Leading electrified powertrain for Class 8 semi-trucks provider Hyliion Holdings has entered into a definitive agreement to acquire a new hydrogen and fuel agnostic capable generator KARNO from GE Additive. The KARNO generator emerged out of GE’s long-running R&D investments in metal additive manufacturing across multiple industries and in areas such as generator thermal and performance design. Initial testing indicates the KARNO generator is expected to comply with all current and foreseeable emissions standards, specifically from CARB and EPA, even when utilizing conventional fuels.The technology is expected to achieve a 20%+ efficiency improvement over today’s conventional generators and could be more efficient than most available fuel cells. These efficiency improvements should, in turn, enable fuel cost reductions and improved vehicle range. The technology should also provide for significant reductions in noise, vibration, moving parts and maintenance as compared to current combustion engines.The KARNO power system will be capable of operating on over 20 different fuels including hydrogen, natural gas, propane, ammonia and conventional fuels. The technology uses heat to drive a sealed linear generator to produce electricity. The heat is produced by reacting fuels through flameless oxidation or other heat sources including renewables.In late 2023, Hyliion plans to first release the Hypertruck ERX powertrain, which leverages a natural gas engine as the generator onboard. In the years following, Hyliion plans to release the Hypertruck KARNO, its fuel agnostic variant, as phase two in the Hyliion journey to a hydrogen-based future. Hyliion will also explore other adjacent markets to leverage this technology for cost savings and emissions reductions.The Hypertruck is an electric powertrain that is recharged by an onboard generator for Class 8 commercial trucks that aims to provide lower operating costs, emissions reductions, and superior performance. The initial product variant to come to market is the Hypertruck ERXTM which leverages an onboard natural gas engine as the generator. The Hypertruck Fuel Agnostic will leverage the KARNO fuel agnostic generator to produce electricity. Hyliion also plans to release a Hypertruck Fuel Cell, which will only operate on hydrogen.
