Nuclear fusion technologies hold the potential to revolutionize the way we produce energy on earth. It is an opportunity to lift our current dependency on external factors such as weather and fossil reserves while producing vast amounts of emission free energy. For more than two generations, several novel ways to extract fusion energy have been proposed and attempted. One recently suggested approach is based on an assumed aggregate of deuterium named ultradense deuterium. The existence of this aggregate seems to follow from experimental observation of ejected fragments with relatively high kinetic energy. Uncertainties connected with the nature of the yet hypothetical ultra-dense state, call for further investigations as the present explanations are vague and third party verifications have so far not been completely independent. The focus of this study has been to investigate a possible aggreagate of hydrogen which could lead to the reported ejected particle energies. The present results provide an independent model analysis based on well known physics and aims to further enlighten the subject and eventually encourage continued studies. The nuclei are said to be metastable at a very small distance compared to a regular molecule, much like the exotic muonic molecule which is well known to catalyze fusion due to the small distance between the nuclei. In this thesis a one-dimensional numerical model has been created based on quantum chemistry to analyze the energetic stability of a proposed hydrogen aggregate. The results show that there may indeed exist a quasimolecular system where nuclei are stable at around 1/24 the distance of a regular hydrogen molecule. The nuclei must be axially aligned and of single charge to minimize repulsion, and also a certain minimum number of nuclei is required, found to be 17 in the model. The distance between the nuclei is an order of magnitude larger than observed in the muonic molecule, limiting though not removing the probability of fusion which decreases exponentially with increasing distance. The results point toward a need of further investigation through a threedimensional model of the state which would eliminate much of the uncertainty inherent in the current model.
