NASEM announces provisional committee for new study on life cycle analyses of low-carbon fuels
Low carbon fuel standards, such as the Federal Renewable Fuel Standard and the California Low Carbon Fuel Standard, are major US programs for reducing greenhouse gas (GHG) emissions from transportation fuels. These standards rely on life cycle assessment (LCA) as a tool to estimate fuel GHG emissions.
However, current LCAs differ notably in how they are implemented, with disagreements pertaining to data quality, modeling approaches, and key assumptions.
The ad hoc NASEM committee will assess current methods for estimating lifecycle greenhouse gas (GHG) emissions associated with transportation fuels (liquid and non-liquid) for potential use in a national low-carbon fuels program. In carrying out its assessment, the committee will identify the general characteristics and capabilities of GHG emissions estimation methods that would be commonly needed across various types of low-carbon fue

“We have a clear recognition here that low-carbon fuels are going to be in much greater demand going forward,” he said.
“The interesting thing here from our perspective is that we’ve been able to come up with low-carbon fuel projects and projects that have enabled us to reduce the carbon intensity of some of our other fuels that have significant returns also,” he added.

Valero in March announced it was joining with BlackRock Global Energy & Power Infrastructure fund and Navigator to build a carbon capture and storage pipeline system across the Midwest, which will connect to eight of its 13 ethanol plants and have the capacity to store 5 million mt of CO2 annually.

The so-called 45Q carbon sequestration program currently expires in 2025.
The bill introduced April 19 would increase credits to $85/mt of trapped carbon for industrial facilities, power plants and direct air capture plants that store carbon in salt caverns, up from the current $50/mt. Carbon stored in oil and gas fields would generate credits of $50/mt, up from $35/mt, under the proposal.
Drillers like Occidental Petroleum have relied on the tax credits in recent years for enhanced oil recovery, which pumps captured CO2 into reservoirs to re-pressurize them and increase production.
Lead time an issue
Energy legislation passed in December 2020 extended the program to projects that start construction by the end of 2025, but the Carbon Capture Coalition said developers need more lead time to take advantage of the incentive.
