Injection of CO 2 began in a first-of-a-kind US Department of Energy–sponsored field trial of enhanced coalbed methane recovery with simultaneous CO2 sequestration in an unmineable coal seam. These wells have been producing coalbed methane and water since 2004. Monitoring the quality of groundwater and stream water.
Earlier, an existing coalbed methane well operated by El Paso Exploration & Production had been converted for CO 2 injection, and four wells drilled to monitor reservoir pressure, gas composition, water quality, and the CO 2 plume. The final phase, the development phase (2007–2018), will conduct large-volume carbon storage tests.
Optimized rock-fluid models will incorporate the seismic signatures of (1) saturation scales and free versus dissolved gas in a CO 2 -water mixture, (2) pore pressure changes, and (3) CO 2 -induced chemical changes to the host rock. WestVirginia University Research Corporation , Morgantown, W.V.
Surfactants produce bubbles, similar to soap in water, which raise the viscosity of a fluid, in this case CO 2. The NETL-RUA research team has evaluated CO 2 flows with surfactants that can increase the efficiency and efficacy of EOR with CO 2. Injected CO 2 with a higher viscosity will improve “sweep efficiency”—i.e.,
water management and treatment for power plant and CO 2 storage operations. The project has future applications for supercritical CO2 cycles in power plants, nuclear power, solar power and natural gas combined cycle units. Transitional Technology Development Awards. Lead organization. Description. Energy Industries of Ohio.
OK, well if you drive an EV in WestVirginia it is true, as that state produces roughly 94% of its electricity from coal power plants. But the problem with an example like that is that in 2020, WestVirginia only accounted for 0.1% times the number of EVs than households in WestVirginia.
The southwest province of Yunnan derives about 70 percent of its electricity from hydropower, slightly more than the percentage in Washington state, while Shandong, a coastal province in the east, derives about 90 percent of its electricity from coal, similar to WestVirginia. An EV operated in Yunnan emits about 60 percent less.
