DECA®

Decarbonized Ecosystem Assessment

What Is DECA®?

DECA® is a methodology for modeling energy-mass-economic flows in industrial systems—enabling strategic evaluation of decarbonization pathways that create business value rather than compliance cost.

The Challenge

Most energy transition analysis treats decarbonization as a constraint to be satisfied at minimum cost. DECA® reframes it as an optimization problem: How can we reconfigure energy systems to simultaneously reduce emissions and unlock business value?

Three-Flow Integration

Energy Flows

Grid availability, renewable generation profiles, storage dispatch, backup capacity requirements

Example: Solar generation curve vs. industrial load profile; battery sizing for peak shaving and grid outage backup

Mass Flows

Production volumes, feedstock consumption, emissions accounting, material balances

Example: Diesel saved by grid connection → oil freed up for export; natural gas displaced by renewables → feedstock for chemical production

Economic Flows

Capital investment, operating costs, revenue impacts, carbon pricing exposure, financing structure

Example: NPV optimization across capital staging options; sensitivity to fuel prices, carbon taxes, and renewable subsidies

Methodology Steps

  1. Baseline Characterization: Map current energy system (sources, consumption patterns, emissions, costs)
  2. Constraint Identification: Define hard limits (grid capacity, land availability, regulatory mandates) and soft limits (capital budget, operational risk tolerance)
  3. Scenario Generation: Explore thousands of energy configurations (grid, solar, wind, storage, backup) across operational scenarios
  4. Multi-Objective Optimization: Identify pathways that maximize NPV while achieving emissions targets—or minimize emissions within budget constraints
  5. Risk Quantification: Model sensitivity to grid reliability, renewable intermittency, fuel price volatility, carbon pricing
  6. Implementation Roadmap: Phase capital deployment, operational transitions, and performance validation milestones

Value Unlocking Mechanisms

DECA® reveals decarbonization opportunities that create, not destroy, value:

Fuel Displacement

Diesel or natural gas saved can be sold at market prices or reallocated to higher-value uses

Operating Cost Reduction

Grid + solar often cheaper than on-site fossil generation, especially in remote locations

Production Capacity

Eliminating energy bottlenecks can unlock constrained production capacity

Carbon Credit Revenue

Verified emission reductions may generate tradable credits or tax benefits

Block 10 OME Case: 3.4M Barrels Unlocked

Block 10 OME in Ecuador historically consumed diesel for power generation. DECA® modeling revealed that shifting to grid + solar + storage would:

  • Eliminate 3.4 million barrels of diesel consumption over project lifetime
  • Free up equivalent oil production for export at market prices
  • Reduce operating costs by 40% (grid + solar cheaper than diesel logistics in Amazon region)
  • Cut emissions by 85%
  • Achieve 18-month payback period

This was not a compliance project. It was a profit-generating investment that happened to decarbonize operations—because DECA® identified the economic value hidden in the energy transition.
