SHUBox - Our 21st-century Steam Engine

Our solution refines century-old Organic Rankine Cycle (ORC) technology, which turns heat into electricity just as thermal energy powers a steam engine. We can harness heat from the ground, the sun, the air or biomass to generate energy. We refer to this combination of sustainable technologies and our ORC unit as our Smart Heat Utility Box (SHUBox). The SHUBOx converts 35% of thermal energy to power below 50°C. The core of earth is as hot as the surface of the sun. Geothermal energy has been harnessed for 100 years using deep drilling . Enhanced Geothermal Systems access shallow heat renewed by deep heat sources as well as stored solar power from the sun. To ensure there is always enough energy to power our SHUBox, we test the soil composition and water table to measure heat conductivity and tailor the ground probe before an installation is considered.

How it Works

Heat from renewable sources is harnessed to warm water to 50C via a heat pump - the same way a boiler heats water in a house. The hot water feeds a heat exchanger and brings it into contact with our proprietary fluid, which evaporates to steam at 50C. The fluid creates 250 times more steam than water, releasing much more energy. The steam moves a rotary motor and creates electricity. It's that simple.

Clean Power From Dirt

This means we can capture low-temperature heat from shallow depths in the ground to build small-scale power plants almost anywhere, with the same technology commonly used to heat and cool buildings. In an era defined by climate change, increasing demands for energy and reducing carbon emissions, this is an exciting opportunity to create clean, affordable power around the world.

The Age of Heat Farms

Wind and solar farms are commonplace depending on the climate in different parts of the world. Get ready for a new age of heat farms. According to the UK Department of Energy, one SHUBox, which is a 100kW unit, will power about 40 homes. SHUBoxes can be grouped together to form a 1MW ‘Clean Power Station’ (CPS). More can be added to create geothermal heat farms up to 10MW. Electricity generated by heat farms can stand alone as microgrids or feed into the national grid, which guarantees lucrative tariffs for long periods in some countries.

Groundbreaking Renewable Power

We're breaking new ground. Existing geothermal installations require deep drilling and extreme heat. We also use minimally invasive techniques to tap into the earth’s natural heat resources. Our micro-geothermal solution is more cost-effective and flexible, and less disruptive to the environment than traditional geothermal power, which requires deep drilling and extreme heat. Our mission is to create a network of interconnected microgrids and heat farms creating 24-hour clean energy around the globe.

Flexible Technology

The SHUBox works with any heat source and most locations. It’s compact - about the size of a standard shipping container - modular, expandable and mobile. All parts can be flown in by helicopter, making it perfect for remote areas. Solutions can be tailored for governments, power utilities or industry.
