Baker Hughes CCS study confirms feasibility of CO2 storage at Aemetis
A new CCS study by Baker Huges, commissioned by US-headed renewable natural gas and renewable fuels company Aemetis, Inc, has concluded that more than 2 million tonnes per year of carbon dioxide (CO2) can be removed from the atmosphere and injected safely into the earth at the Aemetis Keyes and Riverbank ethanol plant sites in California (CA).
The Carbon Capture and Sequestration (CCS) geologic formation review and drilling study was completed by Aemetis Carbon Capture, a subsidiary of Aemetis, and was conducted by Baker Hughes, a global energy services company with operations in 120 countries.
The Baker Hughes study estimated that 1.0 million tonnes per year of CO2 can be sequestered in the saline formations located deep underground at or near the Aemetis Keyes ethanol plant site. The study noted that up to 1.4 million tonnes per year of CO2 should be injectable at or near the Aemetis Riverbank site due to the favorable permeability of the saline formation and other factors.
The conclusions from the initial Baker Hughes geologic formation and pre-drilling study confirm the feasibility of Aemetis plans to construct two CO2 injections wells at or near the Aemetis biofuels sites. We have completed Front End Loading engineering and are now working on the Front End Engineering Design (FEED) and permitting for the Aemetis CCS projects, said Brian Fojtasek of ATSI, Project Manager for the Aemetis Carbon Capture construction phase.
Once complete, the Aemetis Carbon Capture CCS project is expected to capture and sequester more than 2 million tonnes of CO2 annually at the two Aemetis biofuels plant sites in Keyes and Riverbank, California (CA).
This latest study for Aemetis builds on our deep experience in providing storage site evaluation, well placement, underground formation review, and drilling technology for CCS injection projects. This is another step in the development of CCS capacity, which will be a key part of the energy transition going forward, said Ajit Menon, Energy Transition Leader for Oilfield Services at Baker Hughes.
Each tonne of CO2 sequestered is planned to generate approximately US$200 per tonne from the California Low Carbon Fuel Standard and US$50 per tonne of IRS 45Q tax credit. Legislation is pending in Congress to increase the federal tax credit to US$80 per tonne of CO2 and to provide billions of dollars of grants and loans to finance CCS projects in the United States.
