ABB and Blykalla Expand Partnership to Advance Maritime Nuclear Propulsion Solutions

In October 2024, Blykalla and ABB solidified their partnership by signing a memorandum of understanding (MOU) aimed at harnessing ABB’s automation, electrification, and digitalization solutions to support the development of Blykalla’s small modular reactor (SMR) prototype, known as Sealer E. This innovative reactor features an electric lead-cooled design and incorporates robust cybersecurity frameworks to align with stringent nuclear safety regulations.

This new MOU builds upon an existing agreement, reflecting a growing momentum within the nuclear energy sector, particularly as it pertains to marine applications. Blykalla's leadership has recognized ABB’s expertise in system integration, power distribution, control, and automation technologies as critical to the successful deployment of the SMR as a viable shipboard solution.

Jacob Stedman, CEO of Blykalla, expressed optimism about extending the partnership into this strategically significant vertical. He noted that the compact design of their reactor presents a unique opportunity to pioneer maritime nuclear propulsion, a solution aligning with the industry's demand for clean energy. However, realizing this ambitious vision will necessitate a committed ecosystem of partners, and this collaboration is viewed as a foundational element.

Juha Koskela, President of ABB’s Marine and Ports Division, emphasized the substantial potential of SMRs to facilitate decarbonization efforts. He stated that the collaboration with Blykalla would be instrumental in advancing the viability of these reactors for maritime applications. The next generation of SMRs promises innovative ship designs that can significantly reduce emissions compared to traditional carbon-based fuel systems.

Founded in 2013 and formerly known as LeadCold, Blykalla emerged from the KTH Royal Institute of Technology in Stockholm, where lead-cooled reactor systems have been under development since 1996. Blykalla is progressing with its Sealer Swedish Advanced Lead Reactor, with plans for a demonstration reactor, Sealer D, expected to have a thermal output of 80 MW. The company aims to have its first commercial reactor, the 140 MW Sealer 55, operational by the early 2030s.

Blykalla's Sealer reactor is one of three selected for further evaluation in Norway's NUPROSHIP project, which focuses on nuclear propulsion for merchant ships. This initiative assesses Generation IV SMR technologies for their feasibility in commercial shipping, particularly for larger vessels. The overarching goal of the research program is to develop a commercially viable zero-emission technology for deep-sea shipping that meets stakeholder needs and operates without subsidies post-development.
