Fukushima Hydrogen Energy Research Field (FH2R) completed in Japan; aiming for low-cost green hydrogen production; P2G

Green Car Congress

Renewable energy output is subject to large fluctuations, so FH2R will adjust to supply and demand in the power grid in order to maximize utilization of this energy while establishing low-cost, Green hydrogen production technology. With sights set on expanding the use of renewable energy, Toshiba ESS, Tohoku Electric Power Co.,

Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

Quinones are naturally abundant, inexpensive, small organic molecules, and similar to molecules that store energy in plants and animals. The technology could fundamentally transform the way electricity is stored on the grid, making power from renewable energy sources such as wind and sun far more economical and reliable. Background.

Heliogen and Bloom Energy demonstrate production of low-cost green hydrogen; concentrated solar and high-temp electrolysis

Green Car Congress

Heliogen’s concentrated solar technology is different than traditional photovoltaic solar; it facilitates hydrogen generation for longer periods of time, operating near 24/7 by storing the solar energy, resulting in more compact and lower cost production.

To Store or Not to Store: That is the Question

Green Car Congress

This has led to a change in thinking of how energy generation is optimized and a new strategy has developed in which flexible energy generating sources are deployed to meet peak requirements while maintaining a steady state base load from low cost less-flexible solutions. This is demonstrated in figure 1.

Exeter team develops low-cost photoelectrode for spontaneous water-splitting using sunlight

Green Car Congress

A promising way of storing solar energy is via chemical fuels, in particular hydrogen as it is considered as a future energy carrier. The greatest challenge is to develop a suitable technology for large scale and cost effective solar fuel production to compete with fossil fuel.

Fraunhofer researchers develop new low-cost dry-film electrode production process

Green Car Congress

First, they mix the active materials, intended later to release the stored energy, with additives to create a paste. Until now, cell producers have mostly coated their battery electrodes in a complex wet-chemical process. In this process they add organic solvents, which are expensive and usually toxic.

PNNL team develops new low-cost method to convert captured CO2 to methane

Green Car Congress

The authors’ assessment identified further cost savings, in that CO 2 captured by EEMPA can be converted to methane on site. Traditionally, CO 2 is stripped from water-rich solvents and sent off site to be converted or stored underground.
