Ships powered by solid oxide fuel cells

Bloom Energy and Samsung Heavy Industries (SHI), a part of Samsung Group, today announced a collaboration to design and develop ships powered by Bloom Energy's solid oxide fuel cell technology. Bloom Energy is the world's leading provider of stationary fuel cells and SHI is one of the world's largest shipbuilding companies. For more information see the IDTechEx report on Electric and Hybrid Boats and Ships 2019-2029.
 
SHI aims to be the first shipbuilder to deliver a large cargo ship for ocean operation powered by fuel cells running on natural gas. Such an innovation will play a key role in helping the company exceed the 50 percent emissions reduction target, compared to 2008 levels, that the International Maritime Organization (IMO) has mandated all shipbuilders should achieve by 2050. The IMO, an arm of the United Nations, is the global standard-setting agency for the safety, security, and environmental performance of international shipping.
 
The two companies have already taken an important first step towards commercializing the maritime use of fuel cells for propulsion and auxiliary power. At a ceremony in the SHI Geoje shipyard, Samsung Heavy Industries announced they have received Approval in Principle from DNV GL, the internationally accredited marine shipping registrar and classification society, in collaboration with Bloom Energy to proceed with a fuel cell-powered ship design for Aframax crude oil tankers (COTs).
 
 
"As regulations to reduce GHG emissions take effect step-by-step, the introduction of fuel cells to vessels is inevitable. This approval, and being the first shipbuilder to secure this marine fuel cell technology, illustrates that Samsung Heavy is highly likely to lead the market," said Kyunghee Kim, vice president of SHI Outfitting Engineering Team.
 
"It is a meaningful GHG emissions reduction measure to apply Bloom Energy's fuel cell system to SHI's new Aframax design. SHI's new Aframax design is equipped with a new generating system in combination of the conventional, generator engines, and the new fuel cell technology, both fueled with LNG," said Hwa Lyong Lee, vice president of Regional Business Development, Maritime at DNV GL. "This innovative design is one of the ways to improve GHG emissions, to further make LNG a solid and long-term solution."
 
Today, 80 percent of the world's shipping fleet runs on heavy fuel oil, or bunker fuel. The combustion of this fuel to provide propulsion and auxiliary power to ships causes the marine transport industry to produce between 2% and 3% of global carbon emissions. If the global marine shipping industry was a country, it would be the sixth largest producer of greenhouse gas (GHG) emissions in the world.
 
Replacing combustion-based power generation from bunker oil with electrochemical conversion of liquid natural gas (LNG) through fuel cells could have a profound impact on carbon emissions from marine transportation. Bloom Energy and SHI estimate that replacing oil-based power generation on large cargo ships, which require up to 100 megawatts of power per ship, could reduce annual greenhouse gas emissions from shipping by 45 percent.
 
 
Combustion of bunker fuel also emits sulfur and particulate matter that causes respiratory illness. A 2018 study found that health impacts due to pollution from shipping include 14 million cases of childhood asthma annually and 400,000 premature deaths a year from lung cancer and cardiovascular disease. In contrast to bunker fuel combustion, Bloom Energy solid oxide fuel cells generate electric power through an electrochemical reaction, without combustion, that virtually eliminates particulate emissions, NOx, and SOx - an important consideration for the shipping industry.
 
Bloom Energy Servers use natural gas, biogas or hydrogen as fuel. Bloom Energy and SHI envision onboard fuel cells being powered by natural gas, converted from liquefied natural gas (LNG), which is already commonly transported by marine shipping worldwide.
 
The modularity of Bloom Energy Servers makes them well suited to the space constraints of ships. Unlike large, multi-megawatt generating combustion engines, Bloom Energy Servers can be deployed in increments as small as 200 kilowatts, enabling power sources to be distributed throughout a ship to optimize space utilization. SHI envisions Bloom Energy Servers displacing existing power generation sets, and therefore requiring no additional space, or even reducing the total space required for power generation.
 
Bloom Energy recently announced the capability of its fuel cells to run on hydrogen. As nations and ports develop their hydrogen infrastructure, fuel cell-powered ships could transition from natural gas fuel to hydrogen fuel and become zero-carbon and zero-smog emitters.
