Marine battery producer AYK Power has signed a second take care of Spanish ship proprietor Mureloil to provide diesel electrical hybrid methods.
AYK will ship the identical 4.2 MWh Aries+ battery system to Mureloil’s 8000 DWT product tanker Bahía Beatriz as its sister vessel the Bahía Candela, additionally a 8000 DWT tanker.
Bahía Beatriz is at present beneath development on the Astilleros de Murueta shipyard, exterior Bilbao. AYK’s Spanish agent VULKAN will assist set up the battery system. The 2 vessels can function on full electrical energy throughout port operations.
The battery system will use lithium iron phosphate (LFP) expertise, which AYK stated can outperform nickel manganese cobalt (NMC) batteries.
“NMC has been probably the most generally used battery chemistry due to its supposed better density, however its chemistry is understood to be way more harmful than LFP,” stated AYK Power founder Chris Kruger. “AYK is displaying that LFP can outperform NMC and ship better vitality density, larger security and higher worth.”
The vessels will double Mureloil’s capability to move biofuels and methanol, strengthening the delivery line’s presence within the sustainable marine fuels sector.
Demand for battery energy is additional being fueled by mounting regulatory strain on ship house owners, who face better scrutiny and penalties beneath new legal guidelines like FuelEU and the EU Emissions Buying and selling System.
“The regulatory squeeze is actual,” Kruger stated. “With the brand new sustainability reporting necessities, ship operators know they want reasonably priced carbon slicing options like marine batteries that ship.”
In June 2025, AYK’s newest vary of marine batteries, together with Pisces, Pisces +, OrionAN, OrionAN+ in addition to aluminum variations of AYK legacy modules, obtained kind approval from the classification society DNV.
The contract with Mureloil follows a deal to provide Spanish ferry operator Baleària with two electrical catamaran ferries to function between Tarifa within the south of Spain and Tangier, Morocco.
“The time for marine batteries has come,” Kruger stated. “Though these vessels are hybrid diesel electrical we at the moment are seeing that the expertise is there to go absolutely electrical not simply on ferries, OSVs and workboats but additionally tankers like these. However seeing batteries on tankers is a major second for electrical energy. The vitality density of batteries is growing, the value is lowering and the payback interval is faster.”
