Iridium could slow down electrolyser run-up

Although hydrogen produced from renewable energies has been under discussion for decades as a possible alternative to fossil fuels, it has so far only played a minor role. Recently, however, there have been signs of change, so that “green” hydrogen could gain momentum in the energy sector: More and more powerful electrolysis systems are available, and the prices for these systems are falling. If, however, PEM electrolysers were to be added on a large scale, iridium could become scarce and thus more expensive and thus stand in the way of a reduction in the already considerable investment costs.

Effect of hydrogen on materials

Stress-strain curves of hollow samples filled with hydrogen or nitrogen, with an internal pressure of 70 bar, tested at a draw-off rate of 3.5 µm/min.

Atomic hydrogen partly diffuses into materials during production and operation. If this results in degradation of the material properties, the term hydrogen embrittlement is used. The Fraunhofer IWM has set itself the task of better understanding and mastering such chemical processes and their consequences. For this purpose, a new laboratory for material qualification for hydrogen applications has now been set up.

Only slowly, the Energy Observer fought its way up the Elbe to Hamburg against the tidal ebb. The Hanseatic city in which the solar hydrogen ship moored on 28 April 2019 was the 35th station on the six-year circumnavigation of the world. A total of 101 locations in 50 countries are to be visited.

Realignment of the IAA

The 68th International Motor Show has to get itself re-organised. Two years ago, the organising German Association of the Automotive Industry (VDA) already had to contend with numerous cancellations by automobile manufacturers because quite a few preferred a presence at the Consumer Electronics Show in the USA to an exhibition in Frankfurt (see H2-international issue Jan. 2018).

China switches to fuel cells

This remark (“major new customers”) stuck particularly with me, because Ballard – although already on board with many top partners and large companies in research technology – expects further major new customers, according to CEO Randy MacEwen in the telephone conference on the occasion of the figures for the fourth quarter of 2018.

The momentum for the fuel cell is constantly improving with increasing dynamics. Recent co-operations such as those between Bosch and PowerCell, but also positive statements on fuel cells from automobile manufacturers such as Audi are attracting attention. Will China be the driver again, as it was when the batteries were introduced and before that in the field of renewable energies? There, new funding guidelines are about to be introduced, which are intended to favour and strongly promote the fuel cell and the hydrogen infrastructure, while the subsidies for purely battery-operated vehicles will, depending on the radius, be abolished in full or to a large extent.

Bloom Energy – on the right track

In the first quarter, Bloom was able to generate a good US$ 200 million in sales. The bottom line was a minus of US$ 8.8 million or minus US$ 0.22 per share. Nevertheless, a noticeable improvement compared with the same quarter of the previous year, in which a minus of US$ 22.5 million was reported. This represents growth of around 18.5 percent. The cash position is very healthy, amounting to US$ 327.9 million plus US$ 42 million from Power Purchase Agreements (PPAs).

FuelCell Energy – Reversal Split as Turbo of the Downward Trend

FuelCell had to feel what it means to fall for smart investors (loan sharks?). The preference shares that could be converted into ordinary shares were probably used to push down the price via short selling and to receive more and more shares due to a conversion ratio. Did the analysts who evaluate and recommend FuelCell Energy simply overlook this? Now the capital has been merged. The number of artificially inflated shares via conversion of preference shares has now been significantly reduced. Unfortunately, all this seems to leave the management cold, otherwise they would at least make a press release.
