The first PowerX Power Ark battery tanker is scheduled to start out area testing beginning in 2026
PowerX, the Japanese battery startup that first introduced plans for a ship-based different to subseas cables again in August 2021, has now launched extra particulars on its Power Ark 100 battery tanker.
Unveiled on the Bariship International Maritime Exhibition held in Imabari City, Ehime Prefecture, Japan, the primary battery tanker is scheduled for home and worldwide area testing beginning in 2026. The electrically propelled vessel will likely be 140 meters lengthy and will likely be outfitted with 96 containerized marine batteries, offering a complete capability of 241 MWh.

The onboard battery system is predicated on PowerX’s proprietary module design, that includes lithium iron phosphate (LFP) battery cells designed to have a lifespan of over 6,000 cycles. Additionally, the battery system is very scalable, permitting for the set up of extra batteries to create bigger electrical transport vessels reminiscent of Power Ark 1000 and even bigger sizes to satisfy particular mission necessities. The system contains devoted fuel emission management and hearth suppression mechanisms to make sure security. Real-time monitoring of the battery system, charging controllers, and energy conversion techniques enhances these security measures.
All batteries will likely be manufactured in-house in Okayama Prefecture and are scheduled to acquire worldwide ship classification certifications and meet relevant requirements, reminiscent of these set by DNV and Class NK, present process rigorous testing.
Delivery of the batteries is scheduled to start out by mid-2024.
ROLE OF BATTERY TANKERS
A brand new firm, Ocean Power Grid Inc., will likely be established within the third quarter of 2023 that may personal, promote, and function the battery tankers in Japan and overseas. PowerX is searching for enterprise companions worldwide for this new know-how and enterprise endeavor.
PowerX has signed a memorandum of understanding and a partnership settlement with Kyushu Electric Power Co., Ltd. and the City of Yokohama to pursue the brand new maritime energy transmission idea and obtain carbon-neutral ports.
Their onboard battery techniques permit battery tankers to retailer and transport surplus electrical energy generated from renewable sources. Decommissioned or idle thermal energy crops situated close to ports might be retrofitted into cost/discharge factors for the Battery Tankers, the place the facility is transmitted to customers by way of grid connections on the land, enabling additional efficient use of renewable vitality.
PowerX says that areas with excessive potential for renewable vitality technology are sometimes distant from city areas and areas with excessive energy demand. It says that, given the present vitality density of lithium-ion battery cells, the battery tanker is an optimum resolution for short-distance maritime energy transmission from land to land, complementing present inter-regional grid transmission traces. In Japan, for instance, a battery tanker may carry energy from areas with excessive renewable vitality provide potential, reminiscent of Kyushu and Hokkaido, to high-demand areas of Honshu or for inter-island energy transmission.
As the vitality density of batteries improves and their value decreases, it’s anticipated that longer-distance maritime transmission from offshore wind energy crops to the land will develop into possible. Battery tankers supply a sensible resolution, particularly in Japan, which is liable to earthquakes and has deep-sea environment. The ship-based resolution resolves points reminiscent of prolonged downtime from undersea cable malfunctions and repairs and the excessive prices related to ultra-high voltage connections and substations. As a consequence, says PowerX, the battery tankers will allow the set up of offshore wind farms in areas the place undersea cable deployment presents challenges.
