Tesla Overtakes Volkswagen in Company Value

Tesla has displaced Volkswagen as the world’s second most valuable carmaker, after a dramatic rise in share price pushed its market value to more than $100bn (£76.1bn). The milestone sets the stage for chief Elon Musk to collect billions in pay tied to hitting that target. Tesla’s share price has more than doubled since October, when the firm reported a rare quarterly profit.

First Monopiles Installed at Borssele Offshore Wind Project

The Borssele I-V 1.5GW offshore wind project is currently the largest in the world (but not for long). This is Ørsted’s first project in the Dutch part of the North Sea. The first and largest monopile of a weight of 1,188 ton and a length of 76 meter has been rammed into the seabed. Borssele I-II is expected to be operational later this year and will produce sufficient electricity for 1 out of 8 million Dutch households. The 94 monopiles in total will have been installed by April, after which the towers and Siemens-Gamesa turbines can be installed in a couple of months more.

Metal Fuel Gets a Subsidy Boost

A club a students of the Technical University of Eindhoven in the Netherlands, called TeamSolid, is working on a new energy storage system, based on a fuel cycle: {iron powder –> burning, producing heat for a Stirling engine –> producing iron rust powder –> reduction to iron powder, which costs energy}:

TeamSolid managed to get a 20 kW system to work and now are provided with the opportunity to scale up to 100 kW, thanks to 1 million subsidy from the province of North-Brabant. Interested corporations foot the remaining 1.8 million euro. The 100 kW installation will bu utilized by the Bavaria-brewery. In order to brew beer, Bavaria needs steam and electricity, that are currently both provided by burning natural gas. The goal is to burn iron powder rather than natural gas in order to avoid CO2-emissions. Many third interested companies are watching from the sideline to see if something could be in it for them.

New Aeolus Video

This latest video shows the Aeolus with a new, larger crane, enabling the ship to handle the largest wind turbines to date.

The Aeolus is probably the most advanced offshore wind-turbine installation ship in the world today. German-built, Dutch owned, this ship is able to install a monopile for the latest 10-12 MW wind turbines within 24 hours. If we would add two days for the installation of the tower, nacelle and blades and assume that a simple, much cheaper barge would deliver all these parts at sea, eliminating the need for the expensive Aeolus to fetch these part from the port itself, we arrive at a hypothetical installation capacity of 100 MW per month or 1.2 GW per year. The Netherlands consumes on average 13 GW electricity 24/7/365. That is 11 years installation time. However, even these large turbines have a capacity factor of 60%, so 13 GW real installation (ignoring storage issues), with 6 MW per 10 MW nameplate turbine or 60 MW/month of 720 MW/year, would require 18 years installation time.

Think about it, a single ship is (in theory) able to replace the entire fossil fuel-based power production capacity of a country like the Netherlands, with a population of 17 million, that has the highest electricity consumption per capita in the entire EU, in 18 years time. As a rule of thumb, multiply this with a factor of 2 in order to create a truly renewable energy base, powering everything, including transport and space heating, with heat pumps.

One ship, the Netherlands, 36 years.

Europe has many of the jackup ships.

Do Wind-turbines Kill Birds?

People who oppose wind farms often claim wind turbine blades kill large numbers of birds, often referring to them as “bird choppers”. And claims of dangers to iconic or rare birds, especially raptors, have attracted a lot of attention… Wind turbine blades do indeed kill birds and bats, but their contribution to total bird deaths is extremely low, as these three studies show. A 2009 study using US and European data on bird deaths estimated the number of birds killed per unit of power generated by wind, fossil fuel and nuclear power systems. It concluded, “Wind farms and nuclear power stations are responsible each for between 0.3 and 0.4 fatalities per gigawatt-hour (GWh) of electricity while fossil-fuelled power stations are responsible for about 5.2 fatalities per GWh.“. That’s nearly 15 times more. From this, the author estimated that wind farms killed approximately seven thousand birds in the United States in 2006 but nuclear plants killed about 327,000 and fossil-fuelled power plants 14.5 million. In other words, for every one bird killed by a wind turbine, nuclear and fossil fuel powered plants killed 2,118 birds.

Seabirds are better at avoiding wind turbines than previously thought. Wind farms are far less harmful to birds that first thought, the biggest ever study has shown, because seabirds actively change their flight path to avoid them. Researchers used radar and video to monitor seabirds flying near the Vattenfall’s Thanet offshore wind farm in the English Channel over a two year period. They found that birds were present near the turbines in just two per cent of the 600,000 videos shot during the period, and they recorded just six collisions – an average of one every four months.

Many migrating birds have learned to avoid potentially deadly wind turbines, but this behaviour equals a loss of habitat for the animals, researcher Ana Teresa Marques and others write in the Journal of Animal Ecology…Environmental NGO Nabu estimates about 100,000 birds in the country could be killed by rotor blades each year. To put this figure into perspective: Environmental organisation Friends of the Earth Germany (BUND) says that about 18 million birds in Germany die every year by crashing into windows.

Bosch Announces Complete Autonomous Driving Sensor Package

Lidar does with light what radar does with radio waves. It sends out a beam of light and tracks the photons that bounce back to paint a digital picture of what lies ahead. In theory, it should be the ultimate tool for creating self-driving systems, but it has several drawbacks… Only the parallel deployment of three sensor principles — cameras, radar, and Lidar — can insure that automated driving will offer maximum safety, the company says. “By filling the sensor gap, Bosch is making automated driving a viable possibility,” Bosch board member Harald Kroeger says.

Bye-bye Walkman – Sony Announces Electric Car

Sony is good at keeping secrets and at this year’s CES auto show in Las Vegas, out of the blue, presented an electric car, the VISION-S. The news is very fresh and raises many questions, like will this car go in production and if so, by who? Austrian-Canadian Magna-Steyr, the auto supplier that had a large input? As you could have expect from Sony, the car is stuffed with electronics. The car has two electro-motors, delivering a performance overkill of 272 hp, 100 kmh in 4.8 seconds and a top speed 240 kmh. Fast-green if you will. The range is not communicated by Sony. Apart from Magna-Steyr, other companies on board are Nvidia, Bosch, ZF en Qualcomm.
