HB11 Energy – founded in 2017 and based in Sydney, Australia – is developing commercial fusion energy technology that uses laser-ignited hydrogen-boron (pB11) fuel. The company’s approach leverages high-intensity laser systems to initiate fusion between hydrogen and boron-11, which, if realised at scale, is intended to produce clean, base-load electrical energy with low levels of neutron production.

HB11’s work builds on experimental and theoretical research into the hydrogen-boron fusion reaction and its potential to be driven using fast-ignition laser techniques. The company has reported results from petawatt-class laser experiments that demonstrate fusion reactions and alpha particle generation using its boron fuel targets, and it continues to refine target design and laser coupling for improved performance.

HB11 collaborates with research institutions around the world to advance its technology, including laser facilities and high-power research partners in Europe and Japan, as well as national science organisations. These partnerships support joint experiments, high-power laser access, target development and simulation work as part of its fusion development programme.
