The Problem With Renewable Energy (and how we’re fixing it)

February 12, 2020

For a few hours in May 2016, for the first
time in more than a century, Britain was burning zero coal to generate
electricity. None at all. All the coal-fired power plants
were turned off. And this here is one of the reasons why. Welcome to the Griffin Wind Farm in Scotland. 68 turbines, more than 150 megawatts of capacity. And the turbines rotate and trim the blades
to track the wind in real time. At full output, this can power entire cities
just from the wind. But as the world moves to renewable energy, we’ve got a little bit of a problem. Because coal, oil, gas, and nuclear stations
are basically just giant boilers. They take water, they heat it up,
that turns to steam, the steam gets forced through a massive turbine
which rotates and generates power. When I say turbine, I don’t mean like the
blades here, I mean hundreds of tonnes of steel rotating
thousands of times a minute. And all those turbines, all around the grid, rotate in sync with each other. After gearing, they all move at
50 cycles a second. 60 in America. All perfectly in time: one slows down, they
all slow down. One speeds up, they all speed up. And that is what stops your lights
from constantly flickering. Because electricity supply has to always match
demand, pretty much exactly. There isn’t a battery in the world big enough
to store power on a national scale. So if a power station suddenly falls off the
grid for some reason, then where’s that supply going to come from? And the answer is the kinetic energy that’s
already in those turbines, in that spinning thousands of tonnes of steel
around the country. Homes and factories will literally suck the
kinetic energy out of that turbine to cover the gap, starting to slow it down. But that won’t cause a problem
for 60 seconds or so, and in that time the National Grid
Control Centre will, I don’t know, throw another nuclear rod on the barbie and up the power output from other stations.
They’ll cover the demand. But, well, that relies on
having enough rotational mass, enough system inertia, as it’s called. And here, in this turbine? Well, you can see. There’s no hundreds of tonnes
of spinning steel, just some blades, a bit of metal, and some circuitry that feeds the power into
the grid at the right frequency. If the whole grid were running on
just wind and solar, there’s no rotational mass.
There’s no grid stability. The minute that supply and demand mismatch,
breakers would trip, and the whole thing would fall apart. Now there are some
possible solutions to this. Pumped hydro storage
has been around for a while, which is where you have two lakes
at different heights. When you’ve got too much power,
you pump water up, and when you’ve got not enough, you drop
it back down again through generators. But that takes seconds or minutes
to kick in. There’s also some experiments going on with
things like molten glass storage, compressed air storage, and flywheels, but they’re all experimental at the minute
and not particularly efficient. The actual solution may come from somewhere
a little unexpected. Because yes, wind is replacing coal and oil, but it’s also replacing petrol, the gasoline
that you put in your car. And as more and more and electric cars
get connected to the grid, well, you’ve got a load of quite large batteries
with computers. Your car could sell power
back to the grid in real-time, second by second, as it’s needed. Combine that with smart appliances and meters
that can watch the grid and work out when would be the best time to
turn on your air-conditioning and fridge is, and you have a grid that does
a lot of the balancing itself. Yes, we will probably always need a
turbine somewhere, some big spinning mass of steel to cover
the little glitches second to second, but the solution to balancing a power grid
is not what we thought it was 20 years ago. It’s not big, monolithic batteries. It’s millions of small ones
up and down the country. Thank you very much to all the team from SSE who have helped get me, and my team,
up on top of this wind turbine. I am incredibly grateful. They have gone above and beyond to help out,
so please, have a look at the links in the description
for more about them, and about the Griffin Wind Farm. [Translating these subtitles? Add your name here!]

    We are using virtually no coal now in 2019 because it has been replaced with gas. On two days in June there was no wind, and all it could muster well below 1% of demand. Even so no coal was used, but gas was producing more than 50%. You can watch the grid every day now and see as wind goes up, gas goes down, and vice versa.

    Cannot say that I agree that the future is car batteries.
    Tesla installed a massive mains battery in South Australia and it's the best thing to have happened for the South Aus and national grids.
    The uptake time for the battery is some fractions of a second from zero load to maximum.
    It is also solar/wind charged so costs are very small compared to coal. We don't have nuclear power in Aus….

    This video needs to be watched by the Smart meter "deniers" who think that smart meters are the work of the devil and that they only benefit the big power companies. Well their purpose is to help balance the grid by offering tariffs which albeit are more expensive at peak times but will be extra cheap at low demand times. The steel industry has had these tariffs for years including a near instantaneous load shedding system for electric arc furnaces.

