This Week in Cleantech is a weekly podcast covering the most impactful stories in clean energy and climate featuring Paul Gerke of Factor This and Tigercomm’s Mike Casey.

This week's episode features special guest Clara Hudson from the Wall Street Journal, who breaks down Heineken's plan to use a renewable-powered heat battery to release steam for its beer brewing in Portugal.

This week’s “Cleantechers of the Week” are Tim Shepherd and Sylvain Marseille from Pelton Shepherd Industries, which makes Nutri Ice – ice packs that you can use to feed plants. It is the only truly compostable gel pack and offers the same performance as a regular gel pack. Congratulations Tim and Sylvain!
