Photocatalyst makes hydrogen production 10 times more efficient

Hydrogen is an alternative source of energy that can be produced from renewable sources of sunlight and water. A group of Japanese researchers has developed a photocatalyst that increases hydrogen production tenfold.

Stanford researchers create a better way to predict the environmental impacts of agricultural production

Consumer goods companies often rely on life-cycle assessments (LCA) to figure out the potential consequences of how they design products and source ingredients. This kind of assessment, while sophisticated, often lacks detail about how the products affect natural resources such as land, water and biodiversity.

A team of researchers from Stanford University and the University of Minnesota, in a partnership called the Natural Capital Project, along with researchers from Unilever’s Safety and Environmental Assurance Centre, developed a new kind of assessment to integrate these impacts in a more detailed way. They call it Land Use Change Improved Life Cycle Assessment, or LUCI-LCA. It’s designed to help researchers or companies more accurately predict impacts of new designs and sourcing.

Emergent constraints on projections of declining primary production in the tropical oceans

Emergent constraints on tropical marine primary production increase confidence in a long-term decrease in primary productivity in response to rising sea surface temperatures. The most extreme projected declines in productivity are, however, unlikely.

Flipping the switch on ammonia production

Nearly a century ago, German chemist Fritz Haber won the Nobel Prize in Chemistry for a process to generate ammonia from hydrogen and nitrogen gases. The process, still in use today, ushered in a revolution in agriculture, but now consumes around one percent of the world’s energy to achieve the high pressures and temperatures that drive the chemical reactions to produce ammonia.

Today, University of Utah chemists publish a different method, using enzymes derived from nature, that generates ammonia at room temperature. As a bonus, the reaction generates a small electrical current. The method is published in Angewandte Chemie International Edition.

Frosts kill dozens in central Europe, smog forces production cuts

PRAGUE (Reuters) – Severe frosts and snow storms killed at least 25 people in central Europe over the weekend, mainly in Poland, as temperatures in the region dropped below -30 degrees Celsius in some places.

Cement made from steel production by-product can lead to a huge CO2 reduction

Steel production generates some hundred million tons of steel slag worldwide each year. This giant mountain of leftovers is largely dumped. TU/e professor of building materials, Jos Brouwers, will be working with industrial partners to investigate whether he can make cement out of it. If he succeeds, more CO2 emissions can be cut than is produced yearly by all the traffic in the Netherlands.

Steel slag is produced by the conversion of raw iron into steel – around 125 million tons of it per year. Much of that is dumped and only a small portion used, in embankments. That’s a shame, professor Jos Brouwers says, because the mineralogical composition very closely resembles that of cement. It contains the same components, but in different ratios. And it is public knowledge that the cement industry emits a very high amount of CO2: five percent of the global total. A cement substitute with no extra CO2 emissions would, therefore, be most welcome.

Dirty production of NHS antibiotics in India helping to create superbugs

The NHS is buying drugs from pharmaceutical companies in India whose dirty production methods are fuelling the rise of superbugs, write Andrew Wasley & Madlen Davies. There are no checks or regulations in place to stop this happening – even though the rapid growth in antibiotic resistant bacteria in India is spreading across the world, including to the UK and NHS hospitals.

While global methane emissions are up, study says fossil fuels not the culprit

A new study from NOAA, the National Oceanic Atmospheric Administration, puts a new twist on a tricky question about the impact of increased oil and gas production on greenhouse gas emissions. Scientists have detected increased rates of methane emissions globally since 2007. That uptick corresponds to the rapid boom in U.S. shale gas and shale oil production, and some hypothesized that the two could be connected. But it turns out that the correlation may not necessarily be a cause.
