Core Power's latest white paper “Powering Progress: E-Fuels for Sustainable Shipping” delves into the alternative marine fuel landscape, with a focus on e-fuel production. E-fuels, synthetic liquid fuels produced through electrical processes converting water and CO2 into usable products, are seen as a sustainable replacement for traditional fossil fuels. The white paper emphasizes the importance of advanced nuclear technology in scaling up e-fuel production. By 2050, the global demand for e-fuels is projected to reach around 20,000 TWh annually, necessitating significant electrical energy. The paper also discusses various hydrogen production methods like grey, blue, green, and pink hydrogen, outlining the transition towards cleaner energy sources. Different maritime e-fuels such as e-ammonia, e-methanol, e-diesel, and e-methane are explored, each offering unique advantages for shipping applications. E-ammonia is highlighted as a promising marine fuel, while e-diesel stands out for its compatibility with existing engines and fuel tanks. Additionally, e-methane faces challenges in scaling production but shows potential for wider adoption. The white paper serves as a comprehensive guide to the evolving landscape of sustainable marine fuels, promoting a positive outlook on the future of e-fuels in the maritime industry.
