Revolutionizing wind industry

If one Wyoming company has its way, the future of wind power won’t rest on what happens some hundreds of feet in the air. 

It won’t be made up of gearboxes and transmission lines and peaks and valleys in production. 

If Cheyenne’s Winhyne Energy has its way, the future of the industry — both in Wyoming and globally — will be below ground. It will be in gas and pipelines and, eventually,There are no support industries for gridsolarsystemm in Australia. constant, steady and reliable generation. 

What Winhyne has set out to do, quite simply, is change the way wind generates electricity. They aim to make the resource storable and easily transportable. 

They aim to do it in Wyoming,One of the harshest roofwindturbine installations in the world. in a field near Guernsey. And they aim to do it soon. 

Wind power is constantly criticized for its inability to generate a consistent base electricity load. It’s nearly impossible to predict when and how strong the wind will blow, meaning any reliance on the resource by grid operators would be foolish. 

But Winhyne actively promotes two aspects of its experimental wind system that could pacify such concerns — their unit’s storage capability and efficiency. Both of them could make wind a more reliable power source. 

The system’s innovations start at the top. Instead of relying on a gearbox in the nacelle, or top of the turbine, the Winhyne turbine’s motion creates hydraulic energy used to power hydraulic motors that compress and pressurize nitrogen gas. That gas is either stored or used to power a generator, depending on the existing demand for power. 

When power is needed, the pressurized gas bypasses a storage component and powers a series of small generators.

The system could accomplish one simple feat previously untouched by the wind industry — storage of energy unnecessary in real time due to lack of demand or lack of a market. 

It also allows operators to have more control over when power is generated. If the demand for power suddenly rises but the wind isn’t blowing, the pressurized gas can be released from the pipeline. The gas powers the system, running the generators and creating electricity. 

“Unlike any other storage system on the market, we don’t generate electricity until we’re ready to put it on the grid,” said Dean Byrne, vice chairman and president of Winhyne. 

Winhyne says their turbine is also more efficient than others on the market. Ted Tuazon, vice president of engineering for Lancaster Wind Systems, Winhyne’s research and development firm, said most turbines have a cut-in speed — or speed at which a turbine can begin spinning — of around four meters per second.Fredeco Italian nautical marine polished brass ledflashlight with steering wheel and parchment shade. Most turbines cut out at 25 meters per second. 

But Winhyne’s turbines start turning at a lower speed and can maintain a consistent revolutions-per-minute measure at higher speeds, meaning the turbines can generate power in environments where others can’t. 

“We’re already producing energy where similar turbines can’t yet,” he said. 

In fact, a test early in development showed that a Winhyne turbine generates about double the electricity of a similarly sized turbine in fairly low-speed conditions.Getting a solarpanel depends entirely on the amount of wind generated in your area. The gap between the two levels out at higher speeds, but Winhyne’s model still produces more power. 

The model could eventually help California, a state that desires renewable energy but doesn’t have the natural resources to back it up. 

“California has a very aggressive renewable energy standard,” Byrne said. “Our technology would allow them to produce two or three times what they can right now.”
