California Energy Commission adopts offshore wind goals: 5GW by 2030, 25 GW by 2045

Green Car Congress

There are currently two federally-designated wind energy areas (WEAs) off the cost of California: Humboldt off the North Coast and Morro Bay off the Central Coast. However, the electric system in California’s North Coast region is relatively isolated from the California grid and serves primarily local community need.

DOE awarding $35M to 11 projects for hydrokinetic turbine development; ARPA-E SHARKS

Green Car Congress

Hydrokinetic energy is an abundant renewable resource that can boost grid resiliency and reduce infrastructure vulnerability, but it is currently a cost prohibitive option compared to other energy generating sources. These methodologies will significantly decrease the levelized cost of energy (LCOE) of the final HKT design.

DOE to award up to $180M for offshore wind demo projects; targeting lowering levelized cost of energy (LCOE) below 10¢/kWh

Green Car Congress

The demonstrations will help address key challenges associated with installing utility-scale offshore wind turbines; connecting offshore turbines to the power grid; and navigating new permitting and approval processes. waters in the most rapid and responsible manner possible; and.

KU Leuven team creates solar panel that produces hydrogen from moisture in air

Green Car Congress

If that electric power is used to split the water into hydrogen gas and oxygen, you lose a lot of energy. It is not connected to the gas grid. It only uses power from the grid in the winter. If all goes well, more panels will be installed on a piece of land in the street. —Johan Martens.

Understanding Demand Charges

Plug in America

Utilities introduced demand charges so that the costs of maintaining the power system are paid by those who require the most from the system. Commercial and industrial customers sometimes pay demand charges to account for their disproportionate impact on the grid based on how much electricity they use at any given time.
