Our impact: high-quality carbon dioxide removal

We remove CO2 today – and even more tomorrow. And we measure, report and verify every tonne of our carbon removal thoroughly.

neustark removes CO2 permanently and delivers tangible climate impact

To achieve net-zero by 2050, it is critical that we reduce as much as we can and then we remove the rest with truly additional, high-quality, and highly permanent carbon removal.

Neustark is the first company to have shown in practice that permanent CO2 storage via mineralization in demolished concrete is both commercially and ecologically viable.

And the first to deploy its solution at various sites across Europe – already removing CO2 today, and even more tomorrow.

We are now successfully scaling up our operations – i.e. the number of source and sink sites operated. And, ultimately, and our impact in the number of tonnes of CO2 we store.

We’re on our way to removing hundreds of thousands of tonnes of CO2 in this decade, and beyond.

How efficient are our plants?

Dedicated life cycle assessments show that our technology reaches a carbon removal efficiency of 93% over its whole lifespan. This means that a typical neustark plant re-emits around 7% of the carbon dioxide it captures.

Of course, we strictly sell the net carbon removal of our plants, meaning that we compensate for these (very low) grey emissions.

The chart below shows the cumulative emissions of the value chain (in black), including the negative emissions of the mineralization plant (in orange).

How do we calculate the number of tonnes we remove?

Simply put: 

# tonnes of CO2 net removed = # tonnes injected – leakage – process emissions 

As an example, if we capture 1 tonne – so 1000 kilos – of CO2, liquefy it and transport it using bio-fueled trucks, then inject it into demolished concrete, we will have permanently removed around 930 kg of CO2.

As the chart above shows, the most energy-intense phase of the process is the liquefication. Transport and our storage technology also consume energy. And a marginally small percent (<5%) of the CO2 we capture and store leaks back into the atmosphere.

Neustark strives for the highest quality of our CDR. We rigorously report our impact every year – and have it validated by a third party.

Our impact – in 2030 and beyond.

Our ambition is to have removed hundreds of thousands of tonnes of CO2 in this decade. And, of course, beyond that: we aim to increase our impact every year, also exploring and deploying new carbon removal methods.

Our target is ambitious, yet realistic. And we’re well on our way. To achieve that goal, exponential growth is needed. We are currently massively scaling-up our operations: the number of source and storage sites in operation as well as our geographical reach.

Scientists project that we will have to remove around 10 gigatonnes – i.e. 10,000,000,000 tonnes – of CO2 per year. Neustark removing hundreds of thousands of tonnes of CO2 in this decade – and even more in the years after – is a significant part of that puzzle.

What’s more, we strive to help develop the CDR market to make trusted and effective carbon removal a given in the next decade. For a bright future of all generations on our planet.

MRV: verifying our projects and impact

We know that carbon removal is an essential tool for meeting our climate targets. But scale is only part of what’s required to make a lasting impact – we also need trust.

CDR solutions need to be verifiable, which requires the development of standards to quantify their impact. This is what the field of monitoring, reporting, and verification, short MRV, is aiming to do.

Neustark strives for the highest quality of our CDR, and we place the topic of MRV at the core of our development. We want to bring measurability and accountability to the field, leading the CDR ecosystem to the highest level of trust and integrity.

We have partnered with Gold Standard to establish the world’s first (and to date only) methodology for tech-based carbon removal. We rigorously report our impact every year – and have the CDR of each of our sites validated by a third party.

FAQs

  • Durable means: the fraction of carbon dioxide stored through mineral carbonation that is retained after 1000 years is virtually certain to be 100%. The risk of reversal, i.e. that the carbon sequestered is released again into the atmosphere, is negligeable. Even if the concrete in which the CO2 is injected gets demolished again and again, the CO2 will not be released into the atmosphere.

    Neustark’s solution is highly permanent, binding CO2 for thousands to millions of years.

  • Additionality means that the removals in emissions achieved by the project must be “above business as usual". That means they would not have happened unless the project was implemented.

  • A quality carbon credit means one ton of carbon dioxide has been reduced or removed from the atmosphere. It also means that this reduction or removal has been certified under an internationally recognized carbon standard – such as Gold Standard.

  • Our process does not interfere with natural ecosystems. It requires only a very small area as it is integrated into already existing industrial processes.

  • The central benefits of storing CO2 in demolished concrete is that the CO2 is irreversibly bound to the concrete granules via the mineralization process. The major advantage of this approach over natural carbon sinks (e.g., ocean, trees) is that the embodied carbon in concrete has no chance of returning into the atmosphere. In other words, carbon dioxide is permanently stored inside the concrete.
