Emigreen

What Emigreen does

Emigreen B.V. is a Dutch specialty manufacturer of exhaust gas aftertreatment systems for marine diesel engines, founded around 1999-2005 and headquartered in Hendrik-Ido-Ambacht near Rotterdam. The company designs and produces integrated Selective Catalytic Reduction (SCR) systems, marketed as the MINOx line (with S and M variants for lower- and higher-power engines), and Diesel Particulate Filter (DPF) systems, including the active AlfaAlfa burner-based regeneration platform and the passive Delta system. Its core technology uses urea injection with NOx sensor feedback to reduce NOx emissions by up to 70-75% and monolithic ceramic filters to remove up to 99% of soot particles, with integrated silencers delivering 35-45 dB(A) attenuation. A proprietary control system manages engine monitoring, automatic regeneration, and alarm integration. The flagship product line addresses IMO Tier III, EU Stage V, and the Bureau Veritas Ultra Low Emission Vessel (ULEV) voluntary notation; Emigreen's systems are CE- and MED (Wheelmark)-certified for marine deployment.

Emigreen sells custom-engineered, project-based solutions primarily to enterprise customers: ship owners, shipyards, and engine manufacturers in the maritime sector, with the superyacht and commercial shipping verticals as primary segments and energy generation and industrial applications as secondary verticals. Revenue is generated through hardware sales of complete SCR/DPF systems (new build and retrofit) and professional services including commissioning, Factory Acceptance Tests, and field maintenance. The company maintains an international distributor network and a strategic partnership with Halyard for the superyacht channel, supplemented by direct sales from its headquarters team. Pricing is not publicly disclosed; systems are quoted on a project basis.

The company operates as a privately held, founder-led business under Managing Director Niko Dalpis, with no disclosed institutional investment, parent company, or subsidiaries. It has 11-50 employees and serves a global installed base that includes dredging operators (Jan De Nul Group), inland shipping (MCS Anda), superyacht builders (Feadship), hybrid cargo vessels (MVS Goblin), and industrial sites. Notable performance claims include a 30,000+ operating-hour record on a single barge installation and product lifespans exceeding 15 years for units commissioned since 2005.

Core offering

Emigreen B.V. designs, manufactures, and supplies integrated exhaust gas aftertreatment systems for marine diesel engines. Their product portfolio includes Selective Catalytic Reduction (SCR) systems for NOx reduction and Diesel Particulate Filter (DPF) systems for soot removal, with integrated exhaust silencers. Systems are custom-engineered to fit specific engine specifications and confined installation spaces, and can be installed on new ships or retrofitted on existing vessels.

Product overview

Emigreen offers integrated emission control solutions for marine diesel engines, combining Diesel Particulate Filter (DPF) systems for soot removal and Selective Catalytic Reduction (SCR) systems for NOx reduction, with integrated exhaust silencing. The product portfolio centers on the MINOx SCR product line (available in S for lower power and M for higher power engines) and DPF systems (AlfaAlfa active regeneration and Delta passive regeneration models). All systems are custom-engineered to fit specific engine parameters and confined installation spaces, featuring programmable control systems that autonomously monitor engine parameters, manage regeneration cycles, and adjust urea dosing based on NOx sensor feedback.

Products and services

• MINOx SCR System Selective Catalytic Reduction system that reduces nitrogen oxide (NOx) emissions from marine diesel engines by converting harmful gases into inert nitrogen and water vapor using aqueous ammonia/urea solution injection. Designed to meet or exceed IMO Tier III limits.
• MINOx S Compact SCR system designed for lower power output engines, adjustable in steps of 7.5 l/hr up to 22.5 l/hr urea injection capacity. Includes injection spool, SiGAS silencer, NOx spool, S1-3 dosing unit, and control cabinet.
• MINOx M SCR system designed for higher power output engines with urea injection capacity up to 50 l/hr. Includes M dosing unit, air unit, and control cabinet.
• DPF System (Diesel Particulate Filter) Monolithic ceramic filter that removes up to 99% of soot particles from diesel engine exhaust gases, with filter regeneration capabilities to burn off accumulated particulate matter.
• Emigreen AlfaAlfa Active DPF system with integrated fuel burner that artificially raises temperature to initiate filter regeneration. Enables 3,000-4,000 engine running hours between ash removal, with crew-maintainable filter elements.
• Emigreen Delta Passive (self-regenerating) DPF system that relies on naturally high exhaust temperatures to burn off accumulated soot without additional heating.
• Exhaust Silencer / Noise Reduction System Acoustic treatment system that attenuates exhaust noise across low, medium, and high frequency bands. Integrated with aftertreatment housings to minimize back pressure while achieving 35-45 dB(A) attenuation.
• Integrated Emission Control Solutions Custom-engineered combined DPF and SCR systems for marine diesel engines, tailored to specific engine specifications and space requirements. Includes sophisticated control systems for continuous monitoring of engine parameters and automatic regeneration.
• Commissioning and Maintenance Services On-site commissioning, installation oversight, Factory Acceptance Tests (FAT), and ongoing field service and maintenance of SCR and DPF systems on marine vessels worldwide.

• Tenneco / Clean Air Technologies (marine division): Large global emission-control manufacturer with deep automotive SCR/DPF expertise that occasionally extends into marine and stationary applications. Competes indirectly with Emigreen via scale advantages in catalyst and filter manufacturing.
• MAN Energy Solutions: Large marine engine manufacturer offering integrated SCR and exhaust aftertreatment solutions as part of its two- and four-stroke engine portfolio. Competes with Emigreen on bundled newbuild engine packages and tier-III-ready configurations.
• Alfa Laval: Global marine environmental systems incumbent offering EGR scrubbers, PureCool SOx scrubbers, and broader emission-control hardware. Competes with Emigreen on marine emissions but as one product line within a much larger marine portfolio.

Emerging players

• Marine Exhaust Solutions: U.S.-focused supplier of marine exhaust aftertreatment and emission compliance solutions for commercial and workboat markets. Comparable product offering (DPF/SCR for marine diesels) but with primary geographic focus on North America.
