Special Issue Information

Dear Colleagues,

Hydrogen has emerged as a cornerstone of global decarbonization efforts, offering transformative potential for clean energy transitions in industries, transportation, and power generation. With nations striving to meet climate targets under the Paris Agreement, hydrogen’s versatility as a zero-carbon energy carrier (capable of integrating renewable energy surpluses and decarbonizing hard-to-abate sectors such as heavy industry and aviation) has positioned it at the forefront of energy innovation. Recent breakthroughs in electrolysis and pyrolysis have significantly advanced green hydrogen production. Concurrently, hydrogen-based power systems, including fuel cell hybrids and hydrogen-gas turbine integrations, are redefining grid flexibility in renewable-dominated markets. Despite progress, critical challenges remain, such as improving electrolyzer efficiency under variable renewable inputs, developing cost-competitive storage solutions, mitigating lifecycle environmental impacts, and enhancing specific energy, conversion efficiency, and reliability.

To address these challenges, we invite submissions to a Special Issue of Energies focusing on hydrogen production and hydrogen-based power systems, covering material science, thermal science, system integration, and related fields. This Special Issue will highlight novel designs, optimization strategies, and operation techniques for hydrogen production, storage, and system integration.

Topics of interest for publication include, but are not limited to, the following:

  • Chemical, Thermochemical and Electrochemical Hydrogen Production;
  • Electrolysis/Electrolyzer Technologies
  • Renewable Hydrogen Pathways;
  • Catalysts, Electrocatalysts, and Photocatalysts;
  • Hydrogen Carriers (e.g., LOHCs, Ammonia);
  • Advanced Hydrogen Storage Systems;
  • Fuel Cells and Applications;
  • Combustion, Heat Engines, and Thermal Management;
  • Hydrogen-Based Power Systems Integration;
  • Transportation, Marine, and Aerospace Applications.

This review article provides an overview of the use of hydrogen and tyre pyrolysis oil as fuels for homogeneous charge compression ignition (HCCI) engines. It discusses their properties, the ways they are produced and their sustainability, which is of particular importance in the present moment. Both fuels have certain advantages but also throw up many challenges, which complicate their application in HCCI engines. The paper scrutinises engine performance with hydrogen and tyre pyrolysis oil, respectively, and compares the fuels’ emissions, a crucial focus from an environmental perspective. It also surveys related technologies that have recently emerged, their effects and environmental impacts, and the rules and regulations that are starting to become established in these areas. Furthermore, it provides a comparative discussion of various engine performance data in terms of combustion behaviour, emission levels, fuel economy and potential costs or savings in real terms. The analysis reveals significant research gaps, and recommendations are provided as to areas for future study. The paper argues that hydrogen and tyre pyrolysis oil might sometimes be used together or in complementary ways to benefit HCCI engine performance. The importance of life-cycle assessment is noted, acknowledging also the requirements of the circular economy. The major findings are summarised with some comments on future perspectives for the use of sustainable fuels in HCCI engines. This review article provides a helpful reference for researchers working in this area and for policymakers concerned with establishing relevant legal frameworks, as well as for companies in the sustainable transport sector.
