The government of Uruguay has launched ambitious plans to make hydrogen and green fuels.
The country generates far more of its electricity from renewables than most countries - Uruguay produces more than 90% of its electricity from sustainable resources, like wind. And that, the government says, puts it in a good position to start producing green hydrogen.
Proponents of green hydrogen production in Uruguay say it will be good for the planet and the country's economy, but could it use too much water?
