ADI independently assessed engineered geothermal system economics using expert elicitation and lifecycle cost modeling. Drilling depth, well productivity, stimulation costs, and surface plant design were treated explicitly to capture uncertainty ranges in LCOE outcomes. Results highlighted where cost reduction efforts would have the greatest impact on commercial viability.
The client
U.S. Department of Energy

Newsletter: EU CBAM, MDI growth, and other chemical insights
In the July 2026 edition, we examine how carbon regulation, portfolio optimization, and emerging technologies are reshaping the chemical industry. The EU’s Carbon Border Adjustment Mechanism (CBAM) is increasing cost pressure on emissions-intensive imports and accelerating the shift toward lower-carbon supply chains, while evolving chemical regulations continue to influence compliance and sustainability strategies. Meanwhile, investments, […]
