The landscape of the energy
industry is being redefined by a new standard.
Recently, GB/T 46261-2025 "General Technical Requirements for Fire Monitoring and Early Warning
Systems of Electrochemical Energy Storage Power Stations" was officially released. This
milestone national standard not only puts a "safety hoop" on the rapidly developing
electrochemical energy storage industry, but also releases a key signal about future energy
safety between the lines.
New National
Standard Draws "Safety Red Line", Hydrogen (H2) Monitoring Becomes a "Compulsory
Question"
Reading the new standard carefully, one of its core highlights is drawing an extremely
specific and quantifiable "safety red line" for key gas monitoring in energy storage power
stations.
In clauses 5.4.2.3 and 5.4.2.4, the standard gives clear ranges for
the low and high alarm settings of three key gases - hydrogen (H2), carbon monoxide
(CO), and carbon dioxide (CO2) - for air-cooled and
liquid-cooled monitoring and alarm devices respectively.
It is worth noting that whether it is an air-cooled or liquid-cooled system, hydrogen
(H2) is listed as one of the core indicators that must be monitored, and strict
alarm thresholds are set. For example, in liquid-cooled devices, the low alarm setting value for
hydrogen is set at 200×10⁻⁶ (i.e. 200ppm), and the high limit is in the range of
500×10⁻⁶ to 1000×10⁻⁶.
What does this mean? This means that
hydrogen, as one of the iconic products of the early stage of thermal runaway of lithium
batteries, its precise and sensitive monitoring capability is no longer an "optional question"
for the industry, but a "compulsory question" certified by national standards to ensure energy
storage safety.
The new national standard pushes hydrogen monitoring to the center stage of energy storage
safety with unquestionable authority. However, when we look away from the energy storage cabin,
a grander picture leaps before our eyes: hydrogen monitoring in energy storage safety is just
the tip of the iceberg of the "hydrogen safety" challenge in the future energy system. From
green electricity hydrogen production, high-pressure storage and transportation, to fuel cells,
industrial applications... a huge hydrogen economy is rising, and the lifeline running through
it is exactly ubiquitous hydrogen safety.
A question arises spontaneously: Who can provide an all-round, full-scenario, and
full-coverage safety "base" for this huge hydrogen energy industry chain?
Metachip's Answer:
The "Big Hydrogen Strategy" Beyond This
Facing this proposition of the times, we at Metachip have already made
forward-looking layouts.
We know deeply that isolated products cannot cope with systemic challenges. Therefore, we have
built a comprehensive and in-depth "Big Hydrogen Strategy", committed to becoming an all-round
"solver" in the field of hydrogen sensing, providing a one-stop answer for all customers' needs
in hydrogen safety.
The "Big Hydrogen" strategy will provide services for customers in a three-dimensional and
multi-dimensional way:
1. [Cornerstone
Layer: Multi-principle Sensor Matrix]
We firmly believe that all precise monitoring comes from underlying core technology. Refusing
"single point dependence", we have developed hydrogen sensors based on various principles such
as catalytic combustion, semiconductor, electrochemical, field effect, thermal
conductivity, and alloy film for different industry application scenarios. This
means:
-
Full Coverage: Whether customers need ppb-level trace detection or 100%
VOL-level hydrogen purity analysis, we have corresponding sensing "sharp tools".
-
Optimal Solution for Scenarios: Targeting different working conditions
(high temperature, high humidity, interfering gases), we can provide the most adaptable
and reliable sensor cores.
2. [Application
Layer: Instrument Product Line Covering All Scenarios]
Based on powerful hydrogen sensing technology, we have created hydrogen detection modules and
instruments covering different sub-scenarios:
-
Leakage Monitoring: From ppm-level trace hydrogen
detectors, wearable/fixed hydrogen alarms, to
vehicle-mounted hydrogen detection modules and hydrogen in oil
detection modules, building a leakage protection net with no blind spots
from individuals to the environment.
-
Process Analysis: With hydrogen purity analyzers
(online/portable) as the core, ensuring process safety and product quality in key links
such as hydrogen production and hydrogen use.
3. [Solution Layer:
Multi-dimensional Smart Solutions]
We provide not only products, but also smart safety systems deeply integrated with scenarios:
-
Hydrogen Production and Power Generation Scenarios: Provide
high-precision hydrogen online analysis systems for hydrogen production
stations and hydrogen-cooled generators.
-
Storage, Transportation and Utilization Scenarios: Create all-weather,
high-sensitivity hydrogen leakage monitoring and early warning systems.
-
Laboratory Scenarios: Build multi-dimensional and three-dimensional
laboratory gas leakage monitoring systems.
-
Inspection and Investigation Scenarios: Provide high-precision
trace leakage detection solutions to make hidden dangers nowhere to
hide.
The introduction of the GB/T 46261-2025 standard has drawn a safety baseline
for the industry.
For Metachip, this is not only an "action guide" that must be responded to accurately, but also
a "charge horn" for the "Big Hydrogen Strategy" to fully empower the industry.
From a small sensing chip to a smart linked safety system, we are not only followers of
standards, but also practitioners promoting the industry safety level to constantly exceed
standards.
The new national standard points out the direction for energy storage safety, and Metachip is
committed to building the most solid and reliable "safety base" for the voyage of the entire
hydrogen era!
