Bunker Saving Waste Heat Recovery System Gains Class Approval
Calnetix Technologies, LLC. (Calnetix) Tuesday announced at the Nor-Shipping conference that its bunker saving Hydrocurrent waste heat recovery system has gained class approval from Lloyd's Register and Nippon Kaiji Kyokai (ClassNK).
The technology can save up to 200 tonnes of bunker fuel annually, and reducing carbon monoxide emissions by an estimated 18 tonnes per year, according to Calnetix.
Developed by Calnetix in partnership with Mitsubishi Heavy Industries Marine Machinery and Engine Company (MHI-MME), the Hydrocurrent uses an Organic Rankine Cycle (ORC) heat recovery process and coverts heat from engine-jacket water into electricity.
"These approvals from two highly respected classification societies are a major stepping stone toward full commercialisation of the Hydrocurrent product in the maritime industry," said Vatche Artinian, CEO at Calnetix.
The system is also said to be unique in its ability to draw usable heat from sources with temperatures as low as 80⁰C, yet still leaving enough heat in the jacket water for use by fresh-water desalinators.
"At Calnetix, we have extensive experience in ORC heat recovery for other industrial applications," said Artinian.
"Over the last five years, we have deployed over 35 MW of capacity in land-based installations around the world.
"Now we're bringing that proven technology to the maritime industry for the first time," added Artinian.
In April Calnetix announced that the Hydrocurrent system had won an award at the 2015 Marine Propulsion Conference in London.
The use of waste heat recovery systems is not new to the maritime industry, and in May it was announced that six United Arab Shipping Company's (UASC's) newbuilds are to incorporate the energy saving technology.
