Daphne Technology’s SlipPure System Achieves Lloyd’s Register Approval


Daphne Technology’s innovative SlipPure™ system has received Approval in Principle (AiP) from Lloyd’s Register (LR) for its Plasma-Catalytic technology. This cutting-edge solution enhances efficiency by reducing plasma power consumption and achieves significant reductions in methane slip at exhaust temperatures significantly lower than those required for catalyst-only systems.

Background and Testing

The advanced SlipPure™ system, which previously received AiP for its plasma-only configuration, now fully incorporates the Plasma-Catalytic process. It has been rigorously tested using exhaust gas from a land-based 746kW lean burn spark-ignited engine (RR MTU 8V4000M55RN) at the Maritime Center of the University of Applied Science in Flensburg, Germany.

Environmental Impact

Methane slip is a significant contributor to greenhouse gas emissions, with a global warming potential 28 times greater than CO2 over a 100-year period.

Test Results

In January 2023, the WPP power supply’s safe operation in the plasma-only system was demonstrated over nearly 75 hours. Earlier this year, the Plasma-Catalytic process was evaluated over nearly 100 hours, with LR witnessing a 4.0 g/kWh methane slip removal (a 62% reduction at 75% load) at exhaust gas temperatures as low as 380 °C.

Statements from Daphne Technology and Lloyd’s Register

Dr. Mario Michan, CEO and Founder of Daphne Technology, expressed gratitude for the continued collaboration with Lloyd’s Register and the AiP recognition. He stated, “This approval in principle validates our innovative approach, and the witnessed results are a testament to the efficacy and reliability of our SlipPure™ system. The performance results demonstrate our technology’s readiness for market deployment and its impact on reducing methane emissions.”

Panos Mitrou, Lloyd’s Register Global Gas Segment Director, commented on the long-standing partnership with Daphne Technology and acknowledged the advancements in Plasma-Catalytic technology, stating that it significantly aids companies in mitigating methane slip in both the maritime and land-based oil and gas industries.
