Advanced Hydrogen Energy Systems and Hybrid Energy Storage

Dear Colleagues,

Petroleum-derived liquid fuels have been used for many years to meet energy needs in the transportation and industrial sectors. The easy integration of petroleum-derived fuels into internal combustion engines, and their limited reserves, combined with the growing demand for liquid fuels, have increased dependence on petroleum and shaped the global economic landscape. Increasing environmental concerns stemming from fossil fuel consumption in developed countries, and the desire of developing countries to reduce volatility in fossil fuel prices have necessitated a shift toward new and renewable energy sources. Decarbonization is a major challenge, particularly for the energy storage sector. To reduce climate impact, the sector will need to leverage more tools, such as radical new technologies and sustainable fuels at scale.

For many years, research has been conducted to address the need for new and renewable fuels, and efforts to develop useful models are ongoing. However, the supply of inedible raw materials and the cost of production methods sustain dependence on oil. At this point, hydrogen, which has been researched and known in the past and is considered a significant energy-dense resource for the near future, comes to the forefront. Significant progress has been achieved in the transportation sector, especially in recent years, concerning sustainability. Hydrogen is gaining notable interest among alternative fuels that could assist countries in reaching their emissions reduction and sustainability objectives. Until recently, hydrogen fuel was not considered a practical option for the transportation and aviation sectors. However, advances in cryogenic hydrogen fuel technology have significantly increased its commercial potential. New technologies now allow hydrogen to be stored in liquid form, providing advantages such as higher energy density and smaller storage volumes. At this point, the development of technologies that will enable the widespread use of hydrogen as an efficient energy source by integrating it into single and hybrid systems will help fill the energy gap and provide tremendous benefits in protecting the environment for future generations. With this motivation, advanced technological production and widespread use of hydrogen will provide a breakthrough. However, there is a gap in the literature regarding the current status and future developments.
