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.

Ovo Energy has launched a suite of domestic energy products, including a V2G charger that gives EV drivers the flexibility to draw electricity from the grid when it's cheap and sell it back during peak demand hours. And if users get the balance right, they could effectively drive their EVs for free.

While world leaders meet in Paris to discuss reducing carbon emissions believed to contribute to climate change, the government of Gibraltar is putting its own renewable energy plan into action.

In an advance that could help photoelectrochemical cells (PECs) play a stronger role within the smart grid, researchers at the University of Texas, Arlington have found a way to store the electricity generated by this clean energy source for extended periods of time.
