New insulation material: more efficient electricity distribution

Illustration: Chalmers University of Technology

High-voltage direct current cables (so-called HVDC cables) which can efficiently transport electricity over long distances play a vital role in our electricity supply. Optimising their performance is therefore an important challenge. Recently Chalmers University of Technology, Sweden, presented a new insulation material up to three times less conductive, offering significant improvements to the properties and performance of such cables.

To a future world, powered by renewable energy, efficient long-distance transport of electricity is essential. Renewable energy sources such as wind and solar farms, as well as hydroelectric dams - is often located far from cities, where most of the demand exists. HVDC cables with an insulation layer can be buried underground or laid on the seabed. During transport, as little energy as possible should be lost. Insulation plays an essential role in this. Researchers of Chalmers University of Technology now present a novel insulation material based on polyethylene, which is already used for insulation in existing HVDC cables. Now, by adding very small amounts - 5 parts per million - of the conjugated polymer known as poly(3-hexylthiophene), the researchers were able to lower the electrical conductivity by up to three times. The additive, also known as P3HT, is a widely studied material, and given the tiny amounts required, opens up new possibilities for manufacturers. Other possible substances that have previously been used to reduce the conductivity are nanoparticles of various metal oxides and other polyolefins, but these require significantly higher quantities. Conjugated polymers, such as P3HT, have been used in the past to design flexible and printed electronics. However, this is the first time they have been used and tested as an additive to modify the properties of a commodity plastic. The researchers therefore believe that their discovery could lead to numerous new applications and directions for research.

Cooling with salt (and sunlight)

Scientists of the King Abdullah University of Science and Technology (KAUST) of Saudi Arabia, developed a simple cooling system driven by the capture of passive solar energy and salt. According to KAUST the installation could provide low-cost food refrigeration and living space cooling for impoverished communities with no access to the electricity grid. The system, which has no electrical components, exploits the powerful cooling effect that occurs when certain salts are dissolved in water. After each cooling cycle, the system uses solar energy to evaporate the water and regenerate the salt, ready for reuse. That can be useful, because in many parts of the world, there is a greater need for cooling because of climate change, but not every community can access electricity for air conditioning and refrigeration.

The team designed a two-step cooling and regeneration system, with the cooling step based upon the fact that dissolving certain common salts in water absorbs energy, which rapidly cools the water. After comparing a range of salts, ammonium nitrate (NH4NO3) proved to

be the standout performer, with a cooling power more than four times greater than its closest competitor, ammonium chloride (NH4Cl). The ammonium nitrate salt’s exceptional cooling power can be attributed to its high solubility. According to KAUST the system has good potential for food storage applications. When the salt was gradually dissolved in water in a metal cup placed inside a polystyrene foam box, the temperature of the cup fell from room temperature to around 3.6 degrees Celsius and remained below 15 degrees Celsius for more than 15 hours.

Once the salt solution reached room temperature, the team used solar energy to evaporate the water using a bespoke, cup-shaped 3D solar regenerator. The cup was made from a material designed to absorb as much of the solar spectrum as possible. As the water evaporated, the NH4NO3 crystals grew over the cup’s outer wall. Once collected, the salt effectively represents a stored form of solar energy, ready to be reused for cooling again when required.

Enterprise Europe Network (EEN) supports companies with international ambitions

The Enterprise Europe Network (EEN) is an initiative of the European Commission that supports entrepreneurs in seeking partners to innovate and do business abroad. The Network is active in more than 60 countries worldwide. It brings together 3,000 experts from more than 600 member organisations – all renowned for their excellence in business support.

Database

Every company can participate by adjusting its profile to the database. This company will be brought to the attention in the country in which it wants to become active. At the same time it is possible to search for partners. EEN advisers actively assist in compiling the profile, which is drawn up in a certain format. The EEN websites also contain foreign companies that are looking for Dutch companies and organizations for commercial or technological cooperation. The EEN advisers support the search for a cooperation partner by actively deploying contacts within the network. In addition, Company Missions and Match Making Events are regularly organized. All these services are free of charge.

There are five types of profiles:

• Business Offer: the company offers a product

• Business Request: the company is looking for a product

• Technology Offer: the company offers a technology

• Technology Request: the company is looking for a technology

• Research & Development Request: the organization seeks cooperation for research

When a company has both a Business Offer and a Business Request (or another combination), two (or even more if applicable) profiles are created. The profile includes the most essential information about the nature of the supply or demand, the ‘type of partner’ that is intended and the expected cooperation structure.

Get in touch with your local network contact point by selecting the country and city closest to where your business is based. They can help you with advice, support and opportunities for international partnerships.

Innovative Materials, the international version of the Dutch magazine Innovatieve Materialen, is now available in English. Innovative Materials is an interactive, digital magazine about new and/or innovatively applied materials. Innovative Materials provides information on material innovations, or innovative use of materials. The idea is that the ever increasing demands lead to a constant search for better and safer products as well as material and energy savings. Enabling these innovations is crucial, not only to be competitive but also to meet the challenges of enhancing and protecting the environment, like durability, C2C and carbon footprint. By opting for smart, sustainable and innovative materials constructors, engineers and designers obtain more opportunities to distinguish themselves. As a platform Innovative Materials wants to help to achieve this by connecting supply and demand.

Innovative Materials is distributed among its own subscribers/network, but also through the networks of the partners. In 2021 this includes organisations like M2i, MaterialDesign, 4TU (a cooperation between the four Technical Universities in the Netherlands), the Bond voor Materialenkennis (material sciences), SIM Flanders, FLAM3D, RVO and Material District.
