Projects within "Energy Efficiency with Nanotechnology"

Four projects received a total of NOK 48 million in funding from the sub-program. Total budget of the projects is NOK 110 million. The projects will run for three years from 2010 until 2013.

Research towards Nordic Industrialization of the Salt-and-Paper Battery

The objective of the project is to carry out the research

and development necessary to form the foundation for

future commercialisation of a new type of paper-based,

environment-friendly supercapacitors and battery.

 

The Salt and Paper Battery is a supercapacitor with electrodes consisting of cellulose from the green Cladophora algae and the conducting polymer polypyrrole operating in a water electrolyte.

 

This project encompasses research on a new type of

cellulose-based nanomaterials for novel, efficient and

environment-friendly energy storage devices. The innovative

design of the proposed energy storage systems is based

on the technology of coating individual cellulose fibres by

50-nanometre-thick layers of conductive polymer to obtain a

lightweight, flexible, mechanically robust electrode material

of large surface area with good charge capacity and very

high charging rates. Since the proposed energy storage

devices involve water-based electrolytes and most likely

can be manufactured entirely of non-metal components,

these devices represent a largely unexploited resource for

production of easily-disposable environment-friendly energy

storage systems.

Nano Coatings for Solid Oxide Fuel Cells

The solid oxide fuel cell (SOFC) suffers from an operational lifetime that is far short of commercial requirements. The problem is being tackled in this project. SOFC is important in relation to sustainable development. When compared to other fuel cell technologies, SOFC’s offer unmatched fuel flexibility with the ability to run on everything from pure hydrogen to biodiesel and biogas.

 

This flexibility is made possible by operating in a higher temperature range, between 650 and 800C. Higher temperatures also however mean quicker material degradation, which is where the challenge lies in this project. The goal is to increase the lifespan of the fuel cell. An important component is the so called interconnect that connects individual cells to each other. The sheets are composed of a specially developed stainless steel, on which a nanocoating is then applied.

 

The nanocoatings that the project participants hope to develop will hopefully allow fuel cells to have lifetimes that make them economically attractive.

TOPNANO

TopNANO aims to develop sustainable and efficient methods based on nanotechnology to reduce problems and costs with ice build-up.

 

Ice causes major problems on airplanes, wind turbines and in heat exchangers. Today’s methods using heating and chemical treatments are expensive, can be inefficient and non sustainable. Nanotechnology can create surfaces where the ice does not stick. The aim is to develop sustainable and efficient methods based on nanotechnology to reduce problems and costs with ice build-up.

 

Nanostructured surfaces against ice have never been tested in such a large scale before. It will be a big challenge to make the surfaces dirt repellent and wear resistant in severe environment. The nanotechnology also opens up for new solutions within other industrial sectors/applications where ice buildup creates problems.

Semiconductior nanowire based solar cells NANORDSUN

NANORDSUN is a consortium that aims to find the most energy efficient semiconductor nanowire solar cells with an optimum design solution for low cost.

 

Today Si is the dominating solar material with a market share of about 90% and typical efficiencies of 20%. However, the cost per kWh is still higher than other competing energy sources, which hinders its use as a major source of clean renewable energy.

 

In view that silicon nanowire solar cells have been shown to exhibit efficient light trapping that consequently enables  silicon nanowire solar cells to use only about 1 per cent of the material used in equivalent thin-film silicon solar cells, NANORDSUN’s aim is to focus on the research and development of low-cost and hihgly-efficient III-V semiconductor core-shell radial p-n junction nanowire solar cells.
