Professor David Smeulders is simply wrong with his approach, that stopping with natural gas for home heating, increases CO2 emission.
He seems to reject recent climate science conclusons (IPCC SR15), that CCS is required to stay below 1,5 degrees global warming. And misses the concept of net metering.
This conclusion means that all fossil power plants have to become climate neutral.
Fossil power will become climate neutral, and a few cents per kWh more expensive.
At Dutch coal plants, this will be 2 to 3 cents.
These fossil power plants balance the power from renewable sources.
Because there is no cheap strorage of renewable power, other than in fossil fuels.
Net metering is key to social support for climate action
Net metering is already legally accepted and possible in the Netherlands, accepted, but politically blocked.
However, net metering is key to social support for CO2 reduction by citizens.
With net metering, and climate neutral fossil power plants, as balancing backup, homes and businesses, can heat their homes in a sustainable way, with their own, cheap renewable power. They will buy and own a lot of a wind or solar farm, and have their power at cost price, about 4 cents per kWh, because of the net metring regulations.
Cheaper than power from a fossil power plant, with CCS.
It works this way, because the grid is a shared resource, ad a public road for power.
Natural gas and power compared
10 kWh is the heat equivalent of 1 m3 natural gas
But that renewable heat costs about 40 cents, and natural gas costs about 80 cents today.
And this is without a heat pump, just a electric replacement of the gas heater in 90% of todays homes.
Homes and buildings that can work with the low temperature heat from a heat pump, eg in spring and autumn, will reduce their renewable energy consumption, because the heat pump amplifies heat energy from outside the home.
And in winter, the heatpump could be fed with stored heat from summer, from a soil based storage system,
This also reduces the load on local power networks
Stopping with natural gas at home, reduces CO2 emission
Stopping with decentral use of natural gas, is about CO2 reduction, not about sustainability. The climate problem is much more urgent than becoming a sustainable society. Keeping homes warm with renewable power from a wind farm or a large array of solar panels, eg on business buildings, is cheap. But net metering is required to get that cheap power at home.
A different approach is only replacing natural gas with hydrogen. The cheapest hydrogen is produced from fossil fuel. But to reduce CO2 emission, the conversion proces has to be extended with mandatory CCS. This hydrogen is more expensive than staying with natural gas, but its climate neutral. And older homes do not need the extensive and expensive insulation, that heat pumps require.
