To protect fish, Bill Gates invests in more environmentally friendly hydropower technology

Breakthrough Energy Ventures, founded by Microsoft founder and billionaire Bill Gates, has approved a $ 11 million investment in Natel Energy. Natel Energy ’s turbines use water as a renewable energy source.

Bill Gates announced support for a new hydropower technology that claims to have changed the way water is used in renewable energy. Another company founded by Gates, Breakthrough Energy Ventures, has partnered with Schneider Electric to invest $ 11 million in Natel Energy. Natell Energy, together with its own "Restoration Hydro Turbine" (RHT), makes industrial hydropower plants more efficient and reduces the impact on fish and other environmental factors.

It is said that this power generation system for rivers is 20% cheaper than the commonly used turbines. This is another feature that distinguishes the project from other turbines and increases the chances of its use. In addition, the company has increased the chance to attract customers, claiming that it is safer for fish.

An RHT pilot facility was established:

It is understood that a pilot RHT facility has been established in Maine and is currently in operation. The facility meets the power needs of restaurants and schools, and even delivers a lot of power to the grid.

"Breakthrough Energy Investment Corporation" told Natell Energy Corporation: "For a long time, hydropower has been regarded as the best renewable energy source. The problems facing us are only high capital requirements and harm to wildlife. The patented hydraulic turbine was patented by Natel, which solved these two problems intelligently. "One of these two problems is related to the cost of the turbine, and the other is not harmful to the environment. "

According to the statement, this system can be used to strengthen existing facilities, and can also be developed and used in different places. This means that Nutl may change the way water is used as a renewable energy source. At this time, the company stated that the $ 11 million investment will be used for the further development of RHT.


The small number of blades reduces the possibility of fish impact. The blunt, sloping leading edge causes the fish to deviate from the sheet, thereby reducing the possibility of direct impact. The tilted head reduces the severity of the blow, increases the speed of the runner, and reduces the cost of the generator. The carefully designed runner efficiency is the same as the traditional propeller blade. Variable speed and variable gates can achieve double-adjusted efficiency curve. Although the diameter of the runner is 1M-3M, the design of the turbine can make the survival rate of fish (such as salmon) less than 200 mm in length pass more than 99%.
