Battery idea: Hydroelectric pumped storage, but with bricks

December 11th, 2018 at 12:26 pm » Comments Off

Company called Energy Vault has an agreement to build a pilot tower in India in 2019. A mock-up of what Energy Vault’s tower looks like. Energy Vault A company called Energy Vault has proposed a new utility-scale battery that is both old and new at the same time. The “battery” is mechanical, rather than chemical, […]



Natural gas firms have a proposal to convert home heating to hydrogen

December 7th, 2018 at 1:18 am » Comments Off

Three companies want to test out a pilot project in Northern England by 2028. Three natural gas distributors issued a report this week detailing plans to convert the UK’s residential gas system to a hydrogen delivery system. UK firms Northern Gas Networks and Cadent, as well as Norwegian gas firm Equinor, wrote that the proposal […]



Scientists develop liquid fuel that can store the Sun’s energy for up to 18 years

November 13th, 2018 at 11:26 am » Comments Off

No matter how abundant or renewable, solar power has a thorn in its side. There is still no cheap and efficient long-term storage for the energy that it generates. The solar industry has been snagged on this branch for a while, but in the past year alone, a series of four papers has ushered in […]



The future of construction may be concrete that generates its own electricity

November 8th, 2018 at 11:40 am » Comments Off

We need buildings in which to live, but crafting those buildings is making it harder to live on this planet. As much as 10% of global carbon emissions come from the production of concrete. One ton of CO2 is generated by making one ton of cement, which is made from limestone and a few other […]



120-kW wireless charging proves 97% efficient

October 29th, 2018 at 8:49 am » Comments Off

High power wireless charging efficiency reaches 97%. The Department of Energy’s Oak Ridge National Laboratory (ORNL) upgraded its previous 20 kW wireless charging system to 120 kW, and through a new design and a silicon carbide power electronic device, it was able to achieve 97% efficiency.



Scientists turn nuclear waste into diamond batteries

October 24th, 2018 at 9:50 am » Comments Off

They’ll reportedly last for thousands of years. This technology may someday power spacecraft, satellites, high-flying drones, and pacemakers. Nuclear energy is carbon free, which makes it an attractive and practical alternative to fossil fuels, as it doesn’t contribute to global warming. We also have the infrastructure for it already in place. It’s nuclear waste that […]



This new Lithium battery tech can simply suck up CO2 to power itself

October 8th, 2018 at 11:48 am » Comments Off

We need this right now! Everybody knows the world’s got a serious carbon dioxide problem, but an ingenious and potentially cost-effective way of dealing with our surplus CO2 could provide the means of tomorrow’s battery technology. For years scientists have looked at ways of capturing carbon and storing it underground or even potentially in the […]



Utilities have a problem: the public wants 100% renewable energy, and quick

September 18th, 2018 at 9:06 am » Comments Off

The industry is groping for ways to talk the public down. Renewable energy is hot. It has incredible momentum, not only in terms of deployment and costs but in terms of public opinion and cultural cachet. To put it simply: Everyone loves renewable energy. It’s cleaner, it’s high-tech, it’s new jobs, it’s the future. And […]



Study: Decentralized microgrids can provide 90% or a neighborhood’s energy needs

September 16th, 2018 at 9:45 am » Comments Off

“The new approach could even pave the way for 100 percent self-sufficiency in power, heat, and water.” A new report funded by the Dutch government finds that microgrid technologies could make a local “techno-economy” 90 percent self-sufficient, through the decentralized sharing of energy at the local level between multiple households. This report adds fuel to […]



This astrophysicist explains the surprisingly complex concept of ‘nothing’

August 27th, 2018 at 10:18 am » Comments Off

Philosophers have debated the nature of “nothing” for thousands of years, but what has modern science got to say about it? In an interview with The Conversation, Martin Rees, Astronomer Royal and Emeritus Professor of Cosmology and Astrophysics at the University of Cambridge, explains that when physicists talk about nothing, they mean empty space (vacuum).
