The Importance of Early Gas Detection in Battery Storage

It’s not an exaggeration to say that the rise of lithium-ion batteries has revolutionised the energy landscape. These compact powerhouses have helped shift our society away from complete fossil fuel dependence, powering the rise of electric vehicles and enabling us to store renewable energy on a previously impossible scale. However, lithium-ion batteries are not an entirely risk-free energy source and can be volatile, which is a cause for concern for battery energy storage systems (BESS) who need to safeguard people – and their assets – from danger.

The Explosive Rise of Batteries

With the rise in lithium-ion batteries, has come a rise in high-profile cases of thermal runaway causing extraordinary damage through explosive fires, causing untold harm to the local environment, as well as eye-watering repair costs. Indeed, the widely-known risks of toxic thermal runaway has caused some pushback against the establishing of BESS sites, making it of paramount importance that battery energy supply can be made demonstrably safer.

Thermal runaway, characterised by uncontrolled heat generation and rapid battery failure, can lead to catastrophic consequences such as fires and explosions. What’s more, as heat can trigger thermal runaway in other batteries, the failure of one can lead to the failure of many, compounding the potential damage cost. While BESS insurers are well aware of such a risk, and have stipulations in place regarding fire, once fire has broken out the damage is already done. Prevention is always better than the cure, and so as suppliers and stakeholders in the lithium-ion battery industry, it’s imperative we address these risks head-on and prioritise safety measures to protect both assets and lives.

The Need for Early Gas Detection

Fortunately, FM Global and UL, two of the world’s largest public safety testing labs, have recognised the importance of gas detection in mitigating the risks associated with lithium-ion battery storage. Their documentation and standards serve as a testament to the critical role that early gas detection plays in ensuring the safety and reliability of energy storage systems. By adhering to these guidelines and implementing comprehensive gas detection strategies, suppliers can bolster their safety protocols and instil confidence in their products.

One of the key indicators of an impending thermal runaway event is the off-gassing from the compounds within the battery. As the internal components degrade or are subjected to extreme conditions, gases such as carbon dioxide, carbon monoxide, and hydrogen may be released, as well as other flammable gases ethylene and propylene. Detecting these gases early is critical, as it provides an opportunity to intervene before the situation escalates further, averting potential disasters. However, ensuring your gas detection system is able to recognise the wide variety of toxic and combustible gases accurately without getting poisoned is crucial. If it’s not accurate, it’s simply not effective and you’re putting your people and property at risk.

Cutting-Edge Gas Detection

While the importance of fire safety and suppression systems in mitigating the risks of lithium-ion battery fires is well-documented, the significance of gas detection systems is often overlooked. Unlike fires, which are often visible and generate smoke, gas emissions can go unnoticed until it’s too late. This gap in awareness underscores the need for robust gas detection solutions to complement existing safety protocols.

Battery Safety: What is Off-Gassing and Why Does it Occur​?

Batteries have become an integral part of our daily lives, powering everything from smartphones to electric vehicles. But have you ever considered the potential risks associated with the batteries that enable the seamless functioning of these devices? While advancements in battery technology have revolutionised the way we live, it’s crucial to explore the potential hazards these power sources pose.

Lithium-ion batteries are combustible and hazardous, with the potential of dangerous and explosive thermal runaway – which can not only have devastating consequences for the environment and property but can threaten human life. Therefore, it is important to understand the first signs of a possible disaster – off-gassing.

Understand Off-gassing: The Silent Emission

Off-gassing refers to the release of gases from lithium-ion batteries often as a result of abuse or misuse. When a battery is subjected to conditions such as overcharging, over-discharging, or physical damage, it can lead to the breakdown of internal components, causing the release of gases. These gases typically include carbon dioxide, carbon monoxide, and other volatile organic compounds – which can be toxic for anyone who may come in contact with them.

Explaining Off-gassing Dynamics:

Off-gassing dynamics differ based on battery setups. In enclosed setups like racks or small housings, off-gassing can accumulate within the confined space, increasing the risk of pressure buildup and ignition. In open setups, such as outdoor installations, off-gassing may dissipate more easily, but still poses risks in poorly ventilated areas.

How Off-gassing Occurs and the Timeline:

Although not always a guaranteed precursor to thermal runaway in lithium-ion batteries, off-gassing events typically occur early in their failure. Thermal runaway occurs when a battery undergoes uncontrolled heating, leading to a rapid increase in temperature and pressure within the cell. This escalation can ultimately result in the battery catching fire or exploding, posing significant safety hazards.

