The International Biochar Initiative (IBI)
Also... the marketing for Biochar could be something like "Biofuels are normally Food V Fuel. Biochar is Food AND Fuel!"
I see its most important function not being solving global warming (which is an EXCELLENT side effect) but creating sustainable agriculture in a post-oil world. When oil hits $500 a barrel, how many farmers are still going to have fuel and afford farming? Biochar reduces the energy required for farming by reducing the fertiliser inputs, and creates regional economic security and fuel security at least for the farming communities. It probably won't supply all us SUV driving suburbanites with the fuel we need in a post-oil world... so tough. We'll have to catch the bus, ride a bike, or maybe buy a smaller electric car. But if farming goes down, we're in a world of pain.
