Water for Energy Transition

Water is a crucial resource for many products and processes that will guide our journey toward the energy transition, and companies that work in water treatment will be responsible for empowering the industry to use this resource sustainably.


Biofuels are a green alternative to fossil fuels, where organic sources, such as biomass or vegetable oils, are used as feedstock instead of crude oil. This allows the production of sustainable and low carbon substitutes for conventional fuel through a specific sequence of chemical conversion steps.

Water is a crucial resource in the production of biofuel. The bio-refinery processes produce a significant amount of effluent water contaminated with organics and other highly polluting contaminants.

We are the right partner to design, engineer, and supply a customized solution for such complex wastewater treatment and wastewater reuse plants.

EV Batteries

The current and expected pace of growth in the number of Electrical Vehicles (EV) around the globe is increasing rapidly, reflected in the billions of dollars invested annually to increase the production capacity of EV batteries.

Like any industrial process, water plays a significant role in the production of EV batteries, but not only as a utility. Ultrapure water produced by demineralization is used in the production process of batteries and their intermediates.

Our team lends its process engineering and system integration expertise to co-create tailor-made solutions for low or zero carbon-emitting energy projects with the leading players in the field.


Hydrogen is now hailed as a viable and rapidly developing pillar for the Energy Transition: it is an energy vector with the potential to help decarbonize several energy-intensive sectors, such as steel and cement, aviation, and shipping.

Hydrogen is not found in its molecular form in nature; it needs energy to be produced. This means it can have different labels based on the energy source employed and its carbon intensity.

Grey H2

The vast majority of current H2 production is through unabated, partial oxidation of fossil fuels. This leads to significant production and emission of CO2 as a by-product in the atmosphere.

Blue H2

Also known as low carbon H2, blue H2 is produced by coupling the traditional H2 production process (by partial oxidation) with a process to decrease CO2 emissions. The CO2 is captured and either reused or permanently stored through Carbon Capture, Utilization and Storage (CCUS) processes.

Green H2

Hydrogen can be produced through electrolysis by splitting water into gaseous hydrogen and oxygen through an electrochemical reaction. If the source of electrical power is renewable, it produces zero-carbon hydrogen.

  • Green H2 has the potential to be used to store power produced by intermittent sources like solar and wind power
  • It acts as a green feedstock for chemicals (fertilizers) and sustainable fuels (green ammonia)

Ultrapure, demineralized water is the feedstock for most industrial hydrogen production processes. In the case of green H2, the lack of access to purified water could spell the death of a potential green hydrogen project.

With vast experience in industrial water treatment, solutions developed by our team at Cannon Artes can maximize the efficiency of water treatment plants and minimize or re-use the effluents, contributing to the successful development of these projects.

Carbon Capture, Utilization and Storage (CCUS)

Removing CO2 from gaseous streams is a well-established process based on mature technologies, widely used in the upstream Oil & Gas sector and natural gas treatment.

CO2 emissions can be separated with the same or new and innovative processes and technologies to be utilized or permanently stored. This process, known as Carbon Capture, Utilization and Storage (CCUS), can decarbonize hard-to-abate and carbon-intensive fields such as power generation, cement, and steel.

CCUS is performed with a wide range of processes, each characterized by specific complexities. In addition to the standard utility water requirements, virtually any CCUS technology needs a carefully tailored and customized wastewater treatment and reuse process.
