Industrial energy use is responsible for 25% of all human carbon emissions. A significant percentage of that energy is used to generate heat for different industrial operations, including the manufacture of polymers and automotive batteries, according to a report by Interesting Engineering.
However, the introduction of brick toasters could make things better.
Rondo Energy, an Oakland-based startup, believes that this is a surefire opportunity to decarbonize more efficiently.
Rondo CEO John O'Donnell said in a statement with the Wharton Current podcast that this marks a "spectacular moment" in history.
"Where on a per unit energy cost basis, wind, and solar power are now cheaper than fuel. Not just cheaper than conventional electricity, but cheaper than fuel for heat in most of the world - headed for all the world."
Storing Inexpensive Renewable Energies
This basically indicates that the "green premium," which had been a hurdle for the renewable energy sector, is no longer an issue. The cost of renewable energy has reached its lowest point.
Rondo Energy creates "brick toasters" that can be used all day long and store inexpensive renewable energy as high-temperature heat. According to Rondo, industrial clients will start saving money right away compared to conventional fossil fuel burning procedures.
The system itself isn't particularly complex. Every toaster and hair dryer converts electricity into heat with 100% efficiency, according to O'Donnell. Rondo has created a technology that works like a toaster to heat up "blast stoves," which are used by the steel industry for cyclical heat storage.
These stoves are neither specialized nor particularly unique; they are just composed of regular clay bricks, occasionally with a little sand mixed in.
Once the chemical batteries have undergone numerous generations of complex recycling procedures in 40 or 50 years, the bricks will still be stored just as effectively, according to the company.
98% Efficiency
Rondo Energy also claims that it can extract the massive heat at a remarkable 98% efficiency, producing industrial heat storage that is approximately one-fifth the cost per unit of energy stored as any electrochemical battery and offers dirt-cheap heating storage.
The company is on its way to enhancing its production capabilities after Bill Gates' Breakthrough Ventures and other investors funded the technology.
Rondo said that its thermal energy storage technology is especially important for the shift to carbon neutrality in the cement industry.
The carbon-neutral, high-temperature heat from the kiln flue gases from the device can be used to make clinker and for the thermal activation of minerals and byproducts, reducing many emissions from burning fossil fuels.
