The German energy transition makes it necessary to increase flexibility in the electricity system. Different forms of power storage may play a part in this, yet there is competition with other options on the production or demand side. In the short term, the further expansion of electricity...

The increasing importance of renewable energy, especially solar and wind power, has led to new forces in the formation of electricity prices. Hence, this paper introduces an econometric model for the hourly time series of electricity prices of the European Power Exchange (EPEX) which...

In contrast to conventional hydrothermal systems or enhanced geothermal systems, CO2 Plume Geothermal (CPG) systems generate electricity by using CO2 that has been geothermally heated due to sequestration in a sedimentary basin. Four CPG and two brine-based geothermal systems are modeled to...

This paper analyzes regional interdependencies and trajectories of the energy and agriculture sectors in Germany's Northwest Metropolitan Region in order to assess the performance of regional low-cost and low-carbon strategies to alter energy sector profiles in the light of changing...

More and more attention is being paid to renewable technologies because they are seen as a great opportunity to disengage our society from its dependence on fossil fuels. Such flow-based energy resources that rely on solar energy are supposed to lead us toward a sustainable energy future....

This paper aims at discussing the renewable energy potentials in delivering parts of the energy needs in Cameroon. The country has an enormous renewable energy potential. The lack of clear renewable energy policy in the mix is an issue that needs to be addressed urgently by the Cameroonian...

Although both promoted as sustainable, nuclear and renewable energy elicit different evaluations in people. People expect (whether true or not) different implications for the environment and for consumers' resources from these energy alternatives. But what factors define the perceived importance...

The chemical potential difference of two liquids with dissimilar salinities can produce electrical energy using salinity gradient power (SGP). The pressure-retarded osmosis (PRO) concept can be used to generate SGP across a semi-permeable membrane. This work describes a mathematical model for...

The potential of lithium ion (Li-ion) batteries to be the major energy storage in off-grid renewable energy is presented. Longer lifespan than other technologies along with higher energy and power densities are the most favorable attributes of Li-ion batteries. The Li-ion can be the battery of...

Inlet cooling is effective for mitigating the decrease in gas turbine performance during hot and humid summer periods when electrical power demands peak, and steam injection, using steam raised from the turbine exhaust gases in a heat recovery steam generator, is an effective technique for...
