Hydrogen to store green electricity

Hydrogen plant 'Hybalance' Denmark

Hydrogen plant ‘Hybalance’ Denmark

In windy regions like the north of Europe, the challenge is to store all the green windmill electricity.

Of course the large amounts of electricity can be stored in batteries but Denmark, the Netherlands and Germany are investing in hydrogen to store the energy.

CSP Heathens North Europe

CSP Heathens North Europe

Brønderslev, a Danish municipality with a population of 12,500, is setting up a multi-purpose renewable heat plant for their district heating network

It’s not gas, nor oil, its CSP (Concentrated Solar Power) that will heathen a small village in Denmark, North Europe, during the cold winters.

Denmark is a frontier for renewable energies and smart energy systems. Let’s have a look at the advantages of CSP for the region because normally we expect CSP in Southern parts of the world. Don’t we?

Floating Power Plant

Floating power plant

The platform rotation is secured via the high wave absorption of 60-80% of the inherent energy in the waves.

This Floating Power Plant is targeting 
20GW, corresponding to €50bn potential revenue. The Power Plant is offshore proof and grid connected.

Denmark is convinced that this wind- and water energy plant is a significant step forward in world challenge to change into renewables. Read More

Wind Power Hub North Sea

Wind Power Hub North Sea

TenneT’s thinking is based on an island with a modular structure, with each module covering approximately 6 km². This is big enough to provide space for connecting roughly 30 GW of offshore wind capacity. The island will be expandable by adding one or two modules of 6 km² each

An Energy Hub in the middle of the North Sea? Tennet launched a vision building an island as a hub, for wind power in the middle of the North Sea which will provide all neighboring countries green energy.

By connecting wind farms with a total capacity of over 30 gigawatts, the efficiency and costs will benefit the participating countries.

This plan was presented by TenneT last week. TenneT is the national high-voltage grid operator in the Netherlands and in a part of Germany. Read More

Windturbine with 4 rotors

Vestas Windturbine with 4 rotors

In cooperation with the Technical University of Denmark, Vestas is installing a concept demonstrator to test the technical feasibility to operate and control a multi-rotor turbine.

A windturbine should generate more electricity. But how?

The Danish Vestas Wind Systems may have an answer.

The company is currently testing a windturbine with four rotors. Read More

EU Grid for renewables

EU Grid

Interconnections are necessary to ensure the continued security of supply in the European electricity market and to secure the the supply of renewable electricity between European Countries.

The EU (European) Grid for renewables is connecting more and more countries. At this moment an interconnector is build from the Netherlands to Germany.

The Dutch Grid company TenneT uses a new proprietary ‘Wintrack Mast’. This ‘Wintrack Mast’ has a much smaller electromagnetic field than conventional masts and – because of its sleek design – it fits better in the living environment. Read More

Danish World Record: 42% electricity is wind power

Denmark has established a world record: in 2015 42.1% of all electricity was generated by wind power.

The Danish government is a strong advocate of wind energy.

In 2020, the Danish goal is to produces 50% of the electricity by wind turbines. This goal will be achieved before. Read More

Alcohol in the urine? That is no objection. Urine is filled with nitrogen and phosphate, useful substances, which do just fine as fertilizer in agriculture.

During the Nijmegen ‘99th Four Days Marches event, all visitors will be invited to pee not in nature or against churches on special toilets. For 7 days their urine will be collected.

The goal: reuse the huge pool as fertilizer for the growth and development of vegetables and plants. Read More
