Mark Dixon (MD): While there are many similarities between fixed and floating offshore wind turbines, the opportunities come from the differences. 1 How do you see its potential compared to fixed structures? 1.) is expected to double nine times in the next 30 years, opening up deepwater sites in many more countries and unlocking the second phase of the energy transition. WO: Research has suggested that installed capacity of floating wind (Fig. It must remain a vital element in the transition journey for decades to come, but emissions must be cut significantly to make production greener, thereby providing the social license to operate through the transition. That would seriously compromise the sector’s role in homegrown energy security. If assets don’t reduce their CO 2 emissions by the mid-2020s, increased emissions penalties through carbon taxes will see many North Sea fields become uneconomical, moving them towards decommissioning by the end of the decade, at the cost of thousands of jobs. Having worked on large-scale offshore infrastructure developments in the UK sector for more than 25 years, how do you feel this drive to decarbonize is fairing?ĭan Jackson (DJ):The UK has set world-leading targets to progress energy transition, but to achieve them there must be a greater sense of urgency and joined-up thinking. World Oil (WO): The oil and gas industry is contending with increased pressure to fulfil its net zero ambitions. Dan Jackson and Mark Dixon, co-founders of Cerulean Winds, discuss the needs and challenges associated with wind-powered electrification and asset conversion. For example, in 2017, the Hywind floating wind farm off the northeast coast of Scotland was the first in the world to be brought into operation.Īs the fossil fuel industry grapples with its net zero target ambitions, switching gas turbine generation to 100% green power from neighboring wind turbines could be an efficient and sustainable step in the right direction. The sensitivity analysis further shows thatthe distance from wind turbine factory to wind farm site has more significant influence on the life-cycle GHG emission intensities of both onshore and offshore wind turbines than that from wind farm site tothe recycling and landfill locations, suggesting that the wind farm site and the wind turbine factoryshould be as close as possible.Mark Dixon and Dan Jackson, co-founders of Cerulean Windsįloating offshore wind is widely acknowledged as the answer to exploit deepwater sites with abundant wind resources. The sensitive analysis shows that the lifetime and energy production of wind turbine have largeinfluences on the GHG emission intensity of both onshore and offshore wind turbines, implying that it isan effective way to prolong the lifetime of wind turbine and increase the energy production of windturbine to reduce the GHG emission intensity of wind turbine. If the installed wind turbines in 2014 displace coal, the savedGHG emissions can roughly reach 5.08x10 7tCO 2-eq, accounting for 0.09% of global GHG emissions in2012. Onshore and offshore wind turbines have much smaller life-cycle GHGemission intensity than coal power plants. Results show that the life-cycle GHG emission intensity is 0.082 kg CO2-equivalent (eq)/Mega-joule (MJ) for onshore wind turbine and is 0.130 kg CO 2-eq/MJ for offshore wind turbine, respectively.Offshore wind turbine has larger life-cycle GHG emissions than onshore wind turbine, owing to thefloating platformfixed in sea. The paper uses lifecycle assessment (LCA) to estimate the life-cycle greenhouse gas (GHG) emissions of onshore andoffshore wind turbines with the nominal capacity of 2 MW, to advance our understanding of onshore andoffshore wind energy and to inform policy, planning, and investment decisions for future growth of windpower. Onshore and offshore wind turbines may have different environmental sustainability due to their owncharacteristics, and this information is important for future growth of wind power.
