A new study from the Energy Department’s National Renewable Energy Laboratory (NREL) establishes a novel catalytic method to produce renewable acrylonitrile using 3-hydroxypropionic acid (3-HP), which can be biologically produced from sugars. This hybrid biological-catalytic process offers an alternative to the conventional petrochemical production method and achieves unprecedented acrylonitrile yields.

New research at the University of Waterloo could lead to the development of batteries that triple the range of electric vehicles.The breakthrough involves the use of negative electrodes made of lithium metal, a material with the potential to dramatically increase battery storage capacity.“This will mean cheap, safe, long-lasting batteries that give people much more range in their electric vehicles,” said Quanquan Pang, who led the research while he was a PhD candidate in chemistry at Waterloo.The increased storage capacity, or energy density, could boost the distance electric vehicles are able to travel on a single charge, from about 200 kilometres to 600 kilometres.

A team of researchers from the University of Toronto is partnering with the construction industry to help reduce the carbon footprint of buildings, bridges, public transit and other major infrastructure projects.“What we’re building is a decision-support tool that can be used in the early stages of design and planning,” says Heather MacLean, a professor in the department of civil engineering who is one of five Faculty of Applied Science & Engineering professors involved in the project. “Ultimately, the goal is to produce infrastructure with much lower greenhouse gas impact.”

Different low carbon technologies from wind or solar energy to fossil carbon capture and sequestration (CCS) differ greatly when it comes to indirect greenhouse gas emissions in their life cycle. This is the result of a comprehensive new study conducted by an international team of scientists that is now published in the journal Nature Energy. Unlike what some critics argue, the researchers not only found that wind and solar energy belong to the more favorable when it comes to life-cycle emissions. They also show that a full decarbonization of the global power sector by scaling up these technologies would induce only modest indirect greenhouse gas emissions – and hence not impede the transformation towards a climate-friendly power system.

With the power-conversion efficiency of silicon solar cells plateauing around 25%, perovskites are now ideally placed to become the market’s next generation of photovoltaics. In particular, organic-inorganic lead halide perovskites offer manufacturing versatility that can potentially translate into much higher efficiency: studies have already shown photovoltaic performances above 20% across different solar cell architectures built with simple and low-cost processes.

When it is cold in winter, cars tend to have starting problems. This is not much better with electric cars, which inevitably lose capacity of their rechargeable lithium-ion batteries at freezing temperatures. Now, Chinese scientists have offered a strategy to avoid plunging battery kinetics. In a study published in the journal Angewandte Chemie, they designed a battery system with a cold-enduring hard-carbon anode and a powerful lithium-rich cathode, with the important initial lithiation step integrated.
