Product Overview

Overview

At Daphne Technology, we specialize in reducing methane emissions from gas-powered engines, both on land and at sea.

  • SlipPure™ is Daphne's advanced exhaust cleaning system designed to remove methane and other regulated gases from engine exhaust, helping operators achieve significant emission reductions and meet regulatory compliance. Whether applied to four-stroke lean-burn engines in natural gas operations or dual-fuel engines in maritime settings, SlipPure™ enables industries to reduce their environmental footprint and align with global climate goals.

  • PureMetrics™ complements this by providing precise, continuous, and direct emissions monitoring. This innovative system ensures transparency, real-time data collection, and compliance with emissions standards, empowering operators to make informed decisions and improve their environmental performance.

Business Model

Daphne Technology offers flexible pricing models tailored to the needs of its customers:

  • SlipPure™: Pricing is project-based, customized to the scale and requirements of each installation to ensure optimal methane abatement solutions.

  • PureMetrics™: Available through a Hardware-as-a-Service (HaaS) subscription model, combining cutting-edge emissions monitoring hardware with ongoing support and services for seamless integration and reliable performance.

Technology Innovations
  • Lower Temperature Methane Oxidation: Combines non-thermal plasma with a patented catalyst, enabling efficient reactions at lower temperatures.

  • Patent-Protected Plasma-Catalysis System: SlipPure™ converts methane into less harmful substances, significantly reducing methane slip, carbon monoxide, formaldehyde and NOx.

  • Continuous Emissions Monitoring: PureMetrics™ delivers real-time, accurate measurements of exhaust gas emissions.

  • Performance Tracking and Benchmarking: Tracks emissions trends, CO₂ benchmarking, and future CO₂ taxation exposure.

Applications
  • Methane emissions from gas engines: Addressing the challenge of methane slip in exhaust from gas-powered engines on land and at sea.
  • Compliance with stringent regulations: Helping operators meet global environmental standards for emissions reduction.
  • Scaling methane abatement technology: Offering modular, scalable solutions for diverse applications across industries.
  • Lack of accurate emissions data: Providing real-time, continuous monitoring to ensure reliable emissions measurement and reporting.
  • Greenhouse gas reporting challenges: Enabling transparent and precise reporting to align with international frameworks.
  • Collaborative innovation: Partnering with stakeholders to deploy impactful methane abatement projects tailored to industrial needs.
