Baker Hughes and Hanwha in ammonia gas turbine agreement

Ammonia-fueling is widely seen as key to shipping’s decarbonization. And while ammonia fueled four stroke engines will soon be a reality, ammonia gas turbines could be in the not too distant future.

Korea’s Hanwha Group plans to complete the development of LNG carriers and containerships using an ammonia gas turbine propulsion system by 2028.

The ammonia gas turbines will be developed in cooperation with Baker Hughes (NASDAQ: BKR) under a joint development and collaboration agreement just signed...

Op-Ed: Cutting fuel costs at the source

By Per Funch-Nielsen, Director, AuctionConnect

The pathway for decarbonization in the shipping industry has been laid out by the IMO, providing clear objectives and checkpoints along the way. The global industry regulator has set a goal of net zero-emissions from ships for around 2050. Indicative assessments of progress require the industry to achieve at least a 20% reduction in emissions compared to 2008 levels and striving for 30%, and a 70% reduction against 2008 levels by 2040, striving for...
