The pressure to accelerate just transitions to Net Zero is felt across all disciplines. Moreover, researchers face challenges of developing research aims directed at wicked problems that arise in engineering transitions. Engineering research groups in particular face the challenge of incumbency, following their vested disciplinary inquiries when the just transition challenges are transdisciplinary and require new perspectives. Recent research in transition engineering has developed a transdisciplinary process to navigate a solution space that includes long term sustainability goals, social good outcomes and viable technological enterprises. This paper reports the experience and results of the Transition Engineering Sprint process undertaken by the Engineering and Physical Sciences Research Council (EPSRC) funded Decarbonisation Pathways for Cooling and Heating (DISPATCH) project research group to reframe research questions around the just transition issue of fuel poverty. A Transition Engineering Sprint is a methodology using a series of whole-systems explorations which creates a new narrative around wicked problems and unveils a creative space exploring direct routes to transitions. The sprint team included PhD students and Post Docs in energy, power system and transition engineering, along with data and social scientists. The process resulted in uncovering a root cause for fuel poverty and generating exploratory concepts for research in a sandbox. The new concepts re-framed ongoing research activities in the group and opened novel transdisciplinary research agendas. The results of a critical self-reflection exercise show that the Transition Engineering Sprint proved effective and that it can be applied in similar trandisciplinary engineering research contexts.
