Battolyser: the super battery

Battolyser: the super battery

If this large-scale storage of renewable energy in liquid ammonia succeeds, communities can cover long low wind and solar energy periods

The Battolyser, which will be used as a super battery in a gas power plant, is becoming a reality. 

For the first time, TU Delft researchers led by Prof. Fokko Mulder have produced an integrated battery electrolysis system – known as a ‘battolyser’ – that can not only store or supply electricity efficiently as a battery but can also split water into hydrogen and oxygen using electrolysis.

Merits Heat Battery Tested

Merits heat battery

The thermal energy can be stored with a high density while limiting the energy losses to the ambient

Since May 2016, the Merits prototype of a compact rechargeable heat battery is tested. The test will take the whole summer. 

The battery is developed including high energy density thermochemical materials that can supply required heating, cooling and domestic hot water for a dwelling with up to 100% renewable energy sources (e.g. the sun) throughout the year. 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

Research Report Smart Cities

Delft - Research Report Smart Cities 2015 - 2050

Smart urban design requires an integrated look at the city as a complex of material flows and living environment, which exposes the connections between sources, functions, infrastructure and users.

This Research Report ‘Smart Cities’ has been published by the University Delft. The researchers consider Smart Cities as a way of working on a future-proof city, cleverly making use of people, resources and systems.

In this Delft Smart City research project, students examined the possible impact of recent developments under the heading ‘Smart City’ for Delft.

From CO2 to Valuable Carbon Nanofibers

From CO2 to strong and valuable nanofibers, this is a high potential technology

The strong nanofibers can be used for strong carbon composites which are used in planes, bikes, wind turbine blades and space equipments.

In 2015, a research team from the George Washington University presented a technology that converts CO2 (directly from the air) into highly valued carbon nanofibers for industrial and consumer products. 

The strong nanofibers can be used for strong carbon composites which are used in planes, bikes, wind turbine blades and space equipments. Read More

different technologies can be used for micro-CHP, including stirling engines, rankine engines, internal combustion engines, and fuel cells.

Fuel cell based micro CHP units in homes and commercial buildings can help the electricity grid assimilate more renewables according to the Technical University of Denmark.

Scientists published a report explaining the need to create a market for electricity services to draw new technologies such as micro CHP into wider use and accelerate the cost reduction needed for general consumer uptake. Read More

Invisible light converts to +30% electricity

infrared, solar, electricity, renewables, US, smart grid, university

Applications of the research include more energy-efficient lighting and photodetectors with 200 percent efficiency that can be used for night vision.

Chemists at the University of California (UCR) have developed a material that uses infrared light to convert it to visible light.

This allows solar panels to generate 30 percent more electricity. Read More

Needed: Amazon Green 4-helix Cooperation in Brazil

Brazil, water, pollution, Indians, NGO, clean water, fresh water, sustainable infra

Clean water in the Amazon is essential for Indians in the Amazon and all Brazilian civilians

The planning and implementation of a new approach to water resource management in the Amazon region will need to involve the four dimensions of a green helix initiative:

  1. government
  2. universities and research centers
  3. private sector
  4. non-governmental organizations (NGOs)
