National Institute of Standards and Technology (NIST) keeps an annual tally of the weights and measures needed for industries throughout the nation’s economy. NIST’s Handbook 44 is like a Whole Earth Catalog for the durable and consumable goods sold in the United States, including gasoline—and now hydrogen. Hydrogen fuel cells weighed in recently to join the U.S. industrial marketplace. And the fuel pumps that would dispense hydrogen to fuel-cell-powered cars can, new research from NIST suggests, live up to the measurement standards U.S. regulators would require.
Hydrogen fuel cells combine molecular hydrogen with oxygen from the air to generate electricity plus water vapor exhaust—making for a powerful electric vehicle propulsion system with zero carbon emissions. But hydrogen is a wily gas, with a molecular weight as light as molecules come. ELI5: Why Tesla's new power wall a big deal. : explainlikeimfive. Meet the scientific accident that could change the world.
Well, going by the video it appears to be have comparable energy density to similarly sized but expensive rechargeable watch batteries.
The key breakthroughs are, I think: 1) How fast it is to charge it. Molten air – a new class of battery. The molten air batteries combine useful characteristics from existing types of batteries © Shutterstock Scientists from the US have invented a new type of battery.
The so-called ‘molten air batteries’ have among the highest electrical storage capacities of all battery types to date. Inexpensive batteries with better energy storage densities are needed for many applications. For example, one barrier to the large-scale adoption of electric cars is the limited distance they can travel before their battery needs recharging. Stuart Licht and his group at George Washington University think their molten air batteries could be the answer. Another important advantage of molten air batteries is that, unlike some other high energy batteries, the molten air battery is rechargeable.

Scientists at Arizona State University have created a lithium-ion battery out of carbon nanotube-coated paper — and then, by folding it like a map, they have increased the battery’s energy density by 14 times. We should probably start with the fact that this foldable lithium-ion battery is made out of paper. As you’ve probably surmised, it’s not possible to bend a conventional lithium battery, because it has numerous rigid parts (the carbon anode, the protective casing). New battery design could help solar and wind power the grid. Researchers from the U.S.
Department of Energy's (DOE) SLAC National Accelerator Laboratory and Stanford University have designed a low-cost, long-life battery that could enable solar and wind energy to become major suppliers to the electrical grid. "For solar and wind power to be used in a significant way, we need a battery made of economical materials that are easy to scale and still efficient," said Yi Cui, a Stanford associate professor of materials science and engineering and a member of the Stanford Institute for Materials and Energy Sciences, a SLAC/Stanford joint institute. "We believe our new battery may be the best yet designed to regulate the natural fluctuations of these alternative energies. " Cui and colleagues report their research results, some of the earliest supported by the DOE's new Joint Center for Energy Storage Research battery hub, in the May issue of Energy & Environmental Science. Donald Sadoway: The missing link to renewable energy.
Power Storage, Missing Link in Path to Renewables, Gets a Mandate in California. Electricity, despite having transformed nearly every aspect of life on Earth, remains a technology with some significant limitations.
More than half of the energy that goes into producing electricity is lost, and even the energy that is successfully converted into electricity is a use-it-or-lose it proposition, so much of it ends up wasted as well. The inability to store electrical power has become more important as the developed world has begun to try to adopt cleaner energy sources, such as solar and wind power. The sun isn’t always shining and the wind isn’t always blowing, but people and factories always need electricity.
But energy storage is getting its mainstream debut in California. The state has mandated that by 2024, its three major utilities provide 1,325 megawatts of storage, roughly equivalent to what one major power plant produces and about a fifth of a percent of what the state used on average per day, according to the most recent state statistics.
