About CEI

Who are Clean Energies Investor?

Clean Energies Investor is a renewable energy investment firm that supports and funds developing sources of renewable energy with high growth potential, such as Compact Anaerobic Digestion (AD).

Its goal is to advance and scale new sources of renewable energy by helping bio-tech pioneers commercialise their technologies for clean energy production.

Clean Energies source, build and operate the plants it funds to stay as close to the investment as possible.

Does Clean Energies Investor specialise in only AD or are there other types of projects it’s involved in?

Clean Energies Investor is presently focused on realising the commercial potential of Compact AD in the UK.

There are still strong commercial opportunities within the UK Compact (sub 250kW) Anaerobic Digestion (AD) sector even with UK government tariff degradations.

Compact AD has advanced significantly in the past few years – both from a biotech and industrialisation perspective – and there are now efficient and reliable modular technologies and plants that are well suited to the UK landscape and farming sector.

Clean Energies Investor hold a strategic / development partnership with UK BioTech pioneers New Generation Biogas who have developed a modular two stage thermophilic system Compact AD plant process and system that can operate on waste alone and is x6 faster and 30% more efficient than conventional AD plants. A 200kW plant can be supported with 400+ cattle (and other livestock).

Are you UK based or International?

Clean Energies Investor is a UK based renewable energy investment firm – we fund and scale developing sources of renewable energy with strong growth potential in both the UK and Europe.

What is Anaerobic Digestion (AD)?

Anaerobic Digestion is the natural degradation of organic waste in the absence of oxygen into biogas (methane and carbon dioxide) and digestate (a natural fertiliser).

The UK produces over 110 million tonnes of farm waste from approximately 200,000 farms every year. And today in the UK, we spend over £100 million every year on waste management – household, human and food.

For decades, managing waste has been a challenging and costly affair for our country and our economy. But waste has an in-built value – energy. And by harnessing a natural process by which waste degrades into digestate (a natural fertiliser) and biogas, Anaerobic Digestion (AD) – we can potentially create terawatts of clean energy for UK homes and industry.

In fact, if we converted all 110 million tonnes of farm waste into energy, we would produce over 80 TWh of clean energy each year – enough to power tens of millions of homes in the UK.

Hasn’t the UK government removed all subsidies for renewable energy in the UK now?

The UK Government has degraded subsidies for mainstream renewable energy such as solar and on shore wind and is currently exploring reducing the subsidies (Feed in Tariffs or FiTs) for AD as well.

However, at present these subsidies are still in place for Conventional and Compact AD in the UK and once an AD site has received pre-accreditation its FiTs subsidies and so future revenue projections are locked in.

While the UK Government is planning to reduce FiTs subsidies for AD, the sub 250kW sector (known as small or Compact AD) will be less hard hit by the reductions which are aimed more at medium and large scale AD of 500kW / 1MW+.

With government subsidises for renewable energy sources, why does it need my investment?

Government subsidies play an important role in providing economic certainty for renewable energy projects – encouraging early-stage private investment towards publicly beneficial sectors. In the case of renewables in the UK, subsidies are centred on revenues for operational projects – providing a minimum level of income for successful construction.

Private investment is key to building renewable energy sites – getting plants operational and therefore eligible for government subsidies. Clean Energies Investor look to scale private investment such that our technology partners lower their costs to the point at which subsidies are no longer necessary.

Where does my money go once it’s with Clean Energies Investor?

Clean Energies Investor brings together technology providers, project managers and site-owners (usually farmers) to build Compact AD plants in the UK. The company has excellent ongoing relationships (including exclusive rights) with emerging technology providers and project managers; therefore the investment process usually focuses on new site-owners.

The process begins with registering interest from potential site-owners, including a formal check list of necessary conditions for a new site. Once the site has been selected and heads of terms agreed, project management begin the construction process. Approximately 6-9 months from the beginning of construction, the plant is fully operational.

Clean Energies Investor provides funding for the construction of the plant, staged appropriately to achieve efficient completion. Once the plant is completed and operational, Clean Energies Investor’s funding is gradually repaid through operational cash flows or through refinancing. These investment proceeds are then used for other sites.


How secure is your investing site?

Clean Energies Investor use ShareIn Limited to deliver our bond platform. ShareIn are authorised and regulated by the UK Financial Conduct Authority (FRN 603332).

How secure is my Investment?

The capital raised through our high yielding bonds will be used to fund the construction of Compact Biogas plants across multiple farm sites in the UK.

The Bond investments are fully secured against real renewable energy assets in the UK (Biogas plants), underpinned by long term government income, which if the Bond coupon is not paid within 14 days, will be taken as security by the Trustee on behalf of the Investors.

What are the risks involved?

As with any Bond investment, the main investment risk is an inability to pay interest and principal. In Clean Energies Investor’s case, this would likely be due to operational failure of one or more projects. The company mitigates this risk through scaling multiple plants and using multiple technology partners.

Prospective investors must ensure that they are fully aware of the nature of this type of investment before committing to invest. Prospective investors should carefully consider the risk factors together with all the information available in our Bond invitation and on our website.
