With respect to hybrid renewable-energy-resources (HREP) hydrogen stations, WP1 is developing a framework to identify typical and atypical accident scenarios related to hydrogen systems that may lead to uncontrolled releases of hydrogen, especially considering those that directly endanger nearby communities and the neighbouring environment.
Tasks (Ts) of WP1 include:
Identification of key parameters and safety requirements of HREP hydrogen stations is a crucial step towards proposing appropriate new procedures for preventing accidents and ensuring process safety. Bringing skilled people together, enabling safe operational control and promoting organisation commitment towards safety are critical pillars for minimising accident risk. Lessons from accidents and identification of best safety practices, regulations and rules in different countries can help to identify key performance indicators in a standardised way, allowing for comparison and improvement. Thus, safety culture models from other high-risk industries are considered in this WP2.
Tasks of WP2 include:
In the case of HREP hydrogen stations, designed protection and emergency response systems typically fall within one of the following categories. Detectors and alarms for slight hydrogen leaks, automatic shutdown systems to close the hydrogen valve quickly, emergency exhaust systems, inert gas nitrogen introduction systems, cooling systems, fire-extinguishing systems (e.g., water spraying) and anti-explosion walls. Based on the scenarios identified in WP1, a probabilistic digital twin at the system level is being developed in WP3 to analyse the effectiveness and performance of abovementioned systems under the uncertainties involved in various scenarios.
Tasks of WP3 include:
Public acceptance of hydrogen stations is analysed considering knowledge of hydrogen technology, risk perception, benefits, environmental consciousness, travel behaviour, and social interaction. In WP4, an online questionnaire survey is carried out with residents who live near and also far from hydrogen stations. Additionally, effects of differences in available accident risk information are investigated for effective risk communication procedures.
Tasks of WP4 include:
Hydrogen should be produced commercially under competitive conditions, and a potential HREP station should be evaluated against relevant codes and standards. The problem arising from the variability of renewable energy sources can be solved by combining two or more sources with batteries. In WP5, various parameters of HREP hydrogen stations are examined using artificial intelligence techniques, while the whole system can be evaluated economically considering different probabilistic scenarios for the hydrogen load demand, as well as issues of unreliability stemming from the renewable energies.
