Prof. Charles Harvey is among the scientists who “warn that [carbon] removal technologies aren’t sophisticated enough nor coming online fast enough to reduce emissions to the level we need them to,” reports Tristram Korten for Fast Company.
Principal Research Scientist Emre Gençer speaks with The Independent reporter Louise Boyle about natural hydrogen and its potential as a future renewable energy source. “There is a ‘mismatch’ where natural hydrogen is being discovered and where it could be used, which would require massive investments in completely new infrastructure,” says Gençer. “I think it will be part of the solution but we need to take it with a grain of salt.”
MIT researchers have devised a new carbon capture system that “relies on the reaction between CO2 in flue gas and a fine mist of electrically charged particles,” reports Karmela Padavic-Callaghan for New Scientist. The researchers believe their design could be “95 per cent efficient at capturing carbon dioxide, while measuring less than 4 meters long,” Padavic-Callaghan notes. “Their analysis also showed that the approach would reduce capital costs of adding carbon capture to power plants by about 2.6 times compared with current technology.”
MIT researchers have analyzed the role of long-duration energy storage technologies and found that large storage systems have the potential to lower electricity prices in a carbon-free grid by up to 40%, writes Eric Roston for Bloomberg.
Martin LaMonica writes for The Boston Globe about how MIT researchers are creating a commercial prototype of a carbon capture device. Graduate student Aly Eltayeb explains that carbon capture could be useful in cutting carbon emissions, “especially if you can do something with that CO2 and stop treating it as a waste — and treat it as a valuable product.”
New research by Professor Daniel Rothman and postdoctoral associate Yossi Cohen has raised questions about the feasibility of carbon capture, reports Ken Silverstein for Forbes. The researchers found that “only a ‘small fraction’ of the carbon dioxide solidifies and turns into rock after it is injected 7,000 feet below the earth’s surface,” explains Silverstein.
MIT researchers have found that carbon sequestration may not be as effective at storing greenhouse gas emissions as originally thought, reports Christopher Martin for Bloomberg News. The researchers found that “much of the carbon dioxide will remain in its gaseous state, and may eventually escape into the atmosphere.”
