Enter hydrogen energy!

Recently, the development of CNOOC's hydrogen energy industry has taken another step forward

This year, the development of the hydrogen energy industry has gradually accelerated.

Recently, CNOOC has also made new research breakthroughs in the preparation of hydrogen

On August 23, the China National Offshore Oil & Gas Group, a subsidiary of CNOOC, announced that the first skid-mounted natural gas hydrogen production device independently developed by China was officially put into use at the Foran Energy Mingcheng Comprehensive Energy Station

The skid-mounted natural gas hydrogen production device provides a better source of hydrogen energy for the wide application of hydrogen fuel vehicles in China

01Natural gas hydrogen production plan

In the context of carbon neutrality, in order to reduce carbon dioxide emissions, the global energy structure is shifting from fossil energy to renewable energy

In particular, in the face of wind and photovoltaic peak regulation and frequency regulation, the development of hydrogen energy as a secondary energy source has become an important choice

In March this year, the National Energy Administration issued the "Medium and Long-Term Plan for the Development of Hydrogen Energy Industry (2021-2035)"

With the support of top-level planning, major enterprises have also accelerated their pace in the development and utilization of hydrogen energy

In particular, more and more companies are participating in the research team with more efficient transformation, lower cost and more reasonable preparation schemes

Now, there are several ways to produce hydrogen: coal gasification, methanol reforming, natural gas, water electrolysis, and ammonia decomposition

The technological breakthrough of CNOOC is to use natural gas to produce hydrogen, which is achieved through joint research with Southwest Research Institute of Chemical Industry and Foran Energy

The device extracts gas from the gas pipeline to produce hydrogen.

The unit product consumption of the device, the compactness of the device and other indicators can reach the international advanced level

It is understood that the scale of natural gas hydrogen production at Mingcheng Station is 1,500 kg/day, which can meet the hydrogenation demand of 125 buses or 250 logistics vehicles

The technology has the characteristics of high integration, high degree of automation, high hydrogen production efficiency, small footprint, etc.

In addition, the device does not need to transport hydrogen from the hydrogen production plant or use long-distance pipelines to transport hydrogen to the site in application, which not only reduces the terminal cost of hydrogen by 20% to 30%, but also reduces the risk of hydrogen energy utilization
.

The skid-mounted natural gas hydrogen production device integrating many advantages provides a localized hydrogen source solution for the construction of the first batch of fuel cell vehicle demonstration city clusters in China, and has broad application prospects
.

02Another hydrogen production road

Regarding the development of hydrogen energy, since CNOOC entered the new energy field, it has repeatedly proposed to cultivate hydrogen energy.
For example, when it established the clean energy branch of CNOOC Energy Development Co.
, Ltd.
Clean energy such as hydrogen energy
.

In fact, in addition to natural gas hydrogen production, CNOOC's hydrogen plan also includes coal gasification to produce hydrogen
.

Moreover, CNOOC has also made some progress in the research and development of coal gasification for hydrogen production
.

CNOOC's research on coal gasification hydrogen production can be traced back to 2018, when CNOOC started to study coal gasification hydrogen production technology without any operating precedent and commissioning experience of similar coal-to-hydrogen plants
.

After four years of tackling key problems, the E-Gas coal-to-hydrogen combined unit has finally achieved safe and stable operation under different loads
.

This device has the characteristics of high carbon conversion rate, high heat utilization efficiency, low oxygen consumption, etc.
The most important thing is to reduce the cost of hydrogen production from gas by 20% to 25%
.

At the same time, the nitrogen oxides, sulfur dioxide, sewage and other pollutants of the device have achieved the discharge standard
.

The long-term stable operation of the device provides a new reference scheme for the development of coal-to-hydrogen in the world
.

03New hydrogen energy development space

In addition to hydrogen production from natural gas and coal gasification, CNOOC also has space for hydrogen energy development in the ocean
.

At present, offshore wind power is moving from shallow sea to deep sea.
While the total installed capacity of wind power is increasing, the problem of power consumption is also becoming more and more prominent
.

Especially in the deep sea, how to transmit the renewable energy power from the deep sea to the land is very important.
Since the cost of laying cables over long distances is too high, it is necessary to store the renewable energy power at this time
.

Under this circumstance, hydrogen production from offshore wind power has become an effective way to solve the problems of difficulty in integrating offshore wind power into the grid, and high cost of far-reaching power transmission
.

From this point of view, CNOOC has its own advantages in hydrogen production from offshore wind power
.

First, CNOOC has already deployed wind farms in the ocean, and is building deep-sea offshore wind power equipment, which can use offshore wind power to produce hydrogen on the spot with the help of wind farms
.

Second, seawater resources are abundant, and the use of offshore wind power to produce hydrogen and local materials can effectively reduce costs
.

For CNOOC, the development of offshore wind power for hydrogen production is also a new direction in line with the transformation of the energy structure
