Korean Shipbuilders work on eco-friendly ships

Hyundai Heavy Industries Co. and other major shipbuilders are working to improve ships' environmentally friendly power systems to win further deals despite stricter pollution regulations.

The International Maritime Organization ( IMO) has taken mandatory steps requiring carriers to run a fleet of vessels built to reduce pollution by more than 30 per cent by 2025 compared to 2008.

The IMO also aims to further reduce emissions by 40 per cent by 2030 and by 70 per cent by 2050.

The IMO lowered the sulfur limit on fuel content from 3.5 per cent to 0.5 per cent from 1 January 2020.

In the atmosphere, sulfur oxides can lead to acid rain which hurts crops and forests and causes ocean acidification.

In March in Ulsan, 414 kilometers southeast of Seoul, Hyundai Heavy Industries and its holding company Korea Shipbuilding & Offshore Engineering Co. set up a center to construct ships powered by both liquefied natural gas ( LNG) engines and fuel cells by the late 2021.

In March 2019 Hyundai Heavy received the green light from DNV-GL, a Norwegian-German quality assurance and risk management firm, for the design of a crude carrier with the LNG-fuel cell-propelled engine system.

DNV-GL approval allows Hyundai Heavy to accept an order from purchasers for the ship with the device.

Samsung Heavy has signed an agreement with Bloom Energy and for the first time in the world has marketed solid oxide fuel cells (SOFCs). SOFCs are power conversion devices which produce electricity.

Push for eco-friendly ships by Hyundai Heavy has been trailed in by its smaller rival Samsung Heavy Industries Co. and Daewoo Shipbuilding & Marine Engineering Co.

Another leading shipbuilder, Daewoo Shipbuilding, has begun designing a lithium-ion energy storage system, another environmentally sustainable ship power source.

Daewoo Shipbuilding signed an agreement with armored vehicle manufacturer Hanwha Defense in February to improve the lithium-ion energy storage system that helps minimize greenhouse gas emissions and save ship fuel.
