That trajectory is considerably sooner than Binderbauer described when he took over as CEO in 2017. It would put TAE ahead of two formidable competitors. The 35-nation ITER project expects to complete its demonstration reactor in France in 2025. Vancouver-based General Fusion Inc. is devoting the next five years, with support from the Canadian government, to developing a prototype of its fusion reactor. And the Massachusetts Institute of Technology announced last March that it expects to bring its fusion reactor to market in ten years.

#Swedish research multiplies the life of rechargeable #NiMH batteries

hybrid-battery-nimh-cell

Researchers at #Stockholm University have developed a method to multiply the lifespan of nickel-metal hydride batteries. This means that the batteries can handle a great many more charging cycles without losing capacity. The new method also means that the batteries can easily be restored once they have begun to wear out, unlike other rechargeable batteries that must be melted down for recycling.

Most rechargeable batteries are based on either lead, nickel-cadmium (NiCd) or various combinations with lithium. Batteries based on nickel-metal hydride (NiMH) with an aqueous electrolyte are both eco-friendly and safe. The NiMH battery is developed from the nickel-hydrogen battery (NiH2). It has long been known that (NiH2) batteries have a superior lifespan compared to other battery types. This is why they are (for example) used in satellites in orbit in space, where the batteries must function for decades without servicing. The Hubble space telescope is one example, but NiH2 batteries are also spinning around our neighboring planets. However, these structures of the batteries are impractically large, because the hydrogen is stored in gas tanks. NiMH batteries can be made much more compact, because the hydrogen is stored in a metal alloy/metal hydride with a hydrogen density equivalent to that of liquid hydrogen. Researchers at Stockholm University has now developed a technique by which to achieve the same long lifespan for NiMH batteries as in the large NiH2 batteries.

The inspiration for the new technology came from a new NiMH battery manufactured by Nilar AB in Gävle.

#BBC News – #Climate change: The massive #CO2 emitter you may not know about

_104804187_biggest_cement_producers_976px_v3-nc

Cement is the source of about 8% of the world’s carbon dioxide (CO2) emissions, according to think tank Chatham House.

If the cement industry were a country, it would be the third largest emitter in the world – behind #China and the #US. It contributes more CO2 than aviation fuel (2.5%) and is not far behind the global agriculture business (12%).

#Bolivia’s Almost Impossible #Lithium Dream

2000x-1

One of the world’s poorest nations is sitting on the second-largest amount of the mineral needed to power electric cars.

President Morales nationalized hydrocarbons, #Bolivia’s main source of revenue, as well as the electricity grid and telecoms. He vowed to “industrialize with dignity and sovereignty,” promising that raw #Lithium would not be exploited by foreign corporations but instead processed by state-controlled entities in Bolivia and transformed into batteries. Morales once said he wanted to see “a lithium-powered #Toyota made in Bolivia.”

Waste #CO2 to be turned into ingredients for fuel, plastics and even food

16-MS-2494-EE-Science-Cover_v6-

Report

The recent landmark report from the Intergovernmental Panel on #Climate Change warned that the world needs to limit temperature rise to 1.5°C. This requires many solutions and multiple technologies.

“Since the industrial sector emits 40% of all carbon dioxide, we are trying to capture it from the chimney and do something useful with it,” said Professor Patricia Luis Alconero at #UC #Louvain in #Belgium, who has just begun an ambitious project to turn waste #CO2 into useful chemicals.

Her project, CO2Life, is inspired by nature. “Our process looks at the way nature takes up CO2 for its own ends. We try to copy nature’s use of enzymes, but in a way that is more efficient and which uses membrane technology,” she said.

Current technology for capturing carbon uses liquid amines, expensive and toxic chemicals with great affinity for CO2 molecules, but the cost and sustainability of the process are of concern. In order to generate energy and to capture CO2 in a fossil fuel power plant, for instance, an additional 30% more energy needs to be generated.

Membranes

To develop this membrane-based process, Prof. Luis Alconero is using amino acid salts and enzymes that will capture and convert CO2 molecules into useful chemicals. In a second step, also using membranes, the chemicals will be crystallised and recovered as pure materials for use by industry.

