Mitsubishi Shipbuilding Group Gains AiP for Low-Pressure LCO2 Carrier Design

admin — Tue, 15 Sep 2026 00:00:00 +0000

Six Japanese shipping and shipbuilding companies, including Mitsubishi Shipbuilding, obtained Approval in Principle from ClassNK for a standardized low-pressure 42,000m³ liquefied CO2 carrier under the MILES-based design framework. The AiP followed a HAZID risk assessment of LCO2 handling operations and a safety-focused design policy. The companies aim to support stable domestic construction and supply of LCO2 carriers as CCS projects begin in Japan, with the approval presented at Gastech 2026 in Bangkok.

Key facts

Chemicals	Liquefied CO2 (LCO2)
Capacity	42,000m³ class low-pressure LCO2 carrier
Location	Japan (CCS value chain); AiP presented in Bangkok, Thailand
Timing	2025-12-01, 2026-09-15
Partners	Kawasaki Kisen Kaisha, Ltd. ("K" LINE), Mitsui O.S.K. Lines, Ltd. (MOL), Nippon Yusen Kabushiki Kaisha (NYK Line), Nihon Shipyard Co., Ltd. (NSY), MILES Co., Ltd., Nippon Kaiji Kyokai (ClassNK)
End uses	CCS (carbon capture and storage) projects in Japan, LCO2 transport to storage sites

Market context

Liquefied carbon dioxide (LCO2) is CO2 cooled and pressurized into a dense liquid so it can be moved in bulk by ship. It is used mainly in carbon capture and storage (CCS), where captured CO2 from industrial sites is collected, transported and injected into geological formations for permanent storage. Demand for dedicated carriers therefore depends on how quickly CCS projects move from planning to operation, and in Japan that build-out is still in its early stages. Standardized vessel designs can shorten engineering time and make construction more repeatable for shipyards and owners. Low-pressure containment designs generally operate at colder temperatures than pressurized alternatives, which shapes tank materials, insulation and handling procedures. Approval in principle from a classification society is an early technical milestone rather than a construction contract, but it signals that a design has passed a structured hazard review. For chemical buyers and investors, the main read-across is to CCS logistics capacity and to shipping and shipbuilding suppliers serving this emerging niche.

MHIET Sets Hydrogen Co-Firing Specifications for KU Series Gas Engines

admin — Thu, 27 Aug 2026 00:00:00 +0000

Mitsubishi Heavy Industries Engine & Turbocharger (MHIET) has established hydrogen co-firing specifications for its KU Series gas engines, rated 3.65-5.75 MW and used in cogeneration systems, and has begun proposal activities. The specifications allow operators to switch from natural gas to any hydrogen co-firing ratio during operation, with design changes minimized so new units can start on natural gas and later convert. Existing KU Series engines can be retrofitted with minimal modifications, and the KU Diesel Engine (KU30A) can be converted via gas engine conversion.

Why it matters

Hydrogen-capable gas engines let distributed power and cogeneration users hedge fuel supply and extend existing assets, which may shift demand toward hydrogen, e-methane and co-firing-ready equipment.

Key facts

Companies	Mitsubishi Heavy Industries Engine & Turbocharger, Ltd. (MHIET), Mitsubishi Heavy Industries (MHI) Group
Chemicals	hydrogen, natural gas, e-methane (synthetic methane), CO2
Capacity	KU Series gas engine output 3.65-5.75 MW; hydrogen co-firing up to 50 vol% confirmed at rated output on a single-cylinder test engine for a 5.75 MW gas engine; GS6R2 engine 450 kW previously released with hydrogen co-firing specification
Location	Tokyo
Timing	2026-08-27
End uses	cogeneration systems, on-site power generation in institutions and factories, district heat supply, grid stability and power wheeling service, distributed power generation

Market context

Gas engines of this size are used in cogeneration, where one fuel input produces both electricity and useful heat for buildings, factories and district heating networks. Demand for such units comes from on-site power in institutions and industrial plants, distributed generation, and grid support services that need fast-responding capacity. Natural gas remains the dominant fuel for these engines, so any change that lets them burn hydrogen or synthetic methane affects both gas consumption and the outlook for low-carbon fuels. Hydrogen blended into natural gas is typically limited by engine design, materials and combustion stability, which is why co-firing ratios and retrofit paths matter to operators. Equipment that can run on a range of blends gives buyers flexibility to adjust fuel sourcing as hydrogen and e-methane supply develops, and it can slow the replacement of existing assets. For suppliers of hydrogen, e-methane and gas engine equipment, such developments signal where future offtake and component demand may build.
