Cool Planet Wraps Up $60 Million Funding Round
Biomass to fuels firm Cool Planet has raised $60 million from venture backers in its fourth round of funding. Until now, two things had made Cool Planet unique in the biomass space – it attracted investment from Google Ventures, and its business model calls for small-scale, modular biorefineries.
Since venture backing for cellulosic fuels start-ups has been negligible lately, Cool Planet’s $60 million fund raise gives it a third unusual quality.
In some ways, Cool Planet is a bit like Khosla-backed KiOR – it relies on specialty catalysts to transform biomass (i.e. wood chips, agriculture waste) into drop-in, gasoline-like biofuels rather than ethanol like in most cellulosic fuel plants.
But Cool Planet sequesters the untransformed bits of biomass into what it calls biochar, which can be used as a soil enhancement in agriculture. Cool Planet did not invent the idea of biochar (which is sort of like charcoal), nor did it invent the idea of using it to boost soil productivity (through water and nutrient retention). But the carbon sequestration that biochar represents allows the company to advertise its fuel as carbon negative.
It’s not yet clear if farmers would adopt Cool Planet’s output, however. In fact, the company’s website says it is actively seeking partnerships to get this particular ball rolling. From the outside it is not clear to what degree profitability hinges on the sale of biochar.
Having a modular biorefinery sounds like an attractive concept, considering the module could be placed where biomass exists in significant quantities but would not be profitable to ship to a distant, huge biorefinery. Still, these facilities are not tiny; each “station” would produce 10 million gal per year of biofuel. And Cleantech Chemistry has not yet determined how the company plans to get the fuel output from these distributed outposts transported to a point of sale.
Cool Planet’s fund raising will be used in part to finalize engineering design for its first commercial facility as well as capital for construction in the Port of Alexandria, La. The company says it will be in operation before the end of 2014.
In addition to Google, Cool Planet has backing from North Bridge Venture Partners, Shea Ventures, BP, Energy Technology Ventures, and Excelon.
