Artificial intelligence solves Schrödinger’s equation

Posted by in categories: chemistry, information science, mathematics, particle physics, quantum physics, robotics/AI, space

A team of scientists at Freie Universität Berlin has developed an artificial intelligence (AI) method for calculating the ground state of the Schrödinger equation in quantum chemistry. The goal of quantum chemistry is to predict chemical and physical properties of molecules based solely on the arrangement of their atoms in space, avoiding the need for resource-intensive and time-consuming laboratory experiments. In principle, this can be achieved by solving the Schrödinger equation, but in practice this is extremely difficult.

Up to now, it has been impossible to find an exact solution for arbitrary molecules that can be efficiently computed. But the team at Freie Universität has developed a deep learning method that can achieve an unprecedented combination of accuracy and computational efficiency. AI has transformed many technological and scientific areas, from computer vision to materials science. “We believe that our approach may significantly impact the future of quantum ,” says Professor Frank Noé, who led the team effort. The results were published in the reputed journal Nature Chemistry.

Central to both quantum chemistry and the Schrödinger equation is the —a mathematical object that completely specifies the behavior of the electrons in a molecule. The wave function is a high-dimensional entity, and it is therefore extremely difficult to capture all the nuances that encode how the individual electrons affect each other. Many methods of quantum chemistry in fact give up on expressing the wave function altogether, instead attempting only to determine the energy of a given molecule. This however requires approximations to be made, limiting the prediction quality of such methods.

New nanomaterial helps obtain hydrogen from a liquid energy carrier, in a key step toward a stable and clean fuel source

Posted by in categories: chemistry, economics, nanotechnology, particle physics, sustainability, transportation

Hydrogen is a sustainable source of clean energy that avoids toxic emissions and can add value to multiple sectors in the economy including transportation, power generation, metals manufacturing, among others. Technologies for storing and transporting hydrogen bridge the gap between sustainable energy production and fuel use, and therefore are an essential component of a viable hydrogen economy. But traditional means of storage and transportation are expensive and susceptible to contamination. As a result, researchers are searching for alternative techniques that are reliable, low-cost and simple. More-efficient hydrogen delivery systems would benefit many applications such as stationary power, portable power, and mobile vehicle industries.

Now, as reported in the journal Proceedings of the National Academy of Sciences, researchers have designed and synthesized an effective material for speeding up one of the limiting steps in extracting from alcohols. The material, a , is made from tiny clusters of nickel anchored on a 2-D substrate. The team led by researchers at Lawrence Berkeley National Laboratory’s (Berkeley Lab) Molecular Foundry found that the catalyst could cleanly and efficiently accelerate the reaction that removes hydrogen atoms from a liquid chemical carrier. The material is robust and made from earth-abundant metals rather than existing options made from precious metals, and will help make hydrogen a viable energy source for a wide range of applications.

“We present here not merely a catalyst with higher activity than other nickel catalysts that we tested, for an important renewable energy fuel, but also a broader strategy toward using affordable metals in a broad range of reactions,” said Jeff Urban, the Inorganic Nanostructures Facility director at the Molecular Foundry who led the work. The research is part of the Hydrogen Materials Advanced Research Consortium (HyMARC), a consortium funded by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy Hydrogen and Fuel Cell Technologies Office (EERE). Through this effort, five national laboratories work towards the goal to address the scientific gaps blocking the advancement of solid hydrogen storage materials. Outputs from this work will directly feed into EERE’s H2@Scale vision for affordable hydrogen production, storage, distribution and utilization across multiple sectors in the economy.

Inside JET: The world’s biggest nuclear fusion experiment | On Location

Posted by in categories: nuclear energy, sustainability

Inside these walls, scientists have been trying for decades to create an unlimited source of energy, nuclear fusion. Welcome to JET, the world’s biggest nuclear fusion experiment.

Scientists argue that fusion could replace coal gas and nuclear fission in the energy mix alongside renewable energy, which can prove to be unreliable. If we can learn to control it, nuclear fusion could change life as we know it. But that’s a big if.

‘We think we’ve found the answer’: The ‘Supercell’ that could bring safe energy storage to New York

Posted by in categories: business, energy

New York has among the world’s tightest rules on fire safety and regular readers of this site will be aware that that has had a big impact on the ability to site lithium-ion based battery energy storage systems (BESS) within the boundaries of the state’s urban regions.

While the development of large-scale systems is taking place in less densely populated upstate areas of New York, commercial and industrial (C&I) battery storage, which has been used elsewhere around the country to help businesses manage their energy costs and the wider network to adopt greater shares of renewables, has not really been able to gain a foothold.

A couple of weeks ago the New York Power Authority (NYPA) — a public-benefit corporation which serves around 25% of the state’s electric load — began trialling an energy storage system using lithium batteries based around start-up Cadenza Innovation’s ’Supercell’ architecture. Wrapping individual cells into a protective housing, the technology is a low-cost way to prevent thermal runaway from cascading through a battery rack and causing fires.
