Brigham Young University scientist Larry Baxter believes that carbon sequestration will cause an increase in energy costs and a decrease in power plant efficiency. Despite those issues, it might be necessary to use the sequestration technology to fight global warming. Baxter himself has improved a coal gasification technology and possibly found a better sequestration technology. The new sequestration technology was developed while he was on leave in Denmark. It would reduce a power plant's efficiency by about 15 percent versus the 25 to 30 percent for the original technology. It would also be less expensive to install the technology. He is waiting to patent the technology. Baxter has also been working on gasification technology.
