HALO Hydrogen Production

The ‘Hydrogen recovery using Arc-plasma Learning Optimization’ (HALO) system converts waste streams to fuel.

Oceanit’s Hydrogen recovery using Arc-plasma Learning Optimization (HALO) System is a novel approach to capturing H­2 from wastewater 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 for use 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, as well as 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 plasma gasification, combined with advanced AI monitoring and optimization, to improve hydrogen recovery from waste. HALO’s AI adapts to and adjusts for different 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.

The US alone creates 25 billion barrels per year of produced water waste. Current methods for disposing of produced water often include re-injecting the wastewater back into the ground, posing a risk for ecosystems, water contamination, toxic leaks, and induced seismicity. HALO creates a solution for both H2 production and water treatment by recycling this 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.
