CUMMINS HyLYZER

HyLYZER is Accelera’s PEM (proton exchange membrane) water electrolysis platform, backed by Cummins Inc. Both models deliver hydrogen at 30 barg without a compressor, and their wide dynamic operating range and fast response suit variable power input from renewable sources. The two differ in installation concept: the HyLYZER 500 is an outdoor containerised system, the HyLYZER 1000 an indoor modular one.

CUMMINS BESS

A Battery Energy Storage System (BESS) stores electrical energy for later use: it takes up surplus energy and releases it when it is needed. It responds rapidly to changes in demand and to grid frequency or voltage instability, supports the integration of renewable sources, and provides backup power and microgrid support – on the grid, at commercial and industrial sites, at community scale and at remote, off-grid locations.

Cummins offers preconfigured BESS units from 211–⁠2280 kWh, with plug-and-play functionality for safe, reliable operation.

  1. Charging the charger system conditions surplus AC grid power or DC solar power for charging.
  2. Storage energy is stored electrochemically in the battery cells as DC potential.
  3. Structure cells form packs, packs form modules, and the modules are aggregated and controlled within a containerised energy storage system.

  1. Conversion power electronics and inverters manage the energy flow; AC/DC conversion and phase-coupled inverters return the stored energy as grid-synchronised AC where required.
  2. Thermal management and protection thermal management regulates the temperature, while safety mechanisms mitigate the risk of overheating, overcharging and system faults.
  3. Discharge the stored energy is released to meet local or grid-scale demand.

Technical background

More information: Cummins – BESS product page

Types of BESS

The Cummins article distinguishes five technologies. This is a general overview, not a description of specific Cummins units.

  • Lithium-based systems: widely used; high energy density, long deep-cycle life and relatively low maintenance.
  • Flow batteries: energy is held in liquid electrolytes in external tanks; scalable and suited to long-duration, large stationary storage.
  • Lead-acid batteries: established, robust and relatively low-cost, but with lower energy density and a shorter cycle life than newer technologies; used in some backup and smaller off-grid systems.
  • Sodium-sulfur batteries: operate at high temperatures; suited to large-scale applications.
  • Supercapacitors (ultracapacitors): very fast charge and discharge, but lower energy density than batteries; suited to frequent cycling and short-duration smoothing.

Safety and system control

Safety mechanisms are designed to mitigate the risks of overheating, overcharging, over-discharge, thermal runaway, and system faults or emergency conditions. Several functions work together:

  • a battery management system (BMS);
  • thermal management and HVAC cooling, regulating the operating temperature;
  • the BESS controller, providing operational safety control;
  • a fire suppression system.

Applications

  • grid stabilisation and peak-demand management
  • backup power during grid outages
  • integration of intermittent renewable sources
  • support for EV charging
  • lower electricity costs
  • reduced emissions
  • Installation types: off-grid and remote · commercial and industrial · community scale.
  • Cummins also integrates battery storage into broader microgrid solutions.
