Finland-based Neste has submitted three new Tier 2 Pathways for California’s Low Carbon Gas Customary (LCFS) for renewable diesel produced at its Porvoo, Finland refinery. Two pathways are for Renewable Diesel from Tallow & Animal Fats and one is for Renewable Diesel from Used Cooking Oil (UCO).
Neste already has eight LCFS pathways for renewable diesel produced from a wide range of feedstocks (tallow, Australian tallow, North American tallow, SE Asian fish oil, New Zealand tallow, North American corn oil, world used cooking oil and Asian used cooking oil) at its main Singapore facility (earlier publish), with carbon intensities (CI) starting from 16.89 to 39.06 gCO2e/MJ.
The Porvoo renewable diesel (RD) plant makes use of blended feedstocks to supply RD, naphtha, and a propane-rich off-gas. The RD produced is branded and marketed as Neste My Renewable Diesel. The manufacturing plant is built-in into the Neste Porvoo refinery’s current industrial infrastructure which incorporates hydrogen manufacturing, stream and energy in addition to waste water remedy, port and storage providers.
The method steps on the Porvoo manufacturing plant embrace pre-treatment, hydro-treatment, stabilization, and recycle. Since Neste makes use of ocean tanker vessels (cargo capacities not included within the CA-GREET2.zero mannequin) used to move feedstock, Neste utilized for a Tier 2 Technique 2B RD pathway utilizing globally sourced tallow as feedstock.
In session and steerage from Argonne Nationwide Laboratory, CARB workers utilized GaBi (Life Cycle Information software program) to calculate emission components for the ocean tankers reported by Neste of their pathway software.
The 2 tallow functions have CIs of 45.08 and 51.90 gCO2e/MJ; the tallow feedstock for the RD with the upper CI first makes an intermediate cease at a pretreatment facility.
The Porvoo pathway for RD from UCO carries a CI of 30.97 gCO2e/MJ.
