Ireland is aiming to have a sovereign wealth fund with assets of €100bn (£86bn) by the middle of the 2030s.
Finance Minister Michael McGrath outlined the plan as he delivered a budget on Tuesday.
The fund will be set up using some of the corporation tax windfall that Ireland has received from major global companies.
Mr McGrath said the Future Ireland Fund would be used to "protect living standards and public services".
There will be a second €14bn fund to protect infrastructure spending during economic downturns and invest in climate change measures.
Partial reforms to global tax regulation have had the unintended consequence of large US companies paying tax on much of their global profits in Ireland.
This has seen corporation tax receipts in Ireland balloon from just over €4bn (£3.5bn) in 2014, to more than €22bn (£19.3bn) last year.
The tax take is so large that the country is now able to run a substantial budget surplus.
However, the expectation is that at least some of this revenue is transitory, so it cannot be relied upon to fund permanent spending increases or tax cuts.
Therefore the government has decided to invest much of the money in the two funds.
Mr McGrath also announced a total budget package of €14bn.
Of that €6.4bn is core spending and tax measures with the balance going on one-off or temporary measures.
Those temporary measures include help with energy costs and a tax break for small landlords.
The infrastructure and climate fund was welcomed by Friends of the Earth.
Oisín Coghlan, chief executive of the environmental group said it was "a landmark development that can help underpin climate action and nature restoration for years to come".
"It means that whoever is in government after the next election will have funds to invest in getting off fossil fuels and reducing pollution, no matter what happens to tax receipts," he said.
"It's not everything we need to fund a fair and fast transition but it is a substantial down payment.
"It's equally significant that whoever is in government can only spend this money on climate and nature, increasing the chances of the policy consistency that households and businesses need to drive the transition to zero pollution."
Police presence
Security has been increased around the Oireachtas (Irish parliament) for the budget announcement after politicians and staff were unable to leave the grounds last month due to protests.
Over 200 gardaí (Irish police) have been deployed, including unarmed frontline uniform and plain clothed officers, and a number of streets in Dublin's city centre have been closed.
Gardaí have said there is a constitutional right to the freedom of assemble and of speech, but must be reasonable, proportionate and limited in its extent and duration.
