. . . . CARBON NEGATIVE ENERGY WHAT IS CNE? • Carbon removal refers to any process or system capable of removing and sequestering carbon from the air over its life cycle

• CNE (or BioCCS) refers to any bioenergy process that captures and permanently stores carbon safely underground through carbon capture and storage (CCS) – Indirect Air Capture

• CNE can remove the harmful greenhouse gas carbon dioxide (CO2) from the atmosphere while producing electricity and clean, renewable hydrogen

. . . . CNE l HOW IT WORKS

CES Carbon Negative Energy (CNE) plants use waste biomass fuels that are gasified to produce a synthesis gas. This “syngas” is then used to produce renewable hydrogen (RH2), and/or electricity with full carbon capture using proprietary oxy‐combustion technology

. . . . CNE: WHY NOW? ECONOMICS California’s Declining Carbon Intensity Curve

Revenues have increased from $20 to $250/tonne for Carbon Capture in select markets • Value Proposition for CCS projects today:

o Renewable Hydrogen sales at avoided cost o Federal Tax Credit (45Q); increased from $20 to

$50/tonne CO2 in 2018 o California’s Low Carbon Fuel Standard (LCFS); credit prices 

exceeding $190/tonne

• Concurrently, the Biomass Power industry in California has collapsed due to competition from wind and solar 

o Stranded assets may be used for alternative purposes o Feedstock pricing collapse; long‐term contracts available

• Required CES capture tech. ready for commercial deployment o More than 25 years and $135 million invested

. . . . CNE I OPPORTUNITES FOR CALIFORNIA 

TODAY → TOMORROW • Half the state’s biomass plants shu ered  →  All biomass plants repurposed and life extended

• Criteria pollutants from biomass plants   → Near‐zero atmospheric emissions

• Open field burning of agricultural waste → 

Ag. waste used to produce renewable hydrogen

• Natural gas is used to make hydrogen  →  Renewable hydrogen from ag. and green waste

• Tree mortality and wild fire crisis  → Beneficial use of cleared forestry waste

• Current biomass plants consume water   → CNE plants are net producers of water

• Water shortages in the Central Valley   → Brackish water can be processed with waste heat

. . . . CNE l POTENTIAL FOR CCS IN CALIFORNIA

California Offers Very Large CO2 Storage Capacity: 

• California’s on‐shore sedimentary have capacity for roughly 1,000 years of current CO2 emissions (point source)

• The largest storage capacity identified in the state’s Central Valley basin

. . . . CNE I POTENTIAL FOR BioCCS IN CALIFORNIA • More than 15 idle biomass power plants in California today (>375 MW), with more anticipated to close in the coming years

• Excellent overlay of plant locations with CCS storage sites

• Suitable for delivery to state refineries or the Hydrogen Highway

. . . . CNE DEPLOYMENT I HOW TO ACCELERATE?

1. Fast‐track approval of CCS projects

• Resolution of permanence storage protocol

• Coordination between state agencies and US EPA

2. Greater flexibility in LCFS pathway calculations/monetization/eligibility

• Currently results in a fixed CI, whereas CNE projects may have variable CI attributes

• Increased trading/monetization opportunities

• More favorable interpretation of the regulations

3. Predictability of LCFS pricing to support project financing

• A floor price is optimal, but highly problematic

• Opportunities through the Pollution Control Tax‐Exempt Bond Financing Program
