Abstract

The decarbonisation of the maritime sector is one of the world’s priorities to reduce the volume of polluting emissions. The basis of this decarbonisation is the adaptation of existing ships to emission control regulations by means of transformations, installation of new equipment, development of new low-emission fuels and development of the infrastructure that makes the supply of this new generation of fuels feasible. In addition, hydrogen is the energy vector for all these new technologies, and its role over the next 30 years needs to be addressed. In a changing global situation such as the one we are currently experiencing; this article has the objective of making a review paper on the different fuels currently being used in the maritime sector and the existing alternatives. It also discusses the situation and the impact the current environmental situation has on the world ship order book, both in terms of legislation and economics. As a conclusion, the Liquefied Natural Gas (LNG) will have a very important role to play as a bridge between the current situation and the development of hydrogen technology. Hydrogen is an energy vector that can achieve the decarbonisation objectives by 2050. Storage problems, lack of infrastructures to supply it and the development of technology and regulations are the major challenges it will have to face. Biofuels also present a serious proposal for the decarbonisation of the sector, and the role of hydrogen in their composition, is essential to achieve green fuel generation.

海事部门的去碳化：地平线 2050

海运业的去碳化是全球减少污染排放的优先事项之一。去碳化的基础是对现有船舶进行改造，安装新设备，开发新的低排放燃料，并发展基础设施，使新一代燃料的供应切实可行，以适应排放控制法规。此外，氢气是所有这些新技术的能源载体，其在未来 30 年的作用也需要加以解决。在不断变化的全球形势下，如我们目前所经历的形势，本文旨在就海事部门目前使用的不同燃料以及现有的替代品进行综述。文章还讨论了当前的环境状况及其在立法和经济方面对全球船舶订单的影响。最后，液化天然气（LNG）将在当前形势和氢技术发展之间发挥非常重要的桥梁作用。氢气是一种可以在 2050 年前实现去碳化目标的能源载体。储存问题、供应基础设施的缺乏以及技术和法规的发展是它必须面对的主要挑战。生物燃料也是该领域去碳化的一个重要建议，氢在其组成中的作用对于实现绿色燃料生产至关重要。
