The researchers and engineers at ETH Zurich have developed innovative processes that make it possible to extract CO 2 from the atmosphere and, together with water and with the help of concentrated sunlight, convert it into a synthesis gas that can be used to produce jet fuel.

Findings by MIT researchers could help advance the commercialization of supercritical water technology for the desulfurization and upgrading of high-sulfur crude oil into high-value, cleaner fuels such as gasoline without using hydrogen—a major change in refining technology that would reduce costs, energy use, and CO 2 emissions.

Through a recent modeling experiment, a team of NASA-funded researchers have found that future concentrations of carbon dioxide and ozone in the atmosphere and of nitrogen in the soil are likely to have an important but overlooked effect on the cycling of water from sky to land to waterways.

Geely’s CRI investment and work with renewable methanol is similar to the approach Audi is taking with its own e-fuels projects—producing very low carbon liquid or gaseous fuels using only renewable energy, water and CO 2. Earlier post.). Earlier post.)

Between five and ten percent of the water injected in these systems is lost as it travels through the pore spaces. As this happens, more water must be added, perhaps from municipal sources that have little to spare. Their work has shown that supercritical CO 2 is better than water at mining heat from the subsurface.

The direct fuel cell produces electricity, with water and CO 2 as byproducts of the oxidation of the liquid fuel in the fuel cell. Although there are “ open issues ” with longevity, the SOEC devices have “ good performance ” in splitting water, the authors note. The syngas is then in turn converted into liquid fuels (e.g., Zhan et al.

Researchers at Oregon State University have demonstrated the gasification of water-soluble biomass constituents in supercritical water in a microchannel reactor under isothermal, continuous flow condition at short residence times to produce a hydrogen-rich gas.
