Proposals to co-fire ammonia or hydrogen in power plants still leave 80-70% of fossil fuel emissions. Read more at straitstimes.com.
OAKLAND, California – Using ammonia and hydrogen alongside fossil fuels in power plants may result in more emissions than simply burning coal or gas, a new study has found, adding to scepticism over a decarbonisation technology being embraced by some Asian nations.
“This regional push to achieve large-scale co-combustion in fossil power plants threatens to drive vast ammonia and hydrogen production in exchange for minimal climate benefits at best,” Dr Seaver Wang, co-director of the climate and energy team at the Breakthrough Institute, an Oakland, California-based research group, said in a report released on Thursday.
The benefits shrink even further after considering the energy required to manufacture and transport ammonia and hydrogen.
