Kawasaki Heavy Industries (KHI) and Corvus Energy have reached a licensing agreement for a lithium-ion capacitor (LiC) technology for the offshore market.
“Corvus Energy has been an outstanding development partner for the LiC technology,” said Takeshi Ohata, managing executive officer of Kawasaki Heavy Industries at their headquarters in Tokyo, Japan. “Their battery engineering experience and marine market leadership gives Corvus Energy expertise unlike any other. Their know-how around thermal management inside battery modules is critical to ensuring safe and reliable operation.”
The LiC incorporates lithium-ion capacitor cells into an energy storage system (ESS) with high-efficiency liquid cooling that maintains an optimal temperature range at very high RMS currents and charge/discharge rates, the company said. The LiC will safely sustain charge/discharge rates of 600oº C peak and 300oº C continuous, enabling both energy recapture/storage and fast discharge for high-power load handling.
“It is truly a validation of our world-class R&D capabilities that KHI selected Corvus to develop this technology,” said Sean Puchalski, EVP of Strategy & Business Planning for Corvus Energy. “The new cutting-edge LiC technology provides the best of both worlds — current-handling performance nearing a supercapacitor with improved energy density. It will enable our offshore customers to cost-effectively improve efficiency through energy recapture from heave compensation, drilling draw works and payload lowering applications with a lightweight, space-saving footprint.”
Corvus Energy will introduce a new product based on the LiC ESS technology with Kawasaki Heavy Industries, trademarked Blue Marlin and targeting the offshore segment it currently serves with its Orca and Dolphin ESSs and Moray subsea ESS. The new Blue Marlin product is expected to be available in 2020.
“Corvus offers a timely solution to an urgent problem,” said Geir Bjørkeli, CEO of Corvus Energy. “Offshore producers are increasingly committed to investing in solutions that reduce the carbon footprint of their operations. We are thrilled that the progressive leadership at Corvus shareholders Equinor and Shell—whose offshore operations are the largest in the world—will help speed adoption of Corvus’ energy efficiency solutions in the offshore segment.”
