When I say “green hydrogen,” I mean hydrogen produced by electrolyzers using electricity that comes from zero-carbon sources such as wind, solar, or other renewables. That’s important because “blue” hydrogen (made from fossil gas with carbon capture) or “grey” hydrogen (from fossil gas without capture) […]

Mining in remote places is gritty work. No roads, patchy grid, diesel trucks lined up like lifelines, and mountains of fuel delivered at high cost. So when you hear about green hydrogen powering remote mining operations, it sounds almost too good to be true: clean […]

Shoving “green hydrogen” into an existing refinery is not like plugging in a new coffee machine. It’s more like remodeling a busy kitchen while dinner service is still running — you must think about where the ovens sit, how the gas lines run, what the […]

Seasonal energy storage means saving energy for months, not minutes or hours. It’s the difference between having a battery to cover your evening cooking and having a system that stores summer sunshine to heat homes through winter. In many climates, renewable supply and demand are […]

In emerging markets, the story turns on policy: the rules, incentives, and public actions that make private investors say “yes” and communities say “trust it.” This article walks you through the full sweep: why incentives matter, which incentives work (and why), how to design them […]

Designing an electrolysis-to-chemical-plant integration is like choreographing a ballet between electrons, water, catalysts, pipes, and human teams. You can’t simply bolt an electrolyzer next to a reactor and hope for the best. To create a reliable, efficient, and bankable green hydrogen–to–chemical plant you must think […]

What does green hydrogen actually mean for a country like Nigeria, where heavy industry — cement, fertilizers, refining, steel, and petrochemicals — burns a lot of fossil fuel every day? Can green hydrogen realistically cut those emissions, create jobs, and strengthen energy security? In this […]

Green hydrogen is suddenly everywhere in energy conversations. It’s the idea of using renewable electricity — from wind and solar — to split water into hydrogen and oxygen, storing energy in a chemical form. That’s useful, sure, but what happens when you plug that hydrogen […]

Green hydrogen sounds like a simple idea: take renewable electricity, run it through water to split out hydrogen, and then use that hydrogen as a clean fuel. But the moment you say “let’s shove hydrogen into existing natural gas pipelines,” complexity shows up like a […]
