and sustainable energy has reached a peak due to the depletion of fossil fuel resources and increasing environmental problems. Various renewable sources such as wind [1][2][3], wave [4][5][6], hydrogen [7][8][9], and solar [10][11][12] energies have been intensively investigated and commercialized. Among these, solar energy is one of the most important sources to harness energy for future applications.…”

Recently, the demand for small grid-connected photovoltaic (PV) systems has been rapidly increasing; this is due to the reduction in the costs of grid-connected storage systems as compared to those of the stand-alone ones. Notably, the performance of the solar tracking system is not only depending on the types but also the region that they are set up and used. To understand how solar tracking systems work globally, we need to know their performance in each country and even the different parts of a country. In this study, two grid-connected PV systems with 250 W solar modules were used to investigate the efficient improvement of a single-axis sun tracking system in Central Vietnam. First, a mechanical tracking device with a linear actuator and a controller was designed and then its performance was comprehensively investigated with a grid-connected PV system. In addition to evaluating the energy gain by the tracking system, this study also considered the energy consumption of the linear actuator with its controller and a small grid-connected PV system; this has generally been omitted in previous works. Experimental results indicate that the total energy consumption of the tracking system was approximately 2–8% of the energy generated by the grid-connected PV system. The maximum overall energy generation was confirmed to have increased by up to 30.3% on a sunny day upon using the proposed tracking system; further, the net energy gain by using the sun tracker was ascertained to be 15.2% in average weather conditions. Based on the success of this work, we will keep experimenting with other parts of Vietnam. Also, we will collaborate with colleagues in other countries to create a guideline for understanding and using the solar tracker regionally and globally.
