Green hydrogen

Why hydrogen is the fuel of the future 

As 47% of the world’s industries aren’t compatible with electrification, we will need viable alternatives to fully move away from fossil fuels. Clean hydrogen will be one of them. In fact, the growing demand for green and blue hydrogen means that it could represent over 20% of the world’s energy demand by 2050. 

Hydrogen is a suitable energy carrier and feedstock for many applications, especially in the hard-to-abate sectors. So, providing that it comes from renewable and low-carbon sources, this could be a vital component on the road to net-zero. We can already see the key role that hydrogen, and its derivatives, will play in several industries, like chemical and steel production. It can also be used as fuel in marine and on/off road transportation sectors, as well as providing flexible power generation. 


How clean hydrogen is produced

Green, or clean, hydrogen is produced using an electrolyser, where renewable electricity splits water molecules into hydrogen and oxygen.

Whether you are using PEM, Alkaline or Solid Oxide electrolyser technology, Alfa Laval has an energy efficient and scalable solution for you. Our heat transfer technology can support you with everything from cooling electrolytes and gases, to recovering excess heat, and balancing of the plant.

On top of that, our freshwater generation technologies make it possible for our customers to reuse the excess heat from their electrolyser, while also converting sea or river water into the pure water needed for these applications.

Green hydrogen gives hope for the future

Green hydrogen has long held promise for achieving Europe’s climate targets. Now in Germany, a new pilot project is showing the potential to make this a reality. Using Alfa Laval heat exchangers, Thyssenkrupp Uhde Chlorine Engineers GmbH is testing hydrogen instead of injection coal to reduce CO2 emissions in ongoing blast furnace operations at its Duisburg site. The only thing left over from this new process is water vapor.

This project, which is funded by the German government, uses the metallurgical gases produced during steelmaking to produce chemicals, thus reducing CO2 emissions in both steelmaking and chemical production. Check out the full story to learn more about the critical role Alfa Laval technology has played in this pilot.

Alfa Laval Niagara Wet Surface Air Coolers (WSAC)

Wet Surface Air Coolers (WSAC®) are a perfect fit for all cooling needs in hydrogen compression and transport. They are custom-built, closed-loop evaporative cooling and condensing systems. By direct cooling of the process fluid, a WSAC system can reach lower temperatures and is more compact than any alternative air cooler technology. And since no high-quality fresh water is required, with low-quality waste water instead used as cooling medium, they also offer a very sustainable solution.
