The 50-kW pilot reactor, installed in Spain, uses heat from a concentrating solar tower to drive a thermochemical redox cycle This pilot plant runs on concentrating solar thermal energy.

In this paradigm, aerobic respiration, denitrification, fermentation and sulfate reduction proceed in a thermodynamically determined order, known as the ‘redox tower’. Here, we investigated ...

"This solar tower fuel plant was operated with a setup ... and developing methods to recover the heat released during the redox cycles. This work is supported by Swiss State Secretariat for ...

First it captures the ambient air to extract CO2 and H2O before a solar redox unit converts the CO2 ... If the construction materials of the solar tower plant are created using renewable energy ...
