Study Puts Shipping's Green Hydrogen Switch at 129,458 Averted Deaths a Year
A worldwide switch to green hydrogen in shipping could avert 129,458 premature deaths each year, according to a Nature Communications study reported by Hydrogen Fuel News.
The same study puts the annual health benefit of that switch at USD 284 billion, derived from lower PM2.5 and ozone emissions from marine fuel combustion.
The peer-reviewed work was led by Professor Steve Hung-Lam Yim of the Asian School of the Environment at Nanyang Technological University and published in Nature Communications, Hydrogen Fuel News reported.
The mortality figure and the monetized benefit both rest on the same mechanism: replacing combustion fuels in marine engines cuts the fine particulate matter and ozone precursors that shipping emits into coastal air. Yim's team framed the result as conditional on a global shift rather than a partial one.
