Hyliko trucks do not emit exhaust or particulate emissions from brake wear. The only emission: a small amount of water.
Yes, carbon-negative energy is possible. Biomass thermolysis, the process that produces Hyliko hydrogen, is a veritable carbon trap that transforms waste from wood industry into biochar: an organic charcoal fertilizer used for agriculture… all while producing hydrogen.
Carbon is first captured from the air by plants for growth. Once the carbon is fully trapped in the soil, it acts as a soil amendment, creating a new positive cycle. This is how carbon-negative hydrogen is produced!
