MRINALINI Bose, Project Manager and Advisory of Norwegian-based Rystad Energy, discussed the challenges and opportunities that the rise of the blue economy presents to the traditional oil and gas industry. While sustainable energy poses a threat to conventional fossil fuels, it also offers a chance for legacy industries to lead in the transition by aligning with sustainability mandates. The shift towards sustainable energy does not have to be adversarial, as the expertise in the oil and gas sector can be leveraged to scale the blue economy. However, there is a noted slowdown in sustainable energy investment, with declining demand in hydrogen seen since 2022. Despite this, countries are investing in renewable technologies to diversify energy sources. ESG compliance has become essential for securing investment, emphasizing the need for commercial viability and strong partnerships. Projects like offshore wind and floating solar are gaining traction, especially in maritime economies where oil and gas skills are transferable. The article stresses the importance of moving beyond feasibility into implementation for projects to succeed, highlighting the necessity of clear offtake structures and addressing cost mismatches that can cause projects to stall.
