RepAir Carbon opens a Luxembourg office to scale its electrochemical carbon capture tech across Europe

The Israeli deeptech, which uses 70% less energy than conventional carbon capture methods and has already signed with Shell, Mitsubishi, and C-Questra, is expanding into Europe’s industrial decarbonisation market as EU regulatory frameworks mature.

RepAir Carbon, the Israeli developer of electrochemical direct air capture technology, has opened a European office in Luxembourg, the company announced today.

The expansion is being led by Jean-Philippe Hiegel, VP Strategy & Growth, who joins from a seven-year stint building out carbon capture and storage infrastructure at Northern Lights in Norway, the world’s first commercial CO₂ transport and storage joint venture.

He will head RepAir’s European operations from Luxembourg.

RepAir’s technology addresses one of the fundamental problems with conventional carbon capture: it is extraordinarily energy-intensive, which makes it economically unviable for the diluted CO₂ streams that make up most industrial emissions.

The company’s solid-state electrochemical system captures CO₂ at concentrations below 5%, covering gas turbines, aluminium smelters, and atmospheric air, without heat, liquids, or solvents, consuming 70% less energy than conventional methods.

The device works like a battery-inspired electrochemical cell: electrodes separated by a membrane react with CO₂ in air or flue gas drawn into a reaction chamber, concentrating and capturing it in a single step. BloombergNEF has recognised RepAir among 14 leading DAC companies globally for this approach.

The commercial pipeline is already live. RepAir is a technology provider for the Pelican Gulf Coast Carbon Removal DAC hub in Louisiana, a project involving Shell, Mitsubishi, Louisiana State University, and the University of Houston, with $4.9 million in US Department of Energy grant support.

In Europe, RepAir partnered with Dutch carbon storage startup C-Questra in 2024 to develop the EU’s first onshore Direct Air Capture and Storage project, sited in Grandpuits near Paris. The company also has active projects in Texas and Greece.

The Luxembourg office extends this European footprint and aligns RepAir directly with the EU’s regulatory pipeline: the Carbon Removal Certification Framework, CDR buyer’s club mechanisms, and ReFuelEU Aviation, which creates sustained demand for CO₂ feedstock sourced from atmospheric or industrial capture.

RepAir will participate in Luxembourg’s CCUS & CDR Taskforce, a national initiative launched in December 2025 by the Ministry of Economy and the Ministry of Environment, Climate and Biodiversity to advance the country’s carbon management framework.

For RepAir, Luxembourg offers proximity to European industrial partners, access to climate-focused investors, and a multilingual international talent pool. The expansion follows the company’s $15 million Series A extension raised in April 2025, co-led by Taranis Carbon Ventures and Extantia Capital with participation from Ormat Technologies and Repsol. The Israeli Innovation Authority also contributed a $3 million non-dilutive grant as part of that round.
