ResHydro announced it would work through a partnership with the Scottish University of Strathclyde to develop a hydrokinetic device for eventual commercialization.
"Scotland has an incredible wealth of energy resources and is leading the way in the development of marine renewables technology," Salmond said. "ResHydro's decision to invest in Scotland and work in partnership with one of our leading universities to further their research and development plans is testament to that."
New hydrokinetic projects are moving toward commercialization, though there are only 40 sites in the world that have tidal variances great enough to produce electricity.
Scotland has one of the most ambitious low-carbon strategies in the world. Scotland's renewable energy made up 35 percent of the total renewable energy generation in the United Kingdom last year.
ResHydro's deal follows Salmond's visit to the United States, here he worked to attract foreign investments.
