Our vision

We, at Alpha e-Stream, rethink the current approach.

We believe that floating wind turbines can be used not only in deep waters (more than 60m deep) but in offshore in general.

Innovative floating technologies allow to reduce floating wind costs substantially and offer an alternative to fixed foundations.

Floating wind turbines have a number of advantages. For instance, they ease turbine set-up, even for mid-depth conditions (30–50 m), floating foundations generally offer substantial environmental benefits compared with fixed-bottom designs due to less invasive activity on the seabed during installation, reducing installation time just to mention a few.

Our mission

The United States and The European Union have set out a goal  to be climate-neutral by 2050, China has pledged to achieve the same goal by 2060 – an economy with net-zero greenhouse gas emissions.

According to EU Hydrogen Strategy 10mln tonnes of renewable hydrogen must be produced by 2030, with an overall cost estimated at €430bn.

It is now estimated that green hydrogen could supply up to 25% of the World’s energy needs by 2050. Using offshore wind to produce hydrogen has significant advantages over using electricity from the grid, by avoiding the need ​for costly transmission infrastructure and ensuring the underlying source of power to produce hydrogen is clean.

The IEA estimates that offshore wind could save up to 80 % on the costs of electricity input to produce hydrogen. ​Offshore wind has a ​high and steady capacity and can make full use of the electrolysers used to produce hydrogen, especially when compared to other variable renewables such as onshore wind and solar power.

We at Alpha e-Stream see that to achieve this goal a new cost-efficient and sustainable technology has to be developed so that renewable fuels could be competitive with fossil fuels.

Today the high self-cost of renewables is the biggest reason why the green revolution is not possible.

Our purpose

Our purpose

The aim is to use our in-house team of engineers and reliable solutions from recognized suppliers to develop the most sustainable and cost-efficient solution in the market.

We with our expertise in large-scale projects together with our partners from engineering companies and universities substantially reduce the cost of green hydrogen to the point where it is competitive with fossil-based fuels.

The cost of offshore renewable wind energy can be achieved by reducing the currently high substructure & foundation cost, which accounts for 27% of the total capital expenditures for the floating offshore wind project, for comparison the substructure & foundation cost for fixed bottom offshore wind projects accounted for 15,2% of the total Capex.

Floating wind outstanding facts

The European Commission estimates that between ​240 and 450 GW of installed offshore wind power capacity is needed by ​2050 ​to keep temperature increased below 1.5°C. By 2050 30% of electricity will be generated by offshore wind.

Floating technologies would allow wind turbines in a vastly increased number of locations where the wind blows more strongly and consistently than in locations closer to shore.

Floating technologies could ​greatly scale up the capacity of offshore wind, especially if accompanied by continued advances in turbine size allowing for greater energy capture. Floating foundations could therefore have a transformative impact on the European market, where ​80 % of offshore potential lies in waters deeper than 60 meters.

Offshore wind has the potential to generate more than ​420 000 TWh per year worldwide; more than ​18 times global electricity demand today

An advantage that offshore technologies have in common is that they do not take up costly land space and do not cause resistance from nearby communities afraid of nuisance from nearby renewable energy projects

Offshore wind has capacity factors close to those of ​efficient gas-fired power plants​, ​exceeds​ those of ​onshore wind​ and is about ​double those of solar PV.

Hydrogen production outstanding facts

It is estimated that green hydrogen could supply up to ​25% of the world’s energy needs by 2050. Green hydrogen’s demand could reach about 530 million tons by 2050.

It is estimated that the green hydrogen export market could be worth US$ 300 billion yearly by 2050, creating 400 000 jobs globally.

Green hydrogen is considered to be the fuel of the future. The ability to use a fuel with a zero CO2 footprint represents a revolution in the energy and transportation sector.

The cost of green hydrogen will equal fossil fuel-based hydrogen by 2040, as the production of renewables-based hydrogen will fall by 64%.

Today nearly 73 million mt/year of pure hydrogen are consumed, about half in the oil refining industry and another 40% in the production of ammonia fertilizers. It’s production from fossil fuels is extremely carbon intensive, with 1 kg of H2 causing 11 tons of CO2 emissions.

The hydrogen can also be converted into hydrogen‑based fuels, including synthetic methane, methanol, ammonia and synthetic liquid fuels, which have a range of potential transportation uses.

Projects

Alpha e-Stream aims to become the most efficient and agile developer in the market.

By choosing our development each client receives the full turn-key project including in house front-end engineering, servicing, design and project management.

As the market develops the product develops as well – this approach will exclude expensive conversions and erection fees due to the modular nature of the technology.

In series lean production and availability of shipyard facilities with the background in offshore construction help reduce the production and construction time even further.

Each potential customer will get a personal solution according to available possibilities and conditions.

Our expertise in large-scale projects plus our highly experienced field partners will provide the most optimal and innovative solutions

Alpha S

Modular units

Alpha e-Stream is a project which combines the two most potential directions in energy at the moment – floating wind farm technology with floating hydrogen production and storage platform to produce the most sustainable offshore energy on competitive prices.

The technology consists of wind turbines on floating substructures which lets the user make the most of offshore wind potential in waters deeper than 60 m, where 80% of wind potential lies.

The wind farm can be connected to an existing electricity grid, where it will be distributed according to the demand of the client.

The second part of the project, floating hydrogen production and storage platform, is used to maximize the productivity of the wind farm

Large-scale production

Alpha e-Stream develops a modular ecosystem for hydrogen production and storage on offshore platforms. The modules perform different stages of hydrogen production.

By choosing the number and types of different modules, the customer can achieve the hydrogen production capacity and / or storage capacity that meets their specific needs.

In the future, modules can be added and replaced, which allows you to easily adapt to changes in production volume, divide the investment over a longer period of time and replace obsolete modules when new technologies enter the market.

Surplus electricity from the wind farm is used for water electrolysis to generate green hydrogen that can be stored and used as feedstock for PEM fuel cells to produce electricity when it’s needed.

Alternatively, the stored hydrogen can be burned in internal combustion engines to generate mechanical or electrical energy.
