Zeo water heater with zero emissions - Climate CoLab. Pitch A water heater that uses zeolites to store solar energy and later uses the same to heat up water. Description Summary My concept proposes to use zeolites to store solar energy during day time from the sun, the solar energy is stored in zeolites and when zeolites come in contact with a little amount of water the heat stored during day time is given out. This heat can be used to warm up water during night as well, giving access to hot water 24 hours in houses and hotels. Zeolite pellets, which can store up to four times more heat than water, loss-free for “lengthy periods of time.” Zeolites have extremely nonlinear adsorption isotherms to water.
AmXpO2p · nh2O = AmXpO2p+nH2O (endothermic) Since solar energy is stored and utilized here, it is clean and green source of energy and there is zero emissions for boiling or heating up water. What actions do you propose? Build a highly efficient zeolite powered water heater after conducting the necessary research and the principle suggested.

Introduction The use of solar energy for thermal applications can lead to significant reductions in the consumption of fossil fuels for both industrial and domestic use [1,2]. However, the variability of solar energy production represents a challenging issue [3]. The adoption of thermal storage can help to mitigate the daily solar power fluctuations, allowing to accumulate excessive energy during the peak production for later use [4].
In fact, storage allows to increase the efficiency of the solar systems, ensuring greater exploitation of this resource [5]. The three main technologies of thermal energy storage are: sensible, latent, and thermo-chemical heat storage. The sensible heat storage is characterised by the temperature increment of a material compared to a reference temperature. In latent heat storage, solar heat is accumulated due to the phase change latent heat and generally, solid–liquid transition is adopted. The structure of the paper is organised as follows. 2. 2.1. 2.2.
Thermal storage for the energy transition. Many roofs nowadays host solar collectors that provide homes with warm water. This works quite well in the summer; however, heating demand peaks in the winter when homes need heating. Thermal storage therefore needs to be able to store a portion of the excess heat for use at a later date. Traditionally, large water tanks have been used for this purpose; water is heated in these tanks and the heat is then directly stored as heat.
The problem with this method is that large volumes are required, and in spite of good insulation, heat is also lost. In contrast, thermochemical storage enables thermal energy produced in the summer to be preserved for use in the cold winter. Zeolites are one such storage solution. Unlike water, zeolites do not store the heat directly – instead, the heat removes the water that is stored within the material. Coating with aluminum Nevertheless, the researchers conquered these challenges. Frontiers | Water/Ethanol and 13X Zeolite Pairs for Long-Term Thermal Energy Storage at Ambient Pressure. 1. Introduction Thermal Energy Storage (TES) systems allow to store excess thermal energy and to use it at a later time (Zhang et al., 2016). TES has recently attracted particular attention in the renewable energy field, to match periodical or intermittent availability of renewable sources (e.g., solar) with continuous energy demand (Díaz-González et al., 2012; Engel et al., 2017; Bocca et al., 2018).
In this field, the design of efficient, reliable and economically-sustainable systems for thermal energy storage represents a major technological challenge to increase the renewable share on the global energy production (Ginley and Parilla, 2013). Thermal energy storage also finds application in the transport sector, for which a reduction of greenhouse gas emissions is foreseen by the recent international agreements on climate change mitigation (Schleussner et al., 2016; Xue et al., 2016). 2.

Search The Renewable Energy site for Do-It-Yourselfers The energy that is absorbed by a material as it turns from a solid to a liquid can be used to store heat energy for use at a later time in solar heating (or cooling) systems. This technique is attractive because 1) the heat is stored or returned over a very small temperature change, and 2) some phase change materials can store a great deal of heat in a small volume.

