Burning ammonia doesn’t emit carbon dioxide but it does release fine particulate matter that contributes to about 8 million premature deaths globally every year. Read more at straitstimes.com.
TOKYO – Japan’s plan to co-fire coal power plants with ammonia in a bid to decarbonise its electricity sector could increase a different type of air pollution linked to millions of premature deaths globally each year, according to new analysis.
The authors estimated emissions for Jera Co’s Hekinan Thermal Power Station Unit 4, which has been revamped over the past few years to allow it to use both coal and ammonia. Co-firing the facility with 50 per cent ammonia would increase total emissions of PM2.5 and precursor gases by 167 per cent through both the shipping and combustion of the fuel, according to the Crea, which is based in Helsinki.
PM2.5 contributes to as many as 8 million premature deaths globally annually, and in Japan it leads to roughly 43,000 premature deaths a year, Crea said, citing data from State of Global Air, a website funded by the Clear Air Fund. Global premature deaths combined with non-fatal health illnesses caused by PM2.5, cost the world economy US$8 trillion , equivalent to 6.1 per cent of global gross domestic product, the authors said, citing World Bank data.
