AD plant income

Hi,

I'm considering setting up an AD plant next to my farm. After some research i've found that I can earn some money from the government (feed-in-tariffs, RHI etc) and also sell the gas.

From people who would know, are there any other sources of revenue?

Thank you

How can you get FiT and RHI when you sell the gas, surely you need to run an engine with the gas to get the Fit and RHI?

Exactly my point, you can't get either without running the engine.
The OP say 'selling the gas'.
How can he sell the gas and earn FiT and RHI?

I know what you mean but you could be more efficient with your AD plant and incorporate solar panels in the design for both heating the digestate and direct PV which would give you both RHI and Fit income leaving the gas for direct injection into the grid.No engine required.

That was ( in part) where I was coming from with my OP about AD for gas for sale.
I have a large diesel genny installed now for STOR, etc and it has a parasitic load for its block warmer etc , I want to build a new 80 cow robotic dairy next to it which has uses about 5k of leccy per year, my thinking was put a micro AD plant in, and put(at the last minute before FiTs disappear) PV on the new shed roof to service the Genny, dairy and heat the AD slurry but not necessarily run an engine to make a more simple system.

Sounds to me like you could use AD and solar to charge batteries and use the stored energy as part of stor. If you have a big enough grid connection for Stor you could use batteries as an income. Top up batteries with own generation, buy in electric when cheap and sell electric via demand response or when price for elec is high

You need a minimum of 80,000 export on solar to make storage work. I can’t make it work with 50,000 export on 150kW solar demand around 40kWh.

Batteries are dead sadly until the gov change their policies or the install cost drastically falls, which it will, I’m sure, one day
Cost, those RedT 45/225 retail at £180,000 ish, grant £71,000 leaving £109,000.

This will only work if cost is £50,000 otherwise 14 year payback. This is taking into account 50,000kWh solar donation. Power shifting off peak to peak costing is pityful. Relying on grid to fill then use at peak using 225kW storage is laughable and non profit for business.

In fact, if storage is used on site you need a monster 250kW to suit 45kWh/225kW storage with export 50% and if you haven’t sucked up the low voltage network then another £60k upgrade

So you agree!?

I’m working with a company on a big gas turbine project, they seem to be Up to their eyeballs in this and have parked up their battery projects for now.
Yes, currently as I’ve said before you need a ratio of 5:1, energy produced versus storage. One issue is that the set up will only allow a 2:1 ratio.

Secondly, problem for farmers is they’re usually riding their maximum supply especially the ones that kept telling me to fill the roof for maximum fit. They then don’t have enough capacity for storage as I’ve learnt and then they need 60k upgrade investment on top of the expensive storage. Non starter for 10 straight off the start block.

So people, do your homework very carefully if you’re looking at storage and always get your accountant to check figures or post here.

Interesting thread, despite the new OP asking about income from AD (which seems strange) The thread then moves off in the PV direction where much of the information being posted is simply wrong.

So what do you do with the biogas produced ? In addition where does the heat for the digester come from ? when you say PV, do you mean ceramic ?

It’s so irritating when people think they see errors in a post yet don’t highlight the facts as they think they know. At least address the point you object to I have hairy balls not crystal balls!

The comment was to highlight the unnecessary hijacking of a thread, in addition my intention was not to irritate. Then I thought about letting you know where the wrong information is being given, but then changed my mind........

So, when the thread diversified evolving to include future planned addition of storage with a reply advised to look closely at the cost versus utilisation of power shifting electricity. In your infinite wisdom without explanation decided that some section was irrelevant with incorrect information without explaining what, where, when and why, then cultivating an even more irritable emotion decide to repeat a strawman argument to engage such emotion.

I’ll reiterate my response; you’re pathetic.

as thesilentone asks.... and this is the main crux of this threat.... what do you plan to do with the biogas produced?
you've got to do something with it to be able to claim any of the support tariffs and at the simple end of the scale there are only two ways to use it - engine or biogas boiler
forget any of the other uses i.e gas to grid etc as they are only for big operations
