Golden Grain receives LCFS certification for cellulosic ethanol production
Golden Grain operates a corn ethanol plant in Mason City, Iowa, which has a capacity of 120 million gallons per year of ethanol. The facility was certified under CARB’s Low Carbon Fuel Standard (LCFS) programme on 5 August, with a carbon intensity (CI) rating of 29.09.
Edeniq’s Intellulose 2.0 technology has enabled the plant to achieve corn kernel fibre ethanol production up to, and sometime exceeding, 4% of total production. Two plants that have already received CARB certification using the same technology achieved average ethanol production of around 3% of the total.
Nine customers using Edeniq’s Intellulose technology have been approved by the US Environmental Protection Agency for D3 RIN generation and/or by CARB for low-CI corn kernel fibre ethanol production. Additionally, six current and existing customers are now using Intellulose 2.0, which builds on a previous version of the technology that measures the cellulosic ethanol produced from a single corn kernel component.
Intellulose 2.0 measure the amount of ethanol produced from multiple different molecules present in corn kernels, quantifying the individual contribution of each component.
