CEO of German energy company RWE has called for the use of hydrogen in areas where electrification is not an option, telling CNBC that “eventually, all hydrogen needs to be green.”

In an interview earlier this week it was given to Markus Krebber that Volkswagen CEO Herbert Diess has argued that hydrogen is not the answer for the German auto giant.

“I actually agree with Herbert Diess because… he said that hydrogen is not the solution for passenger transport and I think here, electrification – direct electrification – is the solution,” Krebber replied. word.

“But we need hydrogen for the non-electrified parts of the economy,” he said. “So let’s think about aviation, ocean freight, heavy trucks, but also… steel and chemicals.”

Diess has previously expressed strong views on the use of hydrogen in cars. “It’s Time for Politicians to Accept Science” he tweeted back in February.

“Blue hydrogen is essential for steel, chemicals, aviation… and shouldn’t end up in cars,” he said.

“Too expensive, inefficient, slow and difficult to deploy and ship. After all: there are no #hydrogen cars in sight.”

Hydrogen, which has a wide range of applications and can be deployed in many industries, can be produced in a number of ways.

One method involves using electrolysis, with an electric current splitting water into oxygen and hydrogen.

If the electricity used in this process comes from a renewable source such as wind or the sun then some call it green hydrogen or renewable hydrogen.

Today, many colors – including brown, blue, gray and pink, are used to distinguish between different methods of hydrogen production. For his part, Krebber explains that it’s important to be pragmatic about color coding.

“Ultimately, all hydrogen needs to be green, because green hydrogen is the only fuel that is… completely decarbonised,” he said. Meanwhile, industries need to make decisions to invest in new facilities and make them “H2-ready”.

“Of course, there’s not enough green hydrogen available in the short term, so you need to allow them to run on natural gas first, and then, possibly, on all the other colors. [of] hydrogen…especially blue,” he said.

Green hydrogen refers to hydrogen produced with natural gas – a fossil fuel – with CO2 emissions generated in the process being captured and stored.

While there is excitement in some quarters about the potential of green hydrogen, much of hydrogen generation is currently fossil fuel-based.

In recent times, several business leaders have spoken about the problems they feel are facing in the emerging field of green hydrogen. In October, such as the CEO of Siemens Energy told CNBC that yes “There is no commercial case” for it at this time.

Looking at the bigger picture and the evolution of the hydrogen economy, RWE’s Krebber sought to outline how existing infrastructure could be utilized in the coming years.

“Today we already have a dense pipeline network across Europe,” he said. “And really what we’re intending to do as an industry, we want to repurpose existing fossil infrastructure into new green infrastructure.”

Krebber’s views echo those of Marco Alverà, CEO of the Italian company Snam, this early year. In July, Alverà outlined a vision for the future of hydrogen, saying its “beauty” was that it could Easy to store and transport.

Speaking to CNBC, he talked about how existing systems would be used to facilitate the delivery of hydrogen produced using renewable sources as well as biofuels.

“Right now, if you turn on your heater in Italy, gas flows from Russia, from Siberia, in the pipelines,” he said.

“Tomorrow we will have hydrogen produced in North Africa, in the North Sea, with solar and wind energy sources,” says Alverà. “And that hydrogen can move through the existing pipeline.” CEO of energy giant RWE
