A UK team has begun work on what the BBC reports is the world’s first highly compressed air storage unit.
The 50-megawatt boiler will take excess power from wind farms and use it to store ordinary air at such high pressures that it will become liquid. Then, during peak demand periods, they will heat the stored air and use it to power a turbine that pumps electricity back to the grid.
The system was designed by Peter Dearman, a self-taught inventor in Hertfordshire, and was taken to commercial scale with a £ 10 million grant from the British government.
Inventor Peter Dearman told the BBC that the system is between 60 and 70% efficient. He predicted that they would be able to easily scale the system by adding more tank volume. “Batteries are great for short-term storage,” Dearman said. “But they are too expensive to make long-term energy storage. That’s where the liquid air comes in, “he added.
Peter Dearman also developed a machine that works on principles similar to liquid hydrogen, when he saw the potential application of technology to electricity storage.
The system reminds us of similar experiments, such as a prototype from India that stores energy by lifting heavy bricks and discharging it by lowering them. “It’s very interesting,” he told the BBC. “We need many different forms of energy storage and I’m sure liquid air will be one of them.”
Airbus unveils three models of hydrogen-powered aircraft
The European aerospace company Airbus has come up with three models of aircraft that are based on hydrogen energy, rather than kerosene pollution.
The concepts, collectively known as “ZEROe”, are part of the company’s efforts to put the first commercial zero-carbon aircraft into operation by 2035, reports Bloomberg.
Thus, a design is designed to carry up to two hundred passengers with a range of two thousand nautical miles. The project includes a hydrogen turbofan, which is rotated by a modified gas turbine engine. Liquid hydrogen would be stored and distributed in tanks at the rear of the aircraft.
The second design, which can carry up to a hundred passengers, uses a turboprop engine, which also runs on hydrogen. It is intended for short-distance travel, covering about a thousand nautical miles.
Finally, a third model, the largest of the three, is designed to accommodate two hundred passengers. The concept combines the wings with the main body, creating a massive open space. “The extremely wide fuselage opens up multiple options for hydrogen storage and distribution and for cabin layout,” an Airbus statement said.
