At this year’s Gastech Conference and Exhibition, Dr Karina Almeida Leñero and Pablo Giacopinelli will present a study of several explosion scenarios in a hydrogen storage facility, conducted using the CFD consequence modelling tool, FLACS-CFD.

Due to its unique flammability characteristics, the use of LH2 in aviation presents several safety challenges, from the materials used through aircraft refuelling procedures to the storage of large amounts of LH2 at or near the airport.

At the International Hydrogen in Aviation Conference, Gexcon will discuss how to use advanced modelling tools to understand LH2 hazards in the aviation industry….

Blending hydrogen into the natural gas grid will support the de-carbonising effort in the energy system.

However, the safe use of hydrogen as a fuel presents different challenges than conventional hydrocarbon-based fuels.

At the 2022 International Loss Prevention Symposium, Gexcon will present the result of CFD-based explosion analysis of hydrogen-methane-air mixtures which was performed using FLACS-CFD consequence modelling software.

The resulting fireball phenomenon from a potential hydrogen release is still being modelled using traditional and potentially misleading methods.

During the 17th EFCE International Symposium on Loss Prevention and Safety Promotion in Process Industries, Gexcon’s Senior Research Scientist Hans Boot will present a paper entitled “Why a Hydrogen fireball should not be modelled as a BLEVE event”.

During the 2022 Spring Meeting and 18th Global Congress on Process Safety, Gexcon US CEO & Principal Engineer Scott G. Davis, PhD, P.E., CFEI will present a paper entitled “Improving Our Understanding of Hydrogen through Testing and Advanced Modeling to Avoid Possible Pitfalls and Ensure Its Safe Use”.

We can ensure the safe production, transportation, and usage of hydrogen by carefully considering its typical properties and associated safety aspects.

In an earlier blog, we talked about some energy carriers playing the main role in the energy transition, hydrogen, and ammonia. Strongly linked to that is also CO2, which possibly is not so obvious.

Today, two of the new energy carriers are hydrogen and ammonia. When used at a large scale during the energy transition process, the safe handling of these energy carriers plays a major role.

Using our flagship CFD modelling tool FLACS-CFD, Gexcon conducted several case studies on real facilities looking at the design of bulk storage areas in terms of safety during an ignited event, using relevant standards and documentation for guidance.

Despite being environmentally friendly, hydrogen has a reputation for being dangerous, with fire and explosion hazards as the primary concern. Are hydrogen hazards too dangerous to handle?

In this interview, Keith explains his perspectives on issues related to standards for hydrogen industry based on his experience within HyTechnical Program in the UK.

In this interview, Lee shares his insights on the knowledge gaps in hydrogen safety that need to be addressed to fully utilize hydrogen as an energy vector.

In this interview, Linda Febvre, the Hydrogen HSE Manager at Engie, explains her view on challenges that the industry is facing in developing a reliable hydrogen production and storage system.

In this article, Dr. Kees van Wiingerden explains his thoughts on the safety aspect of hydrogen as a fuel.

The key technical challenge is the development of a safe hydrogen system. Even though hydrogen is considered safer for the environment, its flammability, buoyancy, ability to embrittle metals, and other properties that require engineering control make designing a safe hydrogen system a challenging process.
