This study presents sector-coupled PyPSA-Earth: a novel global open-source energy system optimization model that incorporates major demand sectors and energy carriers in high spatial and temporal resolution to enable energy transition studies worldwide. The model includes a workflow that automatically downloads and processes the necessary demand supply and transmission data to co-optimize investment and operation of energy systems of cou Read More

This study explores the feasibility parameters of a potential investment plan for injecting “green” hydrogen into the existing natural gas supply network in Greece. To this end a preliminary profitability optimization analysis was conducted through key performance indicators such as the cost of hydrogen and the socio-environmental benefit of carbon savings followed by break-even and sensitivity analyses. The identification of the major impact drivers of th Read More

The future is bright for hydrogen as a clean mobile energy source to replace petroleum products. This paper examines new and emerging technologies for hydrogen production storage and conversion and highlights recent commercialization efforts to realize its potential. Also the paper presents selected notable patents issued within the last few years. There is no shortage of inventions and innovations in hydrogen technologies in both academia and industr Read More

The global need for energy has risen sharply recently. A global shift to clean energy is urgently needed to avoid catastrophic climate impacts. Hydrogen (H2) has emerged as a potential alternative energy source with near-net-zero emissions. In the African continent for sustainable access to clean energy and the transition away from fossil fuels this paper presents a new approach through which waste energy can produce green hydrogen from biomass. Bio- Read More

Hydrogen holds an important strategic position in the energy systems of many countries. Many studies have analyzed the acceptance of hydrogen energy technology from the public’s perspective but few have examined it from the corporate perspective. This paper establishes a technology acceptance model and employs structural equation modeling to investigate the factors affecting the acceptance of hydrogen energy technology within enterprises. A Read More

Green hydrogen is a cleaner source to replace fossil-based fuels and is critical in the global shift toward energy production to combat climate change. This review of embedding artificial intelligence (AI) and machine learning (ML) in the value chain of green hydrogen outlines the significant potential for full transformation. These include optimizing the utilization of renewable sources of energy improving electrolysis process hydrogen storage in the sal Read More

This article examines the role of European port authorities in assembling the green hydrogen frontier through the production of speculative connections with prospective hydrogen export zones in the global South. Specifically it analyses the role of a particular discursive tool the pre-feasibility report in fixing the meaning of Namibian territory for the purposes of green hydrogen export disembedding hydrogen products from the social political and ecologica Read More

Global climate change caused by geological processes is one of the main causes of the 5 global mass extinctions in geological history. Human industrialization activities have caused serious damage to the ecosystem the greenhouse effect of atmospheric CO2 has intensified and the living environment is facing threats and challenges. Carbon neutrality is the active action and common goal of mankind in the face of the climate change crisis therefore probi Read More

Coastal areas particularly islands are especially vulnerable to climate change due to their geographic and climate conditions. Reaching decarbonisation targets is a long process which will require radical changes and ‘out of the box’ thinking. In this context islands have become laboratories for the green transition by providing spaces for exploring possibilities and alternatives. Here we explore how hydrogen (H2) energy technologies can be a critical Read More

Green hydrogen could contribute to climate change mitigation but its greenhouse gas footprint varies with electricity source and allocation choices. Using life-cycle assessment we conclude that if electricity comes from additional renewable capacity green hydrogen outperforms fossil-based hydrogen. In the short run alternative uses of renewable electricity likely achieve greater emission reductions.
