Gas Turbines Have Become by Far the Best Choice for Add-on Generating Power

They offer instant-on power that's compact, mobile, quiet, economical, durable, and matchlessly efficient

Eighty years ago,the world’s first industrial gas turbine began to generate electricity in a municipal power station in Neuchâtel, Switzerland. The machine, installed by Brown Boveri, vented the exhaust without making use of its heat, and the turbine’s compressor consumed nearly three-quarters of the generated power. That resulted in an efficiency of just 17 percent, or about 4 MW.

The disruption of World War II and the economic difficulties that followed made the Neuchâtel turbine a pioneering exception until 1949, when Westinghouse and General Electric introduced their first low-capacity designs. There was no rush to install them, as the generation market was dominated by large coal-fired plants. By 1960 the most powerful gas turbine reached 20 MW, still an order of magnitude smaller than the output of most steam turbo generators.

This Dutch City Is Road-Testing Vehicle-to-Grid Tech

Utrecht leads the world in using EVs for grid storage

The Dutch city of Utrecht is embracing vehicle-to-grid technology, an example of which is shown here—an EV connected to a bidirectional charger. The historic Rijn en Zon windmill provides a fitting background for this scene.

We Drive Solar

Hundreds of charging stations for electric vehicles dot Utrecht’s urban landscape in the Netherlands like little electric mushrooms. Unlike those you may have grown accustomed to seeing, many of these stations don’t just charge electric cars—they can also send power from vehicle batteries to the local utility grid for use by homes and businesses.

Debates over the feasibility and value of such vehicle-to-grid technology go back decades. Those arguments are not yet settled. But big automakers like Volkswagen, Nissan, and Hyundai have moved to produce the kinds of cars that can use such bidirectional chargers—alongside similar vehicle-to-home technology, whereby your car can power your house, say, during a blackout, as promoted by Ford with its new F-150 Lightning. Given the rapid uptake of electric vehicles, many people are thinking hard about how to make the best use of all that rolling battery power.
