James Temple, writer for MIT technology Review: Fluctuating solar and wind power require lots of energy storage, and lithium-ion batteries seem like the obvious choice—but they are far too expensive to play a major role. Relying on renewables alone significantly inflates the cost of overhauling energy. At current prices, a battery storage system of that size would cost more than $2.5 trillion. Repeat that every time the batteries are worn out.
Richard McPherson, electrical power and grid security expert: America is now living with a horrible electricity supply system. At the same time the nationwide system is vulnerable to the effects of weather, humans, EMP and solar events. A situation created by politicians for their benefits. A system, China, Russia, North Korea and their proxies love.
Jack Ponton, Emeritus Professor of Engineering at the University of Edinburgh, Fellow of the Royal Academy of Engineering: Most renewable energy enthusiasts now seem to understand that powering a modern society will require something else in addition to intermittent electricity generation. The currently fashionable ’something else’ is storage. This paper will discuss storage technologies, Britain’s current facilities and what might be needed to provide reliable power from wind, solar and tidal generation. There seems to be no possibility that any existing storage technology can handle the intermittency of wind generation. Solar plus battery storage is probably already cost-competitive for locations in or near the tropics, where year-round load factors are acceptable and so only overnight storage is required. In the UK, low winter load factors mean that essentially no useful generation takes place in December and January.
Michel Gay: Oui, l'humanité peut gérer les déchets nucléaires. Aujourd'hui, il n’y a plus de verrou scientifique ou technique qui empêcherait une gestion sûre et définitive des déchets de haute activité dans un stockage en formation géologique profonde.
James Conca, Geochemist: In January, 2017, the U.S. House of Representatives passed the Advanced Nuclear Technology Act of 2017, HR 590, that is intended “to foster civilian research and development of advanced nuclear energy technologies and enhance the licensing and commercial deployment of such technologies. At the same time, the latest version of the Interim Consolidated Storage Act was introduced in the House. This bill would create one or more interim storage facilities to hold spent nuclear fuel (SNF) from all the nation’s nuclear power plants and would allow the Energy Department to contract for temporary used nuclear fuel storage facilities. These bills address two of the most important recommendations made in 2011 by then President Obama’s Blue Ribbon Commission on America’s Nuclear Future (the BRC),”
