Gas pipelines are the lifelines of Europe's energy system. Stretching across hundreds of thousands of kilometres, these networks carry explosive gases at high pressure, monitored and regulated by control stations, compressors, valves, and safety systems. Every component in this chain depends on uninterruptible power supply (UPS) systems to ensure that safety equipment, emergency lighting, fire and gas detection, communication systems, and critical control systems continue to function under all circumstances-including grid outages or external shocks.

Until now, the industry has relied heavily on lead-acid and nickel-cadmium batteries to ensure back-up power for these UPS installations. However, both chemistries have major drawbacks: lead acid suffers from limited lifespan, hydrogen gas emissions, frequent maintenance, and sudden failure risk; nickel-cadmium is costly, environmentally hazardous, and requires dedicated cooling and housing. Lithium-ion battery systems have been banned from these EX Zones, and ATEX-classified explosive environments.

Against this backdrop, Altech has launched its design for a drop-in, explosion-proof sodium nickel chloride battery system that represents not just an incremental improvement, but a transformative solution for the European heavy Industry sector.

A UPS BATTERY BUILT FOR EXPLOSIVE ENVIRONMENTS

The new Altech-AMPower UPS battery has been designed from the ground up with explosive environments in mind. The core sodium nickel chloride chemistry is inherently safe, eliminating the risks that plague alternative chemistries. Unlike lithium-ion, it contains no flammable liquid electrolytes. Unlike nickelcadmium and lead acid, it does not emit hydrogen or toxic vapours during operation.
Each unit is a sealed, pressure-tight system. It requires no cooling systems, and no ventilation. This is a major advantage in ATEX and Ex-zones-areas where explosive gases or combustible dusts may be present. Conventional batteries often require specialised housings, air conditioning, or hydrogen venting infrastructure, all of which add to capital and operating costs. With Altech's system, operators eliminate these additional requirements, simplifying certification and dramatically reducing both capex and opex.

The batteries also withstand extreme operating conditions. With a working range from -20 degC to +60 degC, they remain reliable in the Arctic cold, desert heat, or confined compressor stations that often lack climate control. Extensive third-party tests have demonstrated SNC resilience under severe stress scenarios: 30- minute gasoline fires at 850 degC, saltwater immersion, bullet penetration, rod impact, and overcharge events.

In each case, the battery did not explode, ignite, or release hazardous contents.

This robustness is why sodium nickel chloride has been used for years in telecoms harsh environments where temperature is very hard to manage, to secure the 48VDC back-up-but Altech's new 384 V / 15 kWh UPS system marks the first time this technology has been optimised for large-scale European pipeline infrastructure.

TECHNICAL OVERVIEW OF THE UPS SYSTEM

The system consists of three 136 V SNC modules connected in series, producing a combined nominal voltage of 384 VDC. Each module uses advanced Zebra cell architecture, incorporating 53 ceramic electrolyte cells in series, with each cell delivering a stable nominal voltage of 2.56 V.

Key technical highlights include:

- Nominal Voltage: 384 V, perfectly aligned with standard pipeline UPS requirements across Europe.

- Capacity: 15 kWh, sufficient for long-duration redundancy and full back-up of critical systems.

- Battery Chemistry: Sodium nickel chloride (SNC) solid-state ceramic cell; non-flammable, explosion-proof, hydrogen-free.

- Cycle Life: More than 5,000 cycles with service life exceeding 15 years, minimising replacement cycles.

- Maintenance: Fully sealed, maintenance-free; no impedance checks, or charge cycling needed.

- Operating Temperature Range: -20 degC to +60 degC, with passive cooling (no HVAC required).

- Enclosure: Industrial Stainless-steel cabinet.

- BMS: A master-slave battery management system monitors state of charge, state of health, percell voltages, and temperatures. Communication protocols include RS485, CAN Bus, and Modbus, ensuring seamless integration with existing SCADA systems.

- Certification: CE, UN38.3, IEC 62619, RoHS; further certifications such as ABS and DNV for marine and offshore applications are in progress.

The cabinet is designed for drop-in replacement. Existing UPS cabinets and inverter systems remain unchanged; operators simply remove their ageing lead-acid banks and install the SNC units. This dramatically reduces downtime and eliminates the high capital costs associated with full UPS cabinet replacement.

THE DROP-AND-PLAY ADVANTAGE

In the world of pipeline infrastructure, downtime is not an option. Every hour of system interruption can cost millions in lost throughput while increasing operational and safety risks. Traditionally, replacing ageing leadacid batteries with next-generation sodium-nickel-chloride (SNC) systems has required costly and complex reconfiguration of the battery management system (BMS) due to voltage mismatches.

