England’s Highview Power has contracted with U.S. energy developer Tenaska to pursue gigawatt-hour scale cryogenic energy projects in the U.S. Highview reports a storage cost of $140/MWh at industrial scale; the firm currently operates a 5 MW pilot facility in England.
The investment from Copenhagen Infrastructure Partners suggests that new pumped hydro storage projects can compete with battery storage. Construction of the 400 MW, 3400 MWh facility could begin as early as next year.
Interconnection requirements for mid-sized and large inverter-based systems directly connected to the transmission grid may change based on new guidance issued in draft form by the North American Electric Reliability Corporation. The guidance does not apply to distributed PV.
In an annual report card on North America’s grid reliability, coal and gas are sent to the principal’s office, while solar gains operating guidance related to 2016 and 2017 wildfire-related outages. Texas is cautioned for its lower-than-desired reserve margin, although that was not a problem in 2018.
Solar, wind and storage would take the place of 150 proposed gas-fired generators in a Beyond Carbon campaign launched by Michael Bloomberg and the Sierra Club. Building on the success of the Beyond Coal campaign, Beyond Carbon aims to stop new gas-fired generators, while continuing to retire coal units.
Even if your car is baking in the hot summer sun, you can imagine it staying cool under one of these solar carports recently built all across the country. Technologies include prefabricated framing, double cantilever canopies, and water management systems.
Senator and Presidential candidate Elizabeth Warren calls for “big and bold investments in American research, American industry, and American workers” to counter climate change.
A Science journal article describes how to reach “a future with ~10 terawatts of PV by 2030 and 30 to 70 terawatts by 2050, providing a majority of global energy.”
The pioneering firm Griddy says that its real-time pricing app shows customers when they can use more low-priced solar and wind power, while saving money in the process. An investment from EDF Group will help Griddy expand its reach to the New York and PJM grid regions.
