HYDRON (Acid Lake Neutralization with Power Generation)
HYDRON is a dual-purpose technology that neutralizes acid lakes while generating clean electricity.
The challenge
The problem this technology addresses
Primary use cases: abandoned acid mine lakes, industrial runoff, acid mine drainage; off-grid 24/7 power at remediation sites.
Industries and users: mining remediation authorities, off-grid power operators, environmental projects.
Scale: modular (50–100 kW/module); e.g., 250 modules at Lake Mathiatis (Cyprus) ≈ up to 25 MW.
ARBOK solution
How the ARBOK system creates value
HYDRON is a dual-purpose technology that neutralizes acid lakes while generating clean electricity. Acidic mine water (pH ~3) and an alkaline side (pH ~8) are linked through a patented salt bridge, forming a galvanic circuit that produces continuous current. Over time it neutralizes the lake to pH ~7, captures and monetizes byproducts (hydrogen, chlorine, oxygen, precipitated metals), and keeps generating power after neutralization. Unlike conventional remediation, it pairs ecological restoration with energy revenue.
Acidic lake water (pH ~3) and alkaline tanks (pH ~8) are connected via a high-efficiency ion-exchange salt bridge, establishing an electrochemical potential that drives current through corrosion-resistant graphene–graphite electrodes. The reaction neutralizes the acid (toward pH ~7), precipitates heavy metals as solids, and releases capturable gases (H₂, Cl₂, O₂). The system can use reverse-osmosis brine as a reactant, avoiding brine waste.
Limitations: gas handling (H₂/Cl₂ safety); salt-bridge maintenance; output depends on lake chemistry/volume.
Market and application
Commercial opportunity
Thousands of abandoned acid mine lakes worldwide carry remediation liability; pairing cleanup with power and byproduct revenue is a strong fit for mining regions under closure obligations and energy scarcity.
Cost per module: $36 000 (big-bag) or $55 000 (tank). Full deployment (250 modules): $9 million (big-bags) or $13.75 million (cisterns). Annual revenue potential: electricity ~$4.15 million, gases (H₂, Cl₂) ~$29.21 million, metals ~$0.1 million → total ~$33.46 million. Payback: ~2.7 years (big-bag) / ~4.1 years (cistern).
Use cases
Where the technology can be applied
Primary use cases: abandoned acid mine lakes, industrial runoff, acid mine drainage; off-grid 24/7 power at remediation sites.
Industries and users: mining remediation authorities, off-grid power operators, environmental projects.
Scale: modular (50–100 kW/module); e.g., 250 modules at Lake Mathiatis (Cyprus) ≈ up to 25 MW.
Steps: lake chemistry/volume survey → module count sizing → install (tanks or big-bags) → commissioning. Continuous, automated; gas-safety and salt-bridge upkeep are the main operational tasks.
Deploys at acid lakes/tailings; pairs with RO brine streams and ARBOK acid-lake water recovery; gas offtake to industrial users; grid or off-grid power.

Overview
HYDRON is a dual-purpose technology that neutralizes acid lakes while generating clean electricity. Acidic mine water (pH ~3) and an alkaline side (pH ~8) are linked through a patented salt bridge, forming a galvanic circuit that produces continuous current. Over time it neutralizes the lake to pH ~7, captures and monetizes byproducts (hydrogen, chlorine, oxygen, precipitated metals), and keeps generating power after neutralization. Unlike conventional remediation, it pairs ecological restoration with energy revenue.
Applications
Primary use cases: abandoned acid mine lakes, industrial runoff, acid mine drainage; off-grid 24/7 power at remediation sites.
Industries and users: mining remediation authorities, off-grid power operators, environmental projects.
Scale: modular (50–100 kW/module); e.g., 250 modules at Lake Mathiatis (Cyprus) ≈ up to 25 MW.
Operating Principle
Acidic lake water (pH ~3) and alkaline tanks (pH ~8) are connected via a high-efficiency ion-exchange salt bridge, establishing an electrochemical potential that drives current through corrosion-resistant graphene–graphite electrodes. The reaction neutralizes the acid (toward pH ~7), precipitates heavy metals as solids, and releases capturable gases (H₂, Cl₂, O₂). The system can use reverse-osmosis brine as a reactant, avoiding brine waste.
Limitations: gas handling (H₂/Cl₂ safety); salt-bridge maintenance; output depends on lake chemistry/volume.
Key Parameters
Module power: 50–100 kW; 250 modules ≈ up to 25 MW. Post-treatment water: ~pH 7.
Electrodes: graphene–graphite or graphene–graphene. Alkaline side: 40–60 m³ tanks or rubberized big-bags; acid side: lake water direct.
Gas output per module (with brine): H₂ + Cl₂ ~13.9 m³/hr; O₂ ~1–2 m³/hr; SO₂/H₂S ~0.1–0.5 m³/hr. Metal capture: 0.1–1 kg/hr.
Architecture and Components
Acid half-cell (lake water); alkaline half-cell (tanks/big-bags); patented ion-exchange salt bridge; graphene-based electrodes; gas capture and metal-precipitate collection; power conditioning. Modular, scalable by module count.
Advantages
Technical: neutralization and generation in one system; corrosion-resistant electrodes; continuous output after neutralization.
Economic: revenue from electricity, gases, and metals (see economics); fast payback.
Environmental: neutralizes acid lakes to pH 7; locks metals as solids; captures all gases; enables lake reuse (agriculture, recreation, aquifer recharge); consumes RO brine instead of dumping it.
Strategic: turns a remediation liability into an energy asset; off-grid power in mining regions.
Integrations
Deploys at acid lakes/tailings; pairs with RO brine streams and ARBOK acid-lake water recovery; gas offtake to industrial users; grid or off-grid power.
Deployment & Operation
Steps: lake chemistry/volume survey → module count sizing → install (tanks or big-bags) → commissioning. Continuous, automated; gas-safety and salt-bridge upkeep are the main operational tasks.
TRL
TRL 6 (confirmed by Michael). Prototype validated in a relevant environment; detailed module design, gas/metal/power figures, and a sized deployment case (Lake Mathiatis, Cyprus). Remaining: field-scale pilot and permitting for full deployment.
Market Potential
Thousands of abandoned acid mine lakes worldwide carry remediation liability; pairing cleanup with power and byproduct revenue is a strong fit for mining regions under closure obligations and energy scarcity.
Typical Project Economics
Cost per module: $36 000 (big-bag) or $55 000 (tank). Full deployment (250 modules): $9 million (big-bags) or $13.75 million (cisterns). Annual revenue potential: electricity ~$4.15 million, gases (H₂, Cl₂) ~$29.21 million, metals ~$0.1 million → total ~$33.46 million. Payback: ~2.7 years (big-bag) / ~4.1 years (cistern).
Risk Factors
H₂/Cl₂ gas handling and safety/permitting; gas offtake market for revenue case; salt-bridge durability; needs field-scale pilot; chemistry-dependent output.
