If you crack open a bottle of one thing - be it wine, water or tender drinks - over the festive season, there is a good probability the glass got here from the Encirc manufacturing unit in Cheshire.

Here, on the banks of the River Mersey, you'll find one of many world's largest glass factories. They take sand from Norfolk, soda ash created from the salt sitting beneath the Cheshire countryside and plenty of recycled glass and throw it into two of the largest glass furnaces on this planet.

There, within the furnace, at temperatures of round 1,600 levels centigrade, the sand melts and turns into a liquid river of molten glass. It is a chemical response people learnt hundreds of years in the past, however right here at Encirc it is carried out on a gargantuan scale.

This manufacturing unit alone produces two billion bottles and containers a yr, a quantity which is difficult to course of, till you observe that it contains round 40% of all of the wine bottles consumed within the UK.

That features a vital proportion of all of the New World wines we eat right here, by the best way. Mostly, the wine from Australia, California and Chile arrives not pre-bottled, however in massive luggage inside transport containers, that are then emptied into metallic vats at Encirc, from the place they're pumped into bottles made right here within the UK.

It's a rare web site - a spot which says quite a bit each about our urge for food for liquids (each alcoholic and never) and our capacity to show uncooked supplies into refined merchandise.

The wrestle to get to internet zero

But turning sand into glass is an enormously power intensive course of. Some of the warmth within the furnace might be created by electrical components which warmth the underside of this monumental oven. But glassmakers like Encirc say it is unimaginable to do what they do - making glass on an unlimited scale - with out blasting that furnace with a extremely popular flame.

At the second that flame is produced utilizing methane - pure fuel - with the upshot that this glassmaking facility produces slightly plenty of carbon dioxide. And even if you happen to might discover a approach of operating their furnace with no bare flame it could nonetheless be producing a sizeable quantity of CO2, since a few of it derives from the chemical response as sand turns into glass.

In brief, this glass manufacturing unit is a reasonably good illustration of how tough it's to get to internet zero. Much of the power use on this nation might be shifted from fossil fuels to inexperienced electrical energy - whether or not that is autos or residence heating. Sometimes the price can be excessive; typically in the long term, going inexperienced can be cheaper than the established order.

But for a handful of vital industries it's miles, far more durable. Glassmaking is a kind of industries. You can run small furnaces on electrical energy however not the massive ones it is advisable feed an enormous glass container manufacturing unit like this one.

All of which is why they're looking for one other various. The most blatant route to permit this plant to decarbonise is to switch these methane flames with hydrogen ones, after which to gather all of the CO2 popping out of the chimney and sequester it beneath the bottom.

And, because it occurs, the know-how is just about there. We know learn how to make hydrogen each from pure fuel and from electrical energy (the previous nonetheless entails some carbon emissions; the latter is extraordinarily costly, so these choices are not with out their points). We know learn how to seize carbon dioxide.

But there's a few issues which have at all times deterred companies like this from taking the leap. The first is that it hasn't made any financial sense. Capturing carbon is dear, so why do it when it is cheaper to pay for carbon credit and keep it up burning fuel?

Location, location, location

The second is that the infrastructure is not but there. Right now if you happen to collected carbon dioxide out of your chimney, there's nowhere to place it. Someone wants to put the pipes out to the depleted fuel reservoirs underneath the ocean the place we'd be capable to retailer it. That's additionally costly.

All of which brings us to one of many least mentioned, however arguably most vital subjects within the inexperienced power transition: clusters. In brief, if companies like this glassmaker are going to inexperienced it's much more prone to occur if they'll achieve this alongside different heavy business gamers.

Look on the geography of the UK's industries and the concept makes various sense. Many of the nation's largest polluters occur to be clustered comparatively close to one another on the coast. Alongside Encirc you may discover one of many nation's largest oil refineries, in addition to the Inovyn (a part of Ineos) chemical substances plant, to not point out a serious fuel energy station and, some miles additional away in North Wales, a cement producer.

All of those companies have massive power calls for. They would all profit both from carbon seize or hydrogen. Squint a bit bit into the long run and you'll envisage a world the place they share pipes each taking the carbon away and delivering the hydrogen.

How to make it occur?

But learn how to create these clusters? How to finance them? How to coordinate the companies that each one wish to make income whereas fulfilling their commitments to cut back or get rid of their carbon emissions?

It's a query nobody has but been in a position satisfactorily to reply, however whoever does may have that almost all valuable of issues: a blueprint about learn how to decarbonise the trickiest little bit of the world's carbon funds.

And guess what: it so occurs the UK is additional forward of most different international locations world wide in planning its blueprint for clusters. It now has detailed plans for learn how to fund, assemble and run a sequence of main clusters: one across the Encirc manufacturing unit (the Net Zero North West Cluster Plan), one other within the Tees Valley (Tees Valley Net Zero), in addition to plans for Scotland, for the Humber, for the Black Country and South Wales.

An space the place the UK is genuinely main

Thanks partly to authorities funding, which started in 2019, Britain's clusters experience is admired far and huge. While the US is extensively seen as having taken the lead on industrial decarbonisation, due to its monumental Inflation Reduction Act set of subsidies, Americans - and plenty of from Europe - have been usually visiting the UK to know learn how to do clusters.

There are many areas the place UK politicians declare (with out a lot foundation) to be world leaders, however right here is an space the place it does even have a world-beating proficiency. However, the federal government funding for clusters is coming to an finish in March, and people working listed here are nervous that this could possibly be one other space the place the nation squanders an early lead and shortly turns into a laggard.

While the cluster in Cheshire appears prone to turn out to be a bodily actuality, with corporations quickly laying the pipes that may join plans to hydrogen and carbon dioxide pipes, these within the Black Country and elsewhere are a lot much less superior.

It's one thing to ponder as you might have a drink over the festive season. It's tempting to imagine that Britain now not makes a lot of something any extra. However, go to crops just like the Encirc one, and also you realise that that could be very far off the mark.

And there is a prospect that this nation, which introduced the world the Industrial Revolution, could possibly be on the forefront of managing the inexperienced Industrial Revolution. In just a few years' time that tumbler could possibly be actually low carbon - perhaps in the end it could possibly be zero carbon. But it is going to take much more work - particularly on clusters - to make it a actuality.
