Hydrogen-Rich Irrigation for Drought-Stressed Vineyards
A structural trend, not an isolated bad year
2026 French wine yields confirm a structural trend, not an isolated bad year: Champagne production fell nearly 49% versus 2025 (Comité Champagne), following spring frost and prolonged summer drought. In Bordeaux, yield losses exceed 20% in the worst-affected areas. This is the industry's third consecutive difficult harvest, and growers are actively seeking technical solutions to build vine resilience against water stress.
In 2026 Champagne production fell nearly 49% versus 2025 (Comité Champagne) after spring frost and prolonged summer drought, with yield losses above 20% in the worst-affected Bordeaux areas. HERO Irrigation installs in-line on an existing drip network and delivers 20 L/min of water at a sensor-verified 3,000–5,000 ppb of dissolved hydrogen, covering roughly 10 hectares per unit. YBG Global makes no yield promise — only the machine's output, purity and stability are certified.
A technological response to water stress
Nano-bubble hydrogen-rich irrigation water improves water-use efficiency and plant stress resilience — a direct technological response to the drought and heat pressure viticulture now faces.
HERO Irrigation generates hydrogen on site by PEM/SPE electrolysis: the 99.99% purified hydrogen stream is dissolved as nano-bubbles into your existing irrigation main at a sensor-verified 3,000–5,000 ppb. Nano-bubbles — below roughly 200 nanometres — carry negligible buoyant lift, so they stay in suspension and travel through the pump, filter bank and emitters instead of venting in the mixing tank.
Installation is in-line on the existing network: 20 L/min of hydrogen water, around 10 hectares of drip coverage per unit, 800 W single-phase supply, stainless cabinet 550 × 350 × 970 mm, 83 kg including accessories, IP54, CE and EMC (2014/30/EU) compliant. No change to your fertigation regime is required — hydrogen is an additional parameter, measured and logged separately.
Pure hydrogenation — nothing added, nothing left behind
Our systems use PEM (Proton Exchange Membrane) electrolysis to split water directly into hydrogen and oxygen using an electrical current — no magnesium, minerals, or chemical additives are introduced at any stage. What goes into the irrigation line is water enriched with dissolved hydrogen, and nothing else.
For irrigation specifically, this matters: methods that rely on mineral or chemical reactions to generate hydrogen can leave residues in the water — a real consideration for soil chemistry, root-zone health, and long-term vineyard management. Electrolysis-based hydrogenation avoids that question entirely, delivering hydrogen-enriched water with no additive residue to account for.
Lower input costs, not just higher yield
Field data on hydrogen-rich water irrigation points to a second potential benefit alongside yield: lower fertiliser dependency.
A peer-reviewed two-year cherry tomato trial (Li et al., 2024, Plants) found that hydrogen nanobubble water applied without any fertiliser at all produced higher yield, sugar–acid ratio, and lycopene content than a conventional fertiliser-only control group. In other words, the hydrogen treatment didn't just reduce how much fertiliser was needed — in this trial, it outperformed fertiliser entirely.
For growers facing rising input costs, this points to hydrogen-rich irrigation as a genuine input-cost lever, not only a yield or quality improvement.

Trial data, on the record
Hydrogen-rich water irrigation has been studied across a range of crops and trial designs. These are the two strongest data points on file — each labelled with its evidence standing.
Cherry tomato — two-year controlled study
Yield per plant up 39.7% and 26.5% in the 2021 Shanghai trial and 39.4% and 28.2% in the 2023 Nanjing trial against conventional-fertiliser controls, with improved fruit quality and root-zone microbial activity.Source: Li et al.
