Germany verifies "electricity gas": converting surplus photovoltaic electricity into hydrogen

Recently, RWE, a large German power company, announced that the high-efficiency "Power-To-Gas" demonstration equipment has begun operation
.
It is reported that "electricity production gas" refers to the use of renewable energy electricity such as surplus electricity from photovoltaic power generation to produce hydrogen, methane and other gases
.
By converting electricity into hydrogen or methane for storage, surplus electricity
from renewable sources can be effectively utilized.
RWE believes that this technology is one of the
important technologies for future energy supply.

The demonstration facility for "electric gas production" is located in Ibbenburen in the western German state of North Rhine-Westphalia (NRW
).
According to reports, this is the first equipment
integrated with the local power grid, gas supply network and heating network.

The "electricity to gas" verification experiment will use the surplus electricity from photovoltaic power generation and wind power generation to produce hydrogen from water, and store the produced hydrogen in the
gas supply network.
Hydrogen will then be used for electricity production
with higher operating rates.
Hydrogen generated from surplus electricity is first stored and then taken out to convert it into electricity
when needed.

The German government has proposed a plan
to use renewable energy to meet 50% of the country's electricity demand in 15 years.
This is about twice as high as the current ratio
.
In order to achieve this goal, it is necessary to implement conversion technologies that can respond to changes in renewable energy output and improve the efficiency of
energy storage.
In this regard, RWE believes that "electricity to gas" is a more effective way and positions it as one of the
important technologies for future energy supply.