Contenu de la batterie externeDelta : Ditch the Batteries: Off-Grid Compressed Air Energy Storage. Compressed Air Energy Storage (CAES) is usually regarded as a form of large-scale energy storage, comparable to a pumped hydropower plant. Such a CAES plant compresses air and stores it in an underground cavern, recovering the energy by expanding (or decompressing) the air through a turbine, which runs a generator.
Unfortunately, large-scale CAES plants are very energy inefficient. Compressing and decompressing air introduces energy losses, resulting in an electric-to-electric efficiency of only 40-52%, compared to 70-85% for pumped hydropower plants, and 70-90% for chemical batteries. The low efficiency is mainly since air heats up during compression.
Why Small-scale CAES? In the previous article, we outlined several ideas – inspired by historical systems – that could improve the efficiency of large-scale CAES plants. The main reason to investigate decentralised compressed air energy storage is the simple fact that such a system could be installed anywhere, just like chemical batteries. Sans titre. Sans titre. There is an immediate objection; transmitting power by compressed air is horribly inefficent, because all the heat created in the compressor is lost long before the air gets to the point of use. Nonetheless the Paris network flourished for many years. Factory-wide compressed air networks for driving power tools are commonplace, but only Paris had a city-wide network.
The roots of the system go back to 1879 when the Austrian engineer Viktor Popp set up the Compagnie des Horloges Pneumatiques (CGHP)to drive pneumatic public clocks with one air pulse per minute, after authorization to install a compressed air network was granted by the City of Paris. At the time compressed air was in the air, so to speak, following the extensive use of compressed air for rock drilling in the construction of the Mont Cenis tunnel, which was initially expected to take 25 years but was opened in 1871 after only 14 years following the introduction of pneumatic equipment. Sans titre. Sans titre. Water pump operated by small air compressor turned with windmill blades This is a simple little pump with only 3 moving parts. A piston, piston return spring and exhaust piston/valve. The theory of operation is very simple. A small air compressor such as you get a any 'large-mart' that runs on 12 volts from your battery is dissassembled and the little electric motor exchanged for windmill blades.
It is then mounted on a frame and put on the top of a pole!. The small air compressors are generally rated as much as 250 psi but that will not be needed here. The pump is actually capable of working with the full output pressure of the compressor and pump water pretty high up if needed though - the pump would have to be built out of all metal for reliability though I think in that case... 1) The air from the compressor is fed on top of the piston forcing it down and pumping the water out. 4) The piston return spring to raises the piston back up refilling the pump casing with water.
Windmill with air compressor instead of electric generator (wind forum at permies) Bill Bianchi wrote:I've been looking into steam engines and gasifiers. They work to charge a battery bank, but it takes 4-6 hours and you need to actively run the engine as the batteries charge. (Batteries can accept only so much energy each hour without damaging them) So, I thought of using these engines to compress air. It wouldn't take more than an hour to fill a big air tank with an engine-powered compressor, would it? That doesn't seem too bad a run time for a steam engine or gasifier.
The air would run a pneumatic motor, which would run a generator that charges a battery bank. Couldn't I start the pneumatic motor and walk away while it charges the batteries? My thoughts are that having to maintain and generate (i.e. convert) energy through additional components would raise costs and lower efficiencies. A wood gasifier can be devised to operate at low power levels for extended periods, but there has not been good success here on anything but charcoal fuel. Sans titre. The major challenge in integrating wind energy into the electrical grid is that the resource is intermittent and unpredictable so that energy is always available.
With an energy storage system integrated with a wind turbine, surplus energy can be stored and then regenerated when demand is higher. In the proposed Compressed Air Energy Storage (CAES) system (graphics 1) energy is stored prior to electricity generation, eliminating the need and losses associated with generating electricity twice.
This also allows the electrical generator and transmission lines to be downsized for mean power instead of peak power. This can be a significant cost-saving for off-shore installations as their capacities are currently under-utilized by over 50%. Further savings comes from replacing a failure prone mechanical gearbox in the nacelle with a hydraulic pump, and installing the rest at the ground/sea level. Our system has two key innovations compared to a conventional CAES. Blog Archive » Solving the flexible biogas digester problems. You’d think that given the amount of cow dung available around rural Africa that biogas would be a big hit right?
Well, its actually relatively unknown. The main reason is materials, coast and complicated technology. People in these areas use charcoal or wood for their domestic cooking needs – its not only dirty hard work to collect firewood, but it’s unhealthy and damages the environment. But, it’s free … We believe that biogas from cow dung holds huge promise for rural and urban areas as a cheap source of energy that can be turned into domestic use or even business anywhere in rural Kenya….eg. pasturizing milk, making yoghurt, running fridges, generators, hammer mills for grinding corn, cooking, baking, heating water, running machines… and reducing your carbon footprint.
