Gany Gunawan evaluated the feasibility of implementing carbon capture & sequestration technology at the City of Tampa’s carbon-intensive facility.


The City of Tampa recognizes that its operations produce greenhouse gas (GHG) emissions, which is why the city is eager to explore opportunities to implement methodologies aimed at reducing GHG emissions. To support this endeavor, Climate Corps enlisted Gany Gunawan to conduct an evaluation on the feasibility of piloting a Carbon Capture & Sequestration (CCS) project at the City’s McKay Bay Waste to Energy (WTE) Facility.


Gany conducted this evaluation by assessing three components.

  • First, the type of CO2 capture technology for WTE retrofitting was considered. This included assessing the land footprint requirement, reduction of power plant output, and additional water consumption for cooling treatment. 
  • Second, the characterization of the geological framework for onsite CO2 sequestration and off-site CO2 sequestration was completed. Pipeline distance and tipping fee(s) are considered for the off-site sequestration option.
  • Third, a financial analysis was conducted, in which the federal carbon tax credit (Inflation Reduction Act, IRA) was considered. Gany used the cost of electricity metric to estimate profitability from the City of Tampa’s Power Purchase Agreement (PPA) contract. 

Potential Impact

The initial concept design calculations indicate that retrofitting McKay Bay Waste to Energy (WTE) Facility with an off-site CO2 sequestration facility creates the potential to reduce current CO2 emissions by 75%, amounting to approximately 82,500 metric tons CO2 per year. To put this in perspective, this reduction is equivalent to removing 18,000 internal combustion passenger cars off the road annually.
