Khepra's technology is unique but simple - it harnesses a natural phenomenon called cavitation. Cavitation is the formation of tiny bubbles that grow until they implode - high temperatures and pressures. Cavitation is produced by high frequency sound waves in liquid amplified by focusing the sound to a point. This creates significant, high efficiency energy transfer in a continuous flow chemical reactor.

Khepra's chemical reactor is a high throughput, continuous flow system that uses high energy, focused ultrasound to break down plastics, polymers, and biological molecules at the chemical and physical level. This reactor produces the hydrocarbons commonly found in fossil fuels from the world's toughest wastes - ranging from mixed plastics to cellulose. These hydrocarbons can be used to make energy, new plastics, and materials that go into the products we use everyday.

Since the reactor works by generating ultrasonic waves, we can generate these hydrocarbons without the use of fossil fuels by powering the system with renewable energy. Ultrasound can be used to supply energy to the system instantaneously, making it a viable method of storing renewable energy that is produced in excess, when prices can become low if not negative. The resulting fuel can be used to produce electricity in conjunction with wind and solar generation.

Why not batteries?

Batteries and our system are not mutually exclusive, however batteries can't meet grid-scale demand on their own. The mining of lithium is an incredibly dirty process. At the end of their lifetimes, batteries must be recycled, a process that is expensive and energy intensive. Fuel production facilities aren't limited in this way. They work better for large scale applications. Storing energy in batteries limits the radius where electricity can be supplied. Fuel has pre-existing networks which we can tap into for an efficient and clean energy capable of global transmission.

What are the impacts?

Producing fuel from waste and electricity is a net zero process and can provide carbon offsets to plastics recycling and agriculture. We would be making a massive dent in reducing both oil drilling and consumer waste. Additionally, producing fuel from renewable electricity means that clean fuel can be shipped anywhere in the world, regardless of where it was produced. Icelandic geothermal can power Beijing!

What can we power?

With the world electrifying, it is important to find a solution to power both existing infrastructure and new electrified projects. Renewable fuels can replace fossil fuels in existing power plants, for when the wind doesn't blow and the sun doesn't shine. We are part of a solution for fast, efficient, and low-cost energy with massive scalability and minimal environmental impact.
