Hydrogen Economy II

Russia and Siemens pursue research on hydrogen-fueled electricity turbines

After  President George W. Bush unveiled early in his first term a vision of a hydrogen economy--a vision that momentarily "killed" visions of an electric car--it did fot take long for the truth to sink in that it would decades at the least before motor vehicles would generally run on fuel cells fueled by hydrogen. So it came as rather a surprise to see, reading an account by a German Russia expert of a September 2006 meeting with Vladimir Putin, the following: "The age of oil will one day draw to a close. How is Russia preparing for the time after cheap oil, or indeed, after oil? Putin offers an optimistic perspective: 'We are working on hydrogen energy. In the medium term we will invest massively.' " So reports Michael Stuermer, in Putin and the Rise of Russia.

What did Putin have in mind? Was he still clinging to something like Bush's vision, well after most Americans had tossed it onto the dustbin of history?

Now comes a report from Siemens that it is working with the Russian National Research Nuclear University to develop turbines that would run on hydrogen. Siemens does not underestimate the challenges: "The idea of combusting hydrogen with oxygen to obtain water and extract a large amount of energy with zero environmental pollution is still a long way off at the moment. The production of pure oxygen is too costly and the combustion temperatures of 3,200 degrees Celsius are too high for the turbine blading used in the power plants. Natural gas, which burns at approximately 1,950 degrees Celsius, already requires air cooling of the blading. Siemens CT in Munich is therefore also conducting research intoheat-resistant ceramics for use in turbines."

Evidently that vision will be a long time comng too--if ever indeed it's realized--but it too is an interesting one.

This photograph shows a car with the words “We Drive Solar” on the door, connected to a charging station. A windmill can be seen in the background.

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.
