Growing concerns over climate change and reliance on fossil fuels bring further attention towards sustainable energy sources. This has been amplified by the recent Russia-Ukraine war. Hydrogen from renewable sources is a promising response to the existing concerns. Newfoundland and Labrador (NL) is an encouraging location for producing hydrogen due to its natural resources. Furthermore, its geopolitical situation positions NL to be superbly situated to help alleviate the current energy crisis in Europe. To have sustainable hydrogen production and supply from NL it is essential to utilize the available resources. Therefore, this paper systematically reviews all scientific papers on NL hydrogen production, storage, and distribution. The papers are reviewed from hydrogen sources, production methods and technologies, storage methods, transportation, transmission, optimization, and sustainability perspectives across NL. Finally, some insights for academics, government, and industry sectors are provided based on our results.

In light of the intricate interconnection of current global challenges, energy security concerns, and global warming, the strategic pursuit of renewable hydrogen has emerged as a beacon of promise. Consequently, Canada, in alignment with its global environmental commitments and supported by partnerships with entities such as the European Union, is actively working to harness its significant potential in sustainable hydrogen production and distribution. This study undertakes a systematic review and bibliometric analysis of 55 scientific papers focused on hydrogen production and distribution in Canada, published up to September 2023. Firstly, a comprehensive synthesis of these papers is provided across four key dimensions: production, distribution, optimization, and sustainability. Secondly, critical insights into the evolution of hydrogen research and the collaborations shaping the field are unveiled through bibliometric analysis, employing Bibliometrix, an R-package designed for comprehensive science mapping and bibliometric analysis. The findings are intended to offer valuable insights to academic, public, and business communities, enabling them to better utilize available resources, enhance teamwork, and contribute to a more sustainable global energy landscape.

The demand for sustainable energy solutions has intensified due to the growing challenges posed by climate change and the world’s reliance on fossil fuels. Recently, in response to these challenges, policymakers came together to utilize the Western United States distinct geographic advantages and abundance of natural resources to form the first hydrogen hub partnership in the country, called Western Inter-States Hydrogen Hub. Therefore, this work offers insights and recommendations to the stakeholders involved in Western Inter-States Hydrogen Hub to enhance data-driven decision making through a comprehensive examination of the scientific literature with an emphasis on hydrogen’s pathways as a workable solution, particularly based on renewable sources. To that end we compare the economic, environmental, and social effects of various hydrogen production pathways to unfold their sustainability. Finally, we offer some recommendations for scientific, policymaking, and practitioner readers.
