What Daphne Technology does

Daphne Technology SA is a Swiss climate-tech company headquartered in Ecublens, Switzerland, founded in 2017 and operating in the methane slip abatement segment for natural gas engines. The company has developed a proprietary plasma-catalytic process, branded as SlipPure, that destroys methane in the exhaust of gas-powered engines and converts it into non-hazardous by-products. Its product portfolio comprises three core offerings: SlipPure Land for 4-stroke lean-burn natural gas engines used by pipeline and midstream operators; SlipPure Marine for dual-fuel marine engines serving shipowners and charterers; and PureMetrics, a continuous emissions monitoring and reporting system that has received DNV Statement of Compliance and Lloyd's Register Factual Statement for direct reporting under EU MRV and IMO DCS frameworks.

The company targets two primary enterprise segments: oil and gas operators (midstream and upstream) facing methane regulation under the U.S. Clean Air Act, and maritime operators exposed to EU ETS and FuelEU Maritime obligations. Customer evidence to date is concentrated in pilots and field demonstrations, including deployments with Williams under a USD 6 million U.S. Department of Energy grant, a first-of-kind shipboard pilot with Maran Gas completed in October 2025, and ongoing field work with a leading U.S. midstream operator and an unnamed supermajor. The investor base comprises strategic energy and commodities investors — Shell Ventures, Saudi Aramco Energy Ventures, Trafigura, and AET — alongside a sustainability-focused lead investor (Taranis) in the most recent CHF 15 million first close announced in April 2026.

Daphne Technology generates revenue from hardware sales and installation of SlipPure systems combined with recurring PureMetrics monitoring subscriptions, sold via direct enterprise field sales on quote-based multi-year contracts. Headcount is in the 11-50 range, the company is privately held, and it has cumulatively raised approximately CHF 35-38 million in equity, grant, and crowdfunding capital. The company received SPE ATCE Startup Village Rising Star and People's Choice awards in October 2025 and is establishing U.S. manufacturing capacity to scale field deployment.

Core offering

Daphne Technology develops and sells plasma-catalytic methane slip abatement systems and emissions monitoring software. Its SlipPure Land and SlipPure Marine systems treat exhaust from gas-powered engines to reduce methane emissions on land and at sea, while the PureMetrics software provides continuous emissions monitoring and regulatory reporting for shipowners, charterers, and oil & gas operators.

Product overview

Daphne Technology is a methane reduction company offering a portfolio of products focused on methane slip abatement for gas-powered engines. The product lineup consists of three core offerings: SlipPure™ Land for land-based 4-stroke lean-burn natural gas engines, SlipPure™ Marine for marine dual-fuel engines, and PureMetrics™ for continuous emissions monitoring and regulatory reporting. SlipPure products use plasma-catalytic technology to convert methane emissions into non-hazardous by-products, while PureMetrics enables real-time data collection and compliance reporting to EU MRV and IMO DCS.

Scale indicators5 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Alfa Laval: Swedish industrial incumbent supplying marine exhaust gas cleaning systems (scrubbers) and heat exchangers globally. Comparable to Daphne's SlipPure Marine as a broad-based marine emissions control incumbent with deep shipyard relationships, although Alfa Laval's scrubber technology addresses SOx rather than methane slip.
• Wärtsilä: Finnish marine technology and engine manufacturer offering lifecycle services and emission reduction solutions (including scrubbers and future-fuel readiness) for shipowners. Overlaps with Daphne on marine engine exhaust emissions compliance, though Wärtsilä is also an engine OEM that could vertically integrate methane abatement.
• INNIO Jenbacher: Austrian gas engine manufacturer (Jenbacher) for oil & gas, industrial, and power generation applications. A natural customer for SlipPure Land and a potential competitor if INNIO bundles methane abatement into engine offerings.
• Caterpillar Oil & Gas: Major OEM of gas engines used in oil & gas compression and pipeline operations. Comparable as both a potential customer for SlipPure Land (engine retrofit programs) and a competitive threat if Caterpillar develops in-house methane slip solutions.
• WinGD: Swiss marine engine developer specializing in low-pressure dual-fuel engines for LNG carriers and large vessels. Directly adjacent to Daphne's SlipPure Marine value proposition since WinGD's engines are the primary source of methane slip that SlipPure Marine addresses.
• Aker Carbon Capture: Norwegian provider of post-combustion carbon capture solutions for industrial point sources. Comparable as a publicly listed climate tech hardware company addressing industrial emissions compliance, though focused on CO2 rather than methane slip.

Direct peers

• CleanAir Technology: Specialist provider of marine exhaust gas cleaning systems (scrubbers) for SOx compliance. Most directly comparable to Daphne's SlipPure Marine as a focused emissions control hardware company serving the same shipowner and charterer buyer.
• Yara Marine Technologies: Provider of maritime emissions monitoring and compliance solutions for shipowners. Closest direct competitor to Daphne's PureMetrics product line, addressing the same regulatory reporting workflows (EU MRV, IMO DCS, CII).

Emerging players

• CarbonOrO: Emerging point-source carbon capture technology company serving industrial emitters. Comparable to Daphne as a focused emissions control hardware startup targeting hard-to-abate industries with novel process technology.
• Highwood Emissions Management: Oil & gas methane emissions measurement, reporting, and verification (MRV) specialist. Comparable to Daphne's emissions monitoring capability (PureMetrics) and adjacent as a methane-focused services provider for upstream and midstream operators.
