Abstract

The invention discloses an electricity, water, hydrogen and methanol poly-generation energy island and method, and belongs to the technical field of energy utilization. The energy island comprises a flue gas water extraction electricity and water co-generation system, a coupling power generation hydrogen production and storage system and a carbon collection methanol production system. The electricity, water, hydrogen and methanol poly-generation method specifically comprises the following steps: 1) a carbon neutralization method in an energy island; 2) a zero water taking method; and 3) a wind-light-fire coupling energy-saving power generation method. According to the energy island provided by the invention, green electricity hydrogen production is integrated by recovering flue gas condensate water, carbon dioxide is further recovered, meanwhile, methanol is produced by green electricity, green electric energy gap is compensated by peak regulation balance electric quantity in the island, and zero water taking outside the island and carbon neutralization in the island are realized by coupling an electricity-water poly-generation unit with a wind turbine generator and photovoltaic power generation.

Description

technical field [0001] The invention relates to the technical field of energy utilization, and more specifically relates to an electricity-water-hydrogen-methanol polygeneration energy island and a method thereof. Background technique [0002] my country's power energy is dominated by thermal power generation. The annual carbon dioxide emissions of the thermal power industry reach 4.5 billion tons, and the annual water consumption of the national once-through cooling thermal (nuclear) power plants reaches 47.9 billion cubic meters. In terms of energy consumption, the annual electricity consumption of thermal power plants accounts for about 6% of the power generation (i.e. power consumption rate). At the power point level, taking individual power points as an example, two thermal power plants with an installed capacity of 660,000 kilowatts have an annual power generation and water intake of 2 million cubic meters, and the annual carbon dioxide emissions from power consumption...