The timeline for off-gassing can vary depending on the severity of the abuse and the type of battery. In some cases, off-gassing may occur gradually over time as the battery undergoes repeated stress, while in other instances, it may occur suddenly due to a single event, such as overcharging.

Factors in which Off-gassing can occur:

  • Physical Damage: Any damage to the battery, such as punctures or crushing, can cause internal components to degrade, leading to off-gassing.
  • Overcharging: Excessive charging can cause the decomposition of electrolytes within the battery, leading to gas generation.
  • Overheating: Like off-gassing, excessive heat can trigger thermal runaway by destabilising the battery’s internal chemistry.
  • Over-discharging: Discharging a battery beyond its recommended limit can also result in the release of gases.
  • Internal Short Circuits: Any malfunction that causes a short circuit within the battery can initiate thermal runaway.
  • Manufacturing Defects: Faulty manufacturing processes can introduce weaknesses in the battery structure, making it more susceptible to thermal runaway.

What are the dangers of Off-gassing buildup?

Off-gassing buildup can lead to the battery storage container turning into a pressure vessel that is just waiting for a spark to ignite. To mitigate this risk, it’s crucial to have a monitored ventilation system in place. Additionally, compliance with FM standards is essential, as BESS should maintain lower than 25% LFL or have a container that can open to vent gas, ensuring safety in case of off-gassing.

Why Early Detection of Off-gassing is Critical:

Early detection plays a critical role in preventing catastrophic battery incidents. By identifying signs of off-gassing at the onset, operators can intervene before the situation escalates into thermal runaway. Here’s why early detection is crucial:

  1. Preventative Maintenance: Early detection allows for timely maintenance and corrective action to address battery issues before they worsen. Routine monitoring of off-gassing can help identify underlying problems in battery systems, such as overcharging or internal damage, enabling proactive maintenance to mitigate risks.
  2. Risk Mitigation: Off-gassing serves as an early warning sign of potential battery failures. By monitoring off-gassing levels, operators can implement risk mitigation measures, such as adjusting charging parameters or isolating malfunctioning batteries, to prevent thermal runaway and its associated hazards.
  3. Enhanced Safety: Timely detection of off-gassing enhances safety for both personnel and property. It provides an opportunity to evacuate affected areas, implement emergency protocols, and minimise the impact of battery-related incidents on surrounding environments. Additionally, early intervention reduces the likelihood of injuries and property damage resulting from thermal runaway events.
  4. Cost Savings: Detecting off-gassing early can help avoid costly repairs or replacements of damaged batteries and equipment. By addressing issues proactively, operators can extend the lifespan of batteries, optimise performance, and avoid unplanned downtime, resulting in significant cost savings over time.
  5. Regulatory Compliance: Many regulatory standards and guidelines mandate the monitoring of off-gassing as part of battery safety protocols. Early detection ensures compliance with regulatory requirements and demonstrates a commitment to maintaining safe battery operations in accordance with industry standards.

Incorporating robust gas detection systems and technologies for early detection of off-gassing is essential for proactive risk management and maintaining the integrity of battery systems. By prioritising early detection, stakeholders can safeguard against potential hazards, minimise disruptions, and promote the safe and sustainable use of battery technology across various applications.

Un futuro a pilas: El auge de las baterías de ión-litio y sus consecuencias para la sostenibilidad

A medida que avanzamos colectivamente hacia un futuro más ecológico en el que el cambio a soluciones energéticas sostenibles se ha convertido en una cuestión sociopolítica mundial de primer orden, las baterías de iones de litio han pasado a ocupar un lugar central como posible solución. Gracias a su capacidad para almacenar grandes cantidades de energía en un formato comparativamente ligero y compacto, han revolucionado todo, desde los wearables de consumo hasta los vehículos eléctricos. Pero ¿hasta qué punto un futuro alimentado por baterías es realmente la solución energética perfecta que hemos estado buscando?

Facilitar oportunidades energéticas más ecológicas

El auge de las baterías de iones de litio conlleva una plétora de ventajas a medida que nos alejamos de la dependencia de los combustibles fósiles, contribuyendo a reducir significativamente las emisiones de gases de efecto invernadero y la contaminación atmosférica. Especialmente en relación con la electrificación del transporte mediante vehículos eléctricos (VE). Al alimentar los VE con electricidad limpia almacenada en baterías, el sector del transporte puede reducir su dependencia de los combustibles fósiles y disminuir las emisiones de gases de efecto invernadero y contaminantes. A medida que el sector de los vehículos eléctricos se hace más competitivo y muchos gobiernos incentivan su uso, los avances en la tecnología de las baterías siguen mejorando la autonomía, la velocidad de carga y la asequibilidad de los vehículos eléctricos, acelerando su adopción y reduciendo aún más la dependencia de los vehículos con motor de combustión interna.

