Cool Planet’s approach to producing renewable energy will have a positive impact for today’s farmers and the agricultural industry. As part of Cool Planet’s carbon negative fuel cycle comes a unique form of carbon known as biochar. Biochar is highly porous and has beneficial water and nutrient retaining capabilities, making it an ideal soil enhancer used for improving agriculture. Cool Planet research has shown as much as 50 percent increase in plant growth in marginal soil using minimal water.