    A better solution than using EVs as storage and having them put power back into the grid would be to just convert excess energy into chemical fuel and sell that.

  • Reply Gary Lewis September 6, 2019 at 4:48 am

    if we need 1Gw base load power from wind then at a capacity factor of 33% and a 100% storage efficiency then 3Gw of wind power is needed so the 1Gw is supplied to the grid while 2Gw goes to storage. When the wind is not blowing 66% of the time power comes from storage to supply the grid. This means on a 3 day cycle day 1 the wind is blowing day 2 & 3 it is not. but on day 4 if the wind is not blowing then there is no power at all. If storage comes from car batteries then you do not have power to drive home or to work. meaning the size of the battery for the car needs to be a lot larger then it needs to be. So when you drive home you can not power the grid. The cost of the car would be a lot higher because of the needed extra storage. So one would be better off haveing a fixed battery storage building keep the cars light as possable. Otherwize you would have to let your car sit there supply the grid with power and have no power left to drive home.
    Car battery storage to supply the grid
    WILL NOT WORK. sorry.

    So, when the wind stops, it'll suck the charge out of your car. Then what? Call an uber? More likely than not, it'll be petrol powered since full time availability and on demand response is required. Imagine being at work, coming out in the dark, and you haven't got enough charge to make it home! Worse, since it is night time, all the power generated is going into homes, so you can't charge until there is surplus the next day! How silly!

    Of course, you argue, the smart car won't let itself get fully discharged. Really? Can you imagine that electric car owners don't want to take that chance, so they won't connect to charging stations while at work. But then, it wouldn't be in anyone who is alive now lifetime when we have a one for one charging stations to vehicles ratio. Did I just convince myself that this was the most disengenuos report ever told?

You fail in your little bout of self importance in the video in that wind can not ever be relied on even with one lump of metal spinning to help it but the lumps of spinning metal can be relied on with out wind, which is a good job as there seem to be a lot of dead turbines around or are they waiting for the right kind of wind.

    Solar power is DC, so there is no 'rotational mass' of any sort. Solar is run through inverters to make it AC. Since this is an electronic process, synchronization occurs thousands of times a second.

    Wind power turbines may be AC, but they are variable speed so they also get synced to the grid via electronics. Power is stored on a cycle by cycle basis in banks of supercapacitors. The incoming charge controller and outgoing load controller operate independently of each other.

    Battery storage is best organized as a '3-tier' system: storage at the generator farm, storage at switchgear stations, and storage at end-user-consumers, such as cars and appliances. Farm storage should be focused on leveling 'surges' – huge gusts or temporary lulls, making it possible for the rest of the grid to compensate with a 'bit of play'. Switchgear storage is basically the 'tank farm' of long term battery storage – these should be able to maintain six month reserves. These are designed to even out the longest swings, the variation between winter troughs, summer peaks, fall and spring wind surges, etc. Homes and businesses should design their storage systems to handle two week grid outages, as might happen during ice storms or hurricanes.

    When entirely renewable storage grids settle out, this is most likely how they will be configured.

Totally ridiculous. This guy is delusional, full of misplaced optimism; the storage problem is not close to being solved.

    The obvious solution is already given by how old powerplants uphold stability within seconds. Just build a few wind turbines or panels extra, not to feed the grid, but to feed inertia within some mass in which you tap in whenever shortterm fluctuation needs balance. done.

    Engineers not controlled by greedy owners or dreamers trying to get rich of a new patent, would probably fix it within a heartbeat by using what already works in practice. As for mid/long term energy reserves we already have power plants working with water or other storage substances. A waterpump storage plant in my city is disused and partly dismantled because burning coal or contaminating your disposal sites with radioactive waste is still far too cheap (as we still dont factor in the long term cost and damage in prices, pushing a huge bill to future generations). Just reactivating and modernizing what we already have build would give my city instant access to a huge energy storage supporting a much larger share of solar/wind energy .. its just the corrupt lobby of the fuel burning and nuclear powerplants and the ignorant citizen who are in the way, not some technical impossibility.

    It seems like some of those giant solar towers would solve that problem.

    It's all cool till one of these things catch fire and kill all the birds in a region. Give me nuclear or coal fired any day.