Altech's innovative 384 V DC battery architecture eliminates this problem. By designing the SNC packs to operate at the same voltage range used by global UPS manufacturers, Altech ensures complete compatibility with existing BMS configurations. This means operators can directly replace legacy leadacid batteries with Altech's higher-performance SNC units-without rewiring, reprogramming, or system redesign.

The result is a genuine drop-and-play solution: seamless installation, zero modification to critical control systems, and immediate performance improvement. For operators of gas pipeline and other mission-critical infrastructure, this compatibility translates into faster deployment, reduced engineering downtime, and a safer, more reliable power backup system.

MARKET OPPORTUNITY AND GROWTH POTENTIAL

Europe's gas pipeline network is vast and aging. Control stations, valve nodes, and compressor plants all rely on UPS banks installed 10-20 years ago. Most of these systems use lead-acid batteries, now failing or requiring costly maintenance. Analysts forecast tens of thousands of battery replacements across Europe in the next decade.

Altech's solution directly aligns with operator needs:

- Regulatory compliance. EU directives increasingly discourage hazardous chemistries, pushing operators away from cadmium and lead.

- Sustainability. SNC is salt-based, cobalt-free, and far less hazardous to recycle.

- Cost efficiency. Longer lifespan means fewer replacements; total cost of ownership is significantly lower than NiCd or lead acid.

- Safety in ATEX zones. Fireproof, explosion-proof chemistry provides peace of mind in explosive environments.

- Scalability. Modular BMS architecture allows adaptation for telecoms, data centres, transport hubs, and manufacturing facilities.

ROLE OF ALTECH AND AMPOWER

The system has been developed under the technical leadership of Arnoud Blijleven, Altech's Chief UPS Back-up Systems Engineer, who brings two decades of experience in European critical power systems.

Mr. Blijleven defined the technical specifications, and will oversee extreme-condition testing, to ensure CE/IEC compliance whilst maintaining alignment with customer needs.

For AMPower, the project represents a natural extension of its production expertise. As the world's largest producer of sodium nickel chloride batteries (originating from the GE Durathon(R) program), AMPower operates at 100 MWh per annum capacity, scalable to 200 MWh. The move into 15 kWh / 384 V systems broadens its market reach and drives greater cell output efficiencies Together, Altech and AMPower form a powerful partnership: Altech brings European market access, customer relationships, and engineering expertise, while AMPower provides scalable manufacturing and proven SNC cell technology.

COMPARISON WITH ALTERNATIVE BATTERY CHEMISTRIES

The European pipeline industry has long relied on batteries that now face increasing scrutiny. Altech's SNC solution solves many of the long-standing problems.

- Lithium-ion: High energy density but unsuitable for ATEX zones. Thermal runaway leads to sparks, flames, and gas venting. Banned in explosive atmospheres. Insurance costs prohibitively high.

- Nickel-cadmium: Long float life but toxic cadmium, hydrogen emission, large footprint, and high upfront cost. Requires regular maintenance and dedicated cooling/housing.

- Lead acid: Low cost but short life, high failure risk, large housing requirement, hydrogen emission, and constant checks.

- Sodium nickel chloride: Fireproof, explosion-proof, sealed, maintenance-free, long life (15-20 years), wide temperature range, inherently safe, and suitable for ATEX zones.

A side-by-side comparison shows SNC outperforms in almost every category of relevance to explosive infrastructure-from safety and environmental compliance to lifecycle cost and reliability.

Altech Batteries' new 384 V / 15 kWh sodium nickel chloride UPS battery is more than a new product-it is a paradigm shift for pipeline safety and energy security. By directly addressing the unique challenges of explosive ATEX environments, the Company is targeting itself as the preferred solution provider for Europe's critical infrastructure operators.

As Europe accelerates its energy transition, safety and resilience in its existing infrastructure remain paramount. Altech's SNC UPS battery delivers precisely what the market demands: a fireproof, explosionproof, drop-in solution with unmatched longevity and reliability.

Altech Managing Director Iggy Tan stated:

"This launch represents a pivotal moment for Altech as we deliver a safe and practical energy solution into one of Europe's most sensitive sectors. Gas pipeline infrastructure demands absolute reliability and explosion-proof technology. Our new 384 V / 15 kWh UPS battery not only meets these demands-it exceeds them, offering operators a true drop-in replacement for lead-acid and nickel-cadmium systems.

We are proud to partner with AMPower on this breakthrough, and with the first order already secured, we anticipate strong and rapid adoption across Europe".
