Drift Energy puts a different spin on wind power. Instead of creating windmill-derived electricity, its plan sees AI-routed hydrofoil sailing yachts generating electricity for electrolysis. Those yachts would then deliver green hydrogen ashore.

Beautifully designed, energy-generating bio-panels that suck up carbon dioxide and pump out biomass for use as fuel or fertilizer – that's the idea behind Mexican startup Greenfluidics and its nanotech-enhanced microalgae bioreactor building panels.

Sesame Solar announced this week what it calls the world's first 100-percent renewable mobile nanogrid. Powered by a wing-like solar panel spread and green hydrogen, the modular nanogrid brings weeks of autonomous electricity where it's most needed.

Japan's solar potential isn't great, but it does sit right next to one of the world's most powerful ocean currents – so the country is searching for novel ways to bulk up its green energy generation in the form of giant deep ocean turbines.

Hydrogen City will eventually harness 60 gigawatts of solar and wind energy, and use it to produce over 2.5 billion kilograms of green hydrogen a year, keeping it underground in storage caverns at the Piedras Pintas salt dome before transport.

Canada's FuelPositive says its modular, container-sized ammonia production units will deliver 100 tonnes of green ammonia a year at costs around US$444/tonne, a big discount on what you'd pay for highly polluting gray ammonia in today's market.

The US Department of Energy has committed US$20 million to an Arizona-based project that will use nuclear energy to create green hydrogen, testing its capability as a liquid backup battery and as a secondary product for nuclear power installations.

China's MingYang Smart Energy has announced an offshore wind turbine even bigger than GE's monstrous Haliade-X. The MySE 16.0-242 is a 16-megawatt, 242-meter-tall behemoth capable of powering 20,000 homes per unit over a 25-year service life.

Germany's Svevind has announced plans for a colossal green hydrogen project that will place some 45 gigawatts of wind and solar energy generation on the vast steppes of Kazakhstan to produce around three million tonnes of green hydrogen annually.

A tiny, cheap molten salt reactor that fits in a shipping container could radically disrupt the nuclear power industry. Denmark's Seaborg says it will mass-manufacture them and deploy them globally on floating barges, on a paradigm-smashing timeline.

Israeli company H2Pro claims its highly efficient water-splitting technology will deliver green hydrogen at less than US$1 per kilogram before 2030. That would leapfrog current projections by 20 years, and spark green revolutions in many industries.

Greener than the best renewable hydrogen production processes, and as cheap as the dirtiest coal-generated H2 out of India – using garbage for fuel that would otherwise sit in landfill. Extraordinary claims for a new H2 plant planned for California.
