GCT helps clients navigate the transition to low-carbon operations with an integrated approach to decarbonization. We develop roadmaps that prioritize the most impactful opportunities, from efficiency improvements and waste-heat recovery to alternative fuel production. Our engineers then implement practical technologies and systems that cut emissions while reducing energy costs. By combining strategic planning with execution, we deliver measurable and lasting decarbonization results.
GCT designs and engineers biocarbon production facilities that convert organic feedstocks into renewable carbon products. We integrate feedstock handling, thermochemical conversion and gas cleaning to produce high‑quality biocarbon while recovering energy from vapours and gases. Our experience ranges from small pilot plants to large‑scale installations that displace coal without major equipment modifications.
From early feasibility through commissioning, our multidisciplinary team manages every aspect of biocarbon projects. We perform mass and energy balances, specify equipment, develop detailed layouts and instrumentation, support permitting and emissions compliance, and coordinate commissioning and operational readiness so that clients can confidently bring sustainable fuel technologies to market.
GCT offers a comprehensive suite of hydrogen services covering safety, technology development and implementation. We help clients safely produce, store and use hydrogen by assessing applicable codes and standards, conducting hazard reviews and defining appropriate materials, instrumentation and storage systems. Our specialists analyse leakage, fire and explosion scenarios and deliver safety training to ensure robust risk management.
Beyond safety, we develop and test hydrogen combustion and reduction technologies, optimize process efficiency, analyse flame characteristics and emissions, and assess materials of construction. We evaluate business cases, benchmark technologies, review readiness levels and design pilot programs. When clients are ready to integrate hydrogen, we audit fuel conversions, assess impacts on processes and materials, define modifications, assist with permitting and manage projects from concept to commissioning.
GCT specializes in Organic Rankine Cycle (ORC) systems that convert industrial waste heat into discounted electricity for plant operations. We provide full-scope services from installation and commissioning to start-up, ensuring reliable integration and measurable energy savings. Alongside Organic Rankine Cycle systems, we also offer other waste heat recovery solutions tailored to client needs.
GCT develops decarbonization roadmaps that chart a practical path toward low‑carbon operations. Our team evaluates opportunities across energy efficiency, waste heat recovery, fuel switching, electrification and carbon capture to identify measures that deliver the greatest emission reductions while maintaining reliability and profitability. Each roadmap is tailored to the client’s processes, equipment and regulatory environment.
We perform technical and economic analyses of candidate projects, prioritize actions based on impact and cost and provide phased implementation plans with performance targets. By bringing together process engineers, energy experts and financial analysts, we help clients turn climate commitments into actionable strategies.
GCT has extensive expertise in energy optimization, including process plant energy intensity assessments, and process unit energy optimization, which directly impact GHG emissions. GCT regularly performs energy assessments for process equipment and off-gas systems. GCT identifies practical approaches to recover heat from the off-gas in the form of steam, preheated air, or direct recycle that can be used in other processes to reduce fuel consumption. Specific capabilities include:
