Analysis of US renewable fuels policies using a modified MARKAL model

Renewable fuels

Renewable Liquid Fuels

B ecoming independent of crude oil imports, mainly from the Middle East, is an urgent concern for many countries all over the world. In order to secure a sustainable energy supply, especially in the transportation sector, governments need to apply policies that promote the use of renewable energy technologies. The dependence on crude oil imports decreases as the production of total energy from ...

Plasmatron Reformation of Renewable Fuels

The characteristics of plasmatron reformers for the generation of hydrogen rich gas using renewable fuels is discussed. Biodiesel and ethanol have been investigated. Operating as a function of the air/fuel ratio is evaluated, as well as the impact of the plasma.

1 Us State Policies for Renewable Energy : Context and Effectiveness

Over the past decade, state policies on renewable energy have been on the rise in the United States, providing states with various options for encouraging the generation of renewable electricity. Two promising policies, the Renewable Portfolio Standard (RPS) and the Mandatory Green Power Option (MGPO), have been implemented in many states but the evidence about their effectiveness is mixed. In ...

Power injection of renewable energy sources using modified model predictive control

This paper presents a simple model predictive control (MPC) approach to control the power injection system (PIS) for renewable energy applications. A DC voltage source and a single-phase inverter that is connected to the grid by an LCL filter form the PIS. Grid voltage is considered a disturbance for the system. For eliminating this disturbance, a modified model is proposed. It is usual to ...
