Research project seeks solutions for profitable algae production – great potential for climate change mitigation

A two-year research project aims to overcome technical difficulties in large-scale algae cultivation, a promising method for climate change mitigation. The ROBA project focuses on developing economically feasible algal cultivation processes using advanced measurement technologies and bioprocess engineering.

Disposable electronics on a simple sheet of paper

Scientists have developed a prototype circuit board made of a sheet of paper with fully integrated electrical components, making it easy to dispose of responsibly. The new design uses wax and ink to print channels, conductive inks, and metal components onto the paper, creating a flexible and thin device that can be burned or degraded.

Load up the hydrogen but hold the carbon

A Kyoto University-led team has created a novel hydrogen plant design that harnesses fully renewable resources to produce clean hydrogen with minimal associated CO2 emissions. The SABI-Hydrogen system uses solar heating and biomass gasification to produce hydrogen, resulting in an emission rate of only 1.04kg CO2/kg hydrogen produced.

Studying the fabrics of the past to understand the ageing of the eco-materials of the future

The study of four Baroque-era paintings reveals that flax fibres from fabrics a few hundred years old have undergone more degradation than those from thousand-year-old Egyptian mortuary linens. The researchers used various high-resolution optical analysis methods to analyse the fibre structure without degrading the samples.

100% renewable energy using building science

Researchers found that combining resource diversification, excess generation, building efficiency, and demand flexibility can reduce or eliminate long-duration energy storage in some regions. This approach enables the achievability of a fully renewable system with technology building blocks accessible today.
