Rhodium Group estimates US GHG fell 2.1% in 2019, driven by coal decline

Green Car Congress

Emissions from buildings, industry and other parts of the economy rose, though less than in 2018. All told, net US GHG emissions ended 2019 slightly higher than at the end of 2016. Natural gas generation made up much of the gap last year, as it has consistently in recent years, due to extremely cheap gas prices. year-on-year.

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.) That’s why Liu’s Thermal Energy Storage Group at ORNL is focused primarily on buildings.

Bloomberg NEF forecasts falling battery prices enabling surge in wind and solar to 50% of global generation by 2050

Green Car Congress

BNEF predicts that lithium-ion battery prices, already down by nearly 80% per megawatt-hour since 2010, will continue to tumble as electric vehicle manufacturing builds up through the 2020s. Coal emerges as the biggest loser in the long run. —Elena Giannakopoulou, head of energy economics at BNEF.

Further, SpaceX has only lost one booster to waves, and it solved that problem by developing a relatively cheap robot. Jeff Bezos publicly revealed New Glenn just a few weeks before CEO Elon Musk’s long-planned September 2016 reveal of SpaceX’s next rocket, then known as the Interplanetary Transport System (ITS).

Tony Fadell: The Nest Thermostat Disrupted My Life

Cars That Think

For most of the 10 years that I idly thought about thermostats, I had no intention of building one. Adapted from the book BUILD: An Unorthodox Guide to Making Things Worth Making by Tony Fadell. But the technology that I needed to make it happen—reliable low-cost communications, cheap screens and processors—didn’t exist yet.

Stanford, SLAC team cages silicon microparticles in graphene for stable, high-energy anode for Li-ion batteries

Green Car Congress

This new method allows us to use much larger silicon particles that are one to three microns, or millionths of a meter, in diameter, which are cheap and widely available. Now the team will work on fine-tuning the process and on producing caged silicon particles in large enough quantities to build commercial-scale batteries for testing.
