PNNL team develops new low-cost method to convert captured CO2 to methane

Green Car Congress

By using a water-lean post-combustion capture solvent, (N-(2-ethoxyethyl)-3-morpholinopropan-1-amine) (2-EEMPA), they achieved a greater than 90% conversion of captured CO 2 to hydrocarbons—mostly methane—in the presence of a heterogenous Ru catalyst under relatively mild reaction conditions (170 °C and 2 pressure). Lopez, J.S.,

Surrey team developing direct-air-capture CO2 to methanol process

Green Car Congress

Its value could offset the cost of direct air capture. One of the biggest advantages to direct air capture technology is that it does not rely on extensive land and water use, unlike alternatives such as biomass. In 2020, the UK imported £145 million worth of methanol which amounts to 0.6-1.6

GWU team demonstrates highly scalable, low-cost process for making carbon nanotube wools directly from CO2

Green Car Congress

This synthesis consumes only CO 2 and electricity, and is constrained only by the cost of electricity. The process is constrained by the (low) cost of electricity. Schematic representation of an ocean-based solar thermal and photovoltaic field to drive both water purification and C2CNT splitting of CO 2 to useful products.

Alberta’s IETP awarding $33M in allowances to 5 projects to reduce oil sands CO2 and water use, improve recovery

Green Car Congress

Alberta’s Innovative Energy Technologies Program (IETP) is supporting 5 new pilot projects to reduce energy use, water use and CO 2 emissions in oil sands processing as well as improving the recovery of crude oil and bitumen in reserves that were once unrecoverable. Total project cost: $62,000,000. Total project cost: $18,200,000.

EPFL team develops low-cost catalyst for splitting CO2

Green Car Congress

The system uses the same catalyst for the cathode that reduces CO 2 to CO and for the anode that oxidizes water to oxygen through the oxygen evolution reaction. Using only Earth-abundant materials to catalyze both reactions, this design keeps the cost of the system low. The gases are separated with a bipolar membrane.

New diamine-appended MOFs can capture CO2 for half or less of the energy cost of current materials

Green Car Congress

Power plants that capture CO 2 today use an older technology whereby flue gases are bubbled through organic amines in water, where the carbon dioxide binds to amines. Because MOFs are solid, the process also saves the energy costs of heating the water in which amines are dissolved.

SRI developing process for co-gasification of methane and coal to produce liquid transportation fuels; negligible water consumption, no CO2

Green Car Congress

Researchers from SRI International (SRI) are developing a methane-and-coal-to-liquids process that consumes negligible amounts of water and does not generate carbon dioxide. Production cost of JP8 less than $3.00/gallon. Water consumption less than 235 kg/barrel. Capital cost less than $15,000/daily barrel.
