Can Green Hydrogen Production Be Economically Viable under Current Market Conditions
Dec 2020
Publication
This paper discusses the potential of green hydrogen production in a case study of a Slovenian hydro power plant. To assess the feasibility and eligibility of hydrogen production at the power plant we present an overview of current hydrogen prices and the costs of the power-to-gas system for green hydrogen production. After defining the production cost for hydrogen at the case study hydro power plant we elaborate on the profitability of hydrogen prod Read More
Utilization of Excess Water Accumulation for Green Hydrogen Production in a Run-ofTiver Hydropower Plant
Jun 2022
Publication
This paper discusses the potential for green-hydrogen production in a run-of-river 9 hydropower plant. This particular hydropower plant has no significant water accumulation but 10 there is the potential for limited hydrogen production due to a mismatch between the daily 11 predefined electricity production (known as the timetable) and the actual water inflows. The 12 timetable for the hydropower plant is prepared by the operator of the electro-energ Read More
Comparative Analysis of Direct Operating Costs: Conventional vs. Hydrogen Fuel Cell 19-Seat Aircraft
Jul 2023
Publication
In this paper a comparative analysis of direct operating costs between a 19-seat conventional and hydrogen-powered fuel cell aircraft is performed by developing a model to estimate direct operating costs and considering the evolution of costs over time from 2030 to 2050. However due to the technology being in its early stages of development and implementation there are still considerable uncertainties surrounding the direct operating costs of hy Read More
An Overview of Low-carbon Hydrogen Production via Water Splitting Driven by Piezoelectric and Pyroelectric Catalysis
Jun 2024
Publication
The focus on sustainable energy sources is intensifying as they present a viable alternative to conventional fossil fuels. The emergence of clean and renewable hydrogen fuel marks a significant technological shift toward decarbonizing the environment. Harnessing mechanical and thermal energy through piezoelectric and pyroelectric catalysis has emerged as an effective strategy for producing hydrogen and contributing to reducing dependence on Read More
Sizing of a Hydrogen System for Green-hydrogen Production by Utilising Surplus Water Accumulation in a Hydropower Plant
Jun 2025
Publication
The utilisation of surplus hydro energy can enhance the profitability of hydropower plant operation by cogeneration of green hydrogen along regular electricity production. Effective integration of the hydrogen system requires its appropriate sizing based on surplus hydro energy availability its temporal dynamics scheduled electricity generation and expected hydrogen demand. The article introduces a decision-support tool designed for the optima Read More
