By 2050, hydrogen fuels may be able to reduce ship emissions by up to 80%

By mid-century, fast substitution of fossil fuels with renewable fuels based on green hydrogen and advanced biofuels might allow the worldwide marine industry to decrease CO2 emissions by up to 80%. That’s according to a recent analysis from the International Renewable Energy Agency (IRENA), an international organization tasked with assisting countries in their transition to a more sustainable energy future. By the year 2050,

“Decarbonizing global shipping is one of the most difficult industries to handle, and existing plans fall short of what is required,” says IRENA Director-General Francesco La Camera. “Our forecast clearly demonstrates that using green hydrogen fuels to reduce CO2 emissions in such a key, difficult-to-abate industry is technically possible.”

A Pathway to Decarbonize the Shipping Sector by 2050, a new research from IRENA, lays forth a path for the global shipping sector to meet global climate objectives by 2050. Renewable fuels should account for at least 70% of the sector’s energy mix by 2050, according to the group, in order to meet climate targets.

“It’s important to respond quickly,” La Camera stated. “May this study inspire policymakers, shipowners and operators, port authorities, renewable energy providers, and utilities to collaborate on common climate goals and demonstrate their commitment to world leaders at the United Nations Climate Conference COP26 in Glasgow.”
