First Minister Nicola Sturgeon is to unveil a new economic prospectus which will include a proposal to set up a £20billion investment fund if Scotland became independent.
She also told delegates in her speech at the SNP conference in Aberdeen yesterday that she would like to see the Granite City become the net-zero capital of the world.
Ms Sturgeon said her party would publish a paper next week which would make the economic case for independence. It is the third in a series of papers being published by the Scottish Government.
She said this would include plans for a fund which would deliver up to £20billion of investment within the first decade.
The SNP leader said money for this would come from oil revenues and by using borrowing powers.
Renewable energy resources
"It will set out how we can build a new, sustainable economy based on our massive renewable energy resources," Ms Sturgeon said.
"It will show how in an energy rich, independent Scotland, we can deliver lower prices and stronger security of supply."
The first minister also said that Aberdeen and the north-east is at the heart of the just transition to a net-zero future.
She added: "Since our late Queen - whose extraordinary life of service we have honoured in recent weeks - switched on the Forties pipeline in 1975, oil and gas has powered the Scottish economy.
"Her late Majesty, back then, inaugurated the oil and gas age.
"As we move now - in so many ways - into a new era, we have a duty to repay all those who work in that industry. A duty to support them into new jobs in green energy. An opportunity to usher in the new age of Scottish renewables.
Net-zero capital
"Aberdeen is the oil and gas capital of Europe. Let us resolve today to make it the net-zero capital of the world.
"That ambition led us to establish the £500million Just Transition Fund for this region. Today I can announce the first 22 projects have just been awarded funding of more than £50million. These projects will support the production of green hydrogen, the development of wave and tidal technology, and even pioneer the use of waste from whisky to recycle EV (electric vehicle) batteries.
Deputy First Minister John Swinney told the conference that Scotland's economy has many strengths, but when it comes to energy, it is truly a global power house.
He added: "With our plentiful resources of renewable energy, with our expertise in oil and gas, and the potential to be a world leader in emerging technologies like hydrogen and carbon capture, Scotland is well placed to provide much of Europe with access to clean energy.
"The transition to a net-zero future is a tremendous opportunity for Scotland, but it is also a considerable challenge. No more so than here in Aberdeen.
"This city faces an economic challenge on the scale faced by towns and cities across Scotland in the de-industrialisation of the 1980s.
Just transition
"Aberdeen's economy, like Scotland's, must transition from its reliance on oil and gas. But it has to be a just transition. One that takes our people, communities and businesses with us.
"That's why we are supporting that transition with an investment in this region of £500million over the next decade. Securing jobs and investment and ensuring Aberdeen's place as a centre of green energy expertise."
