HALO Hydrogen from Produced Water

The ‘Hydrogen recovery using Arc-plasma Learning Optimization’ (HALO) system creates hydrogen from produced water

Oceanit’s Hydrogen recovery using Arc-plasma Learning Optimization (HALO) System is a novel approach to capturing H­2 from produced water and other waste streams. Hydrogen is abundant on earth but primarily found as part of compounds, such as water or methane. Accordingly, H­2 must be separated from those compounds in order to be used as an energy source. Many processes for this separation exist at varying levels of how “clean” they are for the environment. HALO represents a new step towards generating cleaner hydrogen, reducing a waste byproduct – produced water, and recovering other value-add elements from waste streams.

Hydrogen (H2 as standard gas) has been closely examined for its potential as a fuel as well as a storage and transportation medium for both renewable and non-renewable energies. However, H2 still has prohibitively high costs compared to conventional fossil fuels. As the energy sector addresses the realities of the global climate crisis, the global hydrogen energy storage market is on the rise, with expectations that it will grow at a rate of 8% through 2025. However, the challenges of how to make hydrogen production clean and economically feasible at scale remain.

HALO is a next-gen system that utilizes directed energy combined with advanced AI monitoring and optimization, to improve hydrogen recovery from produced water. HALO’s AI adapts to and adjusts for different types waste streams to maximize production.

Produced water, a highly saline byproduct of oil and natural gas production, is one such waste stream that HALO will be applied to.  Produced water can be passed through HALO to extract large amounts of hydrogen gas, as well as other value-add elements and metals, such as lithium.

The US alone creates 25 billion barrels of produced water per year, which must be disposed of or treated. Current methods for disposing of produced water often include re-injecting the wastewater back into the ground, posing a risk for ecosystems, water contamination, and induced seismicity. HALO creates a solution for both H2 production and produced water treatment by recycling produced water to extract minerals, metals, and hydrogen gas. In addition, HALO’s modular, mobile system will allow for scalable processing at various sites.

HALO is one of several technologies that Oceanit is developing under EDGE (Energy Decarbonization for the Global Environment) to support the global energy transformation and make hydrogen a viable clean-burning fuel source for a greener future.
