Each year millions of tons of waste cold from liquid natural gas (LNG) are discarded– but innovative tech and new business models could transform this untapped resource into emission-free power and cooling on-demand and provide electricity to the grid.

To help make this a reality, IFC’s award-winning TechEmerge program has convened a group of internationally renowned clean energy and sustainable cooling experts to explore and advise on the technical and commercial potential of LNG waste cold recovery.

Market Context


New technologies & business models can increase the efficiency of waste cold recovery processes

~$50+ bn

Potential investment opportunity of harnessing waste cold from LNG, by 2030

In recent decades, significant progress has been made in recovering waste heat produced during the operation of power plants, incinerators, cooling towers, and other thermodynamic processes. Now attention is shifting to the enormous potential to capture waste cold released during the LNG regasification process and transforming this into emission-free energy and cooling.

Research indicates that innovative technologies and business models could increase the efficiency of LNG waste cold recovery processes to 60-80 percent. Harnessing this resource could generate more than $50 a ton in economic and social benefits. By 2030, this would represent an investment opportunity of approximately $50+ billion. 

Beyond creating new markets, efficiently harnessing waste cold could strengthen energy access for underserved communities, while also reducing the environmental impact and carbon footprint of the LNG sector.
