Can micro-CHP systems solve the solar intermittency issue?
In order to solve the solar intermittency issue, several studies questioned the feasibility of hybrid systems. By integrating renewable sources such as solar, geothermal, biogas and biomass, micro-CHP systems could be an efficient way to introduce renewables in several areas of applications such as residential and industrial environments.
What are the efficiencies of a micro-CHP system?
The system efficiencies are typically 80% and the emissions low enough to satisfy the ever tightening requirements related to air quality. The schematic below is a representation of a micro-CHP system.
What is the market potential for micro-CHP?
The development of micro-CHP technology has progressed at a rapid rate with over thirty companies throughout the world working on the deployment of such products. This amount of research and development indicates that there is significant market potential for micro-CHP throughout the world. Electrical Efficiency 10-20%. SOFC (Solid Oxide)

What is a micro CHP system?
Micro CHP systems allow highly efficient cogeneration while using the waste heat even if the served heat load is rather low. This allows cogeneration to be used outside population centers, or even if there is no district heating network. It is efficient to generate the electricity near the place where the heat can also be used.
What conversion technologies are used in micro CHP systems?
A number of different conversion technologies have been developed for the application in micro CHP systems. Reciprocating engines are conventional internal combustion engines coupled with a generator and heat exchangers to recover the heat of the exhaust gas and the cooling cycle.
What is micro-CHP?
Micro-CHP consists in a distributed generation of heat and power at small power scale (<50 kW e ). Producing locally heat and power reduces transport losses that occur in centralized production and participates to the consumer’s individual awareness.
What is the power size of a micro CHP system?
The Micro CHP systems based on Rankine cycles (which use water or an organic fluid as the working fluid) with a power size of up to 10 kW, which are mostly available on the market at a prototype level only, have an electric power size ranging from 1 kW to 10 kW, with a corresponding thermal power size ranging from 8 kW to 44 kW (Fig. 14).
Which companies offer micro CHP based on reciprocating engines?
Other companies offering micro CHP products based on reciprocating engines include Power Plus (recently purchased by the boiler company Vaillant) with its 4,7 kWel Ecopower module, capable of modulating its capacity (see Figure 11 and Table 6). Ratio between thermal and electrical output is approximately constant over the total power output.
How many micro-CHP systems are there in the UK?
It is estimated that about 1,000 micro-CHP systems were in operation in the UK as of 2002. These are primarily Whispergen using Stirling engines, and Senertec Dachs reciprocating engines.

Thermal energy storage Nepal
Energy is an essential commodity. Rapidly increasing populations and economic growth are causing global energy demand to increase, especially in emerging-market economies. Energy supply is interwoven with global warming, local pollution, national and international security, economic growth and the ability to meet. . Traditionally, energy from biomass has dominated the domestic energy supply for most people in Nepal and oil was important for motorized transport. However, electricity is. . Balancing high levels of variable solar energy over every hour of every year is straightforward. Storage via batteries and pumped hydro allows the daily solar cycle to be accommodated.. . Government energy roadmaps in many countries are being overtaken and rendered obsolete by a sustained rapid decline in the cost of solar energy and sustained rapid growth in solar-energy deployment. New solar. [pdf]FAQS about Thermal energy storage Nepal
Can solar power power the Nepalese energy system?
Nepal has vast low-cost off-river pumped hydro-energy-storage potential, thus eliminating the need for on-river hydro storage and moderating the need for large-scale batteries. Solar, with support from hydro and battery storage, is likely to be the primary route for renewable electrification and rapid growth of the Nepalese energy system.
Can pumped hydro be used to store energy in Nepal?
For several hours, overnight and seasonal storage, pumped hydro is much cheaper. Batteries and pumped hydro are complementary storage technologies. Hydrogen production in Nepal is unlikely to be significant. Hydrogen or hydrogen-rich chemicals such as ammonia could be used to store and transport energy in Nepal.
Does Nepal have a potential for off-river hydro storage?
Nepal has enormous potential for off-river PHES. The Global Pumped Hydro Storage Atlas [42, 43] identifies ~2800 good sites in Nepal with combined storage capacity of 50 TWh (Fig. 6). To put this in perspective, the amount of storage typically required to balance 100% renewable energy in an advanced economy is ~1 day of energy use .
Why is thermal energy storage important?
Thermal energy storage (TES) is increasingly important due to the demand-supply challenge caused by the intermittency of renewable energy and waste heat dissipation to the environment. This paper discusses the fundamentals and novel applications of TES materials and identifies appropriate TES materials for particular applications.
Why should we study pumped storage systems in Nepal Himalayas?
Nepal Himalayas provide an ideal testbed to study pumped storage systems given high topographic gradients, large flow fluctuations, and prevalent energy demand patterns.
Could hydrogen be used to store and transport energy in Nepal?
Hydrogen production in Nepal is unlikely to be significant. Hydrogen or hydrogen-rich chemicals such as ammonia could be used to store and transport energy in Nepal. However, this is unlikely to occur because the efficiency is very low compared with those of batteries, pumped hydro and thermal storage, which unavoidably translates into high costs.
