Lessons from a year with solar power

EV Info

It was one year ago that we decided to add solar panels to our roof. In other words, power is energy per unit of time. Power is watts. In March 2020 we installed 9 solar panels an inverter and 2 battery packs. Panels: JA Solar black. Simply put the more sun the more power. Energy is watt-hours.

Australia Goes All-in on Green Hydrogen

Cars That Think

The carbon-free rigs will pack 50 kilos of hydrogen zapped from water using electricity from the refinery’s dedicated solar power plant. And while coal plants still supplied over half of Australia’s power in 2021, change is afoot. Welcome to Australia, where a green-hydrogen boom is in full swing.

Stanford study quantifies energetic costs of grid-scale energy storage over time; current batteries the worst performers; the need to improve cycle life by 3-10x

Green Car Congress

As the percentage of electricity supply from wind and solar increases, grid operators will need to employ strategies and technologies, including energy storage, to balance supply with demand given the intermittency of the renewable supply. Their results are published in the RSC journal Energy & Environmental Science.

How Smart EV Charging Will Help Promote Renewable Power Generation

Wallbox

The proportion of grid electricity generated by renewables such as wind and solar energy fluctuates depending on how hard the wind is blowing or how strong the sun is shining. This can lead to a huge variation in the grid power available, which can be a problem for power companies. The EV as a mobile electricity storage device.

Wind-to-Hydrogen Tech Goes to Sea

Cars That Think

Wind and solar parks produce a large portion of their energy. Then, as now, wind farms are operating off the world’s coasts—but not all of these offshore sites are connected to the mainland via underwater power cables. Airplanes, for example, won’t be able to fly long distances on battery power.
