Dresden (Germany)/Aqtau (Kazakhstan) – August 25, 2025 – Germany-based Svevind Energy Group completed several Value Engineering Studies of its ambitious green hydrogen project Hyrasia One in the Mangystau region of western Kazakhstan. This transformative initiative aims to establish a Power-to-X hub, leveraging the region’s abundant renewable energy resources to produce green hydrogen and green ammonia on gigawatt scale.
Hyrasia One will involve the development of wind and solar photovoltaic (PV) farms with a combined capacity of approximately 40 GW. These farms will generate clean electricity to power a water electrolysis facility with a capacity of 20 GW. The industrial complex is expected to produce around 2 million tons of green hydrogen annually, starting in 2030 and reaching its full production capacity in the mid-2030’s. The green hydrogen is planned to be further processed into more than 10 million tons of green ammonia.
The primary goal of producing such a substantial amount of green ammonia is to meet the growing demand in both European and Asian markets, as well as the domestic demand in Kazakhstan. The ammonia processing will take place within the same industrial facility as the electrolysis blocks in a centralized plant concept. Additionally, a water desalination plant will be established to provide the necessary water.
Feasibility studies have identified the Mangystau region as one of the most favourable project host regions in Central Asia, given the abundance of renewable energy resources, highly motivated people with decades-long experience with energy resources and proximity to water resources required for electroylsis. The first project development phase was successfully achieved in summer of 2022 with the completion of the concept design study, prepared by Svevind Energy Group in cooperation with ILF Consulting Engineers and Roland Berger Management Consultants.
The pre-FEED Engineering package, developed by GENESIS Oil and Gas Consultants Ltd., part of group Technip Energies, focuses on the full capacity of Hyrasia One.
As part of the Value Engineering studies, Svevind Energy Group identified several work packages for further design optimization:
Renewable Production: Considering the rapid development of wind turbines and solar PV modules, updated power profiles and time series were developed using latest technology assumptions.
Grid Optimization: The power transmission system of the Pre-FEED design was mainly based on synchronous condensers for inertia and stabilization. The grid design was updated to ensure a more efficient and cost-effective solution for Hyrasia One Phase 1.
Backup Power and H2 Storage: Island grids have high demands towards electrical stability including black-start capabilities. The revised concept uses an optimized Battery Energy Storage System (BESS) that reduces yearly start/stops and operating hours of the backup gas turbines.
Cooling concept: The cooling concept was initially developed without accounting for varying temperature conditions, which required energy- and cost-intensive chiller units. By applying a detailed time-resolved model, a chiller-free cooling system was designed significantly reducing internal energy consumption.
After successful completion of the Value Engineering studies, Svevind Energy Group is now preparing the FEED engineering. In addition, Svevind Energy Group is looking forward to completion of the remaining biodiversity studies as part of the Environmental and Social Impact Assessment later this year.
Svevind Energy Group is committed to advancing renewable energy solutions and contributing to a sustainable future. The Hyrasia One project represents a significant step towards achieving these goals, providing clean energy and supporting the global transition to a low-carbon economy.
