Casa dos Ventos has been advancing its operations in the green hydrogen segment, with the approval from the CZPE (National Council of Export Processing Zones) for the installation of a plant dedicated to green hydrogen and ammonia in the Pecém Export Processing Zone, in Ceará.
The initiative, still in the development phase, involves engineering activities, supplier selection, negotiation with potential partners, and evaluation of off-takers, making it one of the company's most structured projects in addition to its wind and solar ventures.
CEO Lucas Araripe states that the company is working simultaneously on several fronts, focusing on technical and economic studies.
According to him, the plan is to make available 1,2 GWm of renewable energy from wind and solar farms, distributed between the Northeast and Southeast regions, to enable the production of up to 900 tons of green ammonia annually.
Initial estimates indicate investments of R$ 12 billion in the main plant and another R$ 13 billion in associated generation projects. The final investment decision is expected in 2026, and the plant is expected to become operational from 2030 onwards.
In Partnership with
The executive explains that the TotalEnergies [Company Name] is the partner linked to the project in Pecém, through the existing partnership between the companies. Their joint objective is to evaluate technological models, identify ways to reduce costs, and meet certification criteria required by the European market.
A PetroBrazil, although it signed a memorandum of understanding with Casa dos Ventos in 2023 for general studies on renewables, is not participating in this specific initiative, and the MoU expires in 2025.
Necessary incentives
In the regulatory field, Araripe emphasizes that the development of green hydrogen in the country depends on public policies focused on competitiveness.
He cites five points considered relevant: tax incentives, definition of an adequate regulatory framework, stimuli to domestic demand, long-term contractual mechanisms, and international cooperation for standardization and access to equipment.
For House of the WindsThese measures will be important to enable industrial planning and reduce production costs.
The CEO emphasizes that the availability of renewable energy in Brazil creates favorable conditions for the development of the low-carbon hydrogen supply chain, especially considering European certification requirements.
The company's initial focus remains on ammonia exports, given the potential for external demand. However, the company is also evaluating projects for the domestic market, including industrial applications and use in fertilizers.
Possibilities associated with green methanol Navigation is also part of the ongoing studies.
Araripe notes that the current cost of green hydrogen, estimated between US$4,6 and US$9,51, is still significantly higher than that of gray hydrogen. He believes, however, that there is a trend towards price reduction due to economies of scale, the evolution of electrolysis technologies, and potential incentive mechanisms foreseen by national and international programs.
According to him, hydrogen can play a significant role in the future competitiveness of industrial sectors seeking to reduce their emissions.
With the legal framework approved in 2024 — including Rehidro and PHBC (Low-Emission Hydrogen Development Program) —, Araripe believes that the country has established important initial guidelines.
Conversely, it points out that further regulations are still needed, as well as definitions regarding technical criteria, funding sources, and certification models.
According to the executive, the consolidation of large-scale projects will depend on regulatory stability and instruments that allow for long-term predictability.
