A Montana-based clean energy programmer

A Montana-based clean energy programmer described his proposed pumped hydropower factory as “two lined swimming pools connected by a pipe”. Could this possibly be the important to reducing our gas dependency? California seems to consider so.

Earlier this season, California’s Public Utilities Payment (CPUC) released planning advice for utilities. It suggests we add these resources to our grid inside the coming decade.
In addition to your big increase in the power of sunshine and battery storage including a modest increase in breeze, we see a first-time requirement of “long-duration storage”. Traditional lithium-ion batteries can provide energy for some hours, but this type of storage was designed to last for most of your day.
As solar and wind displace gas about our grid, we must handle extended cloudy or even windless periods. The graph below (highlighted in a recent talk by prior Secretary of Energy Steven Chu) illustrates this general relationship. When a grid has a relatively low penetration of renewables (e. f.,less than 40-50%), short-duration storage like batteries suffices to repay gaps in renewable energy. For grids up in order to about 80% penetration, storage for up to a day’s worth of energy is required. That is where solutions like pumped hydropower come in.
Pumped storage hydropower (PSH) is a pretty simple technology. When renewable energy is ample, water is pumped uphill from a lower reservoir to a strong upper reservoir. When replenish-able energy is scarce, mineral water flows downhill, spins any turbine, and generates electric power. The effect is never to create energy. In simple fact, these facilities are world wide web consumers of energy. But start by making renewable energy available when it can be most needed, PSH helps renewables better match require, reducing the need for gas for the grid.
The greater the height difference between the 2 reservoirs, and the bigger the pipes (aka penstocks), the more power can be made. The bigger the reservoirs, the greater energy can be produced (the longer the power can last). These facilities may be pretty flexible. Newer ones can switch between generating hardly any power for a long period or a larger amount for a reduced period. And most can certainly switch between pumping and generating energy in seconds, reacting quickly to changes widely used. Moreover, they are very efficient, generating about 80% in the energy that they eat. This isn’t new. Pumped hydropower has been around since the overdue 1800s, but it took off in the united states in the 1960s and 1970s with the development of large, inflexible coal and also nuclear power supplies.
The flexible hydropower resource was ramped up and down to better meet the actual demand curve. Today it serves the same purpose, helping to fill in gaps when our inflexible renewables flunk. You can see how that works inside the chart below. This method of flexible hydropower makes up around one-third of Palo Alto’s strength supply.
Today over 95% of electricity storage the united states is by using pumped hydropower, but there’s just not very much of it. The 40-odd facilities we now have cover only 2% (22GW) associated with our total power capability (1 TW). (5) It’s not for lack of trying. The Department of Electrical power reports that 55 new PSH projects were from the development pipeline at the end of 2018, totalling concerning 30 GW.
