The UK's ambition to reach net-zero emissions by 2050 has meant many industries try to adopt greener technologies. Yet for many industrial businesses, especially those in such power-hungry sectors as steel, glass, and ceramics, the route toward greener alternatives has been far from easy.
One of the major issues has been the delayed connection to the National Grid for electric furnaces, which is very important in trying to cut carbon emissions. There has recently been news that it might not be available until 2032, dimming green ambitions.
The role of electric furnaces in green industrial transformation
Electric furnaces are one of the main technologies to help industries reduce their carbon footprint.
Conventionally, furnaces used in industries such as steel and glass manufacture are fired by fossil fuels, with coal, oil, or gas being the predominant fuels. These processes thus have a high contribution to the UK's overall carbon emissions.
Therefore, electric furnaces powered by renewable energy sources offer a cleaner alternative.
This would not only reduce the level of emissions but may also further increase energy efficiency and provide lower operating costs in the long run. For the industries that have faced increasing pressure from government regulations, consumers, and the global markets to reduce their environmental impact, electric furnaces were considered a major step toward the decarbonisation of heavy industry.
A disappointing setback: delays up to 2032
While this is a very important technology, the ability of industrial businesses to apply it has hit one key stumbling block: they cannot connect electric furnaces to the National Grid.
It's estimated that many large-scale manufacturers will not be able to achieve the required grid capacity until 2032. The feared derailment of this near decade-long setback may seriously disrupt the momentum many businesses have been developing in their green transition plans.
Most of these delays are caused by infrastructure issues, particularly in the UK's National Grid. The current grid was designed well before the increasing need for electricity as more industries began converting to electric power. Upgrades to increase the grid's capacity, especially in highly concentrated areas of industrial activity, have been very slow. The government and National Grid have acknowledged that this requires major investments in new infrastructure, but these projects take time to complete—resulting in frustration for those businesses ready to adopt the technology for electric furnaces.
The Ripple Effect: financial and environmental impacts
Financial stress on enterprises
Many businesses have already invested in the early stages of the transition to electric furnaces, ordering new equipment, securing financing, and setting ambitious sustainability targets in line with the wider UK net-zero goals.
With delays in grid connections, businesses are being put at risk of either having to leave expensive electric furnace systems sitting idle or taking additional costs to keep outdated fossil-fuel systems for longer than expected.
This delay further extends to the larger industrial supply chain. Industries dependent on steel, glass, or ceramics may need to bear increased prices because of the costs of manufacturers holding onto older, less efficient systems. This economic ripple might reach the construction, automotive, and electronic sectors, among others.
Environmental setback
Perhaps the most worrying of the effects has been the environmental setback. Industrial businesses that were supposed to decrease their carbon footprint by adopting electric furnaces will now have to depend on carbon-intensive energy sources for longer than expected.
At a time when temperatures are rising in the world and the call for climate action is being raised, overdependence on fossil fuels proves very challenging to the UK's commitment to climate.
The delay is putting at risk the capability of the country to achieve its interim climate targets in 2030, as heavy industry comprises approximately 16% of the UK's total greenhouse gas emissions. If its industrial businesses can't make that switch on time, it might compromise the ambitions of this government to cut emissions by 68% by 2030 and reach net zero by 2050.
What can be done?
While this scenario is undeniably quite challenging, various mitigations are possible for such delays in the following ways:
Speedier upgrades of the grid
This requires that the UK government and National Grid expedite infrastructure projects, improving the grid's capacity available to industrial users. Streamlined approvals coupled with increased funding can cut down on the timeline of upgrade projects, thus allowing access to electric furnace connections earlier.
Incentivising green solutions
While waiting for this access to the grid, the government can incentivise industries for interim measures that reduce emissions. This may include hybrid systems operating on both fossil fuels and electricity, or investment in technologies for carbon capture and storage.
Decentralised power generation
Companies in the industry can also consider the local production of renewable energy independently, such as solar or wind power. This requires huge investments at the front end but can be one of the available options in a case where companies do not want to wait until 2032, by which year access to the grid is expected to become widely possible.
Government support
Companies will further require more financial support from the government in sustaining losses for maintaining old systems and preparing for greener alternatives. These could be in the form of tax relief grants or low-interest loans for energy efficiency and sustainability projects.
This delay in connecting electric furnaces to the UK's National Grid serves as a very stark reminder that not every transition to green technology may be as seamless as it seems. Yes, industry is, rightly, embracing cleaner ways of using energy; however, there are substantial constraints on infrastructure.
Unless joined-up action is taken to rectify these delays and further support industrial businesses in their efforts towards greening, the UK is at risk of further falling behind ambitious climate targets.
Until then, the road to net zero remains bumpy for some of the UK's most vital industries. Until then, it will be necessary to improvise creatively for manufacturers and stakeholders to accept new times or to argue for faster progress toward the critical infrastructure that can enable the go-green transition.
