Can cargo ships run on hydrogen?

The European innovation project Flagships will deploy the world’s first commercial cargo transport vessel operating on hydrogen, plying the river Seine in Paris. Commercial operations are set to commence in 2021.

Are there any hydrogen powered ships?

The MF HYDRA is a zero-emission vessel operated by Norled and will be the world’s first vessel to be powered by liquid hydrogen. At more than 82m long with a capacity of up to 300 passengers and 80 cars, MF HYDRA operates at a service speed of about nine knots.

What is the most environment friendly fuel available that can be used by ships around the world?

This process is expensive, and currently just 0.1\% of hydrogen is made using it, but this is where the main hope lies for a climate-friendly shipping fuel. “Green hydrogen can be really emission-free on a full lifecycle basis,” says Marie Hubatova, a shipping emissions expert at the Environmental Defence Fund.

Is hydrogen a suitable replacement for fossil fuels?

Fuels produced from hydrogen can be used as straight replacements for oil and gas and can be low-carbon, if renewable electricity is used to produce these “e-fuels”. Using the electricity directly is efficient, but requires investment in new types of car and heating systems.

Why is it so expensive to ship hydrogen as a liquid?

Gaseous hydrogen is liquefied by cooling it to below −253°C (−423°F). Once hydrogen is liquefied it can be stored at the liquefaction plant in large insulated tanks. It takes energy to liquefy hydrogen—using today’s technology, liquefaction consumes more than 30\% of the energy content of the hydrogen and is expensive.

How are container ships powered?

Nearly all cargo ships use diesel combustion engines to turn the propellers, plus diesel generators that power onboard lighting systems and communications equipment. Many vessels still burn heavy bunker fuel, a viscous, carbon-intensive petroleum product that’s left from the crude oil refining process.

What type of fuel do container ships use?

Pollution. Due to its low cost, most large cargo vessels are powered by bunker fuel also known as Heavy Fuel Oil which contains higher sulphur levels than diesel.

How does a hydrogen fuel cell generate electricity?

Hydrogen fuel cells produce electricity by combining hydrogen and oxygen atoms. The hydrogen reacts with oxygen across an electrochemical cell similar to that of a battery to produce electricity, water, and small amounts of heat. Many different types of fuel cells are available for a wide range of applications.

Why do we not use hydrogen as a fuel?

Hydrogen fuel is hazardous because of the low ignition energy and high combustion energy of hydrogen, and because it tends to leak easily from tanks.

How do hydrogen powered ships work?

The ship uses up the H2 in operation when there is no wind. The H2 recharges the batteries and provides heat, then the batteries run all systems. With enough wind, the solar panels can instead recharge the batteries and make new H2 using desalinated water and electrolysis.
