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

Utility capital projects & 2026 energy trends
Utility capital projects are facing mounting delays and cost pressures in 2026, even as AI-driven demand fuels record capex. Meanwhile, the upstream oil and gas market is stabilizing around a normalizing shale cost curve, bulk liquid storage operators are shifting toward capability-driven growth, and the energy transition is exposing critical minerals bottlenecks that are pushing […]
U.S. refining capacity is gradually consolidating into larger, more complex facilities
U.S. refining capacity shows limited overall growth, but the structure of the system is shifting. Expansions at large, complex refineries are driving changes on the supply side, while smaller plants face cost and operational constraints that are forcing exits. This is steadily concentrating capacity in fewer, more sophisticated facilities. Key drivers capacity consolidation: Geographic concentration […]
