About MCEE Solutions
MCEE Solutions GmbH was founded in Berlin to bring a decade of hard-won fire safety expertise to one of the most urgent challenges in the global energy transition: preventing thermal runaway from cascading through large-scale battery energy storage systems.
The story behind it starts earlier.
In 2009, a core German fire protection technology was introduced to China by the same team that stands behind MCEE today. What followed was more than a decade of development shaped by China's rapid industrial expansion, an environment defined by the scale and complexity of its fire hazards, and by the practical experience of tackling them without the safety infrastructure that more established markets had built up over decades. That combination of technical rigour and real-world pressure produced something a laboratory alone could not: a fire suppression approach tested and refined through live fire events, not just controlled experiments.
The most significant period of that collaboration lasted over ten years. The result is the LBF system, a Thermal Runaway Propagation Protection (TRPP) system designed specifically for containerised lithium-ion BESS at utility scale.
Why we restructured
We made a deliberate decision to change our internal structure. The global renewable energy industry is facing a fire safety challenge that existing frameworks were not designed for. Battery systems are scaling faster than the protection concepts deployed inside them. The fire safety conversation needs to happen at an international level, with insurers, regulators, standards bodies, and asset owners, and it needs to be backed by evidence generated at the scale where the risk actually exists.
MCEE Solutions GmbH is the vehicle for that engagement. It is the European commercial entity, responsible for business development, institutional partnerships, and standards work. The technical development and all large-scale live fire testing continue to be conducted by our partner team at MCEE lab in SanMing City, Fujian Province, China, where the LBF system was built and where the expertise lives.
What we have validated
In September 2025, we conducted container-level thermal runaway propagation testing at our Sanming facility, witnessed and documented by DEKRA Testing and Certification.
The configuration: a 5 MWh containerised BESS using 530Ah LFP cells. Thermal runaway induced by full module overcharge — 104 cells simultaneously, worst-case initiation conditions.
The outcome: no propagation to adjacent modules. No open flames. All non-initiating modules electrically intact after the event.
The full DEKRA Witness Test Report is available on request to qualified enquiries.
Where we focus
Containerised battery energy storage — utility-scale, large-format LFP, the configurations now being deployed globally at 3-5 MWh per container and beyond. NFPA 855 (2026) has introduced Thermal Runaway Propagation Protection as a named safety category for the first time. The test methods that define how effectiveness should be measured are still being developed. We are actively engaged in that process.
This is a specific problem. We have spent more than a decade on it.
