LONDON - The government must pump tens of billions of public money into “gigafactories” that produce batteries for electric vehicles to secure the future of the UK car industry and create as many as 33,000 jobs, a new report has found.

As the world switches from petrol and diesel, the UK needs to scale up battery manufacturing capacity from the current 2 gigawatt-hours per year (GWh/a) to 80 by 2030 in order to safeguard up to 90,000 jobs in the automotive sector, found the report from think tank Common Wealth.

And the report, seen by The Independent, warned that the state will have to deliver the lion’s share of an estimated £100 billion investment over the next eight years or risk thousands of high-skilled jobs being “offshored” to other countries.

With the private sector committed to a total of £12 billion of investment and the government so far chipping in just £1 billion, the report concluded that an additional £10.9 billion is needed each year until 2030.

Ministers have previously indicated that they want the private sector to “lead the charge” towards mass ownership of zero-emission vehicles. But today’s report warned that leaving investment decisions to the market will expose the UK to the risk of offshoring capacity and jobs.

It recommended that at least half – and possibly the majority – of funds needed should come from the government and should be front-loaded to help Britain catch up with major EV producers like Germany and China.

This would allow the UK to secure a public equity stake in one of the big industrial growth sectors of the future, anchoring jobs in Britain and ensuring that the returns generated from investment are passed on to the taxpayer rather than private investors.

Investment on this scale could create 33,200 new jobs, said the report. And a controlling public equity stake would allow the government to direct production of lithium-ion batteries for buses and trams to help shift the balance towards clean public transport options.

As part of its plans to deliver net zero carbon emissions by 2050, the government will end the sale of new petrol and diesel cars by 2030, forcing a mass shift to electric models over the coming years.

But the UK currently has only one gigafactory, in Sunderland, which produces batteries totalling 2 GWh/a to Nissan. Planning permission has been given for a second plant in Sunderland and another in Coventry, while Britishvolt is constructing a battery factory in Blyth.

The report found that this leaves a “significant shortfall” in domestic battery manufacturing, with total estimated production from approved projects reaching just 45 GWh/a by 2030.

The automotive sector employs 797,300 people across the UK, including 156,400 in manufacturing, which generates £15.3 billion for the national economy.

Without an industrial strategy to secure a managed transition to electric vehicle production, some 90,000 jobs in the sector will be at risk by 2030, the report found.
