to keep heating and electricity supplies  running this winter and next.

We're heading toward the only fixed LNG terminal in Greece, which receives, stores and turns

this critical fuel back into gas. That gas is then piped around the country.

Natural gas is often found  in secluded, far-flung areas.

But its portability in the liquid form means  that it can be shipped anywhere in the world.

Liquefied natural gas, or LNG, can be used  in the power sector to make electricity

and in the industrial sector to make fertilizers and petrochemicals.

It can also be used for cooking and to heat homes.

But how is LNG made?

First, natural gas is extracted from the ground.  It's then cleaned up and sent to a plant,

where it's cooled to approximately minus 260 degrees Fahrenheit

or minus 160 degrees Celsius.

By turning the gas into a liquid,  its volume is 600 times smaller

allowing it to be safely and easily  transported on LNG carriers.

Once the liquid arrives at its  destination, it's turned back into gas.

Aristotelis Nastos is the plant manager  at the Revithoussa LNG Terminal,

the only LNG import terminal in Greece.

This is the gasification process. The LNG is in  minus 160 and must be in positive temperature.

So, we had the heat exchangers with seawater, we take the thermal energy from the seawater,

which is 20 degrees normally, and we need  this thermal energy to gasify the LNG.

What happens after the regasification  process? Where does the gas go?

The gas goes to the grid, in the pressure about  from 50 to 60 Bars, and comes all over Greece,

and also the countries near Greece, Bulgaria and other European countries”

There are two main types of LNG import facilities,

Fixed terminals and ships called Floating Storage Regasification Units or FSRUs.

Fixed terminals are very costly and take years to build, unlike FSRUs,

which can be leased for a fixed number of  years and are moored near a pipeline.

The downside to the more flexible FSRUs is that  they cannot process large quantities of LNG,

unlike the fixed terminals on land.

The biggest exporters of LNG are Australia, Qatar and the United States.

Since Russia's invasion of Ukraine, the U.S.

has stepped up its supply efforts to Europe,  doubling its LNG exports to the continent.

The U.S. is set to be the world's  biggest LNG exporter.

Before the invasion of Ukraine, Europe was  heavily reliant on Russian pipeline gas.

As Russian supplies started dwindling,

Europe had to act fast and pivot  away from Russian gas to LNG.

What has it been like here in  the current energy crisis?

How has your regular business activity changed?

Normally, we receive four  to five vessels per month.

And now with the crisis, we are  receiving 10 vessels per month.

Also, the regasification rate is doubled,  normally is five to 800 cubic meters per hour 

and now we are increasing up to the maximum which is 1,400 cubic meters per hour.

The fresh supply of LNG allowed Europe to successfully fill its gas storage sites

to 95% ahead of the 2022 winter season.

The influx of LNG to Europe has meant

that storage facilities on the  continent are filled to the brim.

It's a happy problem, but it means that Europe is now scrambling for new capacity.

While Europe's LNG infrastructure capacity is  significant, access is uneven across countries.

France, Spain, Italy and the U.K. all have their own fixed terminals,

while countries like Germany have none.  Germany, Europe's largest gas importer,

was instead reliant on Russian pipeline gas.

Without it, Germany and others had to hire  floating terminals to tide through the crisis.

Plans are afoot to build more than a dozen more  LNG import facilities over the coming years.

I spoke to Greece's Environment  and Energy Minister Kostas Skrekas.

How would you say Europe is  doing in terms of its efforts 

to replace those Russian  pipeline gas flows with LNG?

Europe is trying very hard. Greece is going to be

transformed to the main entrance gate, import gate of LNG for the cell system in Europe.

But it takes time for those infrastructure projects to be completed.

Greece currently has one terminal  here on Revithoussa that can receive LNG,

temporarily store, regasify and supply it to the country's network of pipelines.

A new Floating Storage Unit has recently been added to the

existing facilities at Revithoussa which will increase its storage capacity by 70%.

Unlike an FSRU which has regasification capabilities, an FSU can only store the LNG in its liquid form

until there's space at the nearby terminal to begin the regasification process.

We're seeing a lot of import terminals coming  online over the next couple of months and years, 

to enable Europe to import more LNG,  particularly from the United States.

How flexible is this new LNG import  capacity that Europe is investing in?

Many of those terminals are being  charted for a period of five years.

So once a period of five years is over,  and they can either be rechartered

for a shorter period of time, or they can float elsewhere and  

go to somewhere else in the world.

While all this new capacity in the EU should help ease storage bottlenecks,

supply of LNG is the bigger concern.

As business activity starts to recover  in parts of Asia, especially China,

stiff competition for LNG  could lead to higher prices.

For now, Europe looks likely to avert a worst-case  scenario this winter with muted demand from Asia

and a milder than expected start to the season.  However, experts are warning against complacency.

Maria Rita Galli is the CEO of DESFA, Greece's  natural gas transmission system operator.

How worried are you about Europe's energy  situation, either this winter or next?

The situation for this winter is certainly in a  much stable situation because more than 90% of

the total storage capacity on Europe has been filled. The difficulty will be for the next summer

to replace the gas that will be  utilized during the winter.

So the key question for next year is,  what will the reopening in China mean

for China's LNG demand going forward?  And will that pull gas away from Europe?

LNG is also not a long-term solution to Europe's  energy problems, given its green energy ambitions.

Prior to Russia's invasion of Ukraine, Germany  aimed to abandon fossil-fueled power by 2035.

For now, LNG is seen as an important fuel to  get Europe through the current energy crisis.

And it doesn't hurt that some of Europe's new permanent LNG infrastructure

can be converted to work with  renewable resources in the future.

Over the longer term, we will be moving more  towards a renewable environment and gas

is a great bridging fuel because obviously the  sun doesn't shine and the wind doesn't flow

all of the time. So, gas is a backup  fuel for when those situations arise.

Do you see the risk that this investment into LNG in Greece and across many countries

in Europe as undermining efforts  to power the green transition?

Nobody is planning infrastructure that is going  finally all projects that are going to end up

to be stranded assets. The LNG terminals

could be used in the future for hydrogen maybe.

We have to plan projects in a very well-balanced manner.
