So what

Specifically, this morning Swiss renewable energy producer Axpo Holding announced it is expanding production of green hydrogen in the town of Brugg, Switzerland.  

As the company explained in a press release, it already has green hydrogen projects underway in Italy. Now, it will be building a new facility near its "run-of-river power plant" in Brugg. The new plant, projected to have a 15-megawatt installed capacity able to produce around 2,000 metric tons of green hydrogen annually, will receive its power from Axpo's nearby Wildegg-Brugg hydropower plant. The plant's capacity will support the fuel needs of "about 300 trucks and buses a year," according to Axpo, and should come on line by the end of 2023.

Now what

You might not have heard of Axpo before -- but that doesn't mean it's a small company. It's already "Switzerland's largest producer and Europe's leading marketer of renewable energies in Europe," according to the press release, saying it "intends to take a leading role in this area."

And the company is off to a good start. According to data from S&P Global Market Intelligence, privately held Axpo Holding boasts $5.1 billion in annual revenue -- and annual profits approaching $1.5 billion.

These are impressive numbers. Far more impressive than, for example, Plug Power's $31.3 million in trailing-12-month revenue, and its $751 million net loss. As the race for leadership of the hydrogen economy heats up, Plug Power's competitors are multiplying -- and Plug's success is no sure thing.
