Emerald Operational Update: August 2025 to February 2026
Coal-Bed Methane Power and SOFC Evaluation
From an operational standpoint, Emerald generates electricity from native coal-bed methane using on-site power generation units. As a result, when GenSets operate as planned, monthly runtimes exceed 90 percent, confirming the reliability of the gas resource.
The primary constraint has not been fuel quality or availability. Since this is the case, attention has shifted to the maintenance requirements of traditional generator sets (GenSets).
Challenges with Conventional GenSets
Methane-powered electricity systems that rely on GenSets require frequent servicing. Mechanical wear, scheduled maintenance, and unplanned downtime increase costs and can disrupt operating cycles. In practice, these issues persist even during periods of strong runtime and limit long-term operational efficiency.
Reducing maintenance exposure is now a priority as Emerald evaluates alternative power generation technologies suited for continuous operation.
Evaluating Solid Oxide Fuel Cell Power Systems
Given these priorities, Emerald is reviewing a potential partnership with a Solid Oxide Fuel Cell (SOFC) provider. SOFC technology remains early in commercial use, yet several manufacturers are advancing industrial fuel cell systems for distributed power applications.
Solid oxide fuel cell systems contain almost no moving parts (see diagram above). As a result of this design, mechanical wear is reduced, and operating cycles remain more stable—all positioning SOFCs as a low-maintenance option for coal-bed methane electricity generation.
Next Steps
Emerald is assessing how SOFC systems could integrate with existing coal-bed methane infrastructure. The evaluation centers on system reliability, maintenance reduction, and long-term operating performance within a broader distributed energy strategy.