“This process is flexible since depending on the enzymes we use, we can get different chemicals,” she said. Examples include carbonate salts, such as sodium or calcium carbonate, a raw material for the cement industry, or glucose.

Other high-value possibilities are pure compounds that could be valuable to the food industry. It is the cost of turning CO2 into something useful and the value of that material that determines whether the process sinks or swims.

“CO2 is a waste, so it really has to be a cheap process that leads to an interesting component,” said Prof. Luis Alconero, who aims to build a prototype system.

“Our objective is to come up with a solution that is more environmentally friendly than amines and also to solve the economic issues,” she said.

System to rid space station of astronaut exhalations inspires Earth-based CO2 removal

iss057e055227_crp

When astronauts aboard the International Space Station (#ISS) exhale carbon dioxide (CO2), it’s removed from the air and pumped into space. Could an Earth-based version help remove greenhouse gas emissions from our atmosphere?

 

In order to limit global warming to 1.5˚C above pre-industrial levels and avoid some of the worse impacts of climate change, it means eliminating all 42 billion tonnes of annual CO2 emissions by 2050.

One way of doing this is to cut emissions. Another is to design materials that can remove the CO2 that is already in the atmosphere or before it’s expelled. The problem is that no one has quite worked out how best to do this – yet.

The air filter system in space inspired Professor Stefano Brandani and Dr Giulio Santori from the University of Edinburgh, UK, to develop a way of capturing and concentrating CO2 directly from the atmosphere. This ambitious strategy – to build a so-called artificial tree – would see CO2 captured to be stored in large underground reservoirs.

Zeolite

The CO2 breathed by astronauts aboard the ISS is captured by using a sponge-like mineral called a zeolite, which has tiny pores to lock in a CO2 molecule. On the space station, the zeolites empty their CO2 when exposed to the vacuum of space.

As part of a project called ACCA, Dr Santori is hacking the system so it will work on Earth. This is more challenging. ‘There is so much more CO2 to capture and concentrations are more dilute to begin with on Earth, so it is much more energy intensive,’ he explained. ‘The starting concentration of CO2 on the ISS is one order of magnitude higher.’

Membranes

The idea is to install membranes that trap CO2, which can then be concentrated and compressed for storage. ‘Membranes are efficient and can save energy compared to other systems,’ said Professor Marco Giacinti Baschetti at the University of Bologna, Italy.

In traditional strategies used by industries such as coal plants, CO2 is captured in special liquids or solid sponge-like structures, but these must then be heated up to release the CO2. This is not needed with membranes. All existing technologies, however, are costly. Current membrane materials are not durable enough and do not separate CO2 well enough to be economically sensible.

Prof. Baschetti runs a project called NANOMEMC2 which is developing a number of different membranes for CO2 capture. In November, the team is to test a new membrane in a Colacem cement facility in Italy.

Developed by project scientists at the Norwegian University of Science and Technology, the membrane is made of hollow fibres, about a millimetre thick, and covered with an extremely thin layer of nanocellulose and polymer mixed with artificial amino acids. The nanocelluose, which is made of miniscule fibres from wood, allows CO2 to permeate, while blocking other gases. The amino acid grabs onto CO2 and pulls it across the membrane.

#Chinese #Nickel demand to increase, but build-up in capacity to cap prices

1484198364401

Chinese nickel demand from stainless steel and battery materials producers will continue to rise in near future, although extensive investments in nickel projects will cap higher nickel prices.

The growth in battery materials production led by expectations of a boom in electric vehicles (#EVs) will also drive higher #Nickel consumption.

“#China produced 100,000 tonnes of ternary battery materials in 2017, up 100% from 2016; meanwhile, production is expected to rise about 30% in 2018,” Xu Aidong, chief analyst at Beijing Antaike, said.

As a result, there has been  aggressive investment by #Chinese producers in new nickel projects, especially in #Indonesia, in order to secure the resources for these two areas of growth.

Most recently, Chinese #Cobalt producer Huayou Cobalt announced in November it is to invest in a joint venture with other four companies to build a laterite ore hydrometallurgy plant producing nickel intermediate products in Morowali, Indonesia.
