In Germany, more than half of households use natural gas. Before the war, the price was relatively cheap. After the war began, natural gas became scarce and expensive, and many families were overwhelmed, some turned to heat pumps, some turned to wood stoves, and some could only bear high heating costs.

Companies that mainly engage in gas heating are also facing pressure and must find new business directions.

At the same time, climate change has also prompted countries to seek cleaner and more environmentally friendly energy.

In 2021, Germany cooperated with United Arab Emirates in the field of green hydrogen energy . In addition to planning to use hydrogen in automobiles, it is also planned to use it in industry.

and Honland , a heating company, BDR Thermea, plans to use hydrogen for heating. The company is trying to renovate existing natural gas pipelines and boilers to use hydrogen.

Many old houses, such as protected historical buildings, have poor insulation and are not easy to renovate, consume a lot of energy, and cannot use heat pump to replace gas heating. Therefore, switching to hydrogen is particularly beneficial for such a house.

This time, the company launched a pilot project: leveraging the existing natural gas network to supply hydrogen to 12 protected historic homes in the Dutch city of Lochem for heating.

Not only that, the company has a longer-term plan to make all its gas boilers use hydrogen.

Heat pump

In Germany, hydrogen heating is not on the agenda for the time being. One reason is that, according to energy experts, Germany will not have enough hydrogen for residential heating in the near future.

This expert believes that heat pumps are an important alternative to gas heating in the future. The German government is planning a regulation that starting from 2024, each new heating system, , will use at least 65% of renewable energy .

means that using green energy to power the heat pump, and the heat pump extracts heat from nature, the process is perfect.

is actually not so perfect. I haven't seen the sun for a long time. But in existing heating systems, the advantages of heat pumps are indeed obvious, especially in new buildings with better insulation.
