A novel class of materials that enable a safer, cheaper, and more energy-efficient process for removing greenhouse gas from power plant emissions has been developed by a multi-institution team of researchers. The approach could be an important advance in carbon capture and sequestration (CCS).
Clean technology support can to some extent make up for weak CO2 pricing and hence help keep the two degrees target within reach, a new study shows. Even if the world climate summit in Paris later this year is successful in striking a climate deal, it might not bring about sharp greenhouse-gas cuts in the near-term. However, emission targets could be strengthened by complementary policies.
One of the major drawbacks of carbon-fueled battery cells is the intrinsic presence of CO2, which impedes CO oxidation and, therefore, lowers the energy density of the cell. Researchers describe a novel dual-phase ion-conducting ceramic membrane that is absolutely gas-tight but highly permeable for CO2.
Two new reports from the Energy Department's National Renewable Energy Laboratory (NREL) examine the economic options customers face when deciding how to finance commercial or residential solar energy systems. NREL analysts found that businesses that use low-cost financing to purchase a photovoltaic (PV) system and homeowners who use solar-specific loans can save up to 30 percent compared with consumers who lease a PV system through a conventional third-party owner.
