Proven at commercial scale.
TRIG™ is not a concept awaiting its first plant. The complete coal-to-syngas train was designed, built, and operated at a 582 MW commercial IGCC facility in the United States — anchored by the two largest gasifiers ever deployed in IGCC service, nearly twice the size of the next largest.
Design targets, met
01The measure of a first-of-a-kind plant is simple: did the process do what the design said it would? At high-load operation, the TRIG™ train approached or met every major design target.
| Process performance | Design basis | Achieved | % of design |
|---|---|---|---|
| Coal feed rate | 400 kpph | 394 kpph | 98.4% |
| Raw syngas flow | 1,285 kpph | 1,282 kpph | 99.7% |
| Carbon conversion | >97% | ~98% | Target met |
| Particulate removal | Clean-syngas spec | >99.99% | Target met |
| Syngas heating value (LHV) | 121 Btu/scf | 120 Btu/scf | 99.2% |
| Syngas quality | Expected | Actual |
|---|---|---|
| H₂ | 32.0% | 31.2% |
| CO₂ | 5.0% | 4.6% |
| CO | 1.9% | 1.9% |
| CH₄ | 3.0% | 3.1% |
| LHV | 121 Btu/scf | 120 Btu/scf |

Operated across the full
commercial envelope
02
The gasifiers did not run at a single flattering set point. Over 224 days of commercial-scale operation, they ran across the entire envelope a real project needs — on one of the most difficult feedstocks in the world.
The feedstock was the hard case, on purpose. The facility ran on a friable, highly variable lignite averaging 45% moisture — with stockpiles containing roughly 60% fines. This is precisely the class of low-rank coal that conventional gasifiers cannot process, and that makes up over half of global reserves.
The plant proved it could be prepared and fed at commercial scale: dried below 20% moisture, delivered at rates up to 2,400 tons per hour, with the pressurized feed system continuously available over nearly a year of operations.
Scale-up held. The transport gasifier scaled roughly 73× from its development platform — and the feed system 20× per feeder — while sustaining the mixing, conversion, and reliability behavior established across 20,000+ hours of prior development operations.
Campaigns of more than 200 continuous days validated the continuous dry-ash systems that distinguish TRIG™ from slagging designs.
Reliability, by design
03The failure modes never start
Operating 600–700°F below the ash melting point eliminates slag taps, black water, and refractory erosion — the outage drivers that force conventional plants to buy spare gasifiers.
Availability, train by train
Excluding a one-time shop-installed refractory defect — identified and corrected — the two gasifiers achieved 99.98% and 100% availability, matching more than a decade of development-platform experience.
Capital follows reliability
Conventional slagging gasifiers typically require a spare unit — roughly 30% more capital. TRIG™’s inherent reliability removes that line item entirely.
Capture and clean-up,
demonstrated end to end
04
Gasification’s environmental advantage is that contaminants are removed from a compact, pressurized gas stream before use — not scrubbed from flue gas after combustion. The facility proved it in operation.
Three decades in the making
05TRIG™ was developed in partnership with the U.S. Department of Energy — matured methodically from development platform to commercial deployment over nearly three decades.
Development at national scale
20,000+ hours of gasification R&D at the U.S. Department of Energy’s Power Systems Development Facility in Wilsonville, Alabama.
Commercial construction
A 582 MW IGCC facility built in the United States, anchored by the two largest TRIG™ gasifiers ever constructed.
Commercial operations
5,300+ hours across two independent trains. 650,000+ tons gasified. Greater than 99% gasifier availability. 65% carbon capture validated, with ~100,000 tonnes of CO₂ delivered at pipeline specification.
Technology licensing
Latitude licenses TRIG™ for chemical and fuel production worldwide — carrying the complete operating record, lessons learned, and design corrections into every new project.
About the broader project
The facility’s wider power-generation scope was suspended in 2017 as collapsing U.S. natural-gas prices reshaped power economics — a market decision, not a technical one. The gasification island itself met or approached every major design target it was built to prove, and the complete engineering record from that campaign now de-risks every project that follows. Latitude Energy did not own the referenced facility and had no role in any phase of its engineering, procurement, or construction. Latitude’s practice draws on the program’s publicly available engineering and project reporting.
Bankability begins where technology risk ends. TRIG™’s technical prowess was demonstrated on the world’s most difficult coals — an operating record lenders can diligence, not a risk they must price.
