'Sunfire' Converts Water & Air Into E-diesel in Dresden…!!!

Are You Kidding..? No…..! Germany's top luxury car-maker Audi has started working with this technology which can turn water & air into fuel aka E-diesel. This diesel fuel is made from water & carbon-dioxide in the air. It uses only natural energy sources such as solar & wind power. German Federal Minister of Education and Research Johanna Wanka became the first user to fill the e-diesel in her Audi A8.

The invention of the eco-diesel is a breakthrough in attaining the goal of sustainable alternative fuel for automotive engines. Thus, it will make a big impact on the contentious issue of climate change in the future. Automotive giant Audi seems to have taken the initiative to accomplish this goal by backing the e-diesel project.

Furthermore, Audi has set up a state-of-the-art plant in collaboration with a start-up company ‘Sunfire’. It has a capacity to produce about 160 liters a day of e-diesel. Audi named the e-diesel as ‘blue-crude’ which the company produced by using renewable energy sources in a three-stage process.

  • Stage 1

In the first stage, the company produces renewable energy from natural sources such as wind, solar and hydro-power. Using a process known as ‘reversible-electrolysis’, this energy then splits water into oxygen and pure hydrogen and releases the oxygen into the atmosphere.

H2O → Hydrogen + Oxygen↑

  • Stage 2

Stage 2 involves two chemical processes. Firstly, it extracts carbon-monoxide from carbon-dioxide. Then in the second process, it mixes the hydrogen with carbon monoxide.

CO2 → Carbon Monoxide + Oxygen↑

Then, it produces a crude liquid named the ‘blue-crude’ by the chemical reaction between hydrogen & Carbon-monoxide.
