According to the IEA Electricity Market Report of Feb 2023, by 2025 world electricity demand will increase to 2,500 TWh above 2022 levels, meaning that over the next three years the annual increase in electricity consumption will be approximately equivalent to that of Germany and the United
Kingdom combined. A sobering thought!
Renewables and nuclear energy will dominate the growth of global electricity supply over this period, together meeting on average more than 90% of the additional demand, with their share of the power
generation mix rising from the 2022 level of 29% to 35% in 2025. China is set to meet more than 45% of renewables generation, and the EU 15%.
The difficulty is that, while being an excellent medium for renewable energy storage, hydrogen itself is
tricky to store.
This is because it has a low volumetric energy density compared with other gases — such as natural
gas — meaning it takes up much more space. Also, hydrogen has a boiling point close to absolute zero
and so in its liquid form requires cryogenic storage. Furthermore, under certain conditions, it can
cause cracks in metals, particularly in iron and high strength steel. This is known as ‘hydrogen embrittlement’. However it’s a potential issue that can be resolved.

PERFORMANCE ANALYSIS OF HYDROGEN FUELED INTERNAL COMBUSTION ENGINEijsrd.com
In the history of internal combustion engine development, hydrogen has been considered at several phases as a substitute of hydrocarbon-based fuels. Starting from the 70’s, there have been several attempts to convert engines for hydrogen operation. Together with the development in gas injector technology it has become possible to control precisely the injection of hydrogen for safe operation. Here we are using stainless steel plate as electrode in the electrolytic cell, the electrolyte being water and NACL salt. The electrolytic cell we used is a 12V battery case made of plastic. The cross sectional layers are cut such that the stainless steel plate fix in the battery case. The plates are separated by very small distance and the plates are given parallel holes for electron flow to be uniform. The power source to the kit is provided by a 12V and 9Ams battery. We used a transparent tube to supply the hydrogen produced in the kit to the air hose tube of our motor cycle. In order to keep the battery charged we used two 6 Amp diode to power the battery while running. There is a separate switch to power the kit and to protect the battery from getting drained. The stainless steel plates are of 50cm length, 25cm height, 2 millimeter thickness. The battery case can hold up to 5 liters of electrolyte. The use of hydrogen with petrol to power the vehicle has resulted in increase in vehicle mileage, accelerating speed with most important task of reduction in exhaust emission.

Micro RNA genes and their likely influence in rice (Oryza sativa L.) dynamic ...Open Access Research Paper
Micro RNAs (miRNAs) are small non-coding RNAs molecules having approximately 18-25 nucleotides, they are present in both plants and animals genomes. MiRNAs have diverse spatial expression patterns and regulate various developmental metabolisms, stress responses and other physiological processes. The dynamic gene expression playing major roles in phenotypic differences in organisms are believed to be controlled by miRNAs. Mutations in regions of regulatory factors, such as miRNA genes or transcription factors (TF) necessitated by dynamic environmental factors or pathogen infections, have tremendous effects on structure and expression of genes. The resultant novel gene products presents potential explanations for constant evolving desirable traits that have long been bred using conventional means, biotechnology or genetic engineering. Rice grain quality, yield, disease tolerance, climate-resilience and palatability properties are not exceptional to miRN Asmutations effects. There are new insights courtesy of high-throughput sequencing and improved proteomic techniques that organisms’ complexity and adaptations are highly contributed by miRNAs containing regulatory networks. This article aims to expound on how rice miRNAs could be driving evolution of traits and highlight the latest miRNA research progress.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.
2. power generated on windy or sunny days into hydrogen, the gas can store renewable energy that can
then be deployed at times of peak demand as a clean fuel source for power generation.
Second, hydrogen can replace fossil fuels to decarbonise sectors where electrification alone isn’t
adequate, such as domestic heating, industry, shipping and aviation. As an energy source it is very
scalable.
The difficulty is that, while being an excellent medium for renewable energy storage, hydrogen itself is
tricky to store.
This is because it has a low volumetric energy density compared with other gases — such as natural
gas — meaning it takes up much more space. Also, hydrogen has a boiling point close to absolute zero
and so in its liquid form requires cryogenic storage. Furthermore, under certain conditions, it can
cause cracks in metals, particularly in iron and high strength steel. This is known as ‘hydrogen
embrittlement’. However it’s a potential issue that can be resolved.
Here are four hydrogen storage solutions that could help address these challenges.
1. Liquefied hydrogen
As well as being stored in its gaseous state, hydrogen can also be stored as a liquid. In fact the space
industry has been using liquefied hydrogen to fuel rockets for many years.
But liquid hydrogen storage is technically complex and thus quite costly. It has to be cooled to -253°C
and stored in insulated tanks to maintain the low temperature and minimise evaporation. This requires
complex and expensive plant which has limited the use of liquefied hydrogen.
The semiconductor chip industry is also a major user of liquefied hydrogen. However, with the
proliferation of renewable hydrogen supply and demand, greater economies of scale will make
liquefaction a more viable storage and transport option in the future.
2. Compressed hydrogen storage
Like any gas, hydrogen can also be compressed and stored in tanks, and then used as needed. However
its volume is much larger than that of other hydrocarbons relative to their weight — nearly four times
greater than natural gas. So for practical handling purposes, hydrogen needs to be compressed. For
example, fuel-cell powered cars run on compressed hydrogen contained in highly pressurised
containers.
If an application requires hydrogen volume to be reduced further than attainable by compression, it
can be liquefied. The two techniques — compression and liquefaction — can also be combined.
Hydrogen’s low energy density, high volume, and need for cryogenic storage are some of the biggest
barriers to its adoption. This is especially true for use in transportation, where a balance must be
struck between passenger space and range.
3. Geological hydrogen storage
The storage of hydrogen underground, both onshore and sub-sea in caverns, salt domes, depleted oil
and gas fields, and aquifers (porous rock or sediment saturated with groundwater) is fast-becoming a
serious contender for hydrogen storage at scale. In fact gas storage in salt caverns is a long-established
method, making the technology easy to adapt.
