Oilfield Scenario Application Case—Fourth Oil Production Plant

2025-12-18


North China Oilfield 30kW/100kWh Demonstration Energy Storage Project

  • A 30-kW/100-kWh integrated photovoltaic-storage near-zero-carbon energy storage demonstration facility has been established at Well Jing25-6 in the North China Oilfield.
  • It has withstood the cold temperatures of nearly -20℃ in the Hebei region and is operating normally.
  • Even in winter, as long as the weather is clear, fully carbon-neutral operation is entirely achievable.
  • In rainy weather, switching to peak-valley mode allows the stored valley-time electricity to meet the power demands for the entire day.
  • The cloud platform enables 24-hour, uninterrupted monitoring across the entire country.
  • Sodium-ion batteries exhibit excellent cycling stability, with a state-of-health remaining close to 100% to date.
