We work toward a future with 100% clean energy

We work toward a future with 100% clean energy. Currently, the world is dependent on carbon-based baseload energy. That is why our goal is to construct and deploy 1 000 SMRs. Together they will produce close to 500 TWh clean electricity annually. If successful, we will avoid 0.5 gigatons of C02 - or 1% of global emissions - every year.

Our lead-cooled fast reactors (LFRs) will be used for electricity, heating, and industrial applications such as production of hydrogen, HVO, syngas, and biochar. By targeting otherwise hard-to-abate sectors we contribute to decarbonization throughout the industrial value chain.

Our History

SEALER-55 is Blykalla's commercial SMR units, which will have an output of 55MW each. These will be used for both industrial processes and electricity production. Due to their modular structure they can be produced in factories and shipped to their final locations. The compact design avoids ultra heavy forging, which significantly shortens production time and cost.

We expect to start serial production of SEALER-55s in the early 2030's. Our goal is to produce 1,000 of these units - which would remove 1% of global emissions annually.

Accelerating the industry

Blykalla is at the forefront of Sweden’s nuclear energy future, bringing together key stakeholders, including policymakers, industry leaders, and technical experts, to drive discussions on the role of advanced nuclear power in a sustainable energy system. As the host of industry-wide events, we create platforms for collaboration and progress in nuclear innovation.

In February 2025, we hosted a groundbreaking event to mark the beginning of our testing facility at the at the OKG nuclear power plant in Oskarshamn, Sweden, together with Sweden’s Deputy Prime Minister and Minister for Business, Energy, and Industry Ebba Busch.
