Dutch Grid Can’t Take More Solar Power

Ameland, 6 MW

The Netherlands has 3.7 GW nameplate solar power, but the grid in its present shape can’t absorb much more new power and network operators refuse to take solar power from larger parties, like companies or private associations. Private households are still welcome. The problem is the largest in the North of the country, where land prices are relatively lower and much private money is available for new solar parks. It could take years to install new cable capacity.

Perhaps the parties that are shunned by the grid should contemplate producing hydrogen off-grid:

The Scale of the Global Energy Transition

[source] An area in the Sahara with the size of Bulgaria, covered with solar panels and all the world’s present day energy needs would be covered.

The Sahara is associated with strong solar irradiation. How much Sahara surface area would be required to power the entire world with pv-solar? Mehran Moalem, PhD, UC Berkeley, Professor, expert on Nuclear Materials and Nuclear Fuel Cycle, did the calculation.

How much energy is the world consuming anyway?

The total world energy usage (coal+oil+hydroelectric+nuclear+renewable) in 2015 was 13,000 Million Ton Oil Equivalent (13,000 MTOE) – see World Energy Consumption & Stats. This translates to 17.3 TW continuous power.

OK, so how much of the Sahara would be required to generate these 17.3 TW? Surprisingly little:

Now, if we cover an area of the Earth 335 kilometers by 335 kilometers with solar panels, even with moderate efficiencies achievable easily today, it will provide more than 17,4 TW power. This area is 43,000 square miles.

For Europeans, that’s 111,370 km2 or relatively small European countries like Bulgaria, Iceland or Greece. For Americans, think Tennessee or Virginia.

PV-Solar Global Installed Base

Note that the European installed base grew from 45 GW in 2010 towards 120 GW in 2017. That’s 85 GW in 7 years. Linear extrapolation to 2030 would imply an extra 134 GW. In reality it could be (much) more as the price of solar panels is expected to further reduce significantly, think $100/m2 soon. Let’s say 300 GW nameplate in total in 2030, which would be equivalent to 30 GW average power 24/7/365 (see explanation of “nameplate power” in the previous post). From this it is obvious that wind power will be dominant in Europe for years to come.

LightYear Solar One Goes in Production

Solar Team Eindhoven in the Netherlands made good on its promise to bring the world’s first solar car into production. Born from the Australian Solar Challenge, a race for solar cars through the Australian desert, students/engineers from the Technical University of Eindhoven helped maturing the technology to the production stage, realized earlier this month in Helmond, the Netherlands. Initial small volume price tag: 119,000 euro.

For the average Dutch daily range of 34 km and weather conditions, most of the year the car doesn’t need charging from the grid.

SolaRoad Followup Project

YouTube: Sten de Wits, co-founder and commercial director of SolaRoad, spoke to Global Footprint Network during the Global Climate Action Summit in San Francisco, September 13, 2018. He had kindly accepted our invitation to our affiliated event One Planet Progress VIP Breakfast. The event was organized in partnership with, and hosted by, the Dutch Consulate.

The SolaRoad world’s first solar bicycle path in Krommenie in the Netherlands, turns out to be a success and new a, more ambitious project is initiated in Haarlemmermeer. This time heavy traffic will test the solar panels, baked into the prefab concrete slabs.

Again the rationale for the project: Holland is a very densely populated country and soil is expensive and scarce. Where in, say, Mongolia there is ample space to setup a solar panel field, in Holland it makes economically sense for a dual use of road and energy generation function.

Printing Solar Cells

Solliance from Eindhoven, The Netherlands, wants to mover away from standard solar panels towards thin film solar and apply those to surfaces like cars, windows, curved building surfaces or even glasshouses:

They are close to printing cheap roles of hundreds of meters of solar thin film cells, with a conversion efficiency of 12.2-13.5 % on the basis of perovskites.

New Utility Solar Price Record

Speed racing

Nuna Solar Team TU Delft: 3021 km, 14:10:41, average speed 81.2 km/h

Cruising

Solar Team TU Eindhoven: average speed 69 km/h, 6 charges, 10197 person-km, 45.7 kWh external energy, average passengers: 3.4, energy efficiency (person-km/kWh) 223.2

Note that the external energy was necessary due to the long distance of 3021 km in merely 6 days. If the available time would have been 12 days, no extra electricity would have been required. In other words, the daily range without external (grid) charging (but “24h” solar charging) under Australian conditions in October would be ca. 250 km with 5 persons.

Eindhoven btw drove with 5 persons until a major technical malfunction occurred, after which no risks were taken and a single driver-passenger completed the race alone, which pressed down the passenger average. If you offset these 250 km with a daily average distance of merely 37 km in an industrialized country like Holland, you can verify that an energy-autonomous car is not a pipe-dream at all.
