Weyerhaeuser, one of the workshop hosts has a partnership with Chevron called Catchlight whose aim is to develop integrated biomass systems. One of their innovative ideas is to intercrop switchgrass with pine. The pine will be grown to rotation for sawtimber, while the switchgrass is annually harvested for biomass. They have worked on it for a few years but nothing is operational or scalable yet. Many issues. Can it work efficiently. Here are some pictures of the intercropping system.