Las baterías de iones de litio también desempeñan un papel cada vez más crucial en la estabilización de las redes eléctricas, al permitir la integración de fuentes de energía renovables intermitentes, como la solar y la eólica, en la red eléctrica. El sol no siempre brilla y no siempre hace viento, pero al almacenar el exceso de energía generada durante los periodos de alta producción y descargarla cuando se necesita, las baterías facilitan un suministro fiable de energía limpia de una forma segura y estable que antes era difícil de conseguir. Al optimizar la gestión de la energía y reducir las pérdidas asociadas a los sistemas energéticos tradicionales, las baterías contribuyen a un uso más eficiente y sostenible de la energía en diversos sectores.

¿Son ecológicas las baterías de iones de litio?

Sin embargo, la creciente prevalencia de las baterías ha venido acompañada de su propio conjunto de implicaciones medioambientales. La extracción y el procesamiento de los metales de tierras raras, como el litio y el cobalto, suelen realizarse en condiciones de explotación en regiones mineras, y el proceso de extracción también puede tener importantes repercusiones medioambientales, como la destrucción de hábitats y la contaminación del agua. Además, la eliminación de las baterías de iones de litio al final de su ciclo de vida también plantea problemas de reciclado y la posibilidad de que se filtren residuos peligrosos al medio ambiente.

Sin embargo, hay otro aspecto preocupante en las baterías de iones de litio que, con su creciente uso, ha provocado un aumento de incidentes peligrosos: su naturaleza volátil y combustible. Cualquiera que haya visto el desbocamiento térmico de las baterías de iones de litio no puede dejar de reconocer el riesgo que conlleva su uso creciente. Incluso el fallo de un dispositivo electrónico de consumo de iones de litio a pequeña escala puede provocar explosiones e incendios mortales y devastadores, lo que hace que el almacenamiento y uso de baterías a mayor escala necesite medidas de seguridad sólidas.

Gestión de riesgos con baterías de iones de litio

Afortunadamente, hay formas de mitigar el riesgo asociado a las baterías de iones de litio. Por lo general, los sistemas de gestión de baterías (BMS) se utilizan para controlar el nivel de carga, la tensión, la corriente y la temperatura de la batería, lo que puede ayudar a identificar problemas en cualquier batería. Sin embargo, hay una forma más eficaz y fiable de detectar el embalamiento térmico: la detección de gases.

Antes de que se produzca el desbordamiento térmico, las baterías sufren un proceso de "desgasificación", en el que se liberan mayores cantidades de COV tóxicos. El control de los gases que rodean las baterías permite detectar signos de tensión o daños antes de que se produzca el desbordamiento térmico.

En la actualidad, muchas aseguradoras se centran en el riesgo de incendio, y animan a los sistemas de almacenamiento de energía en baterías (BESS) a contar con procesos que garanticen que los incendios puedan controlarse y gestionarse de la forma más rápida y eficaz posible. Sin embargo, como las baterías de iones de litio son muy sensibles a la temperatura, una vez que se ha iniciado un incendio en una batería, es probable que las demás baterías cercanas también sufran daños irreversibles o inicien un escape térmico. La solución es sencilla: identificar los problemas lo antes posible mediante la detección de gases y asegurarse de que los incendios no se inicien para evitar catástrofes.

La seguridad no tiene precio

El coste de invertir en una sofisticada detección de gases es insignificante en comparación con el coste de un incendio -aproximadamente el 0,01% del coste de un nuevo proyecto-, lo que lo convierte en una opción obvia para aquellos que buscan mitigar el riesgo en la fabricación, almacenamiento y uso de baterías de iones de litio. Los daños a la propiedad, el coste para la salud humana (e incluso la vida), junto con el daño causado al entorno natural con posibles problemas de contaminación tras el fallo de la batería, son amplios y significativos. Combinado con la amenaza que supone para el mantenimiento de un negocio, además del control de daños necesario, la necesidad de evitar operaciones de limpieza complicadas y costosas es primordial. Esto es algo que el equipo de Crowcon comprende mejor que nadie.
