Safety diary 2025 National Grid Transporting NGED to Net Zero Why are we electrifying our fleet In addition to the UK legal requirement for the nation to be Net Zero for carbon emissions by 2025 The International Panel on Climate Change IPPC has concluded that humanity needs to reduce carbon emissions by at least 50 by the end of this decade In the UK transport makes up around a quarter of our emissions while in NGED transport and fuel combustion make up almost two thirds of our carbon footprint So we simply cannot reduce our carbon footprint and become a net zero organisation without decarbonising transport Why electric vehicles While technologies like synthetic fuels and hydrogen fuel cells are likely to play an important part in transport sectors where batteries are impractical shipping aviation heavy plant etc battery electric vehicles BEVs are the only available technology that can be deployed quickly enough for us to have the impact that is needed While alternatives to cars and vans like walking cycling and public transport are also essential are teams will need cars vans and other fleet vehicles for a long time to come BEVs are also becoming quickly cheaper with improving range and a longer life as shown below A cleaner vehicle for National Grid Electric vehicles often receive criticism for the larger carbon footprint associated with their manufacture compared to internal combust engine vehicles ICE and understandably so It s true if an EV is manufactured in a facility powered by fossil In the last decade batteries have become cheaper longer lasting and able to carry more energy

National Grid 2025 Safety diary fuels then charged with electricity generated by fossil fuels it could take some vehicles up to 60 000 miles of driving to pay back that carbon debt However as renewables play an ever greater role is electricity generation both in the UK and across the globe it will be possible to both manufacture and charge an EV using renewable energy When this is the case then the carbon footprint of an EV could be zero And this may not be too far away at least one EV manufacturer currently has a target to make a Net Zero EV by 2030 As customers we can further the impact the carbon footprint of our EV charging and energy use by choosing to charge vehicles and use high demand appliances when electricity is its cleanest thanks to apps like National Grid s When To Plug In app Checking apps apps like National Grid s When to Plug In can help EV charging get even cleaner by charging when energy is clean But aren t EV batteries wasteful and impossible to recycle No in fact developments in battery component extraction mean processing centres can extract 98 of battery materials for recycling or reuse Arguments that Charging an EV results in around 70 less carbon emissions than it did a decade ago As we help the grid get cleaner we help EVs get cleaner electric vehicle batteries either can t be recycled or are difficult to recycle and ultimately end up in landfill are quite simply untrue EVs may be okay for short trips but aren t they impractical for long trips and operational duties The sweet spot for the range of an EV is between 200 and 300 miles This gives the optimal balance between cost battery size and range Whether at work or for personal use most people don t need a range of more than this after the time it takes to drive this distance most of us need a pit stop anyway So it s really not about range it s about access to good reliable fit for purpose charging infrastructure so whether it s on a road trip with the family or a busy day on standby we can charge quickly while we re having a rest taking a break or talking to colleagues Across the UK charging infrastructure is accelerating at a rapid rate as can be seen using apps such as ZapMap while in NGED we will soon have access to one of the largest private charging networks in the UK

Safety diary Does the electricity grid have enough capacity for charging EVs Peak demand for electricity in recent years in the UK was for 62GW in 2002 Since then the nation s peak demand has fallen by roughly 16 due to improvements in energy efficiency Even if we all switched to EVs overnight we National Grid ESO estimate demand would only increase by around 10 Plus a significant amount of electricity is used to refine oil for petrol and diesel Experts estimate that refining 1 gallon of petrol would use around 4 5kWh of electricity so as we start to use less petrol or diesel cars some of that electricity capacity could become available Of course as energy use changes so our network will have to change and adapt with it and as more and more cars are connected in areas that previously didn t have much demand we ll have to both get smarter around network management and also in some cases reinforce our network That s not just the case for EVs but for heating and the connection of renewable generation to our network So yes the energy transition will require new ways of doing things of thinking and of working But for the future of humanity we have to change and society cannot make these changes without our network and our staff being up to the challenge One thing is for sure the future will be exciting challenging and there will be no shortage of work And 2024 is just the beginning 2025 National Grid
