Burning biomass has been seen as a green-ish option for power generation, as it is renewable, although scientists have warned the emissions caused by burning it may outweigh the benefits. Capturing those emissions, however, could solve that problem. In England, the biggest power station fueled by biomass in Europe is trialing a system that captures one ton of carbon dioxide from the plant each day. Ultimately, the plan is to produce so-called negative emissions—in other words, the power station would remove more greenhouse gases from the air than it produces. Incidentally, if you’re wondering what happens to the carbon dioxide after it’s captured, the power station has come up with a very British solution to a genuine British problem—it’s been talking to the beer industry about using the CO2 to keep its products fizzy.
