PowerX, Inc. on Thursday (25 May) unveiled the detailed design of the first-ever ‘Battery Tanker’ at the ‘Bariship’ International Maritime Exhibition held in Imabari City, Ehime Prefecture, Japan. 

The inaugural ship “X” aims for completion by 2025, with domestic and international field testing planned to commence in 2026.

A new company named Ocean Power Grid Inc. will be established in the third quarter of 2023 to advance the maritime power transmission business utilising Battery Tankers. This company will be responsible for owning, selling, and operating the battery tankers both in Japan and abroad. 

PowerX has also signed a Memorandum of Understanding (MoU) and a partnership agreement with Kyushu Electric Power Co., Ltd. and the City of Yokohama to pursue the novel concept of maritime power transmission and achieving carbon-neutral ports.

The first Battery Tanker “X” is scheduled for domestic and international field testing starting in 2026. The electric propulsion vessel boasts a length of 140 metres and will be equipped with 96 containerised marine batteries, providing a total capacity of 241MWh.

The onboard battery system is based on the firm’s proprietary module design, featuring safe and reliable lithium iron phosphate (LFP) battery cells that ensure a lifespan over 6,000 cycles. Additionally, the battery system is highly scalable, allowing for the installation of additional batteries to create larger electric transport vessels such as Power Ark 1000 or even larger sizes to meet specific mission requirements. 

The system includes dedicated gas emission control and fire suppression mechanisms to ensure safety. Real-time monitoring of the battery system, charging controllers, and power conversion systems further enhances safety measures. 

All batteries will be manufactured in-house in Okayama Prefecture and are scheduled to obtain international ship classification certifications and applicable standards such as DNV and Class NK, undergoing rigorous testing to meet the strictest conditions. Delivery of the batteries is scheduled to commence by mid-2024.

The Role of Battery Tankers

With its onboard battery systems, Battery Tankers can be leveraged to store and transport surplus electricity generated from renewable sources. Decommissioned or idle thermal power plants located near ports can be retrofitted into charge/discharge points for the Battery Tankers, where the power is transmitted to users via grid connections on the land, enabling further effective use of renewable energy.

Moreover, areas with high potential for renewable energy generation are often distant from urban areas and other regions with high power demand. Strengthening transmission infrastructure becomes essential in such cases. 

Given the current energy density of lithium-ion battery cells, the Battery Tanker is an optimal solution for short-distance maritime power transmission from land to land, complementing existing inter-regional grid transmission lines. For instance, in Japan, a Battery Tanker can carry power from regions with high renewable energy supply potential, such as Kyushu and Hokkaido, to high-demand areas of Honshu or for inter-island power transmission.

PIL's LNG dual-fuel boxship “Kota Elok” arrives in Singapore on maiden call

Singapore-based Pacific International Lines Pte Ltd on Monday (20 July) said its first 13,000 TEU LNG dual-fuel container vessel, Kota Elok, recently made her maiden call to Singapore on 15 July.

As the first of 13 new 13,000 TEU vessels joining its fleet, Kota Elok is equipped to operate on liquefied natural gas (LNG) and low-sulphur fuel oil that helps reduce our greenhouse gas emissions. 

The vessel also incorporated energy-saving features and digital technologies to reduce fuel consumption and enhance operational performance, as well as a bow windshield to improve aerodynamics, contributing to improved fuel efficiency and lower emissions over the course of long-haul voyages.

“Following Singapore, Kota Elok will continue her voyage on our East Coast Service 1 (ES1) route to South America, calling at ports in Brazil, Uruguay, and Argentina before returning to Asia,” the company said in a social media post. 

Kota Elok also became PIL’s first vessel to receive Lloyd’s Register certification for compliance with the IACS UR E26 and UR E27 cyber security requirements.

Developed by the International Association of Classification Societies (IACS), UR E26 and UR E27 are mandatory cyber resilience requirements for newbuild vessels contracted from 1 July 2024.

CIMC SOE secures order for 12,000-cbm LNG bunkering vessel from Sinopec Clean Energy

China’s Nantong CIMC Sinopacific Offshore & Engineering Co., Ltd. (CIMC SOE) recently signed a contract with Sinopec (Beijing) Clean Energy Co., Ltd. to build a 12,000-cubic metre (m3) LNG bunkering vessel, according to Chinese maritime media.

The vessel is scheduled for delivery in 2028 and will support Sinopec’s efforts to expand its presence in the marine clean energy sector.

Once operational, the vessel is expected to strengthen Sinopec’s domestic coastal LNG bunkering network and help address gaps in China’s LNG bunkering infrastructure.

With this signing , CIMC Pacific Offshore Engineering’s LNG bunkering vessel orderbook is further strengthened, maintaining its leading position in the global market for small and medium-sized LNG bunkering vessels.

The contract also marked another milestone for CIMC SOE, which has seen a sharp increase in orders and business performance this year amid a surge in domestic LNG vessel demand.

ABS awards AiP to Korean institute for SMR-powered container ship concept design

Korea Research Institute of Ships & Ocean Engineering (KRISO) on Thursday (16 July) received Approval in Principle (AiP) from the American Bureau of Shipping (ABS) for its concept design of a 15,000 TEU Small Modular Reactor (SMR)-powered container ship utilising Molten Salt Reactor (MSR) technology.

KRISO said the AiP recognises the technical feasibility and safety of its concept design, marking an important milestone toward the development of next-generation nuclear-powered commercial ships.

“This achievement demonstrates international recognition of KRISO’s technological capabilities in the rapidly evolving field of nuclear-powered shipping, supporting the transition toward low-carbon maritime transport,” it said. 

Building on this milestone, KRISO will continue advancing basic and detailed ship design, paving the way for future demonstration and commercialisation of SMR-powered vessels. 

Through continued R&D and international collaboration, KRISO remains committed to strengthening next-generation maritime technologies and contributing to the safe deployment of nuclear propulsion in the maritime industry.
