Wartsila and Raízen sign bioethanol deal to combat emissions

Raízen and Wärtsilä have entered into a strategic agreement aimed at advancing the decarbonization efforts in the maritime sector. This collaborative initiative focuses on studying the application of ethanol as a marine fuel, with the overarching goal of reducing greenhouse gas (GHG) emissions, offering sustainable fuel alternatives to customers, and actively contributing to the ongoing discourse surrounding the global energy transition in the maritime industry.

Wärtsilä, operating under its fleet decarbonization program, has achieved significant milestones in bringing new sustainable solutions to the market. The company has focused on enhancing engine efficiency and actively supporting the broader decarbonization goals of maritime operations. As part of this collaboration, Wärtsilä will conduct technology tests with ethanol as the primary fuel in its Sustainable Fuels engine laboratories. Additionally, the company will provide support to Raízen in engaging with ship designers and shipowners, addressing regulations and compliance requirements related to the use of cellulosic ethanol as a fuel. This multifaceted agreement aims to drive the integration of clean energy solutions and foster sustainability within the maritime sector.

Initial studies by Raízen suggest that replacing fossil fuels with sustainably produced ethanol in marine transportation could lead to a substantial reduction of up to 80% in CO2 emissions on a standard route from Brazil to Europe. This underscores the potential environmental benefits associated with the utilization of ethanol as a marine fuel and aligns with the broader industry push towards cleaner and more sustainable practices.

The collaboration between Raízen and Wärtsilä represents a proactive step in addressing the pressing environmental challenges within the maritime sector. The focus on ethanol as a marine fuel and the comprehensive approach to technology testing, regulatory compliance, and engagement with industry stakeholders position this partnership as a pivotal contribution to the ongoing efforts to decarbonize and make maritime operations more sustainable.
