Powerfuels Brief: Water consumption for the production of green hydrogen

As part of our ‘Powerfuels Brief’ series, the Global Alliance Powerfuels will be hosting a digital event on an aspect linked to the sustainability of renewable hydrogen that is increasingly gaining interest: water consumption.

Presenting insights from the Alliance’s forthcoming position paper on the topic, we will discuss how to ensure that the water needed for the production of green hydrogen and green hydrogen derivatives is sourced and consumed sustainably. Join the presentation and discussion with expert guest speakers on October 25, 2021!

Powerfuels Brief: Water consumption for the production of green hydrogen
Demand, supply, and policy recommendations to ensure environmental sustainability

Powerfuels – green hydrogen as well as gaseous and liquid fuels from power-to-X processes using renewable electricity - will play an indispensable role in achieving the EU’s 2030 climate target of reducing emissions by 55% and, ultimately, the goal of climate neutrality by 2050.

Water consumption is gradually gaining more attention in the discussion on sustainability of powerfuels. The amount of water required in practice to produce one kilogram of hydrogen through electrolysis amounts to approximately 11 litres..

The amount of water consumed to produce and refine the fossil-based energy carriers powerfuels can replace is even higher. Nonetheless, ramping up global production capacities of renewable hydrogen and powerfuels would lead to a significant water demand. An airplane flying from London to New York operated on 100% green hydrogen-based kerosene would require 550,000 liters of water for the production of said kerosene, or as much as the daily water consumption of 1,800 US citizens.

Considering that optimal production sites for green hydrogen often reside in water scarce areas, ensuring environmentally sustainable water extraction and consumption practices is imperative to ramp-up and sustain global production capacities.

With European legislation lacking concrete sustainability criteria for water consumption for the production of powerfuels, the Global Alliance Powerfuels will present insights from its forthcoming position paper on the topic and discuss policy recommendations to avoid water stress with policy and industry experts in a digital event as part of our ‘Powerfuels Brief’ series.
