About Biogasclean
Company overview
Biogasclean A/S
Odense, Denmark
2008
What they do
Biogasclean A/S specialises in the design, manufacture, integration, and servicing of advanced gas-treatment technologies focused on biogas. Their core expertise lies in removing hydrogen sulphide and carbon dioxide from raw biogas, upgrading it into biomethane, and converting captured biogenic carbon dioxide into additional methane or other gas products. The company’s technology portfolio includes biological desulphurisation, membrane-based biogas upgrading, biomethane compression, bio-CNG and bio-LNG solutions, as well as carbon capture and utilisation through biological methanation. Their solutions are chemical-free, self-regulating, and suitable for biogas produced by wastewater plants, farms, industrial facilities, and landfills. Biogasclean operates primarily in Denmark and Spain, with commercial and technical activities across broader European markets, and is part of the Cycle0 Group, which develops and operates biomethane infrastructure including grid-injection points (source: biogasclean.com).
Projects & track record
Biogasclean has delivered several notable projects demonstrating its integrated biogas upgrading and methanation technologies. At Nature Energy’s Glansager facility in southern Denmark, the company installed its BE-X biological methanation system, which combines biogenic carbon dioxide with renewable hydrogen to produce e-methane, water, and heat. This project is expected to generate approximately 2–3.5 million cubic metres of e-methane annually, increasing biomethane output by up to 78% from the same feedstock volume, with the transport sector as a key market. In Spain, Biogasclean supplied its UPG-MS membrane upgrading technology to the Alcarràs Bioproductors facility, processing around 500 Nm³ of biogas per hour to produce biomethane that can be compressed as Bio-CNG and injected into the local gas grid via Cycle0’s central grid-injection point. Additionally, Biogasclean supports Cycle0’s Spanish biomethane infrastructure, enabling plants without direct grid access to transport compressed biomethane to central injection facilities. The company is also involved in Cycle0’s Italian expansion, including the Corte Pila brownfield conversion and the Green Park 5 greenfield biomethane plant, with infrastructure investments of approximately €100 million (source: biogasclean.com).
Recent developments
In recent years, Biogasclean has been actively engaged in advancing e-methane technology and expanding its commercial footprint. The company was invited to join a Danish e-methane taskforce established by Biogas Danmark, aimed at exploring the technology, economics, applications, financing, and regulation necessary to commercialise e-methane. Biogasclean is represented on this taskforce by senior personnel including the Senior Sales Manager EMEA and an R&D Specialist. The Glansager biological methanation project marks a significant milestone by integrating methanation into an operating biogas facility and utilising carbon dioxide that would otherwise be removed during upgrading. Biogasclean has also promoted its technologies at European industry events such as Salón del Gas Renovable in Valladolid and Ecomondo in Rimini, signalling a strong commercial focus on Spain, Italy, and the wider European biomethane market (source: biogasclean.com).
Working there
Biogasclean offers roles that combine engineering, biological process expertise, industrial project execution, and commercial development. The company’s activities suggest opportunities in process and mechanical engineering, research and development, project engineering, commissioning, field service, sales, technical sales, customer support, and project management. Employees work primarily from the Odense headquarters, with projects and commercial activities extending into Spain and other European countries. The company’s projects require personnel capable of integrating gas-treatment equipment into existing anaerobic digestion and biomethane plants, supporting installations across borders, and engaging with operators and developers. Ideal candidates often have experience in biogas, anaerobic digestion, gas separation, membrane systems, process control, microbiology, industrial automation, mechanical design, commissioning, or renewable gas infrastructure. Commercial roles focus on selling complex capital equipment and services to wastewater operators, agricultural cooperatives, biogas developers, and biomethane plant owners throughout Europe (source: biogasclean.com).
