Ampd Enertainer

Country: Hong Kong, China

The construction industry is difficult to decarbonise and is one of the biggest drivers of air pollution. Ampd Energy has revolutionised the way we power construction.

Their Story

Today, construction is responsible for almost 11 percent of the world’s energy-related CO2 emissions, in part because building sites require a lot of power and often need mobile energy sources. These are typically fossil-fuel engines which emit harmful pollutants, including CO2, carbon monoxide, nitrogen oxides and particulate matter.

Enter Hong Kong entrepreneur Brandon Ng and his team at Ampd Energy.

Ampd’s flagship product is called the Enertainer. The Enertainer is an all-electric battery energy storage system designed specifically to power construction sites without the need for direct use of fossil fuels. This reduces or eliminates altogether, the harmful pollution which would have been produced by fossil-fuel engines used on construction sites. The system can power any type of electrical equipment — cranes, hoists, welders, barbenders and more — with its lithium-ion batteries, which are similar to those used in electric cars.

Every switch from a diesel generator to an Enertainer curbs 130 tonnes of CO2 a year, in addition to removing the equivalent of three hundred cars of air pollution. Currently used by nearly 100 construction projects, Ampd’s products have saved more than 17,000 tonnes of carbon pollution to date. They even reduce running costs by up to 85 percent and are safer and quieter for both workers and local communities.

Step by step, Ampd is turning construction sites green.
