Energy Recuperation Solutions

Capturing Lost Energy in Motion

Overview

In heavy industrial operations, massive amounts of kinetic energy are wasted as heat during braking or descending phases. STC’s Dry-Electrode AHSC Supercapacitor systems are designed to capture this "lost" energy and redeploy it during the next power cycle. Whether it’s an elevator in a skyscraper or a pumping unit in an oil field, our recuperation technology turns waste into efficiency, significantly reducing energy consumption and operational costs.

Core Applications

Smart Elevator Systems

High-rise elevators generate significant regenerative energy during braking or when traveling down with a heavy load. STC systems capture this power and feed it back for the next ascent, reducing building energy costs by up to 20%–30%.

Oilfield Pumpjack Machine

Pumping units experience cyclic load fluctuations. Our energy recuperation modules store energy during the downstroke and release it to assist the motor during the upstroke, smoothing the power demand and protecting the local grid from surges.

Industrial Cranes & Hoists

In ports and construction sites, lowering heavy containers provides a prime opportunity for energy recovery. STC’s high-power modules handle the massive current bursts generated during rapid descent, storing it for the next heavy lift.

Typical Project Scenario

Energy Recuperation for Pumpjack Machine

The Challenge: Managing Cyclic Energy Waste

Pumpjack machine, the workhorses of oil extraction, rely on motors to drive counterweights through upstroke and downstroke cycles. Due to fluctuating downhole loads, mechanical balance is often imperfect, causing the motor to frequently enter a regenerative braking state (acting as a generator). In traditional systems, this surge of energy is often wasted as heat, leading to high operational costs, energy inefficiency, and increased strain on the local power grid.

The STC Solution: Intelligent Energy Recuperation

STC’s Energy Recuperation System is specifically engineered to bridge this efficiency gap. Our system captures the regenerative electricity produced during the pumping cycle, stores it in high-performance supercapacitors, and releases it instantaneously during the motor’s next high-demand phase.

By recycling this "lost" power, we transform the pumping unit into a high-efficiency closed-loop system, reducing reliance on traditional energy sources and lowering the environmental footprint of oil production.

Proven Performance & Technical Impact

The integration of STC technology delivers measurable improvements across all key electrical and operational parameters:

  • Energy Savings: Reduces overall energy consumption by 10% – 20%.

  • Power Quality: Increases the Power Factor to 0.99, ensuring maximum electrical efficiency.

  • Grid Relief: Reduces transformer load by 78% and reactive power demand by 79%.

  • Operational Efficiency: Electricity consumption per ton of liquid is reduced by 29.37%.

  • System Synergy: When combined with motor optimization and microgrid (or diesel generator) integration, comprehensive energy savings can reach up to 30%.

Economic Value & ROI

For a standard 15kW model, the STC system can save 13,000 to 26,000 kWh per year. With significant reductions in maintenance and energy costs, the typical Investment Recovery Period (ROI) is only 3 years, making it a highly sustainable upgrade for aging oilfield infrastructure.
