About GECS

Pioneering the Path to Net-Zero Aviation

Green Earth Carbon Solutions (GECS) is developing a transformative platform for producing electro-Sustainable Aviation Fuel (eSAF) at scale through integrated Power-to-Liquid (PtL) facilities powered by proprietary reversible Solid Oxide Cell (rSOC) technology. Our mission is to make sustainable aviation fuel commercially viable and available at the scale the industry requires to meet its decarbonization commitments.

A Strategic Technology Partnership

GECS holds a 40-year Joint Venture agreement with a leading Chinese technology company that provides access to cutting-edge SOEC and SOFC stack technology. This partnership, forged over two decades of dedicated research and development, establishes a durable competitive moat in the rapidly growing sustainable aviation fuel market and ensures GECS has preferential access to continuously improving stack designs.

Integrated Energy Architecture

Each GECS PtL facility integrates a 100 MW Solid Oxide Electrolysis Cell (SOEC) co-electrolysis plant with a 150 MW Solid Oxide Fuel Cell (SOFC) Combined Heat and Power (CHP) system. The SOFC provides all electrical and thermal energy required for plant operations via direct DC coupling, eliminating conversion losses and significantly improving overall energy efficiency. This self-powered architecture enables GECS plants to operate at a stable 90% capacity factor, independent of grid intermittency or weather conditions.

Market Opportunity

A Structural Supply Deficit Through 2040

The sustainable aviation fuel market represents one of the most compelling decarbonization opportunities globally, driven by the near-impossibility of electrifying long-haul aviation and the sector's growing contribution to greenhouse gas emissions. Aviation accounts for approximately 2.5% of global CO2 emissions, and this share is projected to grow significantly as other transport sectors decarbonize faster.

Converging regulatory frameworks across major aviation markets are creating an unprecedented structural supply deficit that is expected to persist through at least 2040. GECS is positioned to capitalize on this supply-demand imbalance through its cost-advantaged PtL process, which eliminates dependence on variable renewable electricity by generating its own power internally through the SOFC CHP system fueled by renewable natural gas.

Our Technology

Reversible Solid Oxide Cell Platform

GECS's core technology is based on reversible Solid Oxide Cells (rSOC), which operate in both fuel cell mode (SOFC) and electrolysis mode (SOEC). This dual-mode capability, developed over two decades of R&D by our JV partner, enables a tightly integrated energy cascade that maximizes overall plant efficiency far beyond conventional approaches.

⚡

SOFC Combined Heat & Power

The 150 MW SOFC CHP system generates 82.5 MW of electrical output at 55% efficiency and 52.5 MW of thermal output, achieving a combined CHP efficiency of 90%. Thermal energy is directly utilized for SOEC feedstock preheating, DAC sorbent regeneration, and process heating.

⚖

SOEC Co-Electrolysis

The 100 MW SOEC simultaneously converts steam and CO2 into syngas at a precisely controlled 2:1 H2:CO molar ratio, ideal for Fischer-Tropsch synthesis. Operating at 1.3V cell voltage, it produces 32,170 Nm3/h of syngas while generating high-purity oxygen as a saleable byproduct.

✈

Fischer-Tropsch Synthesis

Velocys microchannel FT reactors convert syngas into hydrocarbons at 85% conversion efficiency with an 80% eSAF yield. The product slate is optimized for the C8-C16 jet fuel range using the Anderson-Schulz-Flory distribution model, maximizing aviation fuel output.

🌳

Direct Air Capture

Integrated DAC technology utilizes SOFC waste heat for sorbent regeneration, providing a portion of the CO2 feedstock directly from ambient air. This creates a truly carbon-neutral fuel pathway when combined with biogenic RNG as the SOFC fuel source.

💧

ZLD Water Treatment

The Zero Liquid Discharge system recycles FT reaction water and other process water streams, providing makeup water for SOEC steam generation. This closed-loop approach eliminates liquid waste discharge and reduces freshwater consumption.

📈

Direct DC Coupling

The SOFC and SOEC systems are directly DC-coupled, eliminating AC-DC conversion losses and significantly improving overall energy efficiency. This integration is central to GECS's competitive advantage over grid-connected electrolyzer approaches.

rSOC Technology
Key Technical Parameters

Operating at 650°C for Maximum Efficiency

The high operating temperature of 650°C is central to the technology's efficiency advantage. At this temperature, the thermodynamic energy requirement for electrolysis is significantly reduced compared to low-temperature alkaline or PEM electrolyzers, as a substantial portion of the energy input is supplied as thermal energy rather than electrical energy.

The CO2 conversion rate is 68.1% and the H2O conversion rate is 85%, with unreacted feedstock separated and recycled to the SOEC inlet. Annual feedstock requirements are 243,702 tonnes of CO2 and 159,748 tonnes of water per plant per year, totaling 403,448 tonnes of feedstock annually.

Environmental Impact

Closing the Carbon Loop

GECS facilities are designed with environmental stewardship at their core. By combining Direct Air Capture, Zero Liquid Discharge water treatment, and the use of renewable natural gas, each plant operates as a nearly closed-loop system that minimizes environmental impact while maximizing sustainable fuel output.

The integrated approach means that CO2 is captured from the atmosphere, combined with water, and converted into clean-burning aviation fuel. When that fuel is burned in aircraft engines, the CO2 returns to the atmosphere, completing a circular carbon cycle that does not add net new carbon emissions. This is the fundamental promise of Power-to-Liquid eSAF technology.
