I’ve summarized several company news items below—apologies for any errors! 
Wärtsilä is retrofitting two RT‑flex main engines on Ulusoy Sealines’ bulk carriers to boost performance, fuel efficiency, and service life. By adding WPLO, ICC, and FAST technologies, the engines’ CII score will improve by 5 %, saving around 250 tonnes of fuel and cutting CO₂ emissions by roughly 780 tonnes per ship each year.
A new international regulation will require owners of large vessels to switch to lower‑carbon fuels after 2028 or face penalties of up to USD 380 per tonne of CO₂ emitted—driving demand for cleaner engine solutions.
Wärtsilä has unveiled a gas‑conversion upgrade for its 50DF multi‑fuel engine, converting it to run purely on gas and optimizing combustion. This reduces methane slip by up to 75 % and can cut fuel consumption by about 4.6 % under IMO’s E2 cycle.
Wärtsilä will supply a 64 MW/128 MWh energy‑storage system to Octopus Australia’s Fulham hybrid solar‑battery project. The DC‑coupled design minimizes conversion losses, and Wärtsilä’s GEMS controller optimizes power flow to support grid stability as renewables grow.
Wärtsilä Gas Solutions is building two large bioLNG plants in Finland that convert agricultural and food‑waste feedstocks into 25 tonnes of bioLNG per day. The projects include storage tanks and loading facilities, and produce an odorless biofertilizer that helps reduce dairy production’s carbon footprint.
In its latest strategy call, Wärtsilä confirmed that Energy Storage will remain a standalone segment focused on organic growth. The existing Energy segment will split into two independent reporting units, each with its own growth and profitability targets.
Wärtsilä has handed over the 100 MW Sodegaura power plant in Japan—featuring ten 34SG gas engines—to Tokyo Gas Engineering Solutions. These fast‑start engines will help Japan reach its 40–50 % renewable‑energy goal by 2040 and participate in the new capacity market.
At Brazil’s Suape II plant, Wärtsilä is running the world’s first large‑scale test of an ethanol‑fueled 32M engine. The pilot aims for up to 4 000 test hours as part of the WISE program, paving the way for broader use of ethanol in renewable energy.
