Capstone Energy+ Secures Lease Agreement for Flare Gas Recovery Project with Maurel & Prom in Gabon

C600S Microturbine to Convert Associated Gas into Reliable On-Site Power at Remote Onshore Platform Under 36-Month EaaS Lease

LOS ANGELES--(BUSINESS WIRE)--Capstone Energy+, Inc. (NASDAQ: CEPL) (“Capstone” or the "Company”), a leading provider of behind-the-meter clean microturbine energy solutions for industrial and commercial businesses, as well as solutions designed for emerging datacenter applications, today announced that it is providing a Capstone C600 Signature Series microturbine to Maurel & Prom, an international oil and gas operator for its flare gas valorization project at the company’s onshore asset in Gabon, West Africa.

The project will support Maurel & Prom’s flare gas valorization efforts, in which gas that would otherwise be flared is recovered and converted into a useful form of energy. The microturbine will operate on recovered associated gas to provide electricity for platform operations.

Structured under Capstone’s Energy-as-a-Service (EaaS) business model, Capstone is providing the C600S through its “Lease-to-Own” (LTO) offering, enabling Maurel & Prom to leverage an operating expense-based solution while preserving capital flexibility.

Commissioning is expected in November 2026.

Converting Waste Gas into Clean, Reliable Power

“For operators like Maurel & Prom, flare gas valorization solves two problems at once: it eliminates a meaningful source of emissions and generates the reliable power that remote operations depend on,” said Vince Canino, President and CEO of Capstone Energy+. “Converting fuel that would otherwise be wasted into dependable on-site electricity, in a tropical environment far from any grid, is exactly the kind of application our technology was built for.”

Across Sub-Saharan Africa and other major producing regions, associated gas has long been flared where no capture infrastructure exists, representing both a significant emissions source and wasted energy value. As pressure to eliminate routine flaring intensifies, upstream operators are increasingly seeking proven alternatives. Capstone’s microturbines convert that waste gas into productive on-site power without requiring pipeline connectivity or major infrastructure investment.

Capstone’s microturbine platform is engineered for reliable, continuous operation on variable-composition fuel streams, including associated gas. Its single-moving-part, air-bearing design requires no oil, no coolant, and dramatically fewer service interventions than conventional reciprocating engines, a critical advantage for remote sites where such conditions add significant logistical complexity.

EaaS Lease Model Delivers Capital Efficiency for Field Deployment

The 36-month lease structure reflects a growing preference among upstream operators for capital-efficient energy deployment. Maurel & Prom receives new, factory-direct equipment under fixed periodic payments, preserving capital while securing long-term power reliability. End-of-term options to purchase, renew, or upgrade provide flexibility as the project’s production profile evolves.

“Turning gas that would otherwise be flared into reliable on-site power supports both our environmental goals and the energy needs for our operations in Gabon. Working with Capstone’s technology delivers that reliability while preserving capital flexibility,” said Ibrahim Ben Ameur, Lead Process Engineer, Maurel & Prom.

This project marks Capstone Energy+’s continued expansion in the African upstream energy sector, delivering proven microturbine technology under flexible EaaS commercial structures suited to the realities of remote field operations.
