POWLESS

The POWLESS project objective is to demonstrate the utilization of high-efficiency turbo heat pumps (COP 10) for biogas upgrading. Nature Energy participates as a project partner and will be hosting the first-of-akind installed high temperature turbo heat pump developed by Weel & Sandvig (W&S). Potential customers will benefit significantly from this technology by reducing the energy load and any fossil emissions in the biogas production.

The aim is to show-case a first-of-a-kind high temperature heat pump for potential customers.

The overall goal is to install heat pump with a power consumption of 100 kW and a heat generation of 1 MW, resulting in a COP up to 10. The high COP value is possible due to the high-speed heat pump developed by (W&S).

This project builds on experience from several ongoing and related development projects. In this project we will combine two new technologies into a third technology, POWLESS:

1. High speed heat pump
2. Advanced amine scrubbing with heat integration

The combination of the two technologies can eventually lead to significant reduction of energy consumption, below 1 GJ/ton which is a significant reduction compared to the standard 3.7 GJ/ton.
