Decarbonization of Shipping – Emerging Alternative Fuels from a US Perspective
Maritime attorney Sean Pribyl authored an article for Gard analyzing decarbonization efforts in the shipping industry. According to the U.S. Environmental Protection Agency, transportation contributes about 14 percent of global greenhouse gas emissions, with shipping alone contributing 2-3 percent. In response, the International Maritime Organization created an ambitious strategy to halve greenhouse gas emissions by 2050 and reduce the carbon intensity of shipping by 40 percent by 2050; other initiatives are working on the development of commercially viable zero-emission vessels. However, as Mr. Pribyl explains, decarbonization is not a "one-size-fits-all" endeavor, and meeting these climate goals will require the use of a variety of alternative fuels. In this article, he looks at the top contenders to replace heavy fuel oil, including liquefied natural gas, hydrogen and fuel cells, and electric and hybrid systems.
