There is so much discussion about Hydrogen as a source of clean energy because, it is the choice of Nature. Nature has provided us with fossil fuels which are Hydrocarbons, chemically represented by CxHy, Carbon and Hydrogen atoms. In the absence of Hydrogen in a Hydrocarbon, it is nothing but Carbon, which is an inert material. The Hydrocarbon gets its heating value only from the presence Hydrogen atom. The natural gas, now considered as the cleanest form of Hydrocarbon is represented by the chemical formula CH4, containing 25% Hydrogen by weight basis. It represents the largest Carbon to Hydrogen ratio at 1:4.This is the highest in any organic chemicals. In aromatic organic compounds such as Benzene, represented by C6H6, the Hydrogen content is only 7.69%.Even in Sugar which is an organic compound from Nature, represented chemically as C12H22O11 has only 8.27% Hydrogen. But Bioethanol, derived from sugar represented by C2H5OH has almost 13% Hydrogen. Ethyl Alcohol known as ‘Bioethanol’ derived from sugar is blended with Gasoline (Hydrocarbon), for using as a fuel in cars in countries like Brazil. Brazil is the only country that does not depend on imported Gasoline for their cars. The same Bioethanol can also be derived from Corn starch. But the starch should first be converted into sugar before alcohol is derived; that is why it is more expensive to produce Bioethanol from starch than from cane sugar molasses. The climatic conditions of Brazil are more favorable for growing Cane sugar than corn. Brazil is in a more advantageous position than North America, when it comes to Bioethanol. US is one of the largest consumer of Gasoline.US has imported 11.5 million barrels/day of oil in 2010.It has used 138.5 billion gallons of Gasoline (3.30billion barrels) in 2010) according to EIA. (US Energy Information Administration) It is estimated that Brazil’s sugar based Alcohol is 30% cheaper than US’s corn-based Alcohol. Brazil has successfully substituted Gasoline with locally produced alcohol .They also introduced ‘flexible fuel vehicles’ that can use various blends of Alcohol-Gasoline. Most of the Gasoline used in US has 10% Ethanol blend called E10 and E15, representing the percentage of Alcohol content in Gasoline. Brazil is the largest producers of Bioethanol in the world. Both Brazil and US account for 87.8% of Bioethanol production in the world in 2010 and 87.1% in 2011.Brazil is using Bioethanol blends of various proportions such as E20/E25/E100 (anhydrous alcohol) (Ref: Wikipedia). Almost all cars in Brazil use Bioethanol blended Gasoline and even 100% anhydrous Bioethanol are used for cars. Brazil has set an example as a ‘sustainable economy introducing alternative fuel’ to the rest of the world. The ‘bagasse’ from cane sugar is also used as a fuel as well in the production of ‘Biogas’, which helps Brazil to meet sustainability on renewable energy and greenhouse gas mitigation. The above example is a clear demonstration of sustainability because natural organic material such as sugar is the basic building block by which we can build our Sustainable clean energy of the future. The same Bioethnanol can easily be reformed for the production of Hydrogen gas to generate power and run Fuel cell cars. Many companies are trying to use chemicals such as metal Hydrides as a source of Hydrogen. For example, one company successfully demonstrated using Sodium Borohydride for Hydrogen production. Many companies are trying to find alternative sources of Hydrogen generation from water, including Photo-electrolysis using direct solar light and special photo catalyst materials. We know Nature produces sugar by using sun’s light, water and carbon dioxide from air by photosynthetic process. Can man duplicate this natural process and generate Hydrogen at the fraction of the cost by simply using water and sun’s light? The race is already on and only time can tell whether our pursuit for cheap and clean Hydrogen can become a commercial reality or just stay as an elusive dream.

- Zero-emission baseload power using only sun and seawater.It is estimated about 2000 billion tons of anthropogenic CO2 has been emitted and absorbed by both air and sea since the industrial revolution. Therefore, it is clear there is no need to source anymore Carbon from coal, oil, and gas. This basic fact is of paramount importance in solving the emission problem moving forward […]
- Can CCS and CCUS lead us to achieve net zero emission by 2050?CCS (carbon capture and sequestration) and CCUS (Carbon capture, utilization, and storage) technologies are essentially “after thought” to fix the CO2 emission by 2050. It also indirectly encourages continuity of fossil fuel usage for a foreseeable future to help those industries who have invested billions of dollars in creating their infrastructures including “fracking”. Fracking generates […]
- Renewable synthetic methane gas (RSMG) and Ramana Power Cycle (RPC) for Zero emission base load power.RSMG is an abbreviation for ‘Renewable synthetic methane gas’ and it is a new form of a Carbon negative synthetic fuel to substitute natural gas. It is synthesized using CO2 extracted from the sea or from power plant using Oxy combustion CO2 power cycle at the site such as CES, Graz cycle or Allam cycle […]
- Ramana Power Cycle (RPC)Carbon emission has become a serious issue as the globe warms changing the climate. However such emissions can be turned back into fuel using renewable energy sources and achieve Zero Carbon emission using readily available technologies.
- Can Hydrogen substitute Carbon and avoid catastrophic climate changeThe answer is most likely NO for the following reasons. It has been established that man-made GHG emissions mainly by CO2 is causing the globe to warm by a phenomenon known as “Greenhouse gas effect” triggering change in climate. Therefore, many are suggesting Hydrogen as an alternative clean fuel to reduce or eliminate CO2 emission. […]
- New realities of decarbonizing fossil economy and the science of climate changeGlobal warming and climate change are the topics of the day and doomsday predictions are abounding. In a divided world of differing ideologies and dogmas, emotions play a major role and all conclusions are drawn out of such emotions. Emotional intelligence is the key and in-depth analysis will clear the clouds of doubts and disbeliefs […]
- Carbon Recycling Technology (CRT) is a potential solution for Zero Carbon Emission.This article describes how to generate base load power with Zero Carbon emission. The technology is available for immediate commercialization.
- The real solution for Carbon problem:When mother nature buried Carbon under the ground by way of fossil, we human beings mined them at enormous cost and added further value by combustion with air converting it into CO2 (carbon dioxide). In fact, we human beings added enormous value to carbon that remained buried (with zero value) for millennia. We were interested […]
- Renewable Hydrogen, an emerging alternative to fossil fuelFossil fuels such as coal, oil and gas have helped transformed our power and transport industries for decades till now. But recent geo-political situations, depleting fossil sources and Carbon pollution, global warming and climate change have raised serious questions about the future of fossil fuels. However, countries who have massively invested in fossil fuel infrastructure […]
