Vattenfall Orders 1 GW Wind Park from Siemens-gamesh

The largest offshore wind order of 2017: the three wind farms, Kriegers Flak in the Baltic Sea and Vesterhav Syd and Nord in the North Sea, have a total investment value of close to EUR 1.7 billion (SEK 16.5 billion).

Largest European Battery Plant to be Built in Sweden

[source]

The Swiss engineering company ABB has teamed up with Northvolt of Sweden to build the largest lithium-ion battery plant in Europe in order to meet growing demand from the automotive industry. The plant should rival the Gigafactory in the Nevada desert. Target: 32 GWh in 2023. 80-100 million euro will be necessary to get production started.

Leif Holmnid & Ultra Dense Fusion

Fusion energy may soon be used in small-scale power stations. This means producing environmentally friendly heating and electricity at a low cost from fuel found in water. Both heating generators and generators for electricity could be developed within a few years, according to research that has primarily been conducted at the University of Gothenburg… A collaboration between researchers at the University of Gothenburg and the University of Iceland has been to study a new type of nuclear fusion process. This produces almost no neutrons but instead fast, heavy electrons (muons), since it is based on nuclear reactions in ultra-dense heavy hydrogen (deuterium)… The new fusion process can take place in relatively small laser-fired fusion reactors fuelled by heavy hydrogen (deuterium). It has already been shown to produce more energy than that needed to start it… Research shows that far smaller and simpler fusion reactors can be built. The next step is to create a generator that produces instant electrical energy.

Under Water Kites

Youtube text:

Minesto develops a new concept for tidal power plants called Deep Green. Deep Green is based on a fundamentally new principle for electricity generation from tidal currents. The power plant is applicable in areas where no other known technology can operate cost effectively due to its unique ability to operate in low velocities. Minesto expands the total marine energy potential and offers a step change in cost for tidal energy.

The principle of the technology can be explained as a two stage process.

The first stage increases the relative flow speed entering a turbine. When the tide hits the wing it creates a lift force, since the kite is mounted to the ocean bed with a tether and is controlled by a rudder, the kite can be taken in the desired trajectory, here in an eight formed path. The method increases the flow velocity into the turbine by 10 times, compared to the actual stream velocity.

The second stage uses a generator to convert kinetic energy into electrical power.

The net result is increased power from a smaller package. The planned normal full size weighs only 7 tons excluding anchoring which gives an energetic payback time of 3 weeks, compared to 8 months for onshore wind.

The test confirms power production of the plant at Marin in Holland.

Potential: 800 kW per kite
First project: Anglesey, Wales/UK (Holyhead Deep)
Project size: eventually 80 MW
Span width kite: 12 meter
Argument pro under water kite: one needs 15 times less material per generated kWh as compared to wind turbines
