The ocean is an immensely powerful force of nature, and our greatest ally to reverse the tides on climate change. By studying the planet’s natural cycles, Captura designed a solution that removes CO2 from the ocean and harnesses its ability to heal the climate—a process known as Direct Ocean Capture.
Developed and proven in Caltech’s laboratories, our unique Direct Ocean Capture technology runs with just two ingredients: seawater and renewable electricity. It extracts CO2 directly from seawater to be permanently stored or reused. This amplifies the natural equilibrium between the ocean and atmosphere, drawing carbon out of the air and into the ocean to rebalance.
Captura’s approach requires no rare-Earth minerals, adds nothing to the ocean, and leaves no chemicals behind. It’s a low-cost, large-scale carbon removal solution that is environmentally sound.

At OXCCU, we are at the forefront of scientific advancement, shaping the future of sustainable aviation fuel production. Founded in 2021 as a spin-out from the University of Oxford, OXCCU is led by CEO Andrew Symes alongside co-founders CTO Dr Tiancun Xiao, Dr Jane Jin and Dr Benzhen Yao. The company is headquartered in the UK, with operations at Begbroke Science Park, Oxford, and London Oxford Airport.
Our mission is to develop the world’s lowest cost, lowest emission pathways to make both jet fuel and chemicals from waste carbon, allowing people to continue flying and using hydrocarbon products without the climate impact.
At the heart of our process is a one-step catalyst and reactor built to convert the widest range of CO₂, CO and H₂ compositions from multiple waste carbon sources, directly into liquid hydrocarbons for fuels and chemicals . Our technology consolidates the traditional production process from a two-step Reverse Water Gas Shift (RWGS) and Fischer Tropsch (F-T) reaction into a single catalytic conversion. Fewer steps, lower energy input and higher yield.
Our catalyst system has leading conversion and selectivity, enabling cost effective liquid hydrocarbon production from a range of waste feedstocks. This ability to work with the broadest range of different syngas compositions, with or without CO2, provides advantages in Power-to-Liquids (PtL), biogas to SAF (GtL) and biomas to SAF (gasification). The focus is always the same: reducing both cost and carbon intensity.
The company’s first demonstration plant, OX1, based at Oxford Airport, produces SAF, branded OXFUEL™, marking a first-of-its-kind achievement and a major step towards scaling a clean, cost-effective alternative to fossil jet fuel. Technoeconomic analysis shows that OXCCU’s technology simplifies fuel production and cuts capital costs by 50% compared to conventional e-fuel or biofuel pathways.

EnergyX is a sustainable energy company focused on direct lithium extraction, refinery and battery technology. Combining these technologies from brine to battery will create a process dramatically lowering the cost of lithium resources. The company’s goal is to develop technology and assets that turn it into one of the premier, low-cost lithium providers for the growing lithium-ion battery industry.
The electric vehicle (EV) and energy storage revolution is generating high demand for lithium, with some analysts forecasting orders-of-magnitude demand increases. As the EV market rapidly expands, millions of large-scale battery packs will be in demand. The estimated annual production of EV’s is 20,000,000 per year. For one 85-kWh car, the price of the lithium in the battery is approximately $2,945 per car. Residential (home) and commercial batteries are also gaining market demand traction, and California has implemented law stating by 2020 all new homes will require solar arrays.
Companies already producing lithium are attempting to increase production as battery cell manufacturers are scaling up lithium-ion production with mega factories and actively acquiring raw materials through long term off-take supply agreements. In the Lithium Triangle, where 50-70% of the world’s known lithium reserve is located, current methods of extraction are based off outdated, natural evaporation pond technology, which takes 18 months, and loses 50-70% of the lithium due to co-precipitation.
Our solution is to optimize and apply a highly scalable lithium extraction membrane to the process. The ability to efficiently extract and aggregate the lithium elements from the salt brines using proprietary, multi-level, synthetic ion separation techniques can increase time efficiency by 100x and recovery rate by 300%.
