Report: Waste biomass can help California meet net-zero goal | Cluster de Biocombustibles Sólidos

A new report released by Lawrence Livermore National Laboratory has determined California can achieve its goal of carbon neutrality by 2045 at modest cost using technology that is already demonstrated and mature, including carbon capture from waste biomass utilization.

California Executive Order B-55-18 was signed by Gov. Jerry Brown in September 2018. It sets a statewide goal to achieve carbon neutrality as soon as possible, and no later than 2045, and maintain net negative emissions thereafter.

LLNL announced the results of a new study on Jan. 30 that determined that goal is feasible. That study, titled “Getting to Neutral: Options for Negative Carbon Emissions in California,” identified a robust suite of technologies that can allow the state to become carbon negative by 2045. According to LLNL, its report details a thorough assessment of the advanced carbon reduction technologies now available, their costs, as well as the tradeoffs necessary to reach the state’s decarbonization goal.

“Our findings give us confidence that this combination of negative emissions technologies and the state’s existing ambitions put the finish line in reach for California,” said Roger Aines, LLNL’s Energy Program chief scientist and the lead on the project. “The report’s findings also indicate we could become carbon neutral sooner than anticipated, at a cost less than expected, while boosting California’s economy and creating quality jobs in areas such as the Central Valley. Important co-benefits to air quality and wildfire prevention also will bring welcome relief to our state.”

The report focused on three pillars of negative emissions: natural and working lands, carbon capture from waste biomass utilization, and direct air capture. According to LLNL, the team identified a portfolio of approaches for achieving greater than 125 million tons per year of negative emissions for California by 2045 and evaluated the scope of state and private investment to best achieve the goal.
