DOE selects 2 projects to demonstrate feasibility of enhanced water recovery; producing usable water from CO2 storage sites

Green Car Congress

The US Department of Energy (DOE) has selected two projects that will test emerging enhanced water recovery (EWR) technologies for their potential to produce useable water from CO 2 storage sites. The novel management strategy designed for this project combines “active” water extraction from one well with “passive” pressure relief using another well, using an adaptive process.

Geely invests in Carbon Recycling Intl.; vehicles fueled by methanol from CO2, water and renewable energy

Green Car Congress

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. Its first commercial-scale production plant obtains carbon dioxide from gas emissions from a geothermal power plant and hydrogen via electrolysis of water using renewable sources of energy from the Icelandic power grid (from hydro, geothermal and wind sources).
