Lauren Eatwell, Head of Engineering at BAR Technologies, is the innovative mind behind the WindWings project, which retrofits cargo ships with sails to harness wind energy. She discusses the maritime industry's significant contribution to global emissions and the ambitious goal of decarbonization. Key topics include the practical advantages of wind technology for fuel efficiency, the industry's slow adoption of sustainable practices, and the necessity for global collaboration and innovation in reducing shipping's carbon footprint.
The maritime industry contributes approximately 3% of global emissions, necessitating innovative solutions like WindWings to enhance sustainability in shipping.
WindWings technology retrofits ships with large sails, potentially saving up to 30% in fuel consumption while promoting the adoption of greener practices.

Innovative Energy Solutions from Morocco
The discussion highlights the innovative energy project being developed by X-Links, which aims to connect Morocco's abundant renewable energy resources to the UK through subsea intercontinental cables. This initiative seeks to leverage Morocco's strong solar and wind capabilities to provide power to areas of high demand, such as the cold and rainy UK. X-Links is projected to generate sufficient energy to supply around 7 million UK homes, reinforcing the potential of international renewable energy collaborations. The project intends to operate without government investment while simultaneously promising significant financial contributions to the UK economy.
Decarbonizing the Shipping Industry
The maritime industry is under scrutiny for its contributions to greenhouse gas emissions, accounting for approximately 3% of the global total. This sector presents unique challenges in decarbonization, as it often operates out of sight, rendering its environmental impact less visible to the public. Significant innovation is required to develop viable solutions, and the conversation emphasizes the need for a shift in focus from solely alternative fuels to incorporate wind propulsion technologies. The integration of wind sails onto cargo ships can significantly reduce fuel consumption, highlighting the importance of advancing toward sustainable practices in shipping.
Wind Wings Technology Explained
The podcast delves into the specifics of Wind Wings, a technology that involves the installation of large sails on cargo ships to harness wind power and enhance fuel efficiency. These sails are designed to reach heights of approximately 40 meters and adjust their shape based on wind direction, allowing for optimal thrust and reduced fuel use. Depending on the shipping routes and prevailing wind conditions, these wind wings can lead to fuel savings of up to 30%. This innovative approach not only complements existing engine technology but is also seen as a practical retrofitting option for current vessels.
Challenges and Opportunities in Maritime Innovation
The conversation touches on the hurdles faced by the maritime industry in adopting innovative technologies like Wind Wings. Resistance to change is common, particularly in a sector that has maintained traditional practices over decades. However, improvements in fuel taxes and regulations are creating a pressure to adopt greener technologies, which is fostering a more accepting environment for innovation. By demonstrating tangible benefits and securing independent verification of their savings, companies are beginning to shift perceptions and embrace new approaches to sustainability.
The maritime industry is responsible for roughly 3% of global emissions. So one solution to help reduce fuel consumption has already set sail. Head of Engineering at BAR Technologies, Lauren Eatwell has steered a project called WindWings which retrofits large steel and glass sails to ships. But will the wider industry move fast enough to meet climate targets?
