HPDD v26: The Hydraulic Prime Mover for Industrial Heat Pumps

Bridging the Gap Between Grid Congestion and High-Grade Process Heat.

The industrial transition to high-temperature heat pumps (HTHP) is often stalled by two factors: grid capacity and temperature limits. The HPDD v26 TRT solves both. By replacing electric motors with a direct-drive hydraulic power pack, we enable MW-scale thermal output without the need for a grid upgrade.

Why Drive Your Heat Pump with HPDD?

1. Grid-Independent Thermal Autonomy

Deploy megawatt-scale heat pumps anywhere. The HPDD platform converts green ammonia or hydrogen directly into high-pressure hydraulic power to drive your compressors.

  • No electrical infrastructure upgrades required.

  • Fuel-to-Hydraulic efficiency of 62.0% LHV.

  • Bypass grid congestion and peak-shaving costs.

2. The 230°C Thermal Cascade

Standard electric heat pumps struggle to reach the temperatures required for industrial process steam. The HPDD v26 creates a unique Thermal Cascade:

  • Combined Output: Integrate the heat pump’s output (typically 90°C–120°C) with the HPDD’s constant 230°C isothermal waste heat.

  • Steam Generation: This synergy allows for the efficient generation of process steam, a milestone currently out of reach for traditional decentralized heat pump systems.

3. Operational Resilience

Designed for continuous industrial duty, the HPDD platform offers:

  • 30,000+ Hour Service Life: Enabled by our zero-contact Active Nitrogen Ring (ANR) architecture.

  • Compact Footprint: High power density compared to bulky electric-drive configurations.

  • Real-Time Adaptability: Precision control of hydraulic flow to match the variable load requirements of industrial thermal cycles.

Technical Specifications (HTHP Integration)

  • Drive Type: Direct Hydraulic Output (Proprietary Pump Interface)

  • Prime Efficiency: 62.0% LHV

  • Secondary Heat Grade: 230°C (Siloxane-based loop)

  • Emissions: Soot-free; < 10 ppm NO_x

  • Control: Integrated Digital Twin feedback for automated COP optimization.

 

How it Works: The HPDD Thermal Synergy Path

The HPDD v26 TRT does not just provide power; it creates a dual-stream energy flow that maximizes every joule of your green fuel.

Step 1: The High-Pressure Prime Cycle

Green ammonia or hydrogen is inducted at 600-bar, achieving a 62.0% LHV conversion into high-pressure hydraulic energy. This energy drives the heat pump’s compressor directly, bypassing the 10-15% losses typically seen in Grid-to-Transformer-to-Motor conversions.

Step 2: The Low-Grade Heat Lift

The industrial heat pump draws energy from a low-grade source (e.g., ambient air or waste water), "lifting" it to a useful process temperature of 90°C – 120°C.

Step 3: The 230°C Thermal Injection (The "Multiplier")

Simultaneously, the HPDD’s isothermal cooling loop captures high-grade heat from the combustion cylinders. Unlike traditional engines that waste this energy, we maintain this loop at a constant 230°C.

Step 4: Steam-Grade Output

By injecting the HPDD’s 230°C stream into the heat pump’s 120°C output, the system achieves a thermal cascade. This combined energy stream provides the necessary enthalpy to generate High-Pressure Process Steam, effectively solving the "temperature gap" that has previously limited industrial electrification.

The Efficiency Math

"By combining a COP of 3.8 from the heat pump with the 62% mechanical efficiency and the 230°C waste-heat recovery of the HPDD, the system delivers a significantly higher Thermal Megawatt output per kilogram of fuel compared to any boiler or electric-only alternative."
