With the increasing dependence of society on energy, from the perspective of sustainable development, energy storage and conversion technology and its application have become increasingly urgent. Energy Storage and Conversion (ESC) is an open access peer-reviewed journal, and focuses on the energy storage and conversion of various energy source. As a clean energy, thermal energy, water energy, wind energy, ammonia energy, etc., has become a key research direction of the international community, and the research of energy storage system has been extended to the field of energy conversion applications. Solar cells, for example, have made significant progress in efficiently harvesting solar energy and efficiently converting various fuels into electricity. Scopes of the Journal include, but are not limited to:

  • The theory and application of new energy;
  • The equipment and applications of energy storage;
  • Research on the utilization of renewable energy sources;
  • Conversion equipment, process, materials, and technology research;
  • Multi-energy storage and conversion combination, integration and other solutions;
  • Reliability, safety and performance analysis of energy management systems, etc.

    The performance evaluation of a screw type dewatering system for bio-digestate in Nepal demonstrates significant potential for improving the usability and efficiency of bio-digestate as a fertilizer. Remarkable modifications in the previous include a 5 HP motor running at 1440 RPM with a gear reduction ratio of 1:40, a spring assembly system at the outlet, and a fine sieve. Testing and performance analysis at different operating speeds using a variable frequency drive revealed an optimal performance at 8 RPM, where the system achieved a liquid yield of 92.02% and an extraction efficiency of 73.12%. The installation cost of the machine was NPR 384,000, with a payback period of 2 years, six months, and two days. The internal rate of return (IRR) was calculated at 28.53%, while the net present value (NPV) was NPR 179,006.35. This study indicates that operating the dewatering system at lower speeds may improve efficiency and effectiveness in the dewatering process. This makes the machine a viable option for producing organic fertilizer and addressing Nepal’s significant need for fertilizer.
