Switchgrass trials successful but still more expensive than coal

In Kentucky, switchgrass trials for biomass fuel production have been successful both in their production and in their 10% co-firing with coal, but costs remains the key issue. It still costs more to grow switchgrass than it does to buy coal. Until state mandates require plants to reduce their GHGs, forcing them to switch to biomass rather than burn coal, the feedstock that can be grown successfully on marginal land is likely to only find a market as forage for cattle.
