Daphne Technology’s innovative SlipPure™ system has been awarded Approval in Principle (AiP) by Lloyd's Register (LR) for its Plasma-Catalytic technology. The solution improves efficiency by lowering plasma power consumption, enabling very high methane slip reductions at exhaust temperatures well below those required for catalyst-only solutions.
The advanced SlipPure™ system, which previously received AiP for its plasma-only configuration, now runs its full Plasma-Catalytic process and has undergone several rigorous test campaigns, utilising exhaust gas produced from a land-based test engine (746kW lean burn spark ignited engine type RR MTU 8V4000M55RN) installed at the Maritime Center of the University of Applied Science in Flensburg, Germany.
Methane slip is a major contributor to greenhouse gas emissions, with a global warming potential 28 times greater than that of CO2 over a 100-year period.
In January 2023, safe operation of the WPP power supply in the plasma-only system was demonstrated over nearly 75 hours of operation. Earlier this year, the Plasma-Catalytic process was evaluated over nearly 100 hours of operation, and LR witnessed 4.0 g/kWh removal of methane slip (62% methane slip reduction at 75% load) from exhaust gas with temperatures as low as 380 °C.
"We are again very honoured to be working closely with Lloyd's Register and delighted to receive this AiP," said Dr Mario Michan, CEO and Founder of Daphne Technology. "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, said: “LR has been working with Daphne Technology for several years and following recent testing, it’s clear that its Plasma-Catalytic technology is moving the bar in helping companies to meaningfully mitigate methane slip in the maritime and land-based oil and gas industries."
