MIT study finds air quality co-benefits of US carbon policies can significantly offset costs, depending upon the policy

Green Car Congress

The human health benefits associated with improvements in air quality related to the reduction in greenhouse gas emissions improvements can offset 26–1,050% of the cost of US carbon policies, depending upon the type of policy, according to a new study by a team from MIT. times the cost of implementing a cap-and-trade program.

MIT Report Finds Natural Gas Has Significant Potential to Displace Coal, Reducing Greenhouse Gas Emissions; Role in Transportation More Limited

Green Car Congress

Natural gas will play a leading role in reducing greenhouse-gas emissions over the next several decades, largely by replacing older, inefficient coal plants with highly efficient combined-cycle gas generation, according to a major new interim report out from MIT.

Scientists have been steadily cutting these losses and ramping up the efficiency of photovoltaics, with the aim of bringing them to operational and economic parity with power plants that generate electricity via the spinning of turbines. A thermophotovoltaic (TPV) cell developed by engineers at MIT has eclipsed the 40-percent-efficiency mark.

DOE awards $7M to eight oxy-combustion coal technology projects; carbon capture, utilization and storage

Green Car Congress

The oxy-combustion process replaces the air used for combustion with a mixture of oxygen and recycled plant emissions (flue gas) and/or water for temperature control. The new selections announced today are part of a two-phase effort to evaluate and develop advanced oxy-combustion projects that yield cost-competitive options for CCUS.
