Carbon-Negative Energy (CNE)

During the 2015 United Nations Climate Change Conference in Paris, over 180 nations set an aspirational goal of limiting global temperature increase to 1.5°C compared to pre-industrial levels. In order to meet this goal, the Intergovernmental Panel on Climate Change has reported the deployment of large scale “carbon-negative” cycles are needed by 2040.

One type of carbon-negative technology that has generated significant interest is biomass energy production combined with carbon capture and storage (CCS), known as BioCCS or BECCS. BioCCS has enormous potential to remove significant amounts of the greenhouse gas (GHG) carbon dioxide (CO2) from the atmosphere while producing renewable fuels and/or electricity.

CES' oxy-combustion technology offers a carbon-negative energy (CNE) solution that is both technologically feasible and economically viable. The systems use proven and reliable aerospace technology to produce clean power, water, and nearly pure CO2 that is easily captured for permanent storage or commercial sale. When using a biomass fuel that consumes carbon over its lifetime and capturing and permanently storing the produced CO2, the process results in net negative carbon emissions, essentially scrubbing the harmful greenhouse gas from the atmosphere.

The California market offers a unique opportunity for CES’ CNE plants. Due to the severe drought conditions that California has experience over last several years and numerous traditional biomass power plants closing around the state, there is an excess of forestry and agricultural waste.  Biomass plant closures have left farmers with few choices to dispose of their waste and have increased the number of open field agricultural burns, further exacerbating the poor air quality in the state's Central Valley. Deployment of CES’ CNE plants provides a mechanism for simultaneously solving multiple challenges plaguing our state by providing responsible disposal for the abundance of wood waste while improving the Valley’s air quality and supporting the State’s ambitious goals to reduce GHG emissions (recent state mandate requires 100% carbon-free electricity by 2045).  

A recent study has found that commercial deployment of CNE plants can support both California’s power and transportation sectors. Below is a simplified schematic showing how the plants can produce renewable electricity, natural gas (RNG), or hydrogen (RH2), or a combination, that can feed into the State’s existing infrastructure. CES is developing our first CNE project, a small-scale plant at a site in the Central Valley near Bakersfield, California as part of a commercial demonstration. Full operations are expected in late 2021-early 2022, to be followed by a deployment of a fleet of CNE plants across the state.

Check out this PowerPoint presentation for more information on CNE and our plan to deploy carbon-negative energy plants across California.
