Italian firm Ecospray and German green energy firm Ruhe Agrar signed agreements to supply two biomethane plants and three CO2 liquefaction plants for customers of Green Line Liquid Anlagenbau, an affiliated company of Ruhe company group
Each project involves the construction of a complete system for pretreatment, upgrading, liquefying biomethane and CO2, with associated storage and cryogenic tank filling. The first project is expected to produce 8 tonnes of bioLNG per day, while the second is set to produce 3 tonnes per day, the same quantity as the project that started the collaboration between Ecospray and Ruhe in 2021.
Both companies are banking on bioLNG and expect the demand for biomethane liquefaction in the German market to increase. The decentralised standardised module, which can be set up for biogas plants from an electrical power source of 500 kW and higher, allows biogas plants to work after the end of the German Renewable Energy directive, especially for biogas plants with a high proportion of liquid manure, manure and residues.
Ruhe Biogas Service chief technical officer Boris Drewes remarked, “The technology is easy to use and we can offer it as a standard product for various plant sizes. Our goal is to establish this product together with our partners for the decentralised production of alternative fuels in Germany and Europe.”
"We share the same vision as Ruhe and the same trust in this technology as a tool for achieving decarbonisation by 2050," added Ecospray president Maurizio Archetti.
“The construction of these new plants, which also include CO₂ capture and liquefaction, is a significant milestone in our journey towards the creation of clean energy for a zero-emissions planet. The development of various carbon-capture technologies is one of the projects we are investing most in, not only for land transport but also for the marine sector."
Ecospray specialises in integrated services for the green conversion of the maritime and land industries and reduced dependency on fossil fuels. The company is part of the Carnival Group and manufactures compact turnkey systems for the pretreatment and advanced upgrading of biogas from agricultural plants, water purification sludge and landfills for feeding into the network and biomethane micro-liquefaction systems.
