South Korea’s largest utility, Korea Electric Power Corporation (KEPCO), has agreed to fund early works for what could become the world’s largest renewable hydrogen hub. The proposed facility, known as the Western Green Energy Hub (WGEH), is set to incorporate up to 50 gigawatts (GW) of wind and solar energy in Western Australia’s southeast corner. Project DetailsThe initial phase of WGEH aims to integrate approximately 6 GW of wind and solar power, targeting an annual production of 330,000 tonnes of green hydrogen. The hub could expand to 50 GW and produce 3.5 million tonnes of green hydrogen each year if…

Hydrogen is a promising renewable energy source, but its susceptibility to leakage and resultant explosions poses significant risks, necessitating comprehensive studies on these hazards. This research provides a detailed review of China’s hydrogen policies, the construction processes of hydrogen refueling stations, and the thermophysical mechanisms of liquid hydrogen leakage, amongst other factors. Hydrogen Policies in China Hydrogen fuel cells have been championed as essential to achieving China’s energy goals. The 2021–2035 Medium- and Long-term Plan for the Development of the Hydrogen Energy Industry underscores hydrogen as a cornerstone in China’s transition towards a low-carbon future. By 2030, China’s annual hydrogen…

The maritime industry is undergoing a major transformation driven by the dual goals of reducing fossil fuel dependence and enhancing air quality. Recently published research in the International Journal of Hydrogen Energy titled “Voyage Scheduling and Energy Management Co-Optimization in Hydrogen-Powered Ships” explores innovative solutions to these challenges. The study illustrates the potential of all-electric ships (AES) to emerge as a sustainable alternative to conventional fossil-fuel-powered vessels. Hybrid Microgrids and Their Advantages AES offers several compelling advantages, including zero emissions, enhanced energy efficiency, and higher sustainability levels. However, the shift to AES introduces new challenges, such as managing a hybrid…

Hydrogen-fueled gas turbines represent a promising technology due to their efficiency and environmental friendliness. However, these turbines operate under extreme conditions, making components prone to corrosion and subsequent hydrogen leakages. Addressing these leakages quickly and accurately is vital to ensure safety. This research introduces a pioneering approach using deep learning to estimate the location and intensity of hydrogen leakages in gas turbines. Challenges in Detecting Hydrogen Leakages Hydrogen leakages present significant challenges due to their explosive and flammable nature. Traditional methods for source term estimation (STE) rely on atmospheric transport and dispersion models, which are computationally intensive and unsuitable for…

Lower Austria’s first hydrogen storage facility was officially opened in St. Pölten. According to Governor Mikl-Leitner, this HydroSolid hydrogen storage facility is considered a significant step in the country’s energy transformation. Udo Landbauer was represented by Christian Hafenecker, Chairman of the Parliamentary Committee for Research, Innovation and Digitization. “Hydrogen is a contemporary issue, and it is urgently necessary to find innovative solutions. This facility can potentially be a global pioneer,” said Hafenecker. It is particularly pleasing that this innovation comes from Lower Austria. Hydrogen as the drive of the future Hydrogen is the most common element in the universe and…

Due to rising CO2 prices, the economic success of energy-intensive companies in Saarland will depend on the shift to hydrogen as an energy carrier. Jürgen Barke (SPD), the Minister of Economics, expressed this belief, announcing that Saarland’s hydrogen strategy will be revised in close collaboration with local businesses. Hydrogen Expansion Must Succeed by 2027 From 2027 onwards, the steel industry in Saarland aims to gradually transition from CO2-intensive steel production using coke to a more climate-friendly approach utilizing hydrogen. The steel industry in Saarland alone will require 120,000 tons of hydrogen annually. The necessary production facilities (electrolyzers) and the planned…

Morocco has unveiled its ambitious “Green Hydrogen Morocco Offer.” This program, projected to attract significant investments over the next decade, could transform the country’s energy and economic landscape. “We are not talking merely about a new industrial sector, but a true economic growth driver for Morocco,” a Ministry of Energy, Mines, and Environment member told Afrik. Although specific figures have not been disclosed, the Moroccan government aims to create thousands of direct and indirect jobs in the sector by the decade’s end. By 2030, the Kingdom plans to supply 4% of the global green hydrogen demand, a rapidly growing market.…
