A simple Example of Energy Efficiency Concept

Energy efficiency

Energy efficiency is a very broad term referring to the many different ways we can get the same amount of work (light, heat, motion, etc.) done with less energy. It covers efficient cars on the roads, efficient ships in the waters, improved industrial practices, better building insulation and a host of other technologies. Since saving energy and saving money often amount to the same thing, energy efficiency is highly profitable and great contributor for the climate change issue. Energy efficiency often has multiple positive effects.

Algae to crude oil – Innovation of a Green Energy Source

The PNNL (Pacific Northwest National Laboratory) Engineers have created a continuous chemical process that produces useful crude oil minutes after they pour in harvested algae — a verdant green paste with the consistency of pea soup.

In the PNNL process, a slurry of wet algae is pumped into the front end of a chemical reactor. Once the system is up and running, out comes crude oil in less than an hour, along with water and a by-product stream of material containing phosphorus that can be recycled to grow more algae.

On the way of innovation- the Most Energy Efficient Car!

123
Impressive news from the new Prototype CNG category late yesterday afternoon: team Microjoule-La Joliverie pulled off a 2,521km/litre equivalent first attempt (imagine driving from Rotterdam to Palermo on one litre). New category, new benchmark.

The first UrbanConcept challenge started this morning. First on track was Louis Delage School from France with their gasoline car, pulling off 476km/litre equivalent to lead their category and set a new record. French Team IUT GMP Valenciennes from France have set a record of 1,323km/l in the Prototype diesel category.

Audi E-Diesel- Fuel of The Future

audi-fuel
After a commissioning phase of just four months, the research facility in Dresden started producing its first batches of high‑quality diesel fuel a few days ago.
The Dresden energy technology corporation sunfire is Audi’s project partner and the plant operator. It operates according to the power‑to‑liquid (PtL) principle and uses green power to produce a liquid fuel. The only raw materials needed are water and carbon dioxide. The CO2 used is currently supplied by a biogas facility. In addition, initially a portion of the CO2 needed is extracted from the ambient air by means of direct air capturing, a technology of Audi’s Zurich‑based partner Climeworks.

Fossil Fuels and Renewable Energy for Ships

aquarius_eco_ship_2b

Fossil fuels are the major energy sources in today’s world but still when over consumption takes place lead to disastrous effects such as air pollution and climate change. Burning of fossil fuels produces carbon dioxide, carbon monoxide, nitrogen monoxide, nitrogen dioxide, sulphur dioxide etc. that have severe bad effects on the habitats as well as affect human health.

Electric Mobility: Hybrid Electric Ship

By Siemens.

1411241819405
Today, the frequency converter, by way of the electric motor, controls the propeller rotation speed directly. As a result, the propeller can turn much more slowly. In order to maintain a vessel’s position at sea or to move at very slow speeds, the amount of propulsion needed is sometimes so minimal that it need not be more than the power to adjust the pitch of the propeller blades.

Flettner Rotors- The Wind Turbines as Ship’s Propulsion

By Enercon GmbH.

arti_e-ship
The E Ship 1, with four tall pillars rising vertically from the ship, two forward and two aft, is using Flettner rotors as ship’s propulsion. The Flitner rotors technology was first developed in the 1920s by German engineer Anton Flettner. They are in essence, motor powered sails, 27 meters tall and 4 meters in diameter. The spinning vertical rotors develop aerodynamic lift using the Magnus effect. As the wind blows across the spinning rotors, they develop lift similar that of an airfoil shape of a conventional sail. Unlike masts and sails, however, the vertical Flettner rotor does not interfere with cargo operations. The Flettner rotors are expected to save 30-40% in fuel costs at 16 knots.

Wind is the cheapest, most powerful, and greenest source of energy on the high seas.

With SkySails, modern cargo ships can use the wind as a source of power – not only to lower fuel costs, but significantly reduce emission levels as well.

The worldwide patented SkySails propulsion system consists of three main components:
i. A towing kite with rope,
ii. A launch and recovery system, and
iii. A control system for automated operation.

A Combined Wind & Solar Power Solution for Ships

By Greg Atkinson, Eco Marine Power.

A Combined Wind & Solar Power Solution for Ships

From small powered pleasure craft and ferries to large super-tankers, the limitless energy of the wind and sun can be used in order to help power ships thereby reducing fuel consumption, the emission of greenhouse gases (GHGs) and noxious exhaust emissions.

Unlike land based renewable energy solutions such as solar or wind farms, the area or space available on ships for installing wind & solar power systems is quite limited. Taking this into account it would appear advantageous to develop a system that can use both wind and solar power as energy sources plus harness this energy via the same system.

Impressed Current Cathodic Protection (ICCP) System

HOW DOES AN ICCP SYSTEM WORK?

– Using an arrangement of hull mounted anodes and reference cells connected to a control panel(s), the system produces a more powerful external current to suppress the natural electro-chemical activity on the wetted surface of the hull.

– This eliminates the formation of aggressive corrosion cells on the surface of plates and avoids the problems which can exist where dissimilar metals are introduced through welding or brought into proximity by other components such as propellers.

Accelerating the development of innovative technologies to reduce CO2 emissions from vessels is essential to both cope with rising fuel costs and to improve the world environment. This can be achieved through the development of various CO2 abatement technologies, such as low-friction coatings, hybrid contra-rotating propulsion systems, solar power, and liquefied natural gas-fueled plants. We focus on the proprietary Mitsubishi Air-Lubrication System (MALS), which reduces frictional resistance between the vessel hull and seawater using air bubbles along the bottom of the vessel.
