Technology

Lakeside offers Emerson technologies, such as DeltaV Distributed Control System, measurement devices, valves, and gas analysis instruments as well as 3rd party technology to ensure advanced automation and process optimization for the electrolysis system.

Precise, stable flow control is critical across electrolyzer Balance of Plant systems to protect the stack and maintain efficient hydrogen production. Poor control valve performance can introduce oscillations, off-spec conditions, and temperature/pressure upsets—driving higher operating cost and increasing safety risk in a hydrogen environment. At the same time, many sites need valves that can be upgraded over time (actuator/trim changes), reduce ongoing maintenance burden, and support low-emissions packing compliance to meet environmental requirements.

Fisher GX, easy-e, and HP control valves are proven solutions for accurate throttling in demanding BoP services, delivering high rangeability for tight control over wide operating conditions. With broad pressure class and temperature coverage, optional noise attenuation, and a wide selection of actuation options (pneumatic, electric, hydraulic), these valves can be configured to match control, reliability, and safety objectives on electrolyzer skids. Their maintainable design and long service life help extend maintenance intervals and reduce lifecycle cost, while ISO 15848-compliant packing options support fugitive emissions targets. The result is tighter, more accurate control (supporting consistent operation), improved operator safety, fewer interventions, and a measurable reduction in operational costs.

Accurate demineralized water flow measurement is essential for electrolyzer Balance of Plant systems. Low or uncertain flow can drive temperature increases in the stack, raising the risk of ignition in a flammable hydrogen environment. Many installations also require redundant, SIL-2 rated measurement—one signal for control and a separate, independent signal for safety shutdown—plus proof of FMEDA data and SIL certification, all within tight space constraints.

The Rosemount 8800 Dual Vortex Flowmeter addresses these needs by providing two independent flow measurements in one meter body for SIL-2 applications. Its all-welded, impulse-line-free design minimizes leak points and simplifies installation, while the isolated sensor can be replaced online to reduce downtime. Full FMEDA documentation and SIL certification support faster safety compliance and safer, more reliable electrolyzer operation.

Pressure measurement is a core requirement across electrolyzer Balance of Plant systems, but projects often get complicated when multiple transmitter models are needed to cover different ranges and applications. In hydrogen service, especially at higher pressures, hydrogen permeation can also be a concern, and selecting the right sensor often depends on knowing the exact pressure span up front. These factors can increase engineering effort, slow procurement, and add installation time and cost.

The Rosemount 3051 (3051S Wireless) Pressure Transmitter helps simplify pressure instrumentation by using a single, wide-range model to cover broad pressure needs while reducing installed cost and schedule risk. Wireless installation can significantly cut field labor and materials versus wired runs, and standardizing on one platform streamlines maintenance and spares. For hydrogen applications, gold‑plated diaphragms help mitigate permeation concerns, supporting reliable long-term performance. The result is reduced project complexity, faster deployment, and lower installed cost, while maintaining dependable pressure measurement in hydrogen production environments.

Accurate temperature insight is critical across electrolyzer Balance of Plant equipment, especially around heat exchangers and thermal loops, but traditional approaches create tradeoffs. Surface temperature readings often lack accuracy and repeatability, while thermowell-based measurements are more precise yet add design and installation complexity and introduce additional process leak paths.

Rosemount X‑well™ Technology, used with the Rosemount 3144P or 648 Temperature Transmitter and the 0085 Non‑Intrusive Temperature Assembly, delivers a reliable alternative by enabling temperature measurement without penetrating the pipe. This makes it easy to add additional temperature points around heat exchangers to monitor fouling, degradation, and heat duty, while reducing project burden. The result is lower temperature measurement cost (up to 29%), faster execution with ~65% less engineering design time and ~70% less installation time, and improved operational visibility without increasing leak risk.

Level control in hydrogen/oxygen separators is a key safety function in electrolyzer Balance of Plant systems. Unreliable measurement can lead to overfill and increase the risk of gas carry‑under into the water system, driving upsets, maintenance, and safety exposure.

The Rosemount 5300 Guided Wave Radar delivers dependable separator level measurement in challenging conditions, including very low dielectric fluids. Dynamic vapor compensation helps maintain accuracy as vapor conditions change, and Direct Switch Technology improves tolerance to coating, foam, turbulence, and vapor. IEC 61508-certified options support SIL 2 (single device) and SIL 3 (with redundancy), helping improve safety, reduce maintenance cost, and minimize overfill risk for higher throughput.

Reliable gas analysis is critical for electrolyzer Balance of Plant safety, helping detect membrane integrity issues and prevent excursions toward flammability limits. Operators also need dependable measurement of trace O₂ in H₂ and trace H₂ in O₂, even with water vapor present, without the downtime and cost of consumable sensors.

The Rosemount X‑STREAM™ Enhanced Gas Analyzer System measures trace O₂ in H₂ and trace H₂ in O₂ in one analyzer, using an integrated sample gas cooler to remove water and protect measurement accuracy. TCD (H₂) and PMD (O₂) modules avoid consumables, while auto‑calibration/validation and Modbus TCP/IP + web access simplify ongoing verification and remote diagnostics. The result is safer operation, lower maintenance, and faster detection of hydrogen/oxygen crossover and leaks.

High‑purity demineralized water is essential to protect electrolyzer stacks and maintain stable hydrogen production. If water quality degrades, conductivity can rise quickly, increasing the risk of contamination, reduced performance, and potential stack damage. Because electrolyzer feedwater often needs to be controlled to very low conductivity (≈0.05 µS/cm or lower), operators need a measurement that is accurate and responsive in ultra‑pure water, so problems are identified early and corrected before they impact operations.

The Rosemount 400 Conductivity Sensor is designed for high‑purity water conductivity measurement in electrolyzer Balance of Plant systems. Its 0.01 cell constant provides reliable accuracy in ultra‑low ranges down to 0.01 µS/cm, enabling early detection of water quality drift. By deploying Rosemount 400, teams gain faster indication of water treatment issues, improved reliability of the demin water system, and stronger protection against electrolyzer stack damage.

Electrolyzer Balance of Plant systems demand stable, repeatable control to avoid variability that drives inefficiency, alarms, and upsets. When operators are forced into constant manual adjustments, and the process can’t anticipate disturbances, performance drifts and troubleshooting time climbs.

DeltaV DCS with the PK Controller, paired with DeltaV PredictPro Advanced Process Control, reduces variability using model-based control so operations can run closer to constraint limits with more consistency. PredictPro also accelerates deployment through automated model development, and offline MPC simulation helps test strategies and train operators before commissioning, improving product quality, reducing time spent tuning, and lowering operating cost.
