China plans to expand renewable energy beyond the power sector

China's Energy Administration said Wednesday that the country will expand its efforts beyond the power sector in the next five-year period.

In its opinion paper on integrating new energies, the National Energy Administration (NEA), said that provinces and power producers must help local governments build their industrial base for green hydrogen and green ammonia. Green hydrogen is produced by using renewable electricity in a chemical reaction to split water molecules into hydrogen and oxygen. It can be used as a fuel for heavy industry, transport and industrial processes, or to power vehicles. It also serves as a source of ammonia and other chemicals, such as methanol and fertilisers.

The Department encouraged coastal areas in the United States to investigate using offshore wind power to produce hydrogen. This is a relatively new production method.

The document called for the use of renewables in heating, especially in industrial parks. Energy planners consider low-carbon industrial park as key to decarbonisation because the industry consumes 60% of the electricity in the country, according to International Energy Agency.

The need to find new outlets for renewable energy is growing urgent, as China's fleet - the largest in the world - sometimes produces more electricity than can be accepted by the grid, a situation known as curtailment. This is likely to be the focus of energy regulators in the next five-year plans. Wood Mackenzie, an energy consultancy, forecasted recently that the solar curtailment rate would average over 5% in China's 21 provinces within the next decade. This is an increase from the 10 provinces that experienced this level of curtailment between January and August of this year. However, it still falls within China's 10% national limit.
