Due to the growing world population and the thereby increasing energy consumption and continous rising prices for all conventional energies, known to us, as e.g. oil, coal, peat, firewood, natural gas (Methangas CH4), so-called fossil energies by decayed biomass, the people search for alternative energies. Besides the rising prices of the aforesaid energy carriers, these energy carriers (solid and liquid, like oil, coal, peat and wood and other biomasses) release carbon in the combustion (CO2) which strongly pollute the environment, damage the peoples‘ health, and have a negative impact to the climate.

Natural gas in contrast to liquid and solid hydrocarbons, has an about 40% lower carbon-fraction and can therefore, be called a low-carbon energy and gas. The use of natural gas CH4 is thus wanted and needed for active climate protection. Optional, if carbon is entirely extracted, hydrogen gas solely remains. It is absolutely CO2-free and universally usuable. Such alternative energies are also called renewable or sustainable energies. Alternative manufacturing techniques derive either by electricity, or gas/biogas/methan gas, CH4, or hydrogen gas H2. By gasification of all kinds of biomass so-called biogas, Methangas CH4 is produced and the same as natural gas, however, and be manufactured by fermentation and gasification technologies of fresh biomasses. Either biomass wastes or renewable raw materials like fast-growing trees or plants, can be used as natural resources for the fermentation or gasification. The advantage of gas is its inexpensive production, storage, transportability, and combustion. Furthermore, it contains 40% less carbon, which means an active climate protection and health prevention. Optionally, gas can also be electrified in gas engines and gas fuel cells. We thus talk about a universal energy form, or carrier and storage,  which can particularly be used in rural areas, where there are no power lines. In so far, the use of natural gases is the most appropriate energy form for developing countries in Asia, Africa, or the Americas,  because no power lines over thousands kilometers and likewise, no electricity storage like batteries, are needed. Get a meaningful occupation and natural gas and biogas as an alternative, sustainable energy form. Renewable Energy is the energy solution for Asia, Africa and Americas. The most renewable and sustainable is Hydrogengas and in combination with Fuel Cells use it for Home and Mobility and even for Urban Transports with Cars, Buses, Scooters and Boats. Let me know your question and ask me for more Detaisl.
