Observing the renewable energy transition from a European perspective

Hydrogen Economy in the Orkney Islands


The Scottish Orkney islands produce more renewable electricity from tidal and waves than it can consume, which creates some space to experiment a little, with hydrogen. The largest distance on the main island is merely 24 miles, so max. vehicle range is not an issue. Now the inhabitants have a dream of running their cars, ferries and boilers on hydrogen. All of them. With 21,000 inhabitants the project seems to be doable. By 2021, the world’s first hydrogen sea-going ferry should be in operation here. The ambition of the people of Orkney is to be an inspiration for others.

Ecovat – What’s new?

(Dutch language)

When talking about renewable energy, most people have associations with solar panels and wind turbines. The reality in Europe is though that 50% of the fossil energy budget is spent on space heating. Seasonal storage of heat offer perhaps the largest potential to really save on fossil fuel consumption. The Dutch startup Ecovat provides seasonal storage of heat solutions at a scale of a few hundred households. One 1,000 MWh Ecovat is the storage equivalent of 70,000 Tesla Ppowerwall 2. Ecovat estimates the market potential in the Netherlands of 2,000 vessels or more.

Energy Transition Index 2019

The World Economic Forum studied 115 countries to see which ones were the best prepared to achieve the renewable energy transition first. The result was no surprise: Europe is best positioned, just like last year.

The report says despite the diversity of the top performing nations in their primary energy mix, systems and resources, they all share certain characteristics, demonstrating a combination of technical advances and effective policy-making and implementation.

Countries with high ETI scores also performed well on their readiness for energy transition, with Finland topping that list, followed by Denmark, and Austria in third.

Again, these countries have commonalities: stable regulatory frameworks, innovative business environments capable of attracting investment and strong political commitment to energy transition.

Ammonia as the Fuel of the Future

The hydrogen economy may experience a revival, the old problems still exist. Hydrogen is, to put it mildly, not easy to handle. Fortunately there are derivatives from hydrogen as an energy storage medium, that solve some of the hydrogen problems. Ammonia is one of them. A new impetus in that direction comes from the university of Aarhus in Denmark. The progress made entails improved methods of producing N2 and H2 without fossil fuel. Ammonia (NH3) is subsequently produced in the conventional way and is to be burned as a liquid fuel in a fuel cell. Ammonia is to be produced solely with the ingredients electricity, water and air. The projects is concentrating on heavy traffic (ships, trains).

The German company MAN is planning to have an ammonia-fueled marine engine operational by 2022.

Challenges that remain: low flammability and incomplete combustion of ammonia, resulting in undesirable NOx emissions. Ammonia is toxic for humans

Scientists Transmit Electricity Wirelessly Through the Air

Youtube text:

Since the 1960s, space enthusiasts and international space agencies have had one dream: to collect solar power and use it on earth. What seemed utopic more than 40 years ago is about to become reality: the Japanese Aerospace Exploration Agency JAXA especially is hell-bent on harvesting solar energy from space by 2030.

Researchers from the Japan Aerospace Exploration Agency (JAXA) managed to transfer 1.8 kilowatts of power via microwaves to a specific receiver located at a distance of 170 feet (55 meters). You may think that it’s not such an impressive distance, and the delivered energy was only enough to power an electric kettle, but the experiment opens up new prospects for alternative energy research. In particular, similar technology could be utilized for collecting solar energy in space and delivering it to Earth. In fact, this is how the International Space Station is powered – it converts sunlight into electric current with the help of solar cells placed on its solar array wings.

The Japanese Science and Economy and Trade Ministry are currently pushing the project, set to launch in 2030. Just last month they put together the Institute for Unmanned Space Experiment Free Flyer (USEF) consortium consisting of several high-tech giants such as Mitsubishi Electric, NEC, Fujitsu and Sharp. Given that Japan has few energy resources of its own and therefore relies heavily on oil imports, it is no surprise that the country has long been a leader when it comes to solar and other renewable energies.

It seems that after more than a century, someone eventually managed to come close to Nikola Tesla’s breakthrough in transferring wireless electric power. Japanese scientists for the first time succeeded in transmitting electricity wirelessly through the air.

In any case, I strongly believe that the world community will soon realize that alternative sources of energy are the only way for humanity to survive. While definitely different than Tesla’s idea of FREE energy, if the SSPS is finally implemented, we would have a permanent supply of wireless electric power regardless of the time of the day and the weather conditions.
