Power One AB consider hydrogen in Burundi

 

Power One´s concept combines wind, water and sun as sources of energy production. This reduces the need for expensive storage. Power One plans to use electrolyte storage, but will also set aside part of the solar park to operate a hydrogen gas production plant, which can be used, among other things, to operate boats. Since Tanganyika Lake is still clean and crystal clear, the electric propulsion of boats is an obvious complement for preserving it undisturbed. At present, there are a number of vessels operating on oil, which are used but have not so far done too much damage. Hydrogen has the advantage of being considerably cheaper as a fuel then fossil fuel, and is therefore an irresistible substitute from all points of view.

 

Hydrogen can be used for electrically driven transport on both land and water. During manufacture, water is divided into oxygen and hydrogen. The hydrogen gas is collected in tubes and then transformed into electricity via a so-called power cell. With a hydrogen tube, a power cell and an electric motor, many electric vehicles are operated today, ranging from mopeds, cars and trucks to boats. It is a durable and well-proven technology whose only residual product is oxygen and water. Oxygen is used in everything from healthcare to welding and is an import commodity in Burundi. Both oxygen and hydrogen can therefore be sold with good profits for Power One.

 

 

Hydrogen is a well-known and reliable energy storage system that has been used in industry for almost a century. The technique is simple: DC voltage produced during the day from solar panels is used in an electrolyser to separate water (H2O) into hydrogen (H2) and oxygen (O). The non-polluting oxygen is released and the hydrogen is stored under pressure into simple and durable containers. At night, when the sun is on the other side, hydrogen is led into a power cell that melts hydrogen with oxygen from the air back into water. Through this process, energy from daylight is restored back to electricity and used for night consumption.

 

If the solar park produces more energy under daylight than is consumed during the day and at night, the excess can be used to produce hydrogen for other applications, e.g. transport on the lake. In this case, hydrogen is transferred to gas tubes in the boats and then converted back to electricity via a fuel cell. This then provides electricity to the electric motor in the boat.

 

This is a very simple, well tested and durable system. With a simple pressure tank, a fuel cell and an electric motor, hydrogen can be used to operate all transport, including air, and today most of the major car manufacturers have developed hydrogen cars. The conversion of the region's boats to hydrogen operation is quite simple and plans are underway to start a rebuilding yard in Kabonga fishing port for this.

 

- By introducing an environmentally smart and emission-free boat traffic on Lake Tanganyika, Burundi will also market itself in quality tourism and offer an ecological alternative to other countries, says Janvier Nsengiumva, Commercial chief Port of Bujumbura.

Power One invests in smart hydro

Hydropower is a renewable source of electricity, but in traditional form it not only destroys entire valleys for its reservoirs, it also destroys natural biodiversity. But that is how it used to be. Today it is also an ecologically sustainable source. With today's so-called smart hydroelectric plants, no valleys are submerged. Biodiversity is not destroyed by these either. Power One has therefore decided to utilize the hydropower in the small river that flows through Kabonga. It is a small river, but with a constant flow even during the dry season, and is well suited for smart hydropower.

What is the difference between traditional and smart hydropower?

Last century was the century of large scale. At that time, almost all hydropower was built with dams and turbines. The dams were used to even out production during the year. However, these dams have placed large areas of forest land under water, while at the same time they have become obstacles to fish migrations. Not only the forests in the valley above the dam but also the biodiversity of the river were affected. Fish cannot get up or down alive through a turbine, and as many species of fish multiply in special places, to where they must move, entire species have also disappeared from river systems.

