For decades, Dynapower has built rectifiers and switchmode power supplies of varying sizes to power electrolyzers that generate clean burning hydrogen to power numerous industrial processes. With the help of our DC/DC converters and inverters, Dynapower is now helping to power the production of hydrogen fuel with clean renewable energy from solar and wind furthering the impact of hydrogen on the decarbonization of our fuel supply.

As part of an clean energy transition worldwide, hydrogen alongside batteries and renewables is poised to take on increasing role in the decarbonization of our planet. While still relatively unknown in some circles, there is a new wave coursing through the renewable energy sector and that wave is being dubbed “green” hydrogen. As the world looks to drop harmful fossil fuels in favor of energy that is produced without harmful emissions, green hydrogen has rocketed to the forefront of that conversation.

Essentially, all you need to produce green hydrogen is large amounts of water, a large electrolyzer and a sufficient amount of electricity. If you utilize green energy sources such as wind, solar or hydro to power the electrolysis, then you’ve created green hydrogen.

This is good news for sectors that have traditionally been very difficult to electrify—including aviation, heavy industrial applications and marine shipping. According to GreenTech Media, Europe is already planning to utilize a country-wide green hydrogen strategy as part of its trillion-dollar Green Deal package.

“We cannot electrify everything,” said WindEurope CEO Giles Dickson. “Some industrial processes and heavy transport will have to run on gas. And renewable hydrogen is the best gas. It is completely clean. It will be affordable with renewables being so cheap now.”

Currently, the majority of hydrogen produced today is done in a process that carries significant pollution as it is produced with fossil fuels. When it comes to green hydrogen—which previously was considered too expensive to produce on a large scale—costs are expected to fall significantly thanks to cheaper renewable energy sources combined with rapidly declining equipment costs and the introduction of Dynapower’s DPS-500 DC/DC converter which makes coupling renewables directly to an electrolyzer possible.

The applications for green hydrogen are plentiful and could potentially help the world achieve a fully renewable electricity system. While Europe is already planning for wide-scale adoption of green hydrogen, Germany has chosen hydrogen as the top choice for its green stimulus funds. France has announced a 30GW hydrogen fuel production goal over the next decade. Korea and Japan are also set to notably increase their hydrogen subsidies while the U.S. is expected to rapidly grow its hydrogen productions with a slew of new policies being pushed.

Green hydrogen is perhaps the leading proposed solution to full decarbonization and the elimination of greenhouse gases. Traditionally, heavy industry and aviation have been categories that troubled policy makers, but green hydrogen seems to be the ideal solution for powering these industries.

More specifically, green hydrogen can be used to replace polluting diesel trucks by switching over to hydrogen fuel cell trucks. The cost of these fuel cells is expected to drop up to 75 percent by 2030, according to Bloomberg. Adopting hydrogen fuel cells could replace fossil fuels used in the aviation and marine shipping industries. Finally, green hydrogen could power industries like steel and chemical manufacturing as well.

Green hydrogen’s potential for creating a renewable grid is catching on quick. It’s also a way to balance the ups and downs of renewable energy production so that excess energy can be used effectively and efficiently. By pairing electrolyzers with renewable assets and storing the energy in large tanks or powering fuel cells, solar and wind asset owner will see new revenue opportunities.

According to WoodsMackenzie, green hydrogen currently accounts for less than one percent of all hydrogen production but is expected to be 12 times the size of today’s total market by 2025.

Dynapower is proud to be a part of this clean energy revolution.
