The Energy Talk - Storytellers of Africa's Energy Transition
Founders in Focus: Nimbus Aerospace
Olu sat down with Adrian Groos (CEO) and Akeem Niyonzima (CTO), co-founders of Nimbus Aerospace, an aerospace company building a six-passenger hybrid-electric light jet. At the time of recording, Nimbus Aerospace had grown after successful entry into Techstars and was also raising a VC-led round. Additionally, Nimbus Aerospace plans to sell their aircrafts at around $12.5M (vs the ~$12M light jet market leader), to lower CAPEX costs for consumers while expanding options. As Adrian notes, Nimbus Aerospace went hybrid-electric to reduce consumers’ OPEX costs and carbon emissions. Hybrid jets’ comparative edge over standalone propulsion systems such as gas-, hydrogen-, and electric-powered jets enables both outcomes for various reasons. For one, compared to full electric (battery energy density/weight limitations) or hydrogen (infrastructure and cost hurdles), hybrid-electric uses already-available technology, cutting fuel use by ~50% and lowering maintenance costs (electric engines cost ~80% less than jet engines), while remaining compatible with existing infrastructure. Adrian also discloses the exact findings informing Nimbus Aerospace’s decision to manufacture six-passenger light jets. Light jets make up ~36.5% of the U.S. private jet market and service ~80% of private jet trips, making it an attractive segment for a new entrant. On engineering progress, Akim shared that the team is currently flight testing a quarter-scale, fully electric prototype — deliberately not yet incorporating the hybrid propulsion system — to first nail down the aerodynamics and design data needed before integrating the hybrid powertrain into the full-scale aircraft. As he disclosed, the build was the fastest turnaround of any prototype worked on thus far; further, Nimbus Aerospace aims to leverage already-established manufacturing processes to hasten certification timelines. Additionally, Akim revealed that safety remains his number one filter on every decision, from flight testing to design changes. Akim then spoke candidly about representation in the industry, noting that he and Adrian are regularly approached by people — including women — who prior to their conversation did not realize people from diverse ethnic backgrounds could start a company like Nimbus Aerospace, underscoring why diverse leadership matters for driving innovation in aviation and aerospace.
