Heating Buildings With Solar Energy Stored in Sand

Cars That Think

In a region known for long, dark winter nights, Polar Night Energy is building a system in the city of Tampere that can heat buildings with stored solar energy — all day, all night, and all winter long. This means that storing and distributing energy is as important as its generation. The apparent contradictions do not end there.

Blue World Technologies takes 15% stake in Danish Power Systems; methanol fuel cell vehicles

Green Car Congress

A closed thermal integration enables reuse of fuel cell waste heat for fuel evaporation thereby increasing efficiency. In the combination with HT PEM the waste heat is of sufficient temperature to drive this process, meaning an energy-free process which leads to a superior overall efficiency.

Russian researchers develop wasteless joint processing of electric furnace and ladle slag to produce pig iron and clinker

Green Car Congress

Scientists of Ural Federal University and the Institute of Metallurgy of the Ural Branch of RAS (Russian Academy of Sciences) have developed and successfully tested the technology of joint non-waste processing of electric furnace and ladle slag to obtain pig iron and Portland cement clinker. —Oleg Sheshukov, lead author. Background.

Thermal Energy Storage Is No Longer Just Hot Air

Cars That Think

The company is building these shipping container systems, which work like giant batteries that store energy as heat and pressurized air , rather than a chemical reaction (Cheesecake’s name is derived from a nerdy acronym for their technology.) The compressed air, now cool and easier to store, is housed in a large air tank.

Oleophobic hydrophobic magnetic sponge selectively soaks up oil, sparing water and wildlife

Green Car Congress

And sorbents are not only expensive, but they generate a huge amount of physical waste—similar to the diaper landfill issue. The nanocomposite’s nanoporous 3D structure selectively interacts with and binds to the oil molecules, capturing and storing the oil until it is squeezed out. —Vikas Nandwana.

Molten-Salt Battery Freezes Energy Over a Whole Season

Cars That Think

Molten-salt batteries , as the name implies, use a liquid, molten-salt electrolyte, which freezes at room temperature, allowing the batteries to be stored in an inactive state. An important one, Sprenkle adds, is understanding the value of that stored energy. “A He expects the battery to retain over 80% of its charge in that period.

QUB spin-out to commercialize to technique for production of MOFs; storage for natural gas vehicles

Green Car Congress

By simply grinding together two cheap precursors in a basic milling machine, the MOF material is produced in a matter of minutes, in a powder form, ready for applications without further treatment, and without generating solvent waste. —Prof. There are an abundance of sites where gas molecules can adsorb to the material.
