The total amount of money being committed by these 20 countries - under Mission Innovation -- amount to USD 20 billion, about half of which would come from the US, White House officials said.
A formal announcement of the initiative is expected later in the day at a meeting attended by US President Barack Obama, Prime Minister Narendra Modi and French President Francois Hollande along with other leaders from the private and public sector, a White House official told reporters before Mr Obama left for Paris to attend the crucial climate change summit in Paris.
These additional resources will dramatically expand the new technologies that will define a future global power mix that is clean, affordable and reliable, the White House said.
"This is an effort designed to accelerate clean energy innovation and address global climate change, provide affordable clean energy to consumers with a special focus on the developing world in creating commercial opportunities for creating clean energy in developing countries," top Obama adviser Brian Deese told reporters.
Other participating countries include France, Germany, Australia, Brazil, Canada, Chile, Denmark, Indonesia, Italy, Japan, South Korea, Mexico, Norway, Saudi Arabia, Sweden, the UAE and the UK.
These 20 countries accounts for over 80 per cent of global clean energy R&D.
"One thing that we know clearly is that the investment in basic research in clean energy technologies needs to be connected to private capital that's willing to deploy against the most promising of those technologies and help bring them to scale," Mr Deese said.
Noting that Individual countries will focus on clean energy efforts that suit their needs, like energy efficiency or reducing hydrofluorocarbons, US Energy Secretary Ernest Moniz said in the US' increase in funding, about 15 per cent per year starting in 2017, would rely on Congress.
"There's a lot of support for innovation," he said. In addition to Mission Innovation, another 'Breakthrough Energy Coalition' will be launched simultaneously.
Spearheaded by Bill Gates, 'Breakthrough Energy Coalition' is a global group of private investors that will take the risks to allow the early stage energy companies that emerge from the research programmes of Mission Innovation countries to come out of the lab and into the marketplace.
