(Kitco News) - Siemens said demand for hydrogen is expected to increase by 7% per year until 2050, wrote the company in a white paper released today.

Hydrogen is today used primarily in refining processes or to make ammonia for the fertilizer industry, notes Siemens. About 98 % of today's hydrogen is produced using fossil fuels, mainly by reforming natural gas and through coal gasification.

Siemens manufactures, installs and services wind turbines. The company said it has installed stations generating more than 110 GW in total.

"The world needs up to 6,000 GW of new installed renewable energy capacity by 2050, up from 2,800 GW today to generate the expected demand for hydrogen," writes the company.

Hydrogen costs need to be driven down, and hydrogen needs to be generated from renewables, said Siemens, noting that more work is needed on infrastructure, logistics, storage and distribution.

Siemens has a rollout plan for test plants.

"Since the 2050 target of carbon neutrality will require green hydrogen generation at scale, Siemens Gamesa as a technology company will accelerate its efforts to bring a prototype of the offshore wind-to-hydrogen solution to market in the next five years, followed by the first industrial scale wind plant shortly thereafter. If the first 2 GW of offshore wind-to-hydrogen plants are installed by 2030, followed by another 10GW by 2035, the volumes will provide the scale needed for offshore hydrogen to reach cost parity by 2035," wrote Siemens.
