Hanwha Solutions joined Shell’s efforts to build extensive H₂ refueling infrastructure in California. By supplying Shell with high-pressure H₂ tanks for transport within its network of stations, Hanwha will help accelerate California’s energy transition and decarbonizing efforts.

Hanwha Solutions’ H₂ tank manufacturing subsidiary, Hanwha Cimarron, said it finalized a purchase order with Shell to provide its Neptune tanks, which are Type IV high-pressure H₂ tanks. The carbon fiber-reinforced, 2,000-liter capacity vessels can store H₂ at a pressure of 517 bar — the highest-pressure level among Type IV tanks.

Another strength of the Neptune tanks is their anti-buckling technology, which allows the H₂ inside to be fully extracted without any internal damage to the tank. Typically, Type IV high-pressure tanks must reserve 10% of their total contents to prevent tank shrinking during storage, which reduces their transport efficiency. However, Neptune tanks have proven their stability, receiving certificates from the U.S. Department of Transportation for transportation efficiency and the American Society of Mechanical Engineers for storage usage.

Hanwha Cimarron’s supply of H₂ tanks will support Shell’s efforts to extend its H₂ refueling network across California. The state is emerging as a key H₂ hub in the U.S., operating 52 of the country’s total 66 refueling stations. According to research firm MarketsandMarkets, the global H₂ energy storage market is projected to reach $119.2 B by 2027 and North America will constitute about 13% of the global market volume.

“This supply contract is a great foundation for our collaboration with Shell and our efforts to expand our presence in the U.S. hydrogen market,” said Du-hyoung Ryoo, head of Hanwha Solutions’ Advanced Materials Division. “We are also expanding the company’s hydrogen tank business in Europe, including Germany, to attract more clients globally.”

Acquired by Hanwha Solutions in December 2020, Hanwha Cimarron, formerly known as Cimarron Composites, founded by NASA scientist Tom Delay, is seeking to scale up its business. Its $51-MM investment plan to build a high-pressure tank manufacturing facility in Opelika, Alabama in the U.S. is well underway. When construction is completed later this year, the Opelika factory will be able to produce up to 4,000 high-pressure tanks annually.

In 2021, Hanwha Cimmaron signed a deal with Texas-based energy company Sunbridge Energy Services to provide storage tanks for compressed natural gas (CNG). The $260-MM deal aims to deliver tube trailers containing dozens of vessels that can store CNG and other pressurized gases such as H₂.