The smart hydropower does not use dams. By removing these, the disadvantages of hydropower are avoided, but at the same time, of course, its purpose disappears, to level out the seasonal changes of hydroelectric power. When using smart hydropower instead this has to be compensated by combining power sources that have different seasonal cycles, like wind and solar. In this way, both the costly and environmentally damaging dam plant is avoided. Instead, freedom is gained from using small and inexpensive systems that are also scalable. Instead of a single large plant, the fall height can be utilized in several places. Today thereare plenty of different varieties of smart hydro adapted to different conditions. Power One in Kabonga will therefore use different smart hydro in different parts of the river.An example of a smart hydro that does not affect biodiversity is the Dutch Turbulent. A Turbulent smart hydro costs between $ 80,000 to $ 300,000, but it generates approximately the same revenue in three year under favorable conditions. The water flow in the small river in Kabonga is at least 1 m2 per second, year-round. This is suitable for the smaller turbulent power plants, which are located at about 55 kW. To calculate the power economically, you multiply the installed power by 7500 and by the price per kilowatt. For a 55kW power plant in Kabonga, the calculation is 55 kW x 7,500 x 0.24 USD, which gives an annual revenue of $ 100,000 for an investment of $ 300,000. The fall height of the small river in Kabonga is just over two hundred meters, and since each power plant does not require more than a maximum height of 4 meters, the river can accommodate a large number of these, without negative impact on the river's fish and fauna. However, there are more models of smart hydro that are suitable for different conditions.

 

A design of smart hydropower requires many factors, including flow, altitude, geology and biology. Power One's Peter Rinaldo gives in the following filmed reportage a picture of how the initial design work in Power One goes.

Power One will invest in smart wind

Wind power is a renewable source of electricity. Traditionally, it has required steady and steady wind to be effective. The old "propeller spins" with horizontal shaft cannot withstand turbulent winds, although it can contain as much energy. The so-called vertical wind turbines have not previously reached the same efficiency as the propeller-driven, but have now been updated with more shafts and thus a whole new ability to take advantage of turbulent winds. They are also effective on a smaller scale and Power One has now decided to use these instead of the traditional ones.

Traditional propeller-type windmills use the “horizontal axis x propeller type” method, but the horizontal axis is difficult to respond to changes in wind direction, and the propeller type has a risk of runaway velocity due to strong winds. A horizontal axis propeller type windmill can generate power with high efficiency when the wind direction and wind speed are bothstable, but it is difficult to cope with sudden changes in wind speed and direction. The wind direction of the tropics is not stable, and under such circumstances, the vertical axis Magnus wind turbine can achieve stable operation and achieve a higher capacity utilization rate.

The "vertical axis Magnus type" system is compatible with wind in all directions because of the vertical axis, and by using the Magnus type, the rotational speed of the wind turbine can be kept constant according to the wind speed by controlling the rotation of the cylindrical blades. can. By controlling the rotation speed of the windmill, stable power generation is possible without runaway even in sudden strong winds. The wind environment in the tropics is very harsh for windmills that are subject to drastic changes in wind direction and speed and among them, the vertical axis Magnus wind turbine can generate power stably, and it can be expected to dramatically improve the operating rate of the wind turbine. In addition, by using a cylindrical blade instead of a propeller, the manufacturing cost can be greatly reduced, so it is possible to supply inexpensive power using renewable energy. 

Tanganyika is a fantastic lake. It is huge not only to the surface but also to the depth. It is also pure and undisturbed with one of the world's largest biodiversity. Because of its surface, the winds get a smoother flow and do not become as turbulent. Therefore, the shores of the lake are suitable for the traditional propeller-driven wind turbines. However, these are both costly and difficult to maintain. They also have a great aesthetic influence. Since the modern vertical wind turbines do not require proximity to the lake's steady flow, they can be placed a little anywhere, preferably up in the mountains.

Power One will therefore invest in a larger number of these vertical small power plants up in the mountains instead of a large propeller-driven power plant at the lake.

China passes law allowing regions to set resource taxes

SHANGHAI/SINGAPORE - Chinese legislators approved a new law on Monday that will give local governments authority to tax as many as 164 different resources, including fossil fuels, minerals and eventually water, the Ministry of Finance said on Monday. The National People’s Congress, China’s parliament, approved the new resource tax law on Monday and it will go into effect in September next year, the ministry said in a briefing.
Officials insisted it will not raise the overall tax burden on local firms.
