Shipping companies have billions invested in fleets that were built to last decades. Now, the US is calling for zero emissions by 2050, and the EU is raising the cost of fossil fuel use.

Astronomers have long known where water is first formed in the universe and how it ends up on planets, asteroids and comets. A recent discovery has finally answered what happens in between.
The Huc enzyme can split hydrogen molecules to make electricity, raising the possibility of small devices that run on air.
Japan’s Fukushima Daiichi Nuclear Power Plant is set to release radioactive wastewater into the Pacific Ocean – but the cause for concern is minimal.
Without energy market reform, expensive gas will have few upsides.
A lack of clarity over certain issues risks preventing the shipping industry’s energy transition from taking off.
Hydrogen cars were heralded as an avenue towards universal green motoring, but progress has stalled in recent years.
To export hydrogen through the new pipeline, Spain and Portugal would first have to be able to produce enough to meet domestic demand and have surpluses to send to France.
A new energy deal between Canada and Germany could revitalize the Port of Churchill in Manitoba by increasing ammonia export traffic.
China is committed to becoming carbon neutral before 2060 – and producing green hydrogen is key to the plan.
From pulling carbon dioxide out of the air to turning water into fuel, innovators are developing new technologies and pairing existing ones to help slow global warming.
Electricity, not what the EU calls ‘renewable gases’, offer the fastest route to decarbonising heating.
Australia could use about 7,000 terawatt-hours of solar and wind generation per annum to make a sizeable contribution to cutting global emissions – about 27 times its current electricity output.
Any climate gains from Japan’s shift will be wiped out entirely unless Australia moves to zero-emissions ammonia production.
We need to rapidly reduce global emissions before 2030. Developing hydrogen for low-emissions road transport won’t happen fast enough.
A billion-year-old ‘hydrogen economy’ in the frozen soil of Antarctica provides bacteria with energy, water, and the carbon that makes up their bodies.
The UK prime minister has been setting out ambitions to be a world leader in the coming hydrogen economy.
There are vast quantities of water ice on the moon that represent the potential for extraction and use in rocket fuel. But there are no practical reasons to mine this water.
The UK government claims hydrogen could meet one-third of the country’s energy demand by 2050.
Hydrogen fuel derived from natural gas may be worse for the climate than the fossil fuel even with carbon capture and storage.
