TSE:6016
Japan Engine Corporation's 6UEC35LSGH hit a hydrogen co-firing ratio above 95% and cut emissions by the same margin against heavy-oil engines in factory tests witnessed by ClassNK, but the engine still has to survive installation on a Mitsui O.S.K. Lines vessel and at-sea demonstration testing from April 2028 before it counts as proven.
Japan Engine Corporation's 6UEC35LSGH cut emissions by 95% or more against a heavy-fuel-oil engine in factory trials, but the real test, an April 2028 sea demonstration aboard a Mitsui O.S.K. Lines vessel, is still nearly two years off.
A four-entity joint filing reports 644,000 shares, or 7.67% of the company, after what the cover page calls a significant contract change. The disclosures describe stock borrowing, lending and prime-brokerage arrangements, so the market signal is a meaningful reported position, not a declared strategic campaign.
