Daphne Technology, an industrial decarbonisation company solving the methane slip problem in natural gas engine exhaust, announced the first close of its current round, led by Taranis, a London-based sustainability investor. Taranis will join Shell Ventures and Trafigura as key investors supporting Daphne.
The capital raised will fund the establishment of US manufacturing capacity, support additional product development, and expand field deployment and technical service capabilities. The funding accelerates commercial rollouts targeting midstream and upstream natural gas operators, who face growing regulatory and reputational pressure to reduce methane emissions from their compressor engine fleets.
Methane slip, unburned methane in the exhaust of lean-burn natural gas engines, accounts for 55% of methane emissions from natural gas compressor engines used by pipeline operators and remains largely unaddressed by existing aftertreatment systems.
With Section 136 of the US Clean Air Act and EU ETS regulations targeting methane slip, coupled with a rapidly growing constellation of methane-monitoring satellites, the pressure on land- and marine-engine operators to act is intensifying. The engineering and product advances driven by land-based deployments are also expected to accelerate Daphne´s broader marine product development, targeting emissions from vessel engine exhaust.
SlipPure™ responds directly to this challenge, using a patented plasma-catalytic process to deliver 90% methane reduction alongside removal of 99% of carbon monoxide, 99% of formaldehyde, and 60% of NO₂, with no moving parts, no engine modification required, and, based on Daphne’s analysis, a total cost of ownership significantly lower than the methane penalties outlined in the Clean Air Act. A field demonstration is underway on a 2,000 HP 4-stroke lean-burn engine at a leading US midstream operator.
“Our mission is to solve the methane slip problem at scale, across every natural gas engine that needs it,” said Jamie Brick, Interim CEO of Daphne Technology. “This financing is a key milestone in getting there, and closing it with Taranis, an investor with a deep commitment to sustainable energy solutions, reflects the growing conviction that methane abatement is both a commercial and climate imperative. Forward-thinking operators have moved beyond setting emissions targets to executing on them. SlipPure™ gives them a cost-effective, field-ready tool to do exactly that.”
SlipPure™ has attracted strong interest from leading operators and investors across the US and international energy sector, reflecting growing urgency to address methane slip as both a regulatory and climate priority. Daphne Technology is the only provider offering a validated, scalable methane abatement system specifically for lean-burn gas engines. The company is currently working with a leading US midstream operator and a supermajor on a field demonstration, with interest from additional infrastructure and power sector players with large gas engine fleets.
“Successfully tackling the impact of methane as a warming gas will be a turning point in reducing emissions worldwide,” said David Sorin, Managing Director at Taranis. “Our investment in Daphne reflects Taranis’ commitment to delivering this turning point through technological advancement that makes decisive impact to methane abatement.”
Headquartered in Ecublens, Switzerland, with offices in Houston and Singapore, Daphne Technology employs a team combining deep expertise in plasma chemistry, catalysis, oil and gas engineering, and industrial scale-up. The company plans to expand its US operations the coming months, with a focus on field and product engineering, business development, and operations.
