New energy-efficient manufacture of perovskite solar cells that rivals silicon solar cells

‘Perovskite solar cells’ (PSCs) are less costly than conventional silicon solar cells, but one of their key components is energy-intensive to manufacture as high temperatures are needed. Now researchers have identified new alternative materials for this component which cut energy demands as they can be produced at low temperatures.

Potential health risks from different forms of nanosized cellulose crystals

A new study has found evidence for lung toxicity of different forms of ‘cellulose nanocrystals’ (CNCs) in mice. The study suggests that physical characteristics, such as length, of the CNC relates to the type of effect it has on the lung. These nanosized crystals, made from plant-derived materials, are increasingly being used in novel applications, such as cleaning up oil spills in water and flexible electronic displays, and consumer products, which raises concerns about their potential health impacts.

Solar panel silicon recovery methods tested

A three-step chemical process could successfully recover high-purity silicon from recycled photovoltaic (PV) solar panels, new tests show.

Reducing avian collisions with wind turbines

Wind is an important renewable energy source for Europe. The wind power capacity installed in 2014 could produce enough electricity to meet over 10% of the EU’s electricity consumption. However, wind power structures can also be harmful to birds, which can collide with turbines. This study assessed methods of reducing avian collisions with wind turbines and makes several practical recommendations.

Seals avoid wind farms during the noisiest phase of construction

Wind farms are an important component of Europe’s shift towards a greener energy supply, but they could potentially have an impact on marine ecosystems. This study provides the first measurements of the distribution of harbour seals in relation to the construction and operation of wind farms, and makes recommendations to minimise any potential harm, including breaks in the pile-driving phase of construction.

Which new low-carbon technologies can be developed and commercialised quickly? New research offers analysis

A new study provides clues as to which innovative low-carbon technologies will successfully get onto the market quickly. The historical analysis of 16 energy technologies — from steam engines to wind power — found that the average length of a product’s ‘formative phase’ is 22 years. This important period of innovation in a technology’s development is shorter for products which do not need extensive new infrastructure or changes to user behaviour. The findings could help policymakers identify new technologies that can be deployed more rapidly to meet short-term environmental targets.

A carbon-free future for the Canary Islands possible by 2050

The Canary Islands have the potential to become carbon neutral by 2050, a new study indicates. This could be achieved by shifting to a 100% renewable energy supply, improving energy efficiency and building new grid connections between islands. Energy solutions for small island regions, such as the Canaries, could act as role models for larger systems, as well as similar islands, the researchers suggest.

New soil-sensing method enables more detailed, rapid and efficient environmental monitoring of soil carbon stocks and condition

In-depth soil information is increasingly required to achieve an array of environmental and economic goals. In particular, accurate estimates of soil carbon stocks are necessary to guide land-management practices and climate- related policymaking. To help meet this need, Australian scientists have developed a new sensing method to analyse cylindrical soil samples (soil cores), known as the Soil Condition ANalysis System (SCANS). By integrating a novel automated soil- core sensing system (CSS) with advanced statistical analytics and modelling, the SCANS provides a level of detail that is difficult to achieve with existing alternatives. SCANS is not only rapid, accurate and inexpensive1, but is likely to be a useful tool for farmers, land managers and policymakers, as the improved assessment of soil functions, structures and carbon stocks will facilitate more informed, sustainable decision-making.

Closing the loop on critical materials for renewable energy tech: 10 key factors

A new study lists 10 factors to help create a closed-loop supply chain for critical materials. However, interviews with key actors in supply chains for photovoltaic (PV) panels and wind turbines suggest that manufacturers and recyclers hold different perspectives on these factors. The research highlights the importance of cooperation between supply-chain actors, as well as investment in technologies and infrastructure for closed-loop supply chains.

Wave farms could help prevent coastal erosion under future sea-level rise

As well as providing renewable energy, wave farms can help protect coasts against erosion by reducing the force of waves. However, it remains unknown whether they can provide this complementary service under future climate change when sea levels will be higher. A new study, based upon computer simulations, concludes that a wave farm off the south coast of Spain could indeed protect the coastline under higher sea levels, and cause the local beach to grow in size after storms.

Changes in European sulphur dioxide, nitrogen oxides and CO2 emissions since 1960

Emissions of sulphur dioxide (SO2) and nitrogen oxides (NOx) have fallen significantly across Europe since 1960. According to recent research, this is caused by a combination of factors including improved energy efficiency, a changing fuel mix and specific emission control measures. At the same time CO2 emissions have only increased moderately, mainly due to improvements in energy efficiency.

Kerbside waste-collection schemes may need optimisation, highlights Portuguese study

A new analysis of waste recycling systems in Portugal highlights where kerbside (edge of pavement) collection systems could be optimised, to decrease their environmental impact. In this case, researchers found that the kerbside system was less favourable economically and environmentally due to more packaging and more fuel consumption per tonne of waste, compared to a system where recyclable materials are deposited by residents in large containers. But the researchers suggest that measures such as re-usable boxes and efficient collection routes could help to mitigate the impact of kerbside collection. While there is an environmental impact from waste collection, processing and disposal, this study only focused on the collection phase.

Links between obesity, physical activity, transport and CO2 emissions

A new UK study suggests that there are associations between obesity, physical activity, and levels of CO2 emissions from transport.

They may also partly reflect less ‘active travel’ by bicycle or walking by obese people.
