news & views the eventual transition to homogenous 3ʹ,5ʹ-linked genetic material. T echnologies for generating electricity from renewable resources, such as sunlight and wind, are on a steady trajectory of falling cost. Within the next decade, solar electric power is expected to reach grid parity, the point at which its cost will be equivalent (on a per-watt basis) to that of power generated fr...
Hydrogen-based fuel cells are promising solutions for the efficient and clean delivery of electricity. Since hydrogen is an energy carrier, a key step for the development of a reliable hydrogen-based technology requires solving the issue of storage and transport of hydrogen. Several proposals based on the design of advanced materials such as metal hydrides and carbon structures have been made t...
in most of the developing countries, particularly in asian countries, the initial step of electricity industry restructuring has begun by spot market design. in addition, electricity industry, all around the world, is approaching competitive markets. meanwhile there are many unanswered questions including deregulation mechanism. in this new framework, producers are considered as private compani...
The economics, infrastructure, transportation, and level of living a country are all influenced by energy. gap between energy usage availability is global issue. Currently, countries rely on fossil fuels for generation, these not sustainable. hydrogen proton exchange membrane fuel cell (PEMFC) power system both clean efficient. delivery the PEMFC make up majority system. lack an efficient, safe...
heat exchangers are the critical components of refrigeration and liquefaction processes. selection of appropriate operational conditions for cryogenic recuperative heat exchanger and expansion valve operating in joule-thomson cooling system results in improving the performance and efficiency. in the current study, a straightforward procedure is introduced to design an efficient joule-thomson co...
environmental pollution by 2,4-dicholorphenol (2,4-dcp), commonly found in industrial wastewater has been a concern for humans over the past 50 years. garden radish peroxidase (grp) can eliminate this poisonous pollutant. the aim of this study was to apply an experimental response surface methodology (rsm) and central composite design (ccd) to optimize grp-based treatment in order to maximize ...
Hydrogen technologies and infrastructures might play a significant role in meeting ambitious climate and energy policy goals of the UK Government. Nonetheless, studies on hydrogen are either limited in scope in that they do not take into account the relationships with the wider energy system drivers and constraints or do not consider how a hydrogen network might develop geographically. This pap...
Contemporary off-grid mining operations rely on diesel fuel for the provision of their total energy including electricity, heat, and haulage. Given high cost its imposed greenhouse gas emissions, companies are looking more affordable cleaner sources operations. Although renewable systems, such as solar photovoltaic wind provide efficient solutions to address this challenge, full decarbonization...
This paper conducts an in-depth analysis of the electricity-hydrogen coupling under high-permeability renewable energy scenario, and further proposes that production hydrogen from electrolyzed water is a key link in scenario. Analysis issues technical routes other aspects, finally put forward development suggestions for scenario energy.
with the aim of reducing cost of electricity consumption and peak load reduction, tools requirement for better managing electricity consumption have become inevitable in recent years. smart home has some equipment which are controllable and this ability is used for increasing comfort and minimizing electricity cost for residence. as a key component of smart home , electric vehicle(ev) ,increase...
