Boson Energy, a Luxembourg cleantech company founded in 2008, develops solutions for clean, efficient, and affordable production of circular carbon-negative hydrogen from non-recyclable waste and biomass. They aim to create local, sustainable, and profitable ecosystems running on renewable hydrogen.
Challenges: biomass gasification
Hydrogen (H₂) is a “simple solution” to address the world's energy problems and needs. The overall thermal efficiency of converting hydrogen to electric energy required by a fuel cell electric vehicle (FCEV) is three times greater than the thermal efficiency of burning this liquid fuel to power today's internal combustion engine vehicles. Utilizing hydrogen in this manner may significantly contribute to global energy security.
Hydrogen must be separated from hydrocarbons (e.g., methane CH₄) or water (H₂O). The majority of the world's hydrogen (over 60 million tons) is currently produced via steam methane reforming (SMR) process, which requires a significant amount of energy input and emits a substantial amount of carbon dioxide (CO₂). The SMR process emits between 5 and 9 tons of CO₂ per ton of hydrogen produced.
Boson Energy Technology
Boson Energy has developed an efficient biomass gasification system that generates hydrogen-rich syngas through the use of a high-temperature gasifying agent and the chemical reaction between calcined lime (CaO) and CO₂.
