As electrical energy grids decarbonise through increased renewable generation the intermittency and lack of inertia of renewables leads to an increased reliance on grid-scale energy storage technologies.

In this workshop, we introduce the current landscape of energy storage technologies, showing the current dependence on Li-ion battery systems and the potential for increased use of other chemistries and archetypes, for example flow batteries. Following this we discuss the issues and challenges of these two technologies, focusing on the widely adopted Li-ion battery. The hazards of Li-ion batteries, particularly those related to thermal runaway, are presented from a cell to systems level. Past Li-ion BESS incidents are discussed in relation to these hazards to understand the most common root causes.  Given an overview of current codes and standards for BESS at different levels in the built environment a holistic approach adopting process safety and systems thinking is applied to address gaps in BESS hazards regulatory framework. This holistic approach is then applied to flow batteries to discuss any needs for regulatory differences.

From this workshop, the audience will leave with a greater understating of Li-ion BESSs and their hazards, and be actively involved in addressing gaps in BESS safety standards.

Managing Chloride Stress Corrosion Cracking in LNG Fractionation Columns
Birinengi Harry, Nigeria LNG Ltd, Nigeria

This presentation discusses the risk-based approach used over two decades to manage chloride stress corrosion cracking (Cl-SCC) in LNG de-ethaniser columns, the discovery of extensive Cl-SCC, and the mitigation strategies, including composite wraps, implemented to prevent catastrophic failures and maintain process safety. Detailed assessments and repair methodologies for affected columns will also be covered, highlighting the successful return to service while awaiting replacement.

There has been increasing interest the major hazards sector in recent years in what makes an effective relationship between a regulator and dutyholder. This interest stems from events such as the Fukushima Daiichi nuclear accident, the Grenfell fire and the Deepwater Horizon oil spill. These events highlighted how factors such as blurred accountabilities, insufficient independent challenge and lack of agility in the regulatory regime can contribute to disaster.

Recent work by organisations such as the Nuclear Energy Agency and the International Network for Delivery of Regulation, has attempted to bring clarity to effective regulator-dutyholder interactions, and how each can deliver their distinct roles while enabling safe and environmentally-responsible operations.

This workshop, hosted by the Hazards Forum, will explore the factors which underpin effective relationships between regulator and dutyholder, including how such relationships facilitate open and honest dialogue, while recognising the common goal of safety and environmental improvement. Further it will explore how the relationships might evolve to address the increasing complexity of technologies, processes and organisations and ensure resilience against unforeseen events.

The workshop will feature contributions from the UK Office for Nuclear Regulation and other key stakeholders. Delegates will have an opportunity to:

• Reflect on the health of their own relationships with regulators / dutyholders
• Share good practice and learning with peers across different sectors
• Learn about the latest developments in this field
• Explore how regulators and dutyholders can adapt to the challenges of new technologies and organisational models
